dfa1e1dd53 Convert libxl driver to Xen 4.2
Based on a patch originally authored by Daniel De Graaf

  http://lists.xen.org/archives/html/xen-devel/2012-05/msg00565.html

This patch converts the Xen libxl driver to support only Xen >= 4.2.
Support for Xen 4.1 libxl is dropped since that version of libxl is
designated 'technology preview' only and is incompatible with Xen 4.2
libxl.  Additionally, the default toolstack in Xen 4.1 is still xend,
for which libvirt has a stable, functional driver.

705e67d40b network: allow guest to guest IPv6 without gateway definition
This patch adds the capability for virtual guests to do IPv6
communication via a virtual network interface with no IPv6 (gateway)
addresses specified.  This capability has always been enabled by
default for IPv4, but disabled for IPv6 for security concerns, and
because it requires the ip6tables command to be operational (which
isn't the case on a system with the ipv6 module completely disabled).

This patch adds a new attribute "ipv6" at the toplevel of a <network>
object.  If ipv6='yes', the extra ip6tables rules required to permite
inter-guest communications are added when the network is started. If
it is 'no', or not present, those rules will not be added; thus the
default behavior doesn't change, so there should be no compatibility
issues with any existing installations.

Note that virtual guests cannot communication with the virtualization
host via this interface, because the following kernel tunable has
been set:

   net.ipv6.conf.<bridge_interface_name>.disable_ipv6 = 1

This assures that the bridge interface will not have an IPv6
link-local (fe80::) address.

To control this behavior so that it is not enabled by default, the parameter
ipv6='yes' on the <network> statement has been added.

Documentation related to this patch has been updated.
The network schema has also been updated.

a2d2b80fbd Add Gluster protocol as supported network disk backend
This patch introduces the RNG schema and updates necessary data strucutures
to allow various hypervisors to make use of Gluster protocol as one of the
supported network disk backend. Next patch will add support to make use of
this feature in Qemu since it now supports Gluster protocol as one of the
network based storage backend.

Two new optional attributes for <host> element are introduced - 'transport'
and 'socket'. Valid transport values are tcp, unix or rdma. If none specified,
tcp is assumed. If transport is unix, socket specifies path to unix socket.

This patch allows users to specify disks on gluster backends like this:

    <disk type='network' device='disk'>
      <driver name='qemu' type='raw'/>
      <source protocol='gluster' name='Volume1/image'>
        <host name='example.org' port='6000' transport='tcp'/>
      </source>
      <target dev='vda' bus='virtio'/>
    </disk>

    <disk type='network' device='disk'>
      <driver name='qemu' type='raw'/>
      <source protocol='gluster' name='Volume2/image'>
        <host transport='unix' socket='/path/to/sock'/>
      </source>
      <target dev='vdb' bus='virtio'/>
    </disk>

4201a7ea1c snapshot: new XML for external system checkpoint
Each <domainsnapshot> can now contain an optional <memory>
element that describes how the VM state was handled, similar
to disk snapshots.  The new element will always appear in
output; for back-compat, an input that lacks the element will
assume 'no' or 'internal' according to the domain state.

Along with this change, it is now possible to pass <disks> in
the XML for an offline snapshot; this also needs to be wired up
in a future patch, to make it possible to choose internal vs.
external on a per-disk basis for each disk in an offline domain.
At that point, using the --disk-only flag for an offline domain
will be able to work.

For some examples below, remember that qemu supports the
following snapshot actions:

qemu-img: offline external and internal disk
savevm: online internal VM and disk
migrate: online external VM
transaction: online external disk

=====
<domainsnapshot>
  <memory snapshot='no'/>
  ...
</domainsnapshot>

implies that there is no VM state saved (mandatory for
offline and disk-only snapshots, not possible otherwise);
using qemu-img for offline domains and transaction for online.

=====
<domainsnapshot>
  <memory snapshot='internal'/>
  ...
</domainsnapshot>

state is saved inside one of the disks (as in qemu's 'savevm'
system checkpoint implementation).  If needed in the future,
we can also add an attribute pointing out _which_ disk saved
the internal state; maybe disk='vda'.

=====
<domainsnapshot>
  <memory snapshot='external' file='/path/to/state'/>
  ...
</domainsnapshot>

This is not wired up yet, but future patches will allow this to
control a combination of 'virsh save /path/to/state' plus disk
snapshots from the same point in time.

