Hello everyone!

I am facing the following problem with ovirt 4.2.1, out of nowhere all virtual machines are paused and only return operals if log in via ssh on the host and execute a "virsh destroy domain", it is necessary to reactivate disk and network after this process. In the events I get the following message: VM X has been paused due to storage I / O problem.

Currently I have iscsi storage configured on a server with target and based on some test I did not identify problems of communication of the hosts to the storage

can you help me?
