From the private summary:
Description of problem:
Cannot restore snapshot that contains memory state when the VM is set (in ovirt) with disabled/legacy usb support. it works fine when it is set with native usb support.
The error I see in libvirt's log is:
unsupported configuration: Target controller type ide does not match source usb
And the upstream fixes:

qemu: Use "migratable" XML definition when doing external checkpoints
In the original implementation of external checkpoints I've mistakenly
used the live definition to be stored in the save image. The normal
approach is to use the "migratable" definition. This was discovered when
commit 07966f6a8b5ccb5bb4c716b25deb8ba2e572cc67 changed the behavior to
use a converted XML from the user to do the compatibility check to fix
problem when using the regular machine saving.
As the previous patch added a compatibility layer, we can now change the
type of the XML in the image.

qemu: Fix checking of ABI stability when restoring external checkpoints
External checkpoints have a bug in the implementation where they use the
normal definition instead of the "migratable" one. This causes errors
when the snapshot is being reverted using the workaround method via
qemuDomainRestoreFlags() with a custom XML. This issue was introduced
when commit 07966f6a8b5ccb5bb4c716b25deb8ba2e572cc67 changed the code to
compare "migratable" XMLs from the user as we should have used
migratable in the image too.
This patch adds a compatibility layer, so that fixing the snapshot code
won't make existing snapshots fail to load.
