Having multiple addresses having same hostname is a common config either
to have IPv4 and IPv6 address for the same hostname or even for DNS
round robin. The validation in the network update code didn't allow
adding such entries despite the fact that it is possible to define a
network with them.
Don't check hostname duplicity when adding a DNS entry.
The update of the test case adds another entry for the 'pudding'
hostname which is added in one of the networkxml2xmlupdate test cases.

We need to report via domcapabilities if specifying shared memory

out if domain has suitable setup to make virtiofs work.
The solution is to report source types of memory backing to

If the attempt to attach a device failed, we erased the
unattached device from the namespace. This resulted in erasing an
already attached device in case of a duplicate. We need to check
for existing file in the namespace in order to determine erasing
it in case of a failure.

A new apparmor profile initially derived from the libvirtd profile.
All rules were prefixed with the 'audit' qualifier to verify they
are actually used by virtxend. It turns out that several, beyond
the obvious ones, can be dropped in the resulting virtxend profile.

This is a followup for commit e906c4d02bdcddf141b4d124afd68c8ee10134fe
("apparmor: Allow /usr/libexec for libxl-save-helper and pygrub"):
In recent rpm versions --libexecdir changed from /usr/lib64 to
/usr/libexec. A plain rpmbuild %configure in xen.git will install all
files, including the private copies of qemu, into /usr/libexec/xen/bin.
Expand the existing pattern to cover also this libexecdir variant.

The 'storageMigration' flag is supposed to be true if storage migration

QEMU_MONITOR_MIGRATE_NON_SHARED_INC (0x04) instead of
VIR_MIGRATE_NON_SHARED_INC (0x80), caused libvirtd to skip the actual
