Rollback imageof kvm guest
 

Good morning, I have a fedora server, in which I have kvm with virt-manager. The images of the guests are qcow2. Days ago by mistake 2 images of 2 guests were deleted. Both are in the snapshot the day before, but I can't put them back in the location where they were deleted. The snapshots are made with btrfs, the partition of the vm and the snapshots is the same

Hello.

I'll venture some questions since this has been sitting a while.

"The snapshots are made with btrfs, the partition of the vm and the snapshots is the same"
Are you saying the host or client is btrfs? I assume you mean host.

Something like this should bring file to the btrfs system if I get question correctly. https://fedoramagazine.org/recover-y...rfs-snapshots/

Hello, sorry for the delay in answering. yes, I mean the host. Before any problem, cp /mnt/snapshots/server/serverimage.qcow2 / mnt / vm / server / for example.
At this moment, when doing the example, cp throws the input / output error. Solve by copying with rsync and the --inplace function (at the end of the copy rsync also gave an error and began to copy again, but what was already copied was in its entirety and working.
Now, the cp and rsync errors, are they disk errors? btrfs partition? Do not know.
