[Users] Fwd: oVirt Users Guest Usage Survey
by Vinzenz Feenstra 12 Jun '13

12 Jun '13

Hi, I would like to ask everyone to please take the time to answer the following survey: http://goo.gl/ADYiT We'd like to see what's the common usage of the oVirt environment in the community :-) This is mainly due to the direction we're going to take with the oVirt guest agent, so we can focus on supported OS and see what features are required to be functional on those to be most useful to the community. Thanks a lot :-) -- Regards, Vinzenz Feenstra | Senior Software Engineer RedHat Engineering Virtualization R & D Phone: +420 532 294 625 IRC: vfeenstr or evilissimo Better technology.

It seems the VM keeps working on the old interface and the new configuration does not work. Any idea?

[Users] Same VLAN id, for different physical networks.
by Alfred Angelov 12 Jun '13

12 Jun '13

Hey, in my ovirt datacenter, I have two physical networks (one I use for access, and one is internal for runing backups etc). They have different IP addresses, but are created with same VLAN ids on both physical networks. When I try to add those two networks in ovirt i get a (when I try to add a VLAN with id 4): Error: The specified VLAN ID (4) is already in use. Anyone had simmilar issues and is there a way to fix this? -- Mvh Alfred Angelov

by Marc Seward 12 Jun '13

Hi all, In a 2 hypervisor setup,if host1 is fenced(host1 is also the SPM host) and it has HA VMs running on it,would these VMs be started on host2 only after host2 is elected as the SPM host? Thanks for your help.

[Users] update SpiceX.cab for win client?
by Darrell Budic 11 Jun '13

11 Jun '13

The spice.cab from elmarco that is referred to on http://wiki.ovirt.org/How_to_Connect_to_SPICE_Console_With_Portal doesn't exist any more, and I see that spice-space.org has a virt-viewer 0.5.6 for windows out. Any chance of someone packaging it up in a compatible .cab? Or if there's a resource on how to do it, a pointer would be appreciated and I can tackle it. Thanks! -Darrell

Re: [Users] iSCSI and snapshots
by Maor Lipchuk 11 Jun '13

11 Jun '13

Hi Juan, When creating a snapshot, a new volume is should be created in the storage. The snapshot should contain the VM configuration and the VM disks (not including shareable disks and direct lun disks). Which Ovirt version are you using? What the audit log indicated? Was the operation succeeded? Can u please add a print screen of your VM and snapshot?

[Users] Nested virt failing
by Dax Kelson 10 Jun '13

10 Jun '13

I have Fedora 18 with ovirt running. I have vdsm-hook-nestedvt.noarch installed on all the nodes. The nodes are all identical with Intel i5-2400 CPUs (SandyBridge). When I try to boot a nested virtual machine (L2) instead of a ovirt virtual machine (L1), the kernel starts to load, and then that nested virtual machines (L2) pauses. On the host running Fedora 18 dmesg shows this message: nested_vmx_run: VMCS MSR_{LOAD,STORE} unsupported Reading this bug https://bugzilla.redhat.com/show_bug.cgi?id=892240 It looks like if the Fedora 18 ovirt nodes started the the L1 using the "core2duo" CPU flag instead of host pass through it might work? How do I do that, or are there other solutions? TIA, Dax Kelson
