Ok, the error just happened now in the main machine. Took much more days to happen.
I picked my computer while it were sleeping but opened, and moved the mouse and saw a black screen with nothing on it. Then pressed power and soething appeared: /.../libvirt .... read only file system and then it turned off. Libvirt was running at the time so I think it was just an error saying that libvirt was trying to write to the disk. Don't know if it's related.
