changing IP addresses
by Ben De Luca 12 Feb '17

Hi, I have a client who wants to change the IP's of an ovirt cluster running hosted engine. Is there a guide to do this? or would it be simpler to rebuild the cluster and migrate the machines? -Ben

Hello, yesterday I saw this message 3 times Add VM NUMA node successfully. and it seems to me that it was at the same time when I edited some VMs and in Console --> Advance parameters I set "disable strict user checking" Are they indeed related? What is the relation with NUMA? Thanks, Gianluca

Hosted Engine migration problems
by Jim Kusznir 12 Feb '17

12 Feb '17

Hi again: I thought I had fixed the hosted engine migration that was preventing me from updating the host the engine was running on. Today it let me migrate it from ovirt1 to ovirt2, and perform needed updates on ovirt1. When I tried to migrate it back to ovirt1 after the updates, I got errors that it failed migration. I tried an auto-migrate, and it claimed that the other two nodes (including the node it was running on) do not meet minimum requrements, specifically that they are not HA nodes....But I did explicitly set them up as HA nodes. Here's the engine.log output from the command: 2017-02-11 06:12:03,078 INFO [org.ovirt.engine.core.bll.scheduling.SchedulingManager] (default task-41) [252e1f97] Candidate host 'engine1' ('1e182fb9-8057-42ed-abd6-bc5bc343ccc6') was filtered out by 'VAR__FILTERTYPE__INTERNAL' filter 'HA' (correlation id: null) 2017-02-11 06:12:03,078 INFO [org.ovirt.engine.core.bll.scheduling.SchedulingManager] (default task-41) [252e1f97] Candidate host 'engine3' ('bac8ace2-cf7e-48ea-9113-b82343cd87f7') was filtered out by 'VAR__FILTERTYPE__INTERNAL' filter 'HA' (correlation id: null) 2017-02-11 06:12:03,081 INFO [org.ovirt.engine.core.bll.scheduling.SchedulingManager] (default task-41) [252e1f97] Candidate host 'engine2' ('76c075fc-1dfb-479d-98ef-57575ec11787') was filtered out by 'VAR__FILTERTYPE__INTERNAL' filter 'Migration' (correlation id: null) 2017-02-11 06:12:03,081 WARN [org.ovirt.engine.core.bll.MigrateVmCommand] (default task-41) [252e1f97] Validation of action 'MigrateVm' failed for user admin@internal-authz.

Network issues
by Bryan Sockel 11 Feb '17

11 Feb '17

Need some help. I was doing some work on one of my ovirt hosts, removed it from cluster, and re-added it to the cluster to bring it back into my working cluster. I got a messege that my network's where out of sync. I accidentally sync'd up my working network, now neither of my hosts will bring launch my hosted engine appliance. While machines aren't currently mission critical, i do need to get these machines backup up and running. The network configuration is supposed to be 6 nics forming a bond network, my vlan's hanging off that bond, including my ovirtmgmt network.

Gluster storage question
by Bartosiak-Jentys, Chris 11 Feb '17

11 Feb '17

Hello list, Just wanted to get your opinion on my ovirt home lab setup. While this is not a production setup I would like it to run relatively reliably so please tell me if the following storage configuration is likely to result in corruption or just bat s**t insane. I have a 3 node hosted engine setup, VM data store and engine data store are both replica 3 gluster volumes (one brick on each host). I do not want to run all 3 hosts 24/7 due to electricity costs, I only power up the larger hosts (2 Dell R710's) when I need additional resources for VM's. I read about using CTDB and floating/virtual IP's to allow the storage mount point to transition between available hosts but after some thought decided to go about this another, simpler, way: I created a common hostname for the storage mount points: gfs-data and gfs-engine On each host I edited /etc/hosts file to have these hostnames resolve to each hosts IP i.e. on host1 gfs-data & gfs-engine --> host1 IP on host2 gfs-data & gfs-engine --> host2 IP etc. In ovirt engine each storage domain is mounted as gfs-data:/data and gfs-engine:/engine My thinking is that this way no matter which host is up and acting as SPM it will be able to mount the storage as its only dependent on that host being up. I changed gluster options for server-quorum-ratio so that the volumes remain up even if quorum is not met, I know this is risky but its just a lab setup after all. So, any thoughts on the /etc/hosts method to ensure the storage mount point is always available? Is data corruption more or less inevitable with this setup? Am I insane ;) ? Thanks,

Trying oVirt 4.1
by Andy Michielsen 11 Feb '17

11 Feb '17

Hello all, I was trying to give the latest oVirt a go and install it on my KVM system before committing it on any hardware. The installation went fine. When logging on into the node https://<node>:9090 I wanted to install an hosted engine but I get this messages Failed to execute stage 'Environment setup': [Errno 2] No such file or directory: '/etc/iscsi/initiatorname.iscsi' Hosted Engine deployment failed But I must admit I have not set up iscsi nor do I want to. Maybe local, nfs or glusterfs. What is the way to do this properly ? Kind regards.

Optimizations for VoIP VM
by Jim Kusznir 11 Feb '17

11 Feb '17

Hello: I set up a FreeSwitch-based VoIP server as a host on my cluster, and am having audio problems. I'm not 100% sure if its virtualization related or network related yet. But I would like to optimize my VM for VoIP (or rather, tell Ovirt all the "right settings" to optimize that VM to VoIP). Does anyone have any specific suggestions? Are there known issues with VoIP on Ovirt-managed clusters? (I know well reputed companies that sell VoIP server virtual hosting and guarantee the performance, so I know VoIP Virtualization is possible, just need to know if its recommended with Ovirt, and if so what do I need to do to give it the best chance of success?) Thanks! --Jim

oVirt maintence "best practices"
by Jim Kusznir 10 Feb '17

10 Feb '17

hello: Now that I've had my ovirt cluster running for about a month and a half, I am realizing I don't necessarily know the best practices for keeping it up. I've been seeing the notices in the ovirt hosts screen showing that there are updates waiting for the hosts, and I'll put them in maintence mode one at a time and apply the updates. What about the engine itself? Is it recommended/safe to log into the engine and just run "yum update"? Is there other procedures I should be doing? My oVirt cluster is a 3 node cluster with gluster, running on each node. Thanks! --Jim
