Is the master release accessible via a repo.? from your question I understand that you are currently using ovirt 3.2.1 rather than master [to answer Itamar's question from the previous e-mail], and that explains the slowness of the portals on IE8 that you are experiencing. Please note that on oVirt master, the performance improvement patches for IE8 affect only the user portal; unfortunately, the admin portal still suffers from performance problems on IE8. with regards to the master release accessibility: I am not sure if we have a master release; you can build oVirt-engine directly from the code-repo by following the instructions in the following wiki-page: http://www.ovirt.org/Build_and_Install_Engine_RPM @Itamar/others: do we have some kind of a nightly/weekly/occasionally repository of ovirt builds/rpms? the IE8 performance patches were introduced to oVirt master on March 1 (almost 2 months ago), so anything rebased from ovirt master at that point in time or afterwards would be helpful. yes, there is a nightly build (it changes every night...) http://www.ovirt.org/Yum_repo_file set nightly to enabled (maybe need to disable the others). that's for fedora - I think we have one for .el6 now with 3.2.1 supporting it. eyal/moran? for master branch yes: current nightly builds are done for fedora 17/18: http://resources.ovirt.org/releases/nightly/rpm/Fedora/{17|18} and for EL6: http://resources.ovirt.org/releases/nightly/rpm/EL/6/ for 3.2.1, we don't have nightly builds, just stable release: http://resources.ovirt.org/releases/stable/rpm/EL/6/noarch/ I've been using Fedora 18. Is usb pass-through not supported for Windows clients? as Itamar mentioned below, spice-devel mailing-list members (CC'd) should be able to answer this question.

I'm regularly migrating some VMs (and stopping and starting and playing with them) with no issue, and they all are using thin provisioned disks! Could this be a common factor of the problem? also, can you please attach engine, vdsm, libvirt and the vm's qemu logs? Relevant logs : Ok, I'm in the process of collecting the logs and posting them in a useable manner. More to come. Ok, once again, I ran a test and observed the relevant logs.

I did not know what that meant (but RTFMed since), and this does not appear to disturb the other VMs - Many VMs including the problematic one have been imported from ovirt-v2v with now such issue. - This particular VM was also imported, but the starting point was a vmdk or ova single file. - Two additionnal data disks were added - As I said, this is the only running VM stored as pre allocated. Regards, One suggestion : I see no obvious errors in the log files. Could this paused state happen due to a VM's kernel panic? is this still relevant? It is! Further investigations from my colleague shown the following facts : - This VM has 3 disks. Only one of those disks is responsible for the problem - In this disk, my coworker has found only 3 files (database files) that he can do nothing with without leading to the freeze. - He tried to cat them into /dev/null, and this is leading to the freeze - He tried to copy them into another disk - freeze! We see absolutely no evidence of a kernel panic. Rather, this seems to be related to a network bottleneck between the node and the iSCSI SAN, leading to oVirt unable to sustain a sufficent bandwidth and freezing the VM. Since then, we moved to another solution, but for the sake of opensource debugging, we did kept the faulty VM for your eyes only :) -- Nicolas Ecarnot ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [Users] oVirt storage is down and doesn't come up
It looks to me like the master it is looking for is no longer there, I'm not sure what happened. What you can try to do to get your storage back up is to create a new storage domain(it won't be able to attach since your pool is not connected to the host). Then right click on the new SD and choose to re-initialize data center. It will try to reconstruct your master SD. also, just so that I have more information about the state of your system, please attach the result of: 'ls -ltr /rhev/data-center/'.
