Hello,
We are in the process of testing oVirt and replacing citrix all together.
A few things we are curious about but can't find any concrete information on:
Can oVirt live migrate data (VM's, etc.) to another machine in the pool/cluster in the event of a hardware failure, if the data is stored locally on the machine? For this to be possible, does it have to be on a shared storage?
not yet. live storage migration is currently only supported between storage domains in same storage pool (data center) where the host see both domains. we are working to remove the limitations in the pool design, which will allow this in a future version. oVirt supports managing VMs in host local storage, but the more powerful features are around clusters of hosts using shared storage. shared storage these days can benefit from multiple hosts local storage, via technologies like gluster, though at this point i think most run the storage nodes separatly from the virtualization hosts. NFS shared storage seems to be the easiest, iscsi, FC and posixfs are also supported. HTH, Itamar
