What version are you using? We’ve fixed some snapshot problems in RC (4.90.10). Is it the first snapshot you’re creating in that disk or did one exist previously?

Can you retry the snapshot?

$ onevm recover --failure
$ onevm disk-snapshot-create ...

My version is OpenNebula 4.90.5 and this is the first time i try snapshot with this installation

onevm recover 28 --failure
works and makes the vm RUNNING

onevm disk-snapshot-create 28 0 test
no change, stuck in SNAPSHOT

Btw, how do i upgrade to 4.90.10, couldnt find in docs?

Thanks
