Automatically migrate VM between hosts in the same cluster
by Luca Bertoncello 18 Sep '15

18 Sep '15

Hi list! I'm new by oVirt. Right now I configured a Cluster with two hosts and a VM. I can migrate the VM between the two hosts without any problem, but what I need is, that the VM automatically migrate if an host is down. The migration occurs just if I set an host in "Maintenance", but this is not (only!) what I need... Can someone help me to configure oVirt (3.5) to automatically check the hosts and migrate the VM on host failure? Thanks a lot!

Storage and ISO Domain and Engine VM
by Richard Neuboeck 18 Sep '15

18 Sep '15

This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --8DQ1estunpO0IIDrhSg9sVKrbFlJwL1AS Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hi oVirt Team, I'm trying to set up oVirt 3.6 on three virtualization hosts connected to two other machines solely providing a replica 2 gluster storage. I know and understand that this setup is basically unwise and not supported but to prevent the gluster storage from going off line I followed the suggestion in https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3/html/Admi= nistration_Guide/sect-Managing_Split-brain.html 8.10.1.1 and added a dummy node with no bricks. Removing the requirement for replica 3 in nfs.py and allowing replica count 2 in vdsm.conf makes the installation possible without error. But at the first login on the web UI the only thing showing that's configured during the installation process is the virtualization host. The Engine VM is not listed in the Virtual Machines tab though the hosts shows one running VM. After watching several youtube videos from self hosed engine installations I'm guessing the Engine VM should be visible. Is there anything I can do? The Storage tab is completely empty. The ISO Domain that is configured during the install is not shown. As well as the gluster storage that is storing the Engine VM. I've heard in this video from Martin Sivak https://www.youtube.com/watch?v=3DEbRdUPVlxyQ that the storage domain where the Engine is stored is hidden. Why is that? So if the Engine storage is separated from the other VMs storage there should be two gluster volumes for VM storage if the self hosted setup is used? Why is the ISO Domain not shown? Since I'm (still) an oVirt newbie I'm guessing something has gone wrong during the installation or I'm missing some piece of the puzzle. So here are more details: - The gluster hosts are running an up date CentOS 7.1, Gluster 3.7. The volume where the Engine is stored has the recommended optimizations as described in http://www.ovirt.org/Features/GlusterFS_Storage_Domain - The self hosted engine deployment install is running on a minimal CentOS 7.1 (up to date). http://www.ovirt.org/Hosted_Engine_Howto#Fresh_Install - The repo from which oVirt is coming: http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm - I modified /usr/share/ovirt-hosted-engine-setup/plugins/ovirt-hosted-engine-setup/st= orage/nfs.py and substituted the replica 3 requirements appropriately for replica 2 - and added allowed_replica_counts =3D 1,2,3 in /etc/vdsm/vdsm.conf - hosted-engine --deploy runs without errors. Except for 'balloonInfo' errors vdsm.log doesn't show any (obvious) errors either. - The engine setup in the VM (CentOS 7.1 again) runs without problems as well. - After the install has finished the Engine is _not_ run automatically. After waiting some minutes I've started it running hosted-engine --vm-start. So far I've wiped everything clean and tried to install oVirt 3.6 twice and twice it was the same result so I'm not sure how to proceed. Any suggestions on what may have gone wrong or what I've missed to do?

Daily online VM backups
by gregor 17 Sep '15

17 Sep '15

Hi, what is the best way to make daily backups of my VM's without shutting them down? I found the Backup-Restore API and other stuff but no running tool/script which I can use. I plan to integrate it into backuppc. Or is there any "Best practice guide for backup"? ;-) In the meantime I integrated engine-backup into backuppc as a pre-script. cheers gregor

P2V shrink disk
by wodel youchi 17 Sep '15

17 Sep '15

Hi, I am not sure if it's the right place to post this question. I tried to do a P2V operation of a Win2k3 server to ovirt 3.5 the physical server is RAID5 of 3x146Go configured, about 290 Go usable space, but the server uses about 20Go only. I am wondering how to shrink the disk of the migrated physical machine, do I have to do it before using P2V tool? The same question for Linux servers. Thanks.

Network statistics shown in ovirt doesn't look correct.
by Ramesh Nachimuthu 16 Sep '15

16 Sep '15

Hi, I have a strange issue with the network traffic shown in oVirt webadmin portal. I have 2 10 Gb network card and I have created bond out of them. I have used *'iperf*' command to generate10 Gbps traffic and I can see that getting reflected in my nagios monitoring. Also iperf command confirms that it transferred the data at the rate of 9.38 Gbits/sec. But oVirt Ui shows only 1500 Mbps. I am not sure how oVirt shows very low traffic. Anyone experiencing the similar problem? VDSM Version: vdsm-4.16.20-1.3.el6rhs.x86_64 Ovirt release : both 3.5 and 3.6 I have attached the relevant screen shots here. Regards, Ramesh