=====

So for 1.0.1 (and later, as needed), I plan to implement this table
of combinations, with '*' designating new code and '+' designating
existing code reached through new combinations of xml and/or the
existing DISK_ONLY flag:

domain  memory  disk   disk-only | result
-----------------------------------------
offline omit    omit   any       | memory=no disk=int, via qemu-img
offline no      omit   any       |+memory=no disk=int, via qemu-img
offline omit/no no     any       | invalid combination (nothing to snapshot)
offline omit/no int    any       |+memory=no disk=int, via qemu-img
offline omit/no ext    any       |*memory=no disk=ext, via qemu-img
offline int/ext any    any       | invalid combination (no memory to save)
online  omit    omit   off       | memory=int disk=int, via savevm
online  omit    omit   on        | memory=no disk=default, via transaction
online  omit    no/ext off       | unsupported for now
online  omit    no     on        | invalid combination (nothing to snapshot)

a3e95abeb5 Document bracket whitespace rules & add syntax-check rule
This documents the following whitespace rules

      if(foo)   // Bad
      if (foo)  // Good

      int foo (int wizz)  // Bad
      int foo(int wizz)   // Good

      bar = foo (wizz);  // Bad
      bar = foo(wizz);   // Good

      typedef int (*foo) (int wizz);  // Bad
      typedef int (*foo)(int wizz);   // Good

      int foo( int wizz );  // Bad
      int foo(int wizz);    // Good

There is a syntax-check rule extension to validate all these rules.
Checking for 'function (...args...)' is quite difficult since it
needs to ignore valid usage with keywords like 'if (...test...)'
and while/for/switch. It must also ignore source comments and
quoted strings.

It is not possible todo this with a simple regex in the normal
syntax-check style. So a short Perl script is created instead
to analyse the source. In practice this works well enough. The
only thing it can't cope with is multi-line quoted strings of
the form

 "start of string\
more lines\
more line\
the end"

but this can and should be written as

 "start of string"
 "more lines"
 "more line"
 "the end"

with this simple change, the bracket checking script does not
have any false positives across libvirt source, provided it
is only run against .c files. It is not practical to run it
against .h files, since those use whitespace extensively to
get alignment (though this is somewhat inconsistent and could
arguably be fixed).

The only limitation is that it cannot detect a violation where
the first arg starts with a '*', eg

   foo(*wizz);

since this generates too many false positives on function
typedefs which can't be supressed efficiently.

fe772f24a6 daemon: Avoid 'Could not find keytab file' in syslog
On F17 at least, every time libvirtd starts we get this in syslog:

libvirtd: Could not find keytab file: /etc/libvirt/krb5.tab: No such file or directory

This comes from cyrus-sasl, and happens regardless of whether the
gssapi plugin is requested, which is what actually uses
/etc/libvirt/krb5.tab.

While cyrus-sasl shouldn't complain, we can easily make it shut up by
commenting out the keytab value by default.

Also update the keytab comment to the more modern one from qemu's
sasl config file.

e2c41e4860 storage: match RNG to supported driver types
At one point, the code passed through arbitrary strings for file
formats, which supposedly lets qemu handle a new file type even
before libvirt has been taught to handle it.  However, to properly
label files, libvirt has to learn the file type anyway, so we
might as well make our life easier by only accepting file types
that we are prepared to handle.  This patch lets the RNG validation
ensure that only known strings are let through.

f108944ae0 doc: Sort out the relationship between <vcpu>, <vcpupin>, and <emulatorpin>
These 3 elements conflicts with each other in either the doc
or the underlying codes.

Current problems:

Problem 1:

The doc shouldn't simply say "These settings are superseded
by CPU tuning. " for element <vcpu>. As except the tuning, <vcpu>
allows to specify the current, maxmum vcpu number. Apart from that,
<vcpu> also allows to specify the placement as "auto", which binds
the domain process to the advisory nodeset from numad.

Problem 2:

Doc for <vcpu> says its "cpuset" specify the physical CPUs
that the vcpus can be pinned. But it's not the truth, as
actually it only pin domain process to the specified physical
CPUs. So either it's a document bug, or code bug.

