Impact of changing VLAN of ovirtmgmt in the Data Center?
by Garry Tiedemann 14 Mar '16

14 Mar '16

Hi everyone, In Data Centers > (Name) > Networks section of the Ovirt GUI, network definitions include the VLAN IDs. In my case, the VLAN ID of ovirtmgmt has been empty (meaning VLAN 1) since I built it; it's always been wrong. My hypervisor hosts' ovirtmgmt bridges are actually in VLAN 20. An error message alerted me to this mismatch a few days ago. None of my production VMs are on VLAN 1, or VLAN 20, but I'd like to confirm if it's safe to change this. Can changing the VLAN ID of ovirtmgmt within Data Center > Networks impact VMs from other VLANs? I see no reason why it should be a problem. We just need some certainty on that point. Thankyou in advance for answers. Regards, Garry PS This is a briefer and clearer re-statement of the question I asked a couple of days ago.

[hosted-engine] install additional nodes without knowing another HE host's root password?
by Wee Sritippho 14 Mar '16

14 Mar '16

Hi, I'm trying to deploy a 2nd host to my hosted-engine environment, but the 1st host doesn't have a root password - it only has a sudo account. I can temporarily set a password and enable ssh for the root account, but I'm curious whether there is proper way to do this without messing with the user accounts? for example: - Locating the answer file that was copied from the 1st host manually (I already tried 'hosted-engine --deploy --config-append=answers-XXXXXXXXXXXXXX.conf' but the setup thought that I'm going to deploy my 1st host) - scp from an account other than 'root' Regards, Wee --- ซอฟต์แวร์ Avast แอนตี้ไวรัสตรวจสอบหาไวรัสจากอีเมลนี้แล้ว https://www.avast.com/antivirus

New install of hosted-engine using FibreChannel storage presenting Errors
by Paxton, Darren 13 Mar '16

13 Mar '16

Hi all Set up a brand new cluster with hosted-engine. Chose Fibre-Channel as the storage mechanism however on completion, running hosted-engine -vm-status I get the following; # hosted-engine --vm-status Traceback (most recent call last): File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main "__main__", fname, loader, pkg_name) File "/usr/lib64/python2.7/runpy.py", line 72, in _run_code exec code in run_globals File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_setup/vm_status.py", line 117, in <module> if not status_checker.print_status(): File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_setup/vm_status.py", line 60, in print_status all_host_stats = ha_cli.get_all_host_stats() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 160, in get_all_host_stats return self.get_all_stats(self.StatModes.HOST) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 107, in get_all_stats stats = self._parse_stats(stats, mode) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 146, in _parse_stats md = metadata.parse_metadata_to_dict(host_id, data) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/metadata.py", line 156, in parse_metadata_to_dict constants.METADATA_FEATURE_VERSION)) ovirt_hosted_engine_ha.lib.exceptions.FatalMetadataError: Metadata version 5 from host 20 too new for this agent (highest compatible version: 1) This also results in adding a 2nd host failing due to a similar problem. I saw a previous post regarding iscsi storage resulting in similar errors but not FibreChannel. I can provide engine logs and such like if someone can guide me to what exact files to provide. I had cleared down the fibre-chaannel storage but do I need to wipe the devices fully before trying again? Thanks Darren

"wildcard resolve to multiple address" during hosted-engine --deploy
by Zach 13 Mar '16

13 Mar '16

I keep running into the following error when going through the "hosted-engine --deploy" configuration. [ ERROR ] Failed to execute stage 'Setup validation': wildcard resolved to multiple address So far, I haven't been able to figure out what I'm doing wrong. My best guess is that there is some issue with the FQDN that I used, but I'm not sure what I've done wrong. I've included the following line in /etc/hosts for the FQDN. 192.168.0.50 ovirt.domain.local I've also attached the output log, as well as the full output of me answering all the prompts. Any help would be appreciated, let me know if I need to include more information.

Know the console client IP from guest
by Simon Lévesuqe 13 Mar '16

13 Mar '16

From a windows guest (can be useful for linux guest as well), is it possible to get the IP of the spice client connected to console? I setup oVirt for a VDI. The users use thin clients that PXE boot using LTSP. I need the client IP to offer remote support via VNC. Now, I use epoptes as remote support tool, its an excellent peace of software but I need technicians from other branch of the company to be able to offer remote support to my users and they are all Windows guy ans don't want to connect to the LTSP server to start epoptes... They already use VNC to support Wyse type clients so I installed x11vnc on my clients chroot and setup it to start at boot. I know this is a security issue but this is the boss decision. Some client log to terminal servers using xfreerdp (LTSP clients boot directly to xfreerdp). In that case, everything is ok, we setup bginfo to print the client name and ip as they are windows environment variables. The problem is that many other clients boot to the oVirt user portal and users log to Windows 7 vm using Virt-Viewer and Spice. In bginfo, the only thing i can get is the IP of the Windows guest. It's ok, for most cases we can take control of the guest ant it do the trick but sometimes it's useful to vnc the thin itself. Thanks! Simon L

spacewalk integration
by Charles Kozler 13 Mar '16

13 Mar '16

Hi Guys - Can you use spacewalk as an external provider in oVirt? I see it allows Satelilte/Foreman but I know the new Satellite product is much different than Spacewalk as I believe Spacewalk is still technically Satellite 5 whereas Satellite 6 is an entire rewrite If Spacewalk can be used, what are some pre-reqs needed to get it working? Also, what are the benefits of using this? I was looking at it for the eratta information Thanks! -- *Charles Kozler* *Vice President, IT Operations* FIX Flyer, LLC 225 Broadway | Suite 1600 | New York, NY 10007 1-888-349-3593 http://www.fixflyer.com <http://fixflyer.com> NOTICE TO RECIPIENT: THIS E-MAIL IS MEANT ONLY FOR THE INTENDED RECIPIENT(S) OF THE TRANSMISSION, AND CONTAINS CONFIDENTIAL INFORMATION WHICH IS PROPRIETARY TO FIX FLYER LLC.

el6 and el7 clusters and SPM
by Sigbjorn Lie 13 Mar '16

13 Mar '16

Hi I am looking to migrate several el6 rhev-h nodes to el7 rhev-h nodes. There are multiple clusters in the datacenter and it will take a while (several months) to have all the clusters in the data center migrated to el7. Is there be any potential issues to look out for with regards to having the SPM for this datacenter running on a el6 or a el7 node in this datacenter? Any cross compatability issues to look out for? RHEV-M is currently at version 3.5.6. We are using FC storage. Regards, Siggi

QEMU GlusterFS support in oVirt
by Samuli Heinonen 13 Mar '16

13 Mar '16

Hello all, It seems that oVirt 3.6 is still using FUSE to access GlusterFS storage domains instead of using QEMU driver (libgfapi). As far as I know libgfapi support should be available in Libvirt and QEMU packages provided in CentOS 7. Is there any workarounds how to use libgfapi with oVirt before it’s officially available? Best regards, Samuli Heinonen
