b59bb93129 Make LXC work with new network configuration types
If using one of the new non-NAT/routed virtual network
configurations, the LXC driver would not know how to
setup the VETH devices. Adding in calls to setup the
"actual" network configuration at VM startup and cleanup
when shutting down fixes this.

29879b550b snapshot: enforce REVERT_FORCE on qemu
Implements the documentation for snapshot revert vs. force.

Part of the patch tightens existing behavior (previously, reverting
to an old snapshot without <domain> was blindly attempted, now it
requires force), while part of it relaxes behavior (previously, it
was not possible to revert an active domain to an ABI-incompatible
active snapshot, now force allows this transition).

risky situations, and allow force to get past them.

70e015e12f snapshot: use qemu-img on disks in use at time of snapshot

3c797404a5 snapshot: add REVERT_FORCE to API
Although reverting to a snapshot is a form of data loss, this is
normally expected.  However, there are two cases where additional
surprises (failure to run the reverted state, or a break in
connectivity to the domain) can come into play.  Requiring extra
acknowledgment in these cases will make it less likely that
someone can get into an unrecoverable state due to a default revert.

Also create a new error code, so users can distinguish when forcing
would make a difference, rather than having to blindly request force.

New flag.

869b69ea3d snapshot: implement snapshot roots listing in vbox
Commit 9f5e53e introduced the ability to filter snapshots to
just roots, but it was never implemented for VBox until now.

The VBox implementation prohibits deletion of a snapshot with
multiple children.  Hence, there can only be at most one root,
which is found by searching for the snapshot with a NULL uuid.

Prior to 4.0, snapshotGet looked up by UUID, and snapshotFind
looked up by name; after that point, snapshotGet disappeared
and snapshotFind handles uuid or name.

(vboxDomainSnapshotListNames): Implement limiting list to root.

fcd2bd55d7 qemu: Don't fail virDomainGetInfo if we can't update balloon info
Qemu driver tries to update balloon data in virDomainGetInfo and if it
can't do so because there is another monitor job running, it just
reports what's known in domain def. However, if there was no job running
but getting the data from qemu fails, we would fail the whole API. This
doesn't make sense. Let's make the failure nonfatal.

12062abb89 qemu: correct misspelled 'enospc' option, and only use for werror
This resolves:

     https://bugzilla.redhat.com/show_bug.cgi?id=730909

When support for setting the qemu disk error policy to "enospc" was
added, it was inadvertently spelled "enospace". This patch corrects
that on the qemu commandline (while retaining the "enospace" spelling
for libvirt's XML).

Also, while examining the qemu source, I found that "enospc" is not
allowed for the read error policy, only for write error policy (makes
sense). Since libvirt currently only has a single error policy
setting, when "enospace" is selected, the read error policy is set to
"ignore".

652f887144 Allow passing of command line args to LXC container
When booting a virtual machine with a kernel/initrd it is possible
to pass command line arguments using the <cmdline>...args...</cmdline>
element in the guest XML. These appear to the kernel / init process
in /proc/cmdline.

When booting a container we do not have a custom /proc/cmdline,
but we can easily set an environment variable for it. Ideally
we could pass individual arguments to the init process as a
regular set of 'char *argv[]' parameters, but that would involve
libvirt parsing the <cmdline> XML text. This can easily be added
later, even if we add the env variable now

6c9e2eb23b network: fill in bandwidth from portgroup for all forward modes
This patch is a fix for:

  https://bugzilla.redhat.com/show_bug.cgi?id=743176

which was discovered by Dan Berrange while making bandwidth
configuration work for LXC guests.

Background: Although virtportprofile data from a network portgroup is
only applicable for direct mode interfaces, the code that copies
bandwidth data from the portgroup was also only being executed in the
case of direct mode interfaces. The result was that interfaces using
traditional virtual networks (forward mode='nat|route|none'), and
those using a host bridge for forwarding, would not pick up bandwidth
data from a portgroup defined in the network.

This patch moves that code outside the conditional, so that bandwidth
information is *alway* copied from the appropriate portgroup (unless
the <interface> definition itself already has bandwidth information,
which would take precedence over what's in the portgroup anyway).

c329db7180 qemu: make PCI multifunction support more manual
When support for was added for PCI multifunction cards (in commit
9f8baf, first included in libvirt 0.9.3), it was done by always
turning on the multifunction bit for all PCI devices. Since that time
it has been realized that this is not an ideal solution, and that the
multifunction bit must be selectively turned on. For example, see

  https://bugzilla.redhat.com/show_bug.cgi?id=728174

and the discussion before and after

  https://www.redhat.com/archives/libvir-list/2011-September/msg01036.html

This patch modifies multifunction support so that the multifunction=on
option is only added to the qemu commandline for a device if its PCI
<address> definition has the attribute "multifunction='on'", e.g.:

  <address type='pci' domain='0x0000' bus='0x00'
           slot='0x04' function='0x0' multifunction='on'/>

In practice, the multifunction bit should only be turned on if
function='0' AND other functions will be used in the same slot - it
usually isn't needed for functions 1-7 (although there are apparently
some exceptions, e.g. the Intel X53 according to the QEMU source
code), and should never be set if only function 0 will be used in the
slot. The test cases have been changed accordingly to illustrate.

