Servers Hang at 100% CPU On Migration
by Chris Jones - BookIt.com Systems Administrator 25 Aug '15

25 Aug '15

oVirt Node - 3.5 - 0.999.201504280931.el7.centos When migrating servers using an iSCSI storage domain, about 75% of the time they will become unresponsive and stuck at 100% CPU after migration. This does not happen with direct LUNs, however. What causes this? How do I stop it from happening? Thanks -- This email was Virus checked by UTM 9.

Move DataCenter or Cluster from one engine to another
by Chris Liebman 25 Aug '15

25 Aug '15

Is it possible to export a data center from one engine and import it to another? Currently I have an engine running in Europe and a set of nodes comprising a datacenter on the west coast of the US and am seeing communication issues? There are a number of other data centers that the engine in Europe is managing and I'd like to deploy an engine in closer proximity to the nodes for one data center. Has anyone one this? Is it possible? -- Chris

Fwd: Cannot add Posix Storage
by Steve Kilduff 24 Aug '15

24 Aug '15

I am having similar problem to you with ovirt and moosefs. My setup, ovirt mounts the mfs mount without problem, it is the mount detection mechanism in python. It is very specifically looking for a pattern to match the mount and failing: I hope this shows what I mean: OSError: [Errno 2] Mount of `mfsmount` at `/rhev/data-center/mnt/mfsmount` does not exist mfsmaster:9421 on /rhev/data-center/mnt/mfsmount type fuse.mfs (rw,relatime,user_id=0,group_id=0,allow_other) Source = mfsmount in first error out line, and source = ''mfsmaster:9421', and mount.py is trying to pattern match the mount and doesnt compare them correctly and fails. I hope this prods your interest again or helps a little. I will go back to figuring out if I can work around this somehow. Steve Kilduff

Re: [ovirt-users] Migrating hosts from RHEL6 to RHEL7
by matthew lagoe 21 Aug '15

21 Aug '15

It is possible to migrate a VM from 6 to 7 it is recommended however that you don't do a live migration and that you power off the VM and then turn it back on on the cluster running version 7 "Groten, Ryan" <Ryan.Groten(a)stantec.com> wrote: Has anyone succeeded in upgrading their hosts OS version from 6 to 7? I assumed it could be done without downtime and one host at a time, but when trying it out I found that RHEL7 hosts can't be placed in the same Cluster as RHEL6 ones. I then tried making a new Cluster and migrating VMs from the RHEL6 cluster to RHEL7. Initial testing seems to show that it works from RHEL6 to RHEL7 but not the other way around. Also when I select this option a warning pops up saying "Choosing different cluster may lead to unexpected results. Please consult documentation." I looked in the Admin Guide and Technical Reference Guide but don't see where these unexpected results are mentioned.

dependency with epel
by Fabrice Bacchella 21 Aug '15

21 Aug '15

I'm using ovirt on some centos servers, so i installed http://resources.ovirt.org/pub/yum-repo/ovirt-release35.rpm It provides a ovirt-3.5-dependencies.repo, which contains: [ovirt-3.5-epel] name=Extra Packages for Enterprise Linux 7 - $basearch #baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$bas… failovermethod=priority enabled=0 includepkgs=epel-release,python-uinput,puppet,python-lockfile,python-cpopen,python-ordereddict,python-pthreading,python-inotify,python-argparse,novnc,python-ply,python-kitchen,python-daemon,python-websockify,livecd-tools,spice-html5,mom,python-IPy,python-ioprocess,ioprocess,python-paramiko,python-crypto,python-cheetah,python-ecdsa,python-markdown,rubygem-rgen,ovirt-guest-agent,userspace-rcu,protobuf-java gpgcheck=1 gpgkey=https://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-7 What's the purpose of such a repo ? Having a epel.repo is very common I think, and so the line includepkgs became totally useless with it. If you have problem with a rpm stored in epel, this will protect only a few peoples.

R: PXE boot of a VM on vdsm don't read DHCP offer

--_000_8C2CD99696B62B409EBEBFDF87C83FBF59B5604A10DENU1XMAIL02p_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Further info about this case: An already installed and running VM (Centos7) with static IPv4 assignment, = if changed to DHCP mode, do not acquire the IP address.
