Vm suddenly paused with error "vm has paused due to unknown storage error"
Hi all, Since we upgraded our Ovirt nodes to CentOS 7 a vm (not a specific one but never more then one) will sometimes pause suddenly with the error "VM ... has paused due to unknown storage error". It happens now two times in a month. The Ovirt node uses san storage for the vm's running on it. When a specific vm is pausing with an error the other vm's keeps running without problems. The vm runs without problems after unpausing it.

Hello Markus, Thanks for your reply. I think this will not work in our case because the libvirtd/vm process is not crashed and after unpausing the vm runs without problems. Is it possible to unpause your vm in this situation or is the process really crashed?

Did you ever get the pausing vm's resolved and started? I am having the same issue.
