Commit 6534b3c4 tried to raise an error when there is no numa
nodes by setting access='shared' in the domain config, but added
a helper called from qemuDomainDeviceDefValidate instead of a
helper called from qemuDomainDefValidate for XML:
<memoryBacking>
<hugepages/>
<access mode='shared'/>
</memoryBacking>
Since there are no memory devices in the test XML, there would
be no validation failure, but the test added was still failing.
Investigating that it turns out that unnecessary XML elements
were causing the failure (no need for <video>, <graphics>,
<pm>, usb controller model "piix3-uhci", disk attribute for
"discard='unmap'", <serial>, <console>, <channel> and a
memballoon model). Removing all those before moving the method
caused the test to succeed.
So this patch moves the validation to the right place and
removes all the unnecessary XML pieces that were causing
a false validation failure.

Refactor helper virNumaGetHugePageInfoPath to handle returning a directory
path when passed a page_size of 0 and suffix == NULL into a new helper
virNumaGetHugePageInfoDir which will only be called when a directory
path is expected to be returned. This solves the issue where the helper
was called with page_size == 0 expecting a file path in return, but
instead got a directory path and failed in virFileReadAll with:
error : virFileReadAll:1358 : Failed to read file
'/sys/devices/system/node/node0/hugepages/': Is a directory
Since virNumaGetPages API expects to return a directory by passing
page_size == 0 and suffix == NULL, it will now call the new helper.
Callers to virNumaGetHugePageInfoPath expect to return a file path
which could then be used in the call to virFileReadAll.

If the qemu monitor fails to remove the memory from the guest for
any reason, the auditlog message will incorrectly use the current
actual memory (via virDomainDefGetMemoryActual) instead of the
value we were attempting to reduce to. The result is the 'new-mem'
and 'old-mem' values for the auditlog message would be identical.
This patch creates a local 'newmem' which accounts for the current
memory size minus the memory which is being removed. NB, for the
success case this results in the same value that would be returned
by virDomainDefGetMemoryActual without the need to do the math. This
follows the existing code which would subtract the size for cur_balloon.

Prior to this patch, after successfully hot plugging memory
the audit log indicated that the update failed, e.g.:
type=VIRT_RESOURCE ... old-mem=1024000 new-mem=1548288 \
exe="/usr/sbin/libvirtd" hostname=? addr=? terminal=pts/2 res=failed
This patch will adjust where virDomainAuditMemory is called to
ensure the proper 'ret' value is used based on success or failure.
Additionally, the audit message should include the size of the
memory we were attempting to change to rather than the current
actual size. On failure to add, the message showed the same value
for old-mem and new-mem.
In order to do this, introduce a 'newmem' local which will compute
the new size based on the oldmem size plus the size of memory we
are about to add. NB: This would be the same as calling the
virDomainDefGetMemoryActual again on success, but avoids the
overhead of recalculating. Plus cur_balloon is already adjusted
by the same value, so this follows that.

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

When starting a VM with hotpluggable memory devices the user may specify
an invalid source NUMA node. Libvirt would pass through the error from
qemu:
# virsh start test3
error: Failed to start domain test3
error: internal error: process exited while connecting to monitor:
2015-03-25T01:12:17.205913Z qemu-kvm: -object memory-backend-ram,id=memdimm0
,size=536870912,host-nodes=1-3,policy=bind: cannot bind memory to host NUMA nodes:
Invalid argument
This patch adds a check that allows to report better error:
# virsh start test3
error: Failed to start domain test3
error: configuration unsupported: NUMA node 1 is unavailable

Commit 5bba61f changed the XPath strings to be absolute when parsing
the VM NUMA configuration. Unfortunately the <domain> element is not a
top level element when parsing the domain status XML thus the absolute
XPath string doesn't match.
Use the relative string so that the <numa> settings are not lost.

When qemu exits during startup, libvirt includes the error from
/var/log/libvirt/qemu/vm.log in the error message:
$ virsh start test3
error: Failed to start domain test3
error: internal error: early end of file from monitor: possible problem:
2015-02-27T03:03:16.985494Z qemu-kvm: -numa memdev is not supported by
machine rhel6.5.0
The check for domain liveness added to qemuDomainObjExitMonitor
in commit dc2fd51f sometimes overwrites this error:
$ virsh start test3
error: Failed to start domain test3
error: operation failed: domain is no longer running
Fix the check to only report an error if there is none set.

Jumping to the cleanup label prior to starting the container failed to
properly clean everything up that is handled by the virLXCProcessCleanup
which is called if virLXCProcessStop is called on failure after the
container properly starts. Most importantly is prior to this patch none
of the stop/release hooks, host device reattachment, and network cleanup
(that is reverse of virLXCProcessSetupInterfaces).

Move the two console checks - one for zero nconsoles present and the
other for an invalid console type to earlier in the processing rather than
getting after performing some setup that has to be undone for what amounts
to an invalid configuration.
This resolves the above bug since it's not not possible to have changed
the security labels when we cause the configuration check failure.

virsh's domdisplay command looks in /domain/devices/graphics/@listen
of the domain's XML for the listen address, however for listen
type='network' (added in libvirt 0.9.4), the <graphics> element
doesn't have a listen attribute, but has a <listen> subelement,
*still* with no address (this is the inactive XML):
<graphics type='spice' autoport='yes' keymap='en-us'>
<listen type='network' network='default'/>
</graphics>
However, at domain start time the <listen> subelement gets its address
attribute filled in once libvirt figures out the IP address associated
with the named network (this is the status XML):
<graphics type='spice' port='5901' autoport='yes' keymap='en-us'>
<listen type='network' address='192.168.122.1' network='default'/>
</graphics>
So in these cases, we need to look at
/domain/devices/graphics/listen/@address instead.
Even though another patch is being pushed that will backfill
listen/@address into @listen, this patch is still useful, as it fixes
domdisplay for cases of a new virsh (with this patch) connecting to a
libvirtd that is newer than 0.9.4 but doesn't have the followup patch.

When we attempt to migrate a vm with a migrateuri that has no scheme:
# virsh migrate test4 --live qemu+ssh://lhuang/system --migrateuri 127.0.0.1
target libvirtd will crash because uri->scheme is NULL in
qemuMigrationPrepareDirect on this line:
if (STRNEQ(uri->scheme, "tcp") &&
Add a value check before this line. Also fix a bug like this in
doNativeMigrate, that could only happen when destination libvirtd
returned an incorrect URI.

Libvirt didn't prefix the random number generator backend object alias

To avoid possible problems, rename the alias for the backend object and
tweak tests to comply with the change.
