[Users] Guests accessing multiple host disks in oVirt

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 ?!? )
