Due to the way the information is stored by the XML parser, we've
had this quirk where specifying any information about the loader
or NVRAM would implicitly set its format to raw. That is,
<nvram>/path/to/guest_VARS.fd</nvram>
would effectively be interpreted as
<nvram format='raw'>/path/to/guest_VARS.fd</nvram>
forcing the use of raw format firmware even when qcow2 format
would normally be preferred based on the ordering of firmware
descriptors. This behavior can be worked around in a number of
ways, but it's fairly unintuitive.
In order to remove this quirk, move the selection of the default
firmware format from the parser down to the individual drivers.
Most drivers only support raw firmware images, so they can
unconditionally set the format early and be done with it; the
QEMU driver, however, supports multiple formats and so in that
case we want this default to be applied as late as possible,
when we have already ruled out the possibility of using qcow2
formatted firmware images.

The libxl driver has basic support for VIR_MIGRATE_CHANGE_PROTECTION
by starting and stopping modify jobs in the begin/confirm and prepare/finish
phases of migration, but it doesn't advertise that support. This can result
in unterminated jobs because the migration logic skips phases of migration
when the VIR_MIGRATE_CHANGE_PROTECTION feature is absent. Ensure jobs are
terminated properly by advertising support for VIR_MIGRATE_CHANGE_PROTECTION.

For unknown reasons, the libxl driver attempts to resume a domain in the
confirm phase when a migration operation has been canceled. This has shown
to be problematic when simulating scenarios that result in a canceled
migration. In all scenarios, the domain was in a running state when entering
libxlDomainMigrationSrcConfirm, causing the call to libxl_domain_resume to
fail. Making matters worse, the domain state is changed to paused when in
fact it's running. And finally, libxlDomainMigrationSrcConfirm incorrectly
returns an error.
Remove this incorrect logic from libxlDomainMigrationSrcConfirm. On a
canceled migration it's sufficient to resume the lock process that was
paused in the perform phase.

Xen toolstack has gained basic Virtio support recently which becides
adding various virtio related stuff introduces new disk backend type
LIBXL_DISK_BACKEND_STANDALONE [1].
Unfortunately, this caused a regression in libvirt build with Xen support
enabled, reported by the osstest today [2]:
CC libxl/libvirt_driver_libxl_impl_la-xen_xl.lo
../../src/libxl/xen_xl.c: In function 'xenParseXLDisk':
../../src/libxl/xen_xl.c:779:17: error: enumeration value 'LIBXL_DISK_BACKEND_STANDALONE'
not handled in switch [-Werror=switch-enum]
switch (libxldisk->backend) {
^~~~~~
cc1: all warnings being treated as errors
The interesting fact is that switch already has a default branch (which ought
to cover such new addition), but the error is triggered as -Wswitch-enum
gives a warning about an omitted enumeration code even if there is a default
label.
Also there is a similar issue in libxlUpdateDiskDef() which I have reproduced
after fixing the first one, but it that case the corresponding switch doesn't
have a default branch.
Fix both issues by inserting required enumeration item to make the compiler
happy and adding ifdef guard to be able to build against old Xen libraries
as well (without LIBXL_HAVE_DEVICE_DISK_SPECIFICATION). Also add a default
branch to switch in libxlUpdateDiskDef().
Please note, that current patch doesn't implement the proper handling of
LIBXL_DISK_BACKEND_STANDALONE and friends, it is just intended to fix
the regression immediately to unblock the osstest. Also it worth mentioning
that current patch won't solve the possible additions in the future.
