d3ede96d6f wireshark: s/proto_tree_add_text/proto_tree_add_item/
In the wireshark commit e2735ecfdd7a96c they dropped
proto_tree_add_text in favor of proto_tree_add_item. Adapt to
this change.

Moreover, the proto_tree_add_item API is around for ages and we
are already using it anyway. Therefore we don't need to change
required version of wireshark.

6dc0e4f171 Fix LSB requirements in service script and sync them
Commit b22344f328 mistakenly reordered
Default-* lines.  Thanks to that I noticed that we are very inconsistent
with our init scripts, so I took the liberty of synchronizing them,
updating them and making them all look shiny and new.  So apart from
fixing the LSB requirements, I also fixed the ordering, specified
runlevels and fix the link to the reference specification.

6e2770174e virt-host-validate-common: Print warning on missing IOMMU
No only coverity warns about this, but it kind of makes sense

don't have it, I know. But in that case we should print a message
that it's unknown whether platform has it or not.

3245e1783c Revert "admin: Rename virAdmConnect to virAdmDaemon"
Commmit df8192aa introduced admin related rename and some minor
(caused by automated approach, aka sed) and some more severe isues along with
it. First reason to revert is the inconsistency with libvirt library.
Although we deal with the daemon directly rather than with a specific
hypervisor, we still do have a connection. That being said, contributors might
get under the impression that AdmDaemonNew would spawn/start a new daemon
(since it's admin API, why not...), or AdmDaemonClose would do the exact
opposite or they might expect DaemonIsAlive report overall status of the daemon
which definitely isn't the case.
The second reason to revert this patch is renaming virt-admin client. The
client tool does not necessarily have to reflect the names of the API's it's
using in his internals. An example would be 's/vshAdmConnect/vshAdmDaemon'
where noone can be certain of what the latter function really does. The former
is quite expressive about some connection magic it performs, but the latter does
not say anything, especially when vshAdmReconnect and vshAdmDisconnect were
left untouched.

2eba5c5635 virsh: Add --delete-snapshots flag for undefine and vol-delete
https://bugzilla.redhat.com/show_bug.cgi?id=1281710

Commit id '3c7590e0a' added the flag to the rbd backend, but provided
no means via virsh to use the flag.  This patch adds a '--delete-snapshots'
option to both the "undefine" and "vol-delete" commands.

For "undefine", the flag is combined with the "--remove-all-storage" flag
in order to add the appropriate flag for the virStorageVolDelete call;
whereas, for the "vol-delete" command, just the flag is sufficient since
it's only operating on one volume.

Currently only supported for rbd backends.

e193735450 virsh: Add build flags to pool-create[-as] and pool-start
https://bugzilla.redhat.com/show_bug.cgi?id=830056

Utilize recently added VIR_STORAGE_POOL_CREATE_WITH_BUILD* flags in
order to pass the flags along to the virStoragePoolCreateXML and
virStoragePoolCreate API's.

This affects the 'virsh pool-create', 'virsh pool-create-as', and
'virsh pool-start' commands.  While it could be argued that pool-start
doesn't need the flags, they could prove useful for someone trying to
do one command build --overwrite and start command processing or
essentially starting with a clean slate.

NB:
This patch is loosely based upon code originally authored by Osier
Yang that were not reviewed and pushed, see:

df8192aaf4 admin: Rename virAdmConnect to virAdmDaemon
virAdmConnect was named after virConnect, but after some discussions,
most of the APIs called will be working with remote daemon and starting
them virAdmDaemon will make more sense.  Only possibly controversal name
is CloseCallback (de)registration, and connecting to the daemon (which
will still be Open/Close), but even this makes sense if one thinks about
the daemon being opened and closed, e.g. as file, etc.

This way all the APIs working with the daemon will start with
virAdmDaemon prefix, they will accept virAdmDaemonPtr as first parameter
and that will better suit with other namings as well (virDomain*,
virAdmServer*, etc.).

Because in virt-admin, the connection name does not refer to a struct
that would have a connect in its name, also adjust 'connname' in
clients.  And because it is not used anywhere in the vsh code, move it
from there into each client.

