Greetings! I've already mentioned the problem of live disk migration between
different storage domains, but yesterday I found the same problem in a new
oVirt installation.
My actions after deploying oVirt are:

2) Created a virtual machine with

Specifically, how disks are stored on the storage domain in Gluster. I checked

You should also know that preallocated disks are about 20-30% faster than thin

The weekend went horribly. I created a second storage domain in order to move

Why do this? You can install Ovirt as a package using yum. Ovirt Node is simply
CentOs with included repos and ovirt install package. See Ovirt documentation

Hello, everyone! I need specialist help, because I'm already desperate. My
company has four hosts that are connected to the vault. Each host has its own
IP to access the storage, which means host 1 has an ip 10.42.0.10 and
10.42.1.10 -> host 2 has an ip 10.42.0.20 and 10.42.0.20 respectively.
