Possible SELinux problems with ovirt syncronizing networks
by Jeremy Utley 18 May '15

18 May '15

Hello all! Running ovirt 3.5 on CentOS 7 currently, and running into a little problem. All my nodes are currently showing the ovirtmgmt network as unsyncronized. When I try to force them to sync, it fails. Looking at the /var/log/vdsm/supervdsm.log file on one of the nodes, it looks like it has to do with SELinux. See: http://pastebin.com/NX7yetVW Which contains a dump of the supervdsm.log file when I tried to force syncronization. Judging from what I'm seeing, after VDSM writes the new network configuration files to /etc/sysconfig/network-scripts/ifcfg-*, it attempts to run a selinux.restorecon function against those files. Since we disable SELinux by default on all our servers, this action is failing with Errno 61 (see lines 66-71 and 86-91 in the above-mentioned pastebin). Is this normal? Is ovirt expecting to run with SELinux enabled? Or am I mis-interpreting this log output? Thanks for any help or advice you can give me! Jeremy

My feedback on network setting after installing OVirt
by John Joseph 18 May '15

18 May '15

Hi All, Like to give my feedback about how the network interface behaved after OVirt I have used CentOS 6.6 64 bit, updated Ovirt stable from the repo Now after the installation, and configuration you get "ovirtmgmt" interface and "ovirtmgmt" interface gets the IP address and everything is fine . Now reboot it result is that when you give ifconfig , eth0 is not displayed and "ovirtmgmt" do not have IP address This stage solved by giving ifconfig eth0 up and restarting the network, it will give "ovirtmgmt" an IP now I tested it using different installation, with DHCP or manual configuration for eth0 , in both the case the same experience Giving my feedback, thanks

ovirt-agent: is it possible to run specific actions when taking snapshots?

When a VM has the ovirt-agent installed, ovirt could tell the agent to run site-speficic actions.

Live migration qemu 2.1.2 -> 2.1.3: Unknown savevm section
by Markus Stockhausen 15 May '15

So starting with the OVirt mailing list. We are using OVirt with FC20 nodes with enabled virt-preview. Thus we are running qemu 2.1.2. Everything is working smoothly including live merge. For testing purposes we compiled qemu 2.1.3 from Fedora koji and updated one of the hosts. Trying to migrate a running VM to the new host fails with the message Unknown savevm section or instance 'kvm-tpr-opt' 0 I guess some incompatibility between the versions. But qemu git history between 2.1.2 and 2.1.3 gives no hints about the reason. Any ideas - or is that migration scenario not supported at all?

status of ovirt 3.5.1 with centos 7.1
by Jason Keltz 15 May '15

15 May '15

Hi. I wanted to check on the status of ovirt 3.5.1 with CentOS 7.1. I'm pretty sure the current 3.5.1 engine has problems with CentOS 7.1 (?), but not sure about vdsm? I know that 3.5.2 will resolve issues with engine... (I'm asking because I've kickstarted CentOS 7.1 as a host, and am having a few problems (eg. unable to talk to power management) and want to avoid debugging if it's already known to be broken... :) Thanks! Jason.

Problems with installing second host with hosted engine
by Tigran Baluyan 15 May '15

15 May '15

Hi, I've stumbled across a very strange bug and been trying to work around it for a couple of days with no luck. So my setup is: Host 1: centos 6.6 with ovirt 3.5 deployed as hosted engine. Had a few problems while deploying it, but eventually got it up and running. Host 2: same centos 6.6, same hardware. While executing hosted-engine --deploy, I am getting this error: [ INFO ] Stage: Setup validation [WARNING] Host name hyp-A2 has no domain suffix [WARNING] Failed to resolve hyp-A2 using DNS, it can be resolved only locally [ ERROR ] Failed to execute stage 'Setup validation': [Errno 2] No such file or directory: '/rhev/data-center/mnt/192.168.1.59: _media_ssd__raid10_ovirt_data__fast/f617dfce-4ac8-495b-a0f3-4f85ce39df27/ha_agent/hosted-engine.metadata' My storage machine is a separate host running RHEL 6.4. /etc/exports looks like this: /media/ssd_raid10/ *(rw,sync,all_squash) /media/ssd_raid10/ovirt *(rw,sync,no_subtree_check,anonuid=36,anongid=36,all_squash) *some other shares* Now here is the strange part: after repeatedly bashing my head against the wall I finally noticed the difference: on the first host it mounts as: 192.168.1.59:/media/ssd_raid10/ovirt/data_fast on /rhev/data-center/mnt/192.168.1.59:_media_ssd__raid10_ovirt_data__fast_ While on the second host it mounts as: 192.168.1.59:/media/ssd_raid10/ovirt/data_fast on /rhev/data-center/mnt/192.168.1.59:_media_ssd__raid10_ovirt_data__fast (note the lack of underscore in the end) That is what caused the problem - this "hosted-engine.metadata" file is actually a symlink. And because of different mount points on the second host it was pointing to nowhere. So I figured, maybe I should add / to the end of the nfs path. So I tried it like this: Please specify the storage you would like to use (iscsi, nfs3, nfs4)[nfs3]: Please specify the full shared storage connection path to use (example: host:/path): 192.168.1.59:/media/ssd_raid10/ovirt/data_fast/ [ INFO ] Installing on first host Please provide storage domain name. [hosted_storage]: As you can see, in this case it doesn't detect that it already has a hosted engine installed. So, I'm out of ideas how to make it work. There is clearly something unstable in the installation scripts, but does anyone have any idea how to make it work? PS: Sorry for my crude English, not really a native speaker. Thanks, Tigran.
