It is senseless to have full file path in multiple locations:
- external archive
- qubes.xml
- internal archive
Also it is more logical to have only "private.img" file in archive
placed in "appvms/untrusted/private.img.000". Although this is rather
cosmetic change for VMs data, it is required to backup arbitrary
directory, like dom0 user home.
Also use os.path.* instead of manual string operations (split,
partition). It is more foolproof.
Any HVM (which isn't already template-based) can be a template for
another HVM. For now do not allow simultaneous run of template and its
VM (this assumption simplify the implementation, as no root-cow.img is
needed).
Already processed in backup prepare phase). This is only because
qfile-dom0-unpacker doesn't support selective unpack (like tar do).
This should be extended to skip also VMs not selected for restore.
This was already partially implemented, but only for backup header
(qubes.xml).
Fix handling of vmproc object (available only when backup in another
VM).
Also fix some race conditions - wait for process termination, not only
check its exit code (which would be None if process still running).
Gui daemon isn't aware of multihead parameters, also gui protocol
doesn't support such information - currently by design it is configured
via Qubes RPC service.
At GUI startup send monitor layout to the VM.
