Re: [ovirt-users] Issues with vm start up
Try to remove content and run the vm,
ie remove the runcmd: or some of it - try to use the xml with out CDATA maybe
you can pinpoint the problem that way...

Hi, Lev, you are correct; there is nothing to install on the guest for Spice Native USB. On the client side there is a need for remote-viewer to be configured with USB redir enabled, and having access to the device (via libusb). On a Windows client currently we use WinUSB driver to enable access to the USB device. The driver can be installed using the usbclerk service or manually (e.g. with Zadig). It must be installed for each device to be redirected. On Ovirt, as mentioned, Native Spice USB option has to be enabled. (This would also add the virtual usb devices needed on the qemu-kvm/spice-server side). Hope that helps, Uri. The user/admin only needs to properly configure the VM for Native USB redirection and install the Spice client. I forwarded the issue to the Spice team, they could properly point to the issue.

If you don't use multipath then add a blacklist section to your

blacklist {

Now, if you do use multipath you can whitelist the paths that you want.

Re: [ovirt-users] Reclaim/Trim/issue_discards : how to inform my LUNs about disk space waste?
Hi Nicolas, you can find more information on this at: https://bugzilla.redhat.com/show_bug.cgi?id=981626 First of all an important note (that was already mentioned): vdsm is not using lvm.conf, so whatever change you make there it won't affect vdsm behavior. Anyway long story short, enabling issue_discards in lvm would lead to lvm commands starvation when the lv that you're removing is large and the granularity is small. The correct solution is to use blkdiscard on the lv and I happened to submit a patch series for that yesterday: http://gerrit.ovirt.org/#/q/status:open+project:vdsm+branch:master+topic:block-discard,n,z (very much experimental) The approach is to begin with issuing blkdiscard when wipe after delete is selected on the disk. That is because blkdiscard in the majority of the cases will wipe the lv data and I know that someone in the past has been brave enough to try and recover data from a mistakenly removed lv that wasn't post-zeroed. Anyway extending the support to non post-zero is trivial and it's just a matter of agreement and expectations. With regard to the legitimate question of why both post-zero and block discard, the answer is that after discussing it with storage array experts it seems that blkdiscard has no contract in guaranteeing that the data will be blanked out and it could later on show up even on a completely different LUN of the same storage. -- Federico - Original Message - From: Nicolas Ecarnot nico...@ecarnot.net To: Federico Simoncelli fsimo...@redhat.com Cc: users users@ovirt.org Sent: Thursday, November 27, 2014 10:43:06 AM Subject: Re: [ovirt-users] Reclaim/Trim/issue_discards : how to inform my LUNs about disk space waste?

Re: [ovirt-users] 答复: Ovirt 3.5 Bug !!!!!!!!!!!!!!!!!!
Hi guys, Simone: I don't think spice proxy helps in this case - the customers have two separate networks. Where should be the proxy placed then? Paul: - I still think that solution with a new display network accessible for both customers should be the intended way to do it. - But if you can't do it, you can try deploying a small vdsm hook i just wrote on all your hosts. It makes spice/vnc server listen on all interfaces (exactly the behavior of 3.4 by default). You can find it here [1]. You can deploy this hook (.py file) by placing the file in the hooks directory (/usr/libexec/vdsm/hooks/before_vm_start on Fedora) and renaming it to something meaningful (console_listen_on_all_ifs.py). Then configure in [vars] section /etc/vdsm/vdsm.conf by putting this line: console_listen_on_all_ifs = true Then restart vdsm and try running a vm and check if spice/vnc listens on all ifs.

Dear ALL,
[ovirt-users] Backup solution using the API
Hello, now that our oVirt Cluster runs great, I'd like to know if anybody has done a backup solution for oVirt before. My basic idea goes as follows: - Create a JSON file with machine's preferences for later restore, create a snapshot, snatch the disk by its disk-id (copy it to the fileserver), then deleting the snapshot and be done with it. - On restore I'd just create a new VM with the Disks and NICs specified in the preferences; then I'd go ahead and and put back the disk... t I've played a little bit around with building a JSON file and so far it works great; I haven't tried to make a VM with that, though... Using the export domain or a simple export command is not what I want since you'd have to turn off the machine to do that - AFAIK. Correct me if that should not be true. Now, before I go into any more hassle, has somebody else of you done a live-backup solution for oVirt? Are there any recommendations? Thanks for any help provided!

[ovirt-users] failures in vdsm logs Ovirt 3.5 Gluster 3.6.1
I see very frequents errors in the vdsm log on one of the gluster servers
in my gluster cluster. The host is fine in the ovirt console, as are the
volumes, and gluster functions ok, so this is a nuisance primarily. The
gluster cluster is a replica 2, with 2 hosts, both CentSO 6.6 with gluster
version 3.6.1, vdsm version 4.16.7. Ovirt engine version 3.5.0.1-1.fc20
the host producing the errors is identified by fqdn in ovirt, the one that
does not produce errors is identified by ip address.
Any ideas about how to trouble shoot this?
-Thanks, Alastair
Gluster Server VentOS 6.6:
vdsmd: vdsm-4.16.7-1.gitdb83943.el6
gluster: glusterfs-3.6.1-1.el6
