oVirt-3.4.Z and maybe 3.5.Z too and Fedora20
by Joop
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

Change default gateway
by Finstrle, Ludek
<html><bodyHi,
I have ovirt 3.5 with hosted engine.
I'm running it on 2 physical hosts (for management + storage) directly
connected. I have another NICs for data.
-- data -- | VM_HOST1 | -- ovirtmgmt -- | VM_HOST2 | -- data --
Is it possible to setup oVirt hosts to use different network (not
ovirtmgmt but data) for default route using GUI? I think about vdsm hook
but I don't want to reinvent the wheel. Also I don't like an idea to
make hosted engine default gateway for physical hosts.
Thanks,
Luf

Hi, thank you for the answer.
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
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.
