Ovirt 3.5 / CentOS 7 / GlusterFS - Host loses network config on reboot
by Tim Macy 20 Jan '15

20 Jan '15

I have a three node cluster that worked fine upon setup, but randomly (Its happened three times now) when a host is rebooted it loses its network config. I backed up the ifcfg*, route, and rule* files to quickly put things back in place, but even then vdsm fails to start and host reinstall from the engine errors on vdsm startup. The only way that I have found to recover the node is yum remove vdsm* libvirt*, and rm -Rf /etc/vdsm & /var/lib/vdsm. Then I can run host reinstall from the engine. Where the error occurs in host-deploy log: 2015-01-20 01:21:58 DEBUG otopi.plugins.otopi.services.systemd plugin.execute:866 execute-output: ('/bin/systemctl', 'start', 'vdsmd.service') stderr: Job for vdsmd.service failed.

Hi, all I later found a msi about "USBFilterEditor.msi" As the guide http://www.uaustral.cl/ovirt-engine/docs/manual/en_US/html/Administration_G… I use my own usbfilter.txt to replace the /etc/ovirt-engine/usbfilter.txt in the rhevm host.

When will ovirt add GPU/vGPU support in the admin portal ?

Since I recently saw cloudstack have add this( https://cwiki.apache.org/confluence/display/CLOUDSTACK/GPU+and+vGPU+support… ). And iGVT( https://01.org/zh/xen/blogs/wangbo85/2014/intel-gvt-gxengt-pubic-release?la…) is released. If ovirt add this, it'll be very competitive for ovirt in VDI platforms.

ovirt 3.5 and power outages
by Kostyrev Aleksandr 19 Jan '15

19 Jan '15

good day, everybody! I've got three node cluster with power management enabled. As far as I understood to restart vms on the other host in the cluster in case when host suffered from power outage the engine has to be able to connect to host (specifically to vdsm) to be sure that host has been rebooted and it's not running any vms. But what if I'm running a lot of vms on the host and it's 3 o'clock in the morning and 1) engine has rebooted the host but the host cannot boot because of some hardware problem or new kernel gives a kernel panic? 2) the host's motherboard burned out and it cannot get booted so the engine will never connect to host and therefore all the vms that were running on that host won't migrate to other node in the cluster. So my cluster in that case is useless 'cause I'm not there to press "confirm host has been rebooted'. -- С уважением, Костырев Александр, системный администратор
