While debugging the support for responding to qemu RX_FILTER_CHANGED
events, I had changed the "ignoring this event" log message from
VIR_DEBUG to VIR_WARN, but forgot to change it back before
pushing. Since many guest OSes make enough changes to multicast lists
and/or promiscuous mode settings to trigger this message, it's
starting to show up as a red herring in bug reports.

Commit 5bba61f changed the XPath strings to be absolute when parsing

Use the relative string so that the <numa> settings are not lost.

Commit cf54c60699833b3791a5d0eb3eb5a1948c267f6b introduced the ability
to create missing storage volumes during migration. For network disks,
however, we may not necessarily be able to detect whether they already
exist -- there is no straight-forward way to map the disk to a storage
volume, and even if there were it's possible no configured storage pool
actually contains the disk.
It is better to assume the network disk exists in this case, rather than
aborting the migration completely. If the volume really is missing, QEMU
will generate an appropriate error later in the migration.

We interpret port values as signed int (convert them from char *),
so if a negative value is provided in network disk's configuration,
we accept it as valid, however there's an 'unknown cause' error raised later.
This error is only accidental because we return the port value in the return code.
This patch adds just a minor tweak to the already existing check so we
reject negative values the same way as we reject non-numerical strings.

Introduced by f6a2f97e
Problem Description:
After multiple times of migrating a domain, which has an ovs interface with no portData set,
with non-shared disk, nbd ports got overflowed.
The steps to reproduce the problem:
1 define and start a domain with its network configured as:
<interface type='bridge'>
<source bridge='br0'/>
<virtualport type='openvswitch'>
</virtualport>
<model type='virtio'/>
<driver name='vhost' queues='4'/>
</interface>
2 do not set the network's portData.
3 migrate(ToURI2) it with flag 91(1011011), which means:
VIR_MIGRATE_LIVE
VIR_MIGRATE_PEER2PEER
VIR_MIGRATE_PERSIST_DEST
VIR_MIGRATE_UNDEFINE_SOURCE
VIR_MIGRATE_NON_SHARED_DISK
4 migrate success, but we got an error log in libvirtd.log:
error : virCommandWait:2423 : internal error: Child process (ovs-vsctl --timeout=5 get Interface
vnet1 external_ids:PortData) unexpected exit status 1: ovs-vsctl: no key "PortData" in Interface
record "vnet1" column external_ids
5 migrate it back, migrate it , migrate it back, .......
6 nbd port got overflowed.
The reasons for the problem is :
1 virNetDevOpenvswitchGetMigrateData() takes it as wrong if no portData is available for the ovs
interface of a domain. (We think it's not appropriate, as portData is just OPTIONAL)
2 in func qemuMigrationBakeCookie(), it fails in qemuMigrationCookieAddNetwork(), and returns with -1.
qemuMigrationCookieAddNBD() is not called thereafter, and mig->nbd is still NULL.
3 However, qemuMigrationRun() just *WARN* if qemuMigrationBakeCookie() fails, migration still successes.
cookie is NULL, it's not baked on the src side.
4 On the destination side, it would alloc a port first and then free the nbd port in COOKIE.
But the cookie is NULL due to qemuMigrationCookieAddNetwork() failure at src side. thus the nbd port
is not freed.
In this patch, we add "--if-exists" option to make ovs-vsctl not raise error if there's no portData available.
Further more, because portData may be NULL in the cookie at the dest side, check it before setting portData.

Undefining a running, autostarted domain removes the autostart link, but
dom->autostart is not cleared. If the domain is subsequently redefined,
libvirt thinks it is already autostarted and will not create the link
even if requested:
# virsh dominfo example | grep Autostart
Autostart: enable
# ls /etc/libvirt/qemu/autostart/example.xml
/etc/libvirt/qemu/autostart/example.xml
# virsh undefine example
Domain example has been undefined
# virsh define example.xml
Domain example defined from example.xml
# virsh dominfo example | grep Autostart

# virsh autostart example
Domain example marked as autostarted
# ls /etc/libvirt/qemu/autostart/example.xml
ls: cannot access /etc/libvirt/qemu/autostart/example.xml: No such file or directory
This commit ensures dom->autostart is cleared whenever the config and
autostart link (if present) are removed.
The bridge network driver cleared this flag itself in networkUndefine.
This commit moves this into virNetworkDeleteConfig for symmetry with
virDomainDeleteConfig, and to ensure it is not missed in future network

So, libvirt uses pid file to track pid of started qemus. Whenever
a domain is started, its pid is put into corresponding pid file.
The pid file path is generated based on domain name and stored
into domain object internals. However, it's not stored in the
status XML and therefore lost on daemon restarts. Hence, later,
when domain is being shut down, the daemon does not know which
pid file to unlink, and the correct pid file is left behind. To
avoid this, lets generate the pid file path again in
qemuProcessReconnect().

STREQ_NULLABLE() is safe to use since the code in question is wrapped in

Trying to use qemu:///session to create a storage pool pointing at
/tmp will usually fail with something like:
$ virsh pool-start tmp
error: Failed to start pool tmp
error: cannot open volume '/tmp/systemd-private-c38cf0418d7a4734a66a8175996c384f-colord.service-kEyiTA': Permission denied
If any volume in an FS pool can't be opened by the daemon, the refresh
fails, and the pool can't be used.
This causes pain for virt-install/virt-manager though. Imaging a user
downloads a disk image to /tmp. virt-manager wants to import /tmp as
a storage pool, so we can detect what disk format it is, and set the
XML correctly. However this case will likely fail as explained above.
Change the logic here to skip volumes that fail to open. This could
conceivably cause user complaints along the lines of 'why doesn't
libvirt show $ROOT-OWNED-VOLUME-FOO', but figuring that currently
the pool won't even startup, I don't think there are any current
users that care about that case.

So we have this bug. The virConnectGetDomainCapabilities() API
performs a couple of checks before it produces any result. One of
the checks is if the architecture requested by user can be run by
the binary (again user provided). However, the check is pretty
dumb. It merely compares if the default binary architecture
matches the one provided by user. However, a qemu binary can run
multiple architectures. For instance: qemu-system-ppc64 can run:
ppc, ppcle, ppc64, ppc64le and ppcemb. The default is ppc64, so
if user requested something else, like ppc64le, the check would
have failed without obvious reason.

- Remove all qemu emulators
- Restart libvirtd
- Install qemu emulators
- Call 'virsh version' -> errors
The only thing that will force the qemu driver to refresh it's cached
capablities info is an explict API call to GetCapabilities.
However in the case when the initial caps lookup at driver connect didn't
find a single qemu emulator to poll, the driver is effectively useless
and really can't do anything until it's populated some qemu capabilities
info.
With the above steps, the user would have to either know about the
magic refresh capabilities call, or restart libvirtd to pick up the
changes.
Instead, this patch changes things so that every time a part of th
driver requests access to capabilities info, check to see if
we've previously seen any emulators. If not, force a refresh.
In the case of 'still no emulators found', this is still very quick, so
I can't think of a downside.
