Hi
I am using OpenNebula 5.8 and today got a serious issue with qcow2 disk. One of my running VM with qcow2 disk show crashed. I found the vm disk was full and tried to resize the disk but no luck.

Have you made a copy of the disk?
what is datastore type your are using?
I am using the default shared datastore and tried to copy the disk but the output is the same.
if you use “system” file usually transferred via ssh. and this is slow and unstable.
I had similar issue.
Now I’m using only qcow2_shard
