Hi folks,
I'm trying to evaluate ovrit as a possible virtualization solution for my datacenter . I need some of my VMs to have access to multiple disks installed in the host so that the RAID will be configured in the guest level, this way I can optimize redundancy and /IO performance per guest. (raid0 vs raid10 vs raid 5) - this would be similar to what EC2/Openstack call ephemeral storage. Is this possible in oVirt ? A less desirable solution would be to create different RAID arrays in the host and place VM images on different arrays, is that possible ? ( according to the pdf guide this is possible in RHEL but not in oVirt node ?!? )
can you please elaborate a bit more on your use case? specifcially, are you planning on using shared storage (fc/iscsi/nfs/gluster/etc.) or local storage of each hypervisor?
