separately from the unmanaged one. There is only one managed object so
handling it with disks is awkward and does not scale well when backing

The encryption was buggy and qemu actually dropped it upstream. Forbid
it for all versions since it would cause other problems too.
Problems with the old encryption include weak crypto, corruption of
images with blockjobs and a lot of usability problems.
This requires changing of the encryption type for the encrypted disk
tests.

Previously we did not store the aliases but rather re-generated them
when unplug was necessary. This is very cumbersome since the knowledge
when and which alias to use needs to be stored in the hotplug code as
well.
While this patch will not strictly improve this situation since there
still will be two places containing this code it at least will allow to
remove the mess from the disk-unplug code and will prevent introducing
more mess when adding blockdev support.

Commit 656151bf fixed formatting of the <cmdline> element. Perhaps it
would have been noticed and fixed earlier if we had a test. With this
change, all possible cases of formatting <cmdline> from xmconfig are
covered
1. no 'extra=' or 'root=' in xm.cfg
2. 'extra=' but no 'root=' in xm.cfg
3. 'root=' but no 'extra=' in xm.cfg
4. both 'root=' and 'extra=' in xm.cfg
Case 1 is covered by all existing paravirt tests since they have no
'extra=' or 'root='. Case 2 is covered by adding 'extra=' to a few

When preparing qemuCaps for test cases the following is
happening:
qemuTestParseCapabilitiesArch() is called, which calls
virQEMUCapsLoadCache() which in turn calls
virQEMUCapsInitHostCPUModel() which sets qemuCaps->kvmCPU and
qemuCaps->tcgCPU.
But then the code tries to update the capabilities:
testCompareXMLToArgv() calls testUpdateQEMUCaps() which calls
virQEMUCapsInitHostCPUModel() again overwriting previously
allocated memory. The solution is to free host cpuData in
testUpdateQEMUCaps().

The VM Generation ID is a mechanism to provide a unique 128-bit,
cryptographically random, and integer value identifier known as
the GUID (Globally Unique Identifier) to the guest OS. The value
is used to help notify the guest operating system when the virtual
machine is executed with a different configuration.
This patch adds support for a new "genid" XML element similar to
the "uuid" element. The "genid" element can have two forms "<genid/>"
or "<genid>$GUID</genid>". If the $GUID is not provided, libvirt
will generate one and save it in the XML.
Since adding support for a generated GUID (or UUID like) value to
be displayed modifying the xml2xml test to include virrandommock.so
is necessary since it will generate a "known" value.
