Hi, Firstly, I don't want make an import domain. I just want to make a vm with same parameters (disk size,ram, etc) then replace the disk images with our original disks. Tibor ----- Eredeti üzenet -----

Allon/Federico - I remember on NFS, qcow2 isn't used by default, since raw is sparse by default. (but i don't remember if it "won't work", or just not enabled by default). can one create a qcow2 disk for a VM with gluster storage?

Sorry for hijacking this thread, but is there anywhere some documentation what the default vm disk format on a given storage backend is and what storage format could be optionally selected and which storage format is not supported on that backend? -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

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_Virtualizat... 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. Gianluca

Thanks for the link. Local storage is also missing there.

I remember to have asked for something like that in the past on this list and then Tim Hildred <thildred@redhat.com> from Red Hat opened such a bugzilla entry for me so that I could comment with my open account .... see https://bugzilla.redhat.com/show_bug.cgi?id=954211 Can we ask here a similar workflow?

Well yeah, that works somehow, but why can't I open a bug on these docs? they are available to the public anyway. Everybody can investigate them for errors, but I need a red hat guy to make a report if I find an error? really?

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. Thanks, Tibor ----- Eredeti üzenet -----

I think I just won't report any doc bugs anymore, because red hat doesn't seem to want that.
for now, for lack of a better option, I suggest opening them on ovirt docs.

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 format....i 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 ?? I am using the below :- Ovirt :- 3.4.3 Glusterfs :- 3.5 Thanks, Punit On Thu, Sep 4, 2014 at 3:25 AM, Itamar Heim <iheim@redhat.com> wrote:

since file system are usually sparse by default, we use RAW which provides better performance than COW.
How i can change the default vm disk from RAW to QCOW2 ??
i thought I saw samples on how to do this via the API/CLI earlier in the thread: http://lists.ovirt.org/pipermail/users/2014-September/027147.html
I am using the below :- Ovirt :- 3.4.3 Glusterfs :- 3.5

Yes through rest-api. From the ovirt-shell you could run: $ add disk \ --vm-identifier <vm_name> \ --provisioned_size <size_in_bytes> \ --interface virtio \ --name <disk_name> \ --format cow \ --sparse true \ --storage_domains-storage_domain storage_domain.name=<gluster_domain_name> -- Federico
