This is core part of migration. Things not migrated yet:
- DispVM (qubes_restore needs to be almost rewritten)
- VM xen config files should be fixed (use "script:" prefix in block device description, perhaps generate this files on VM start)
Huge, slow xend not needed any more, now it conflicts with libxl
This is to fix the VM lockup problem on HT processors that
occured after S3 resume (see ticket #52).
The qvm-run command now takes additional two switches:
--pause
--unpause
