Hello,
we've had 5+ different windows systems fail backup/restore or migrations. the following is a paste of work notes... I'll edit later but have to finish for today. In all cases we were trying to move a kvm from non cluster pve's to our new cluster.
========================
restored win7 kvm backup to main node.
after start this displays on console. it stays stuck .
this has happened a few times before. never on a linux system.
cache is set to Default.
try some suggestions from forum
__ 1 core - NOPE
__ 2gb ram - NOPE
__ cpu type - host. NOPE. put back to default.
__ no cdrom . none was alread set.
_ try convert disk from raw to qcow2 NOPE
- check for a different type of migration. use cli . rsync _____________ Did not check and do.
- try restoring the kvm to pve87 , which has the same cpu, and motherboard .
THAT WORKED. SO SIMILAR HARDWARE IS NEEDED.
ON 1-ST BOOT THIS POPPED UP ON WINDOWS DESKTOP:
Windows created a temporary paging file on your computer because of a problem that .......3 more lines....
-----------------------------------------------------------------------------------
Document the nodes:
cat /proc/cpuinfo from . note just the last core is reported.
node running windows kvm was getting moved from. migration and backup / restore were tried.
restore failed here:
node that restore was successful on:
pveversion -v is the same on all 3 nodes [ except list of unused kernels].
===========================
I think there is a bug with kvm backup / restore or migration between different cpu's or devices.
Maybe it is not a bug and that is how windows is designed.

Maybe it is not a bug and that is how windows is designed.
