Re: [ovirt-users] Can I use qcow2?
Hi, I have checked and found that ovirt support two type of disk formats (RAW QCOW2)...but bydefault it create the VM disk with RAW formati try but didn't find any way to change this format to qcow2 ?? How i can change the default vm disk from RAW to QCOW2 ??

As far as I know from official RHEV docs, the better reference page is this (for RHEV 3.4): https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.4/html/Administration_Guide/Understanding_virtual_disks.html But I don't see in that table a clear statement for GlusterFS... is it like NFS? Also, in my opinion, it would be nice to add, in the first column field, the word (default) for the corresponding line if feasible.

Re: [ovirt-users] Can I use qcow2?
Hi, So, what do you recommend for glusterfs? I have try out on local storage with native qcow2 format and the vm still could start, but does not boot. It sad no bootable device found. I convert to raw and it could boot without problems. I will try out on my glusterfs based storage soon.
