commit 0c710a37ea265dc7dfa0ebcebf1e21e4c6b2ea21

libxl: resume lock process after failed migration
During migration, the lock process is paused in the perform phase
but not resumed if there is a subsequent failure, leaving the locked
resource unprotected.
The perform phase itself can fail, in which case the lock process
should be resumed before returning from perform. The finish phase
could also fail on the destination host, in which case the migration
is canceled in the confirm phase and the VM is resumed. The lock
process needs to be resumed there as well.

commit 68eed56b2d51e66bb540062fe09f5ffd44e99f6e
Author: Daniel P. Berrange <berrange@redhat.com>

conf: add support for setting OEM strings SMBIOS data fields
The OEM strings table in SMBIOS allows the vendor to pass arbitrary
strings into the guest OS. This can be used as a way to pass data to an
application like cloud-init, or potentially as an alternative to the
kernel command line for OS installers where you can't modify the install
ISO image to change the kernel args.
As an example, consider if cloud-init and anaconda supported OEM strings
you could use something like
<oemStrings>
<entry>cloud-init:ds=nocloud-net;s=http://10.10.0.1:8000/</entry>
<entry>anaconda:method=http://dl.fedoraproject.org/pub/fedora/linux/releases/25/x86_64/os</entry>
</oemStrings>
use of a application specific prefix as illustrated above is
recommended, but not mandated, so that an app can reliably identify
which of the many OEM strings are targetted at it.