With this patch in place, if a user attempts to assign multiple
functions in a slot without setting the multifunction bit for function
0, libvirt will issue an error when the domain is defined, and the
define operation will fail. In the future, we may decide to detect
this situation and automatically add multifunction=on to avoid the
error; even then it will still be useful to have a manual method of
turning on multifunction since, as stated above, there are some
devices that excpect it to be turned on for all functions in a slot.

A side effect of this patch is that attempts to use the same PCI
address for two different devices will now log an error (previously
this would cause the domain define operation to fail, but there would
be no log message generated). Because the function doing this log was
almost completely rewritten, I didn't think it worthwhile to make a
separate patch for that fix (the entire patch would immediately be
obsoleted).

30f555c6a8 lvm storage backend: handle command_names=1 in lvm.conf
If the regexes supported (?:pvs)?, then we could handle this by
optionally matching but not returning the initial command name.  But it
doesn't.  So add a new char* argument to
virStorageBackendRunProgRegex().  If that argument is NULL then we act
as usual.  Otherwise, if the string at that argument is found at the
start of a returned line, we drop that before running the regex.

With this patch, virt-manager shows me lvs with command_names 1 or 0.

The definitions of PVS_BASE etc may want to be moved into the configure
scripts (though given how PVS is found, IIUC that could only happen if
pvs was a link to pvs_real), but in any case no sense dealing with that
until we're sure this is an ok way to handle it.

46e8dc710a security: properly chown/label bidirectional and unidirectional fifos
This patch fixes the regression with using named pipes for qemu serial
devices noted in:

  https://bugzilla.redhat.com/show_bug.cgi?id=740478

The problem was that, while new code in libvirt looks for a single
bidirectional fifo of the name given in the config, then relabels that
and continues without looking for / relabelling the two unidirectional
fifos named ${name}.in and ${name}.out, qemu looks in the opposite
order. So if the user had naively created all three fifos, libvirt
would relabel the bidirectional fifo to allow qemu access, but qemu
would attempt to use the two unidirectional fifos and fail (because it
didn't have proper permissions/rights).

This patch changes the order that libvirt looks for the fifos to match
what qemu does - first it looks for the dual fifos, then it looks for
the single bidirectional fifo. If it finds the dual unidirectional
fifos first, it labels/chowns them and ignores any possible
bidirectional fifo.

(Note commit d37c6a3a (which first appeared in libvirt-0.9.2) added
the code that checked for a bidirectional fifo. Prior to that commit,
bidirectional fifos for serial devices didn't work because libvirt
always required the ${name}.(in|out) fifos to exist, and qemu would
always prefer those.

dc79852af8 qemu: add ability to set PCI device "rombar" on or off
This patch was made in response to:

  https://bugzilla.redhat.com/show_bug.cgi?id=738095

In short, qemu's default for the rombar setting (which makes the
firmware ROM of a PCI device visible/not on the guest) was previously
0 (not visible), but they recently changed the default to 1
(visible). Unfortunately, there are some PCI devices that fail in the
guest when rombar is 1, so the setting must be exposed in libvirt to
prevent a regression in behavior (it will still require explicitly
setting <rom bar='off'/> in the guest XML).

rombar is forced on/off by adding:

  <rom bar='on|off'/>

inside a <hostdev> element that defines a PCI device. It is currently
ignored for all other types of devices.

At the moment there is no clean method to determine whether or not the
rombar option is supported by QEMU - this patch uses the advice of a
QEMU developer to assume support for qemu-0.12+. There is currently a
patch in the works to put this information in the output of "qemu-kvm
-device pci-assign,?", but of course if we switch to keying off that,
we would lose support for setting rombar on all the versions of qemu
between 0.12 and whatever version gets that patch.

SIGTERM handling for -no-shutdown is already fixed in qemu git and
libvirt can safely use it. The downside is that 0.15.50 version of qemu
can be any qemu compiled from git, even that without the fix for
SIGTERM. However, I think this patch is worth it since excluding 0.15.50
from the check makes testing current qemu with libvirt much easier and
someone running qemu from git should be able to rebuild fixed qemu from
git if they hit the problem with a hang on shutdown.

The problem is that sometimes there are dummy calls from a
virStreamRecv() call waiting that *do* need to be notified.

These dummy calls should have a status VIR_NET_CONTINUE. So
re-add the notification upon VIR_NET_CONTINUE, but only if
the waiter also has a status of VIR_NET_CONTINUE.

* src/rpc/virnetclient.c: Notify waiting call if stream data
  arrives
* src/rpc/virnetclientstream.c:  Mark dummy stream read packet
  with status VIR_NET_CONTINUE

1888363d8b selinux: Correctly report warning if virt_use_nfs not set
Previous patch c9b37fee tried to deal with virt_use_nfs. But
setfilecon() returns EOPNOTSUPP on NFS so we need to move the
warning to else branch.

c42e1c3947 qemu: Transfer inactive XML among cookie
If a domain has inactive XML we want to transfer it to destination
when migrating with VIR_MIGRATE_PERSIST_DEST. In order to harm
the migration protocol as least as possible, a optional cookie was
chosen.

61dbee0efd snapshot: also delete empty directory
The previous patch removed all snapshots, but not the directory
where the snapshots lived, which is still a form of stale data.

* src/qemu/qemu_domain.c (qemuDomainRemoveInactive): Wipe any
snapshot directory.