Problem 3:

Doc for <vcpupin> says it supersed "cpuset" of <vcpu>, it's
not quite correct, as each <vcpupin> specify the pinning policy
only for one vcpu. How about the ones which doesn't have
<vcpupin> specified? it says the vcpu will be pinned to all
available physical CPUs, but what's the meaning of attribute
"cpuset" of <vcpu> then?

Problem 4:

Doc for <emulatorpin> says it pin the emulator threads (domain
process in other context, perhaps another follow up patch to
cleanup the inconsistency is needed) to the physical CPUs
specified its attribute "cpuset". Which conflicts with
<vcpu>'s "cpuset". And actually in the underlying codes,
it set the affinity for domain process twice if both
"cpuset" for <vcpu> and <emulatorpin> are specified,
and <emulatorpin>'s pinning will override <vcpu>'s.

Problem 5:

When "placement" of <vcpu> is "auto" (I.e. uses numad to
get the advisory nodeset to which the domain process is
pinned to), it will also be overridden by <emulatorpin>,

This patch is trying to sort out the conflicts or bugs by:

1) Don't say <vcpu> is superseded by <cputune>

2) Keep the semanteme for "cpuset" of <vcpu> (I.e. Still says it
   specify the physical CPUs the virtual CPUs). But modifying it
   to mention it also set the pinning policy for domain process,
   and the CPU placement of domain process specified by "cpuset"
   of <vcpu> will be ingored if <emulatorpin> specified, and
   similary, the CPU placement of vcpu thread will be ignored
   if it has <vcpupin> specified, for vcpu which doesn't have
   <vcpupin> specified, it inherits "cpuset" of <vcpu>.

3) Don't say <vcpu> is supersed by <vcpupin>. If neither <vcpupin>
   nor "cpuset" of <vcpu> is specified, the vcpu will be pinned
   to all available pCPUs.

4) If neither <emulatorpin> nor "cpuset" of <vcpu> is specified,
   the domain process (emulator threads in the context) will be
   pinned to all available pCPUs.

5) If "placement" of <vcpu> is "auto", <emulatorpin> is not allowed.

6) hotplugged vcpus will also inherit "cpuset" of <vcpu>

Codes changes according to above document changes:

1) Inherit def->cpumask for each vcpu which doesn't have <vcpupin>
   specified, during parsing.

2) ping the vcpu which doesn't have <vcpupin> specified to def->cpumask
   either by cgroup for sched_setaffinity(2), which is actually done
   by 1).

3) Error out if "placement" == "auto", and <emulatorpin> is specified.
   Otherwise, <emulatorpin> is honored, and "cpuset" of <cpuset> is
   ignored.

4) Setup cgroup for each hotplugged vcpu, and setup the pinning policy
   by either cgroup or sched_setaffinity(2).

5) Remove cgroup and <vcpupin> for each hot unplugged vcpu.

Patches are following (6 in total except this patch)

893647671b locking: Implement lock failure action in sanlock driver
While the changes to sanlock driver should be stable, the actual
implementation of sanlock_helper is supposed to be replaced in the
future. However, before we can implement a better sanlock_helper, we
need an administrative interface to libvirtd so that the helper can just
pass a "leases lost" event to the particular libvirt driver and
everything else will be taken care of internally. This approach will
also allow libvirt to pass such event to applications and use
appropriate reasons when changing domain states.

The temporary implementation handles all actions directly by calling
appropriate libvirt APIs (which among other things means that it needs
to know the credentials required to connect to libvirtd).

5090c576e3 Add a ./run script for running programs from the local directory.
With this script you can run libvirt programs without needing to

  ./run ./tools/virsh [args ...]

If you are already in the tools/ subdirectory, then the following
command will also work:

  ../run ./virsh [...]

You can also run the C programs under valgrind like this:

  ./run valgrind [valgrind opts...] ./program

or under gdb:

  ./run gdb --args ./program

This also works with sudo (eg. if you need root access for libvirt):

  sudo ./run ./tools/virsh list --all

Derived from libguestfs and simplified.  The ./run script in
libguestfs is much more sophisticated:

ef1e024df8 blockjob: add virDomainBlockCommit
A block commit moves data in the opposite direction of block pull.
Block pull reduces the chain length by dropping backing files after
data has been pulled into the top overlay, and is always safe; block
commit reduces the chain length by dropping overlays after data has
been committed into the backing file, and any files that depended
on base but not on top are invalidated at any point where they have
unallocated data that is now pointing to changed contents in base.
Both directions are useful, however: a qcow2 layer that is more than
50% allocated will typically be faster with a pull operation, while
a qcow2 layer with less than 50% allocation will be faster as a
commit operation.  Committing across multiple layers can be more
efficient than repeatedly committing one layer at a time, but
requires extra support from the hypervisor.