6dd7e42d89 admin: Add support for connection close callbacks
As we need a client disconnect handler, we also need a mechanism to register
such handlers for a client. This patch introduced both the close callbacks and
also the client vshAdmCatchDisconnect handler to be registered with it. By
registering the handler we still need to make sure the client can react to
daemon's events like disconnect or keepalive, so asynchronous I/O event polling
is necessary to be enabled too.

each number starting with 0 will be auto-detected as octal number and
that's wrong.  Another wrong use-case is for PCI address if for example
bus is 10, than it's incorrectly parsed as decimal number.

There might as well be other features that require re-initialization as
the command line could specify parameters that override our defaults which
had been set prior to calling vshArgvParse.

5c668a78d8 qemu: add udp interface support
Adds a new interface type using UDP sockets, this seems only applicable
to QEMU but have edited tree-wide to support the new interface type.

The interface type required the addition of a "localaddr" (local
address), this then maps into the following xml and qemu call.

<interface type='udp'>
  <mac address='52:54:00:5c:67:56'/>
  <source address='127.0.0.1' port='11112'>
    <local address='127.0.0.1' port='22222'/>
  </source>
  <model type='virtio'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
</interface>

QEMU call:
	-net socket,udp=127.0.0.1:11112,localaddr=127.0.0.1:22222

Notice the xml "local" entry becomes the "localaddr" for the qemu call.

70f56dd72c virsh: Reset global error after successfull domain lookup
When looking up a domain, we try to look up by ID, UUID and NAME
consequently while not really caring which of those lookups succeeds.
The problem is that if any of them fails, we dispatch the error from the
driver and that means setting both threadlocal and global error. Let's
say the last lookup (by NAME) succeeds and resets the threadlocal error as any
other API does, however leaving the global error unchanged. If the underlying
virsh command does not succeed afterwards, our cleanup routine in
vshCommandRun ensures that no libvirt error will be forgotten and that's
exactly where this global error comes in incorrectly.

 # virsh domif-setlink 123 vnet1 up
 error: interface (target: vnet1) not found
 error: Domain not found: no domain with matching id 123

This patch also resets the global error which would otherwise cause some
minor confusion in reported error messages.

834c5720e4 tools: Introduce new client generic module vsh
In order to share as much virsh' logic as possible with upcomming
virt-admin client we need to split virsh logic into virsh specific and
client generic features.

Since majority of virsh methods should be generic enough to be used by
other clients, it's much easier to rename virsh specific data to virshX
than doing this vice versa. It moved generic virsh commands (including info
and opts structures) to generic module vsh.c.

Besides renaming methods and structures, this patch also involves introduction
of a client specific control structure being referenced as private data in the
original control structure, introduction of a new global vsh Initializer,
which currently doesn't do much, but there is a potential for added
functionality in the future.
Lastly it introduced client hooks which are especially necessary during
client connecting phase.

Introduce helper function that will provide logic for waiting for block

This patch introduces the whole logic and uses it to fix
cmdBlockJobPull. The vshBlockJobWait function provides common logic for
block job waiting that should be robust enough to work across all
previous versions of libvirt. Since virsh allows passing user-provided
strings as paths of block devices we can't reliably use block job events
for detection of block job states so the function contains a great deal

f69ece073e virsh: Teach cmdFreepages to work with lxc driver
Some drivers don't expose available huge page sizes in the
capabilities XML. For instance, LXC driver is one of those.
This has a downside that when virsh is trying to get
aggregated info on free pages per all NUMA nodes, it fails.
The problem is that the virNodeGetFreePages() API expects
caller to pass an array of page sizes he is interested in.
In virsh, this array is filled from the capabilities from
'/capabilities/host/cpu/pages' XPath. As said, in LXC
there's no such XPath and therefore virsh fails currently.
But hey, we can fallback: the page sizes are exposed under
'/capabilities/host/topology/cells/cell/pages'. The page
size can be collected from there, and voilà the command
works again. But now we must make sure that there are no
duplicates in the array passed to the public API. Otherwise
we won't get as beautiful output as we are getting now.

a02a161bb8 qemu: libxl: vcpupin: Don't reset pinning when pinning to all pcpus
In the pre-NUMA ages pinning a vCPU to all pCPUs was eaqual to deleting
the pinning info. Now it does not entirely work that way. Pinning a vCPU
to all pCPUs might be a desired operation. Additionally removal of the
pinning will result into using the default pinning information at the
next boot which might be different from all vcpus.

