 Subject: [ovirt-users] alternate method of fencing
 
 
 
 Is there a way to force oVirt to place a host into maintenance mode
 automatically when a problem occurs? The problem we have is separate
 networks for everything:
 
 
 
 2 public nics which are bonded active/backup for internet access
 
 4 bonded gigabit nics for our Gluster network
 
 1 IPMI
 
 
 
 The ipmi is on a completely different network, not attached to anything else
 other than a VPN.
 
 
 
 ///
 
 
 
 Our cluster servers shared Gluster  hypervisor on the same hosts, which
 works great however, all are 1U servers so we don’t have room for another
 NIC to dedicate to just an ipmi network connection in addition to the ipmi
 card itself. Even if the PSU on a host fails, then the ipmi power management
 is useless anyhow and the VM’s on that host will not be moved.
 
 
 
 I’ve tested putting a host into maintenance mode with running VM’s and it
 will auto-migrate the VM’s without issue. Is there a way to make oVirt just
 force a host into maintenance mode if there’s some sort of problem or some
 other fencing mechanism that will allow the VM’s to be migrated to another
 host?

I think this is a scheduling issue rather than fencing , please take a look at