This API matches Jeff Cody's proposed qemu command 'block-commit':
https://lists.gnu.org/archive/html/qemu-devel/2012-09/msg02226.html

Jeff's command is still in the works for qemu 1.3, and may gain
further enhancements, such as the ability to control on-error
handling (it will be comparable to the error handling Paolo is
adding to 'drive-mirror', so a similar solution will be needed
when I finally propose virDomainBlockCopy with more functionality
than the basics supported by virDomainBlockRebase).  However, even
without qemu support, this API will be useful for _offline_ block
commits, by wrapping qemu-img calls and turning them into a block
job, so this API is worth committing now.

For some examples of how this will be implemented, all starting
with the chain: base <- snap1 <- snap2 <- active

+ These are equivalent:
 virDomainBlockCommit(dom, disk, NULL, NULL, 0, 0)
 virDomainBlockCommit(dom, disk, NULL, "active", 0, 0)
 virDomainBlockCommit(dom, disk, "base", NULL, 0, 0)
 virDomainBlockCommit(dom, disk, "base", "active", 0, 0)
but cannot be implemented for online qemu with round 1 of
Jeff's patches; and for offline images, it would require
three back-to-back qemu-img invocations unless qemu-img
is patched to allow more efficient multi-layer commits;
the end result would be 'base' as the active disk with
contents from all three other files, where 'snap1' and
'snap2' are invalid right away, and 'active' is invalid
once any further changes to 'base' are made.

+ These are equivalent:
 virDomainBlockCommit(dom, disk, "snap2", NULL, 0, 0)
 virDomainBlockCommit(dom, disk, NULL, NULL, 0, _SHALLOW)
they cannot be implemented for online qemu, but for offline,
it is a matter of 'qemu-img commit active', so that 'snap2'
is now the active disk with contents formerly in 'active'.

+ Similarly:
 virDomainBlockCommit(dom, disk, "snap2", NULL, 0, _DELETE)
for an offline domain will merge 'active' into 'snap2', then
delete 'active' to avoid leaving a potentially invalid file
around.

+ This version:
 virDomainBlockCommit(dom, disk, NULL, "snap2", 0, _SHALLOW)
can be implemented online with 'block-commit' passing a base of
snap1 and a top of snap2; and can be implemented offline by
'qemu-img commit snap2' followed by 'qemu-img rebase -u
-b snap1 active'

3f9274a524 conf: add <vlan> element to network and domain interface elements
The following config elements now support a <vlan> subelements:

within a domain: <interface>, and the <actual> subelement of <interface>
within a network: the toplevel, as well as any <portgroup>

Each vlan element must have one or more <tag id='n'/> subelements.  If
there is more than one tag, it is assumed that vlan trunking is being
requested. If trunking is required with only a single tag, the
attribute "trunk='yes'" should be added to the toplevel <vlan>
element.

Some examples:

  <interface type='hostdev'/>
    <vlan>
      <tag id='42'/>
    </vlan>
    <mac address='52:54:00:12:34:56'/>
    ...
  </interface>

  <network>
    <name>vlan-net</name>
    <vlan trunk='yes'>
      <tag id='30'/>
    </vlan>
    <virtualport type='openvswitch'/>
  </network>

  <interface type='network'/>
    <source network='vlan-net'/>
    ...
  </interface>

  <network>
    <name>trunk-vlan</name>
    <vlan>
      <tag id='42'/>
      <tag id='43'/>
    </vlan>
    ...
  </network>

  <network>
    <name>multi</name>
    ...
    <portgroup name='production'/>
      <vlan>
        <tag id='42'/>
      </vlan>
    </portgroup>
    <portgroup name='test'/>
      <vlan>
        <tag id='666'/>
      </vlan>
    </portgroup>
  </network>

  <interface type='network'/>
    <source network='multi' portgroup='test'/>
    ...
  </interface>

IMPORTANT NOTE: As of this patch there is no backend support for the
vlan element for *any* network device type. When support is added in
later patches, it will only be for those select network types that
support setting up a vlan on the host side, without the guest's
involvement. (For example, it will be possible to configure a vlan for
a guest connected to an openvswitch bridge, but it won't be possible
to do that for one that is connected to a standard Linux host bridge.)

