oVirt-3.4.Z and maybe 3.5.Z too and Fedora20
by Joop 29 Oct '14

29 Oct '14

FYI, Just spend the better part of the day debugging a weird issue. Running 'yum update' on a CentOS-6.5 VM causes a kernel OOPS on the host :-( The oops is in the nfs module (_put_nfs_open_context) and it looks like there is work being done on it. Kernel(s) tried are all 3.16.x. Switching back to the latest F19 kernel (is an updated system) and then there is no crash anymore. Tried all kinds of variations with different NFS servers, different hosts, different kernels but I get the OOPS always during the yum update sooner or later. (updated ofcourse a lot of things before I hit this :-( ) Regards, Joop

I've been trying to work out some pattern and realized that the VMs using that much cpu all are Redhat 5.x, the Readhat 6.x doesn't exhibit this kind of high cpu use. (we run only redhat/centos 5.x/6.x on the cluster) I'll take a look to the KSM config. Cheers, Xavier

Ovirt VM Performance abd CPU times
by Xavier Naveira 29 Oct '14

29 Oct '14

Hi, We are migrating our ifrastructure from kvm+libvirt hypervisors to ovirt. Everything is working fine but we're noticing that all the qemu-kvm processes in the hypervisors take a lot of CPU. The typical example is an idle machine, running top from the machine itself it reports cpu use percentages below 10% and loads (with 2 processors) of 0.0x. The process running that machine in the hypervisor rports cpu uses in the order of the 80-100%. Should the values look like this? Why are the idle machines eating up so much CPU time? Thank you. Xavier

[QE][ACTION NEEDED] oVirt 3.5.1 RC status
by Sandro Bonazzola 29 Oct '14

29 Oct '14

Hi, We're going to start composing oVirt 3.5.1 RC on *2014-11-25 08:00 UTC* from 3.5 branch. Maintainers: - Please be sure that 3.5 snapshot allow to create VMs before *2014-11-24 15:00 UTC* - Please be sure that no pending patches are going to block the release before *2014-11-24 15:00 UTC* - If any patch must block the RC release please raise the issue as soon as possible. A bug tracker [1] has been opened and shows no open blockers. There are still 193 bugs [2] targeted to 3.5.1. Excluding node and documentation bugs we still have 164 bugs [3] targeted to 3.5.1. Maintainers / Assignee: - Please add the bugs to the tracker if you think that 3.5.1 should not be released without them fixed. - Please update the target to 3.5.2 or later for bugs that won't be in 3.5.1: it will ease gathering the blocking bugs for next releases. - Please fill release notes, the page has been created here [4] Community: - If you're testing oVirt 3.5 nightly snapshot, please add yourself to the test page [5] [1] http://bugzilla.redhat.com/1155170 [2] http://goo.gl/7G0PDV [3] http://goo.gl/6gUbVr [4] http://www.ovirt.org/OVirt_3.5.1_Release_Notes [5] http://www.ovirt.org/Testing/oVirt_3.5.1_Testing -- Sandro Bonazzola Better technology.