This patch removes the false assumption that we should remove the
pinning after pinning to all vCPUs and tweaks the documentation for
virsh.

A later patch will implement a new flag for the virDomainPinVcpuFlags
API that will allow to remove the pinning in a sane way.

e9507fd41c virsh: Fix Ctrl-C behavior when watching a job
When watching a job (save, managedsave, dump, migrate) virsh spawns a
thread to call the appropriate API and waits for the result while
watching for interruption signals (SIGINT, Ctrl-C on the terminal).
Whenever such signal is caught, virsh calls virDomainAbortJob, stops
waiting for the job, and returns the result of virDomainAbortJob.

This is wrong because the job might have finished in the meantime or it
might have been cancelled by someone else and virsh would just report
the failure to abort the job. However, we are not interested in the
virDomainAbortJob's result at all, we need to keep waiting for the main
job to finish and report its result instead.

60107346a4 virsh: Report an error when cpulist parsing fails
When parsing a cpulist, the virBitmapParse is used. On an invalid
bitmap an error is reported, but the error gets cleared
immediately by subsequent public APIs call, e.g. virDomainFree().
Moreover, we don't check whether bitmap fits into maximal CPU ID
on the host. Therefore the following examples failed without any
error:

 # virsh vcpupin test3 1 aaa

 # virsh vcpupin test3 1 1000

Since 0fa15b19 we have this variable SYNC_TIME which allows users to

aa9f139599 migration: Usable time statistics without requiring NTP
virDomainGetJobStats is able to report statistics of a completed
migration, however to get usable downtime and total time statistics both
hosts have to keep synchronized time. To provide at least some
estimation of the times even when NTP daemons are not running on both
hosts we can just ignore the time needed to transfer a migration cookie
to the destination host. The result will be also inaccurate but a bit
more predictable. The total/down time will just be at least what we
report.

31ef0836a7 virsh: fix regression in 'virsh event' by domain
Commit a0670ae caused a regression in 'virsh event' and
'virsh qemu-monitor-event' - if a user tries to filter the
command to a specific domain, an error message is printed:

$ virsh event dom --loop
error: internal error: virsh qemu-monitor-event: no domain VSH_OT_DATA option

and then the command continues as though no domain had been
supplied (giving events for ALL domains, instead of the
requested one).  This is because the code was incorrectly
assuming that all "domain" options would be supplied via a
mandatory VSH_OT_DATA, even though "domain" is optional for
these two commands, so we had changed them to VSH_OT_STRING
to quit failing for other reasons (ever since it was decided
that VSH_OT_DATA and VSH_OT_STRING should no longer be
synonyms).

In looking at the situation, though, the code for looking up
a domain was making a pointless check for whether the option
exists prior to finding the option's string value, as
vshCommandOptStringReq does just fine at reporting any errors
when looking up a string whether or not the option was present.

So this is a case of regression fixing by pure code deletion :)

* tools/virsh-interface.c (vshCommandOptInterfaceBy): Likewise.

156fde0b1a virsh: Fix domifaddr output in quiet mode
In virsh we have two printing functions: vshPrint() which prints a
string onto stdout and vshPrintExtra() which does not print anything
if virsh is run in quiet mode. Usually, the former is used to print
actual results, while the latter to print strings like table headers
and other formatting stuff. However, in cmdDomIfAddr we have
mistakenly used vshPrintExtra even for actual data. After this patch,
the output should look like the following:

When libvirt is starting a domain, it reports the state as SHUTOFF until
it's RUNNING. This is not ideal because domain startup may take a long
time (usually because of some configuration issues, firewalls blocking
access to network disks, etc.) and domain lists provided by libvirt look
awkward. One can see weird shutoff domains with IDs in a list of active
domains or even shutoff transient domains. In any case, it looks more
like a bug in libvirt than a normal state a domain goes through.