6a3691b743 network: merge relevant virtualports rather than choosing one
One of the original ideas behind allowing a <virtualport> in an
interface definition as well as in the <network> definition *and*one
or more <portgroup>s within the network, was that guest-specific
parameteres (like instanceid and interfaceid) could be given in the
interface's virtualport, and more general things (portid, managerid,
etc) could be given in the network and/or portgroup, with all the bits
brought together at guest startup time and combined into a single
virtualport to be used by the guest. This was somehow overlooked in
the implementation, though - it simply picks the "most specific"
virtualport, and uses the entire thing, with no attempt to merge in
details from the others.

This patch uses virNetDevVPortProfileMerge3() to combine the three
possible virtualports into one, then uses
virNetDevVPortProfileCheck*() to verify that the resulting virtualport
type is appropriate for the type of network, and that all the required
attributes for that type are present.

An example of usage is this: assuming a <network> definitions on host
ABC of:

  <network>
    <name>testA</name>
    ...
    <virtualport type='openvswitch'/>
    ...
    <portgroup name='engineering'>
      <virtualport>
        <parameters profileid='eng'/>
      </virtualport>
    </portgroup>
    <portgroup name='sales'>
      <virtualport>
        <parameters profileid='sales'/>
      </virtualport>
    </portgroup>
  </network>

and the same <network> on host DEF of:

  <network>
    <name>testA</name>
    ...
    <virtualport type='802.1Qbg'>
      <parameters typeid="1193047" typeidversion="2"/>
    </virtualport>
    ...
    <portgroup name='engineering'>
      <virtualport>
        <parameters managerid="11"/>
      </virtualport>
    </portgroup>
    <portgroup name='sales'>
      <virtualport>
        <parameters managerid="55"/>
      </virtualport>
    </portgroup>
  </network>

and a guest <interface> definition of:

  <interface type='network'>
    <source network='testA' portgroup='sales'/>
    <virtualport>
      <parameters instanceid="09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f"
                  interfaceid="09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f"\>
    </virtualport>
    ...
  </interface>

If the guest was started on host ABC, the <virtualport> used would be:

  <virtualport type='openvswitch'>
    <parameters interfaceid='09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f'
                profileid='sales'/>
  </virtualport>

but if that guest was started on host DEF, the <virtualport> would be:

    <virtualport type='802.1Qbg'>
      <parameters instanceid="09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f"

                  managerid="55"/>
    </virtualport>

(this includes cases where no virtualport is given at all),

4af3cbafdd conf: support partially-specified <virtualport> in parser and formatter
Until now, all attributes in a <virtualport> parameter list that were
acceptable for a particular type, were also required. There were no
optional attributes.

One of the aims of supporting <virtualport> in libvirt's virtual
networks and portgroups is to allow specifying the group-wide
parameters in the network's virtualport, and merge that with the
interface's virtualport, which will have the instance-specific info
(i.e. the interfaceid or instanceid).

Additionally, the guest's interface XML shouldn't need to know what
type of network connection will be used prior to runtime - it could be
openvswitch, 802.1Qbh, 802.1Qbg, or none of the above - but should
still be able to specify instance-specific info just in case it turns
out to be applicable.

Finally, up to now, the parser for virtualport has always generated a
random instanceid/interfaceid when appropriate, making it impossible
to leave it blank (which is what's required for virtualports within a
network/portprofile definition).

This patch modifies the parser and formatter of the <virtualport>
element in the following ways:

* because most of the attributes in a virNetDevVPortProfile are fixed
  size binary data with no reserved values, there is no way to embed a
  "this value wasn't specified" sentinel into the existing data. To
  solve this problem, the new *_specified fields in the
  virNetDevVPortProfile object that were added in a previous patch of
  this series are now set when the corresponding attribute is present
  during the parse.

