95ff6b18ec Set sensible defaults for cpu match and feature policy
To enable the CPU XML from the capabilities to be pasted directly
into the guest XML with no editing, pick a sensible default for
match and feature policy. The CPU match will be exact and the
feature policy will be require. This should ensure safety for
migration and give DWIM semantics for users

* src/conf/cpu_conf.c: Default to exact match and require policy
* docs/formatdomain.html.in: Document new defaults

093973aabe xen: Fix virDomain{At,De}tachDevice
According to API documentation virDomain{At,De}tachDevice calls are
supposed to only work on active guests for device hotplug. For anything
beyond that, their *Flags variants have to be used.

Despite the variant which was acked on libvirt mailing list
(https://www.redhat.com/archives/libvir-list/2010-January/msg00385.html)
commit ed9c14a7ef (by Jim Fehlig)
introduced automagic behavior of these API calls for xen driver. Since
January, these calls always change persistent configuration of a guest
and if the guest is currently active, they also hot(un)plug the device.

That change didn't follow API documentation and also broke device
hot(un)plug for older xend implementations which do not support changing
persistent configuration of a guest and hot(un)plugging in one step.

This patch should not break anything for active guests. On the other
hand, changing inactive guests is not supported any more.

28160e2264 xen: Make xenDaemon*DeviceFlags errors less confusing
When a user calls to virDomain{Attach,Detach,Update}DeviceFlags() with
flags == VIR_DOMAIN_DEVICE_MODIFY_LIVE on an inactive guest running on
an old Xen hypervisor (such as RHEL-5) xend_internal driver reports:

    Xend version does not support modifying persistent config

which is pretty confusing since no-one requested to modify persistent
config.

5b0c71ee07 nwfilter: Instantiate state match in ip(6)tables rules
In this patch I am extending the rule instantiator to create the state
match according to the state attribute in the XML. Only one iptables
rule in the incoming or outgoing direction will be created for a rule
in direction 'in' or 'out' respectively. A rule in direction 'inout' does
get iptables rules in both directions.

593e0072eb implement usb and pci hot attach in AppArmor driver
Description: Implement AppArmorSetSecurityHostdevLabel() and
AppArmorRestoreSecurityHostdevLabel() for hostdev and pcidev attach.

virt-aa-helper also has to be adjusted because *FileIterate() is used for pci
and usb devices and the corresponding XML for hot attached hostdev and pcidev
is not in the XML passed to virt-aa-helper. The new '-F filename' option is
added to append a rule to the profile as opposed to the existing '-f
filename', which rewrites the libvirt-<uuid>.files file anew. This new '-F'
option will append a rule to an existing libvirt-<uuid>.files if it exists,
otherwise it acts the same as '-f'.

load_profile() and reload_profile() have been adjusted to add an 'append'
argument, which when true will use '-F' instead of '-f' when executing
virt-aa-helper.

All existing calls to load_profile() and reload_profile() have been adjusted
to use the old behavior (ie append==false) except AppArmorSetSavedStateLabel()
where it made sense to use the new behavior.

This patch also adds tests for '-F'.

b00f41a1d2 nwfilter: Instantiate comments in ip(6)tables rules
In this patch I am extending the rule instantiator to create the comment
node where supported, which is the case for iptables and ip6tables.

Since commands are written in the format

cmd='iptables ...-m comment --comment \"\" '

certain characters ('`) in the comment need to be escaped to
prevent comments from becoming commands themselves or cause other
forms of (bash) substitutions. I have tested this with various input and in
my tests the input made it straight into the comment. A test case for TCK
will be provided separately that tests this.

18af6f4e64 buf: Fix possible infinite loop in EscapeString, VSnprintf
The current code will go into an infinite loop if the printf generated
string is >= 1000, AND exactly 1 character smaller than the amount of free
space in the buffer. When this happens, we are dropped into the loop body,
but nothing will actually change, because count == (buf->size - buf->use - 1),
and virBufferGrow returns unchanged if count < (buf->size - buf->use)

Fix this by removing the '- 1' bit from 'size'. The *nprintf functions handle
the NULL byte for us anyways, so we shouldn't need to manually accommodate
for it.

Here's a bug where we are actually hitting this issue:
https://bugzilla.redhat.com/show_bug.cgi?id=602772

v2: Eric's improvements: while -> if (), remove extra va_list variable,
    make sure we report buffer error if snprintf fails

v3: Add tests/virbuftest which reproduces the infinite loop before this
    patch, works correctly after

847689129c esx: Rework datastore path parsing and handling
Instead of splitting the path part of a datastore path into
directory and file name, keep this in one piece. An example:

  "[datastore] directory/file"

was split into this before:

  datastoreName = "datastore"
  directoryName = "directory"
  fileName = "file"

Now it's split into this:

  datastoreName = "datastore"
  directoryName = "directory"
  directoryAndFileName = "directory/file"

This simplifies code using esxUtil_ParseDatastorePath, because
directoryAndFileName is used more often than fileName. Also the
old approach expected the datastore path to reference an actual
file, but this isn't always correct, especially when listing
volumes. In that case esxUtil_ParseDatastorePath is used to parse
a path that references a directory. This fails for a vpx://
connection because the vCenter returns directory paths with a
trailing '/'. The new approach is robust against this and the
actual decision if the datastore path should reference a file or
a directory is up to the caller of esxUtil_ParseDatastorePath.

Update the tests accordingly.
