Hi Sven, Regarding the ticket "path", Is it the direct combination of host and port ? suppose if the host is 1.2.3.4 and the port is 5100 then what should be the "path" value ? Is there encryption needs here ? >>so you have access from the browser to the websocket-proxy, network wise? can you ping the proxy? and the websocket proxy can reach the host where the vm runs? yes.. there should be no firewall issue as we can access the console from ovirt engine portal Do we need to allow our own portal ip address in the ovirt engine and hypervisiors also ??? -- Regards Shanil On Wed, Jul 16, 2014 at 3:13 PM, Sven Kieske <S.Kieske(a)mittwald.de> wrote: > > > Am 16.07.2014 11:30, schrieb Shanil S: > > We will get the ticket details like host,port and password from the > ticket > > api funcion call but didn't get the "path" value.

backup.sh fails
by Niklas Fondberg 04 Aug '14

04 Aug '14

Hi all, I might be of a tangent but I tried to follow the steps in http://www.ovirt.org/User_talk:Stkeimond/Backing_Up_And_Restoring_OVirt for a backup. I get an error because of the postgres user password that I never set in the installation of oVirt (as far as I know.) Does anyone know of another way to backup or is this a bug/fault_by_me? The command line and error is: [root@dl380 dbscripts]# ./backup.sh -u postgres -l /mnt/msa60/backups/ Backup of database engine to /mnt/msa60/backups//engine_Mon_Jul_14_16:50:45_CEST_2014.sql started... pg_dump: [archiver (db)] connection to database "engine" failed: FATAL: Ident authentication failed for user "postgres" pg_dump: *** aborted because of error Backup of database engine failed.

Lowering cluster CPU level : safe?
by Nicolas Ecarnot 04 Aug '14

04 Aug '14

Hi, I'm trying to add some Westmere hosts into a Sandybridge cluster, and of course, they get refused : "Host xxxxxxxxx moved to Non-Operational state as host does not meet the cluster's minimum CPU level. Missing CPU features : model_SandyBridge" I tried to lower the cluster level but I get this warning : "Change Cluster CPU level There are running VMs. Lowering the Cluster CPU level might prevent migration of these VMs to some of the Hosts in the Cluster. Are you sure you want to continue?" As a frightened chicken, I clicked "Cancel" and turned to you : how safe is it to lower the CPU level? I understand some instructions will be missing, and maybe performance will change, but we don't have heavy CPU usage yet, so this may not be a big issue. I was wondering what will happen to my existing VMs? Will I have to modify some setup? What may prevent migration between westmere and sandybridge hosts? Regards, -- Nicolas Ecarnot

RAID Expanded
by Neil 04 Aug '14

04 Aug '14

Hi guys, I'm running oVirt 3.3 with an FC SAN. I had 12x500GB LUNS and these were all assigned to my data domain. Once the new volumes have finally finished syncing on the SAN, will oVirt automatically see the new LUNS, or is there anything that needs to be done in order to see them? I'm just trying to prepare for when things finally finish. Thank you. Regards. Neil Wilson.

ilo4 vs. ipmilan fencing agents
by Jason Brooks 04 Aug '14

04 Aug '14

Hi all -- I'm trying to get fencing squared away in my cluster of hp dl-380 servers, which come with ilo4. I was able to get a successful status check from the command line with fence_ilo4, but not w/ the ilo4 option in ovirt. I see, though, that ilo4 in ovirt just maps to fence_ipmilan, and I was not able to get a successful status check w/ fence_ipmilan from the cli. So, I tried resetting the mapping so that ilo4 maps to ilo4. Now I can complete the power management test in ovirt, but I imagine there's some reason why ovirt isn't configured this way by default. Will fencing actually work for me with ilo4 mapped to ilo4, rather than to ipmilan? Thanks, Jason --- Jason Brooks Red Hat Open Source and Standards @jasonbrooks | @redhatopen http://community.redhat.com
