Alexis, Use "Clusters" -> "Logical Networks" -> "Manage Networks" for assigning network for migrations. It's ovirtmgmt by default. Note that migration network has to have IPs on hosts. Hosts have VDSM configuration option - [vars]/migration_max_bandwidth in /etc/vdsm/vdsm.conf. It's 52MB/s by def

SpiceViewer is quite old. It just doesn't work well. Two issues: 1. It's slow. It takes the whole couple seconds to scroll text screen by one line. 2. It tries to hide the mouse cursor in the bottom right corner. This activates Hot Corners action. http://thesweetsetup.com/quick-tip-enable-hot-corn

Fernando, oVirt supports thin provisioning for shared block storages (DAS or iSCSI). It works using QCOW2 disk images directly on LVM volumes. oVirt extends volumes when QCOW2 is growing. I tried GFS2. It's slow, and blocks other hosts on a host failure. -Original Message- From: on be

Luigi, It’s necessary to put a host into maintenance mode before shutdown. That panic is a kernel reaction to NMI, which is triggered by hardware watchdog, which is set by wdmd daemon, which is used by sanlock. This scheme is intended to hardware reset a server if it has lost connection to its