* allow parsing/formatting a <virtualport> that has no type set. In
  this case, all fields are settable, but all are also optional.

* add a GENERATE_MISSING_DEFAULTS flag to the parser - if this flag is
  set and an instanceid/interfaceid is expected but not provided, a
  random one will be generated. This was previously the default
  behavior, but is now done only for virtualports inside an
  <interface> definition, not for those in <network> or <portgroup>.

* add a REQUIRE_ALL_ATTRIBUTES flag to the parser - if this flag is
  set the parser will call the new
  virNetDevVPortProfileCheckComplete() functions at the end of the
  parser to check for any missing attributes (based on type), and
  return failure if anything is missing. This used to be default
  behavior. Now it is only used for the virtualport defined inside an
  interface's <actual> element (by the time you've figured out the
  contents of <actual>, you should have all the necessary data to fill
  in the entire virtualport)

* add a REQUIRE_TYPE flag to the parser - if this flag is set, the
  parser will return an error if the virtualport has no type
  attribute. This also was previously the default behavior, but isn't
  needed in the case of the virtualport for a type='network' interface
  (i.e. the exact type isn't yet known), or the virtualport of a
  portgroup (i.e. the portgroup just has modifiers for the network's
  virtualport, which *does* require a type) - in those cases, the
  check will be done at domain startup, once the final virtualport is
  assembled (this is handled in the next patch).

0925189713 domain_conf: Add USB controler model "none"
Libvirt adds a USB controller to the guest even if the user does not
specify any in the XML. This is due to back-compat reasons.

To allow disabling USB for a guest this patch adds a new USB controller
type "none" that disables USB support for the guest.

5e21da5630 build: regenerate .png files
We don't expect people to have tools installed to regenerate .png
from .fig by default.  However, since commit 5eb3df8, several
.fig files were updated without regenerating the .png file, and
as a result, 'make dist' ends up regenerating those five files,
or worse, failing because of missing tools (convert from
ImageMagick).

Additionally, even if the tools are present, the generation of
.png files is nondeterministic (the resulting files contain a
timestamp), which means prior to this patch, running 'make dist'
from two checkouts will end up producing different tarball
contents (two 'make dist' runs will always produce different tar
files, since tarballs also contain timestamps; but unpacking the
tarballs and doing a recursive diff will show if the contents
are unchanged).

After this patch, the timestamps are now up-to-date, and 'make
dist' no longer has anything to do for the .png files.  This gets
us closer to the goal of two checkouts being able to produce the
same tarball.

* docs/libvirt-*.png: Regenerate.

d57e17d583 doc: Fix time keeping example for the guest clock
The time keeping example was missing quotes which resulted in an error
if you copied and pasted the example into a domain's XML. Additionally
the rest of the examples use single quotes (') instead of double quotes
(") so standardized that.

29bc4fe646 Add a sheepdog backend for the storage driver
This patch brings support to manage sheepdog pools and volumes to libvirt.
It uses the "collie" command-line utility that comes with sheepdog for that.

A sheepdog pool in libvirt maps to a sheepdog cluster.
It needs a host and port to connect to, which in most cases
is just going to be the default of localhost on port 7000.

A sheepdog volume in libvirt maps to a sheepdog vdi.
To create one specify the pool, a name and the capacity.
Volumes can also be resized later.

In the volume XML the vdi name has to be put into the <target><path>.
To use the volume as a disk source for virtual machines specify
the vdi name as "name" attribute of the <source>.
The host and port information from the pool are specified inside the host tag.

  <disk type='network'>
    ...
    <source protocol="sheepdog" name="vdi_name">
      <host name="localhost" port="7000"/>
    </source>
  </disk>

To work right this patch parses the output of collie,
so it relies on the raw output option. There recently was a bug which caused
size information to be reported wrong. This is fixed upstream already and
will be in the next release.

Currently you can configure LXC to bind a host directory to

this itself, allowing it in the libvirt XML means a stricter

b34324fbf0 schema: Update domain XML schema
'boot' tag shouldn't be exclusive with 'kernel', 'initrd', and 'cmdline',
though the boot sequence doesn't make sense when the guest boots from
kernel directly. But it's useful if booting from kernel is to install
a newguest, even if it's not to install a guest, there is no hurt. And
on the other hand, we allow 'boot' and the kernel tags when parsing.
