I don't know? :-) I gave it a quick smoke-test (booted, started some guests). That should have shaken out any really weird cases. Is that good enough, or would you like further dev testing before putting it on the CentOS builders? -George

Centos 7 and Openstack
by Tom Bishop 02 Sep '14

02 Sep '14

Was wanting to go and kick the openstack tires and was wondering if anyone has loaded up the RDO version. Wasn't sure if any of the issues that were seen early on have been corrected or what needs to be done for installation on a centos 7 host? Thanks.

CentOS ovirt-3.1 repository
by Hideo Goto 02 Sep '14

Many thanks for your prompt and accurate info, Karanbir. I am going to follow your advice right now. In fact we have a 3.4 site also and found it incomparably more stable than ever, and have been discussing migration of our old sites. But Ovirt is, as you know, very update-hostile system: We still have another 3.0 site working. Thanks again. Hideo Goto

virt-preview repo for CentOS?
by Russell Bryant 02 Sep '14

02 Sep '14

Hello! I'm looking at options for configuring an OpenStack CI job that tests OpenStack components with the latest versions of libvirt and qemu. Fedora's virt-preview [1] repository is pretty much what we need. However, we would really rather run this job using CentOS. The job's configuration needs to work for longer than Fedora's release schedule would allow. Is anyone looking at doing something like this for CentOS? Thanks, [1] http://fedoraproject.org/wiki/Virtualization_Preview_Repository -- Russell Bryant

Dear sirs, We are operating an Ovirt-3.1(2) based virtual server system with approx 10 CentOS6+vdsm nodes. Engine and node server's were build using RPMs installed through the here-below Yum repository, according to the HowTo on the CentOS site (http://wiki.centos.org/HowTos/oVirt) http://dev.centos.org/centos/6/ovirt/ovirt.repo While I have another node server to add, I kew that this repository does not exists any more. I would be glad if someone could tell me where we can find the archives. Thanks in advance Hideo Goto

Masking CPU flags via libvirt xml not working?
by Nathan March 01 Sep '14

01 Sep '14

Hi, Has anyone here managed to get cpu masking working via libvirt? Intention to enable VM migrations between hosts of a different CPU generation. Inside my xml I'm providing the model as well as a list of features to specifically disable, but none of it seems to take any effect. On booting the VM I still see the disabled flags in /proc/cpuinfo <cpu match='exact' mode='custom'> <arch>x86_64</arch> <model fallback='forbid'>Westmere</model> <feature policy='disable' name='dtherm'/> <feature policy='disable' name='erms'/> <feature policy='disable' name='fsgsbase'/> <feature policy='disable' name='pts'/> <feature policy='disable' name='pln'/> <feature policy='disable' name='rdrand'/> <feature policy='disable' name='f16c'/> <feature policy='disable' name='aes'/> <feature policy='disable' name='tsc_deadline_timer'/> <feature policy='disable' name='x2apic'/> <feature policy='disable' name='dtherm'/> <feature policy='disable' name='pclmulqdq'/> </cpu> Doing a dumpxml against the domU once it's booted leaves out the entire <cpu> section, leading me to think maybe libvirt is dropping it for some reason. I've got the above <cpu> just in the main <domain> section. Anyone have this working or able to offer some suggestions? Thanks! - Nathan
