can't run VM
by garcialiang.anne＠gmail.com 27 Mar '20

27 Mar '20

Hi, I created VM on ovirt-engine. But I can't run this VM. The message is : 2020-03-26 21:28:02,745+01 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-147) [] EVENT_ID: USER_FAILED_RUN_VM(54), Failed to run VM VirtMachine due to a failed validation: [Cannot run VM. There is no host that satisfies current scheduling constraints. See below for details:, The host xxxxxxxxx did not satisfy internal filter Network because display network ovirtmgmt was missing.] (User: admin@internal-authz). Could you help me ? Thanks Anne

Orphaned ISO Storage Domain
by bob.franzke＠mdaemon.com 26 Mar '20

26 Mar '20

Greetings all, Full disclosure, complete OVIRT novice here. I inherited an OVIRT system and had a complete ovirt-engine back in December-January. Because of time and my inexperience with OVIRT, I had to resort to hiring consultants to rebuild my OVIRT engine from backups. That’s a situation I never want to repeat. Anyway, we were able to piece it together and at least get most functionality back. The previous setup had a ISO storage domain called ‘ISO-COLO’ that seems to have been hosted on the engine server itself. The engine hostname is ‘mydesktop’. We restored the engine from backups I had taken of the SQL DB and various support files using the built in OVIRT backup tool. So now when looking into the OVIRT console, I see the storage domain listed. It has a status of ‘inactive’ showing in the list of various storage domains we have setup for this. We tried to ‘activate’ it and it fails activation. The path listed for the domain is mydesktop:/gluster/colo-iso. On the host however there is no mountpoint that equates to that path: [root@mydesktop ~]# df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 47G 0 47G 0% /dev tmpfs 47G 12K 47G 1% /dev/shm tmpfs 47G 131M 47G 1% /run tmpfs 47G 0 47G 0% /sys/fs/cgroup /dev/mapper/centos-root 50G 5.4G 45G 11% / /dev/sda2 1014M 185M 830M 19% /boot /dev/sda1 200M 12M 189M 6% /boot/efi /dev/mapper/centos-home 224G 15G 210G 7% /home tmpfs 9.3G 0 9.3G 0% /run/user/0 The original layout looked like this on the broken engine: [root@mydesktop ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/centos_mydesktop-root 50G 27G 20G 58% / devtmpfs 24G 0 24G 0% /dev tmpfs 24G 28K 24G 1% /dev/shm tmpfs 24G 42M 24G 1% /run tmpfs 24G 0 24G 0% /sys/fs/cgroup /dev/mapper/centos_mydesktop-home 25G 45M 24G 1% /home /dev/sdc1 1014M 307M 708M 31% /boot /dev/mapper/centos_mydesktop-gluster 177G 127G 42G 76% /gluster tmpfs 4.7G 0 4.7G 0% /run/user/0 So it seems the orphaned storage domain is just point to a path that does not exist on the new Engine host. Also noticed some of the hosts are trying to aces this storage domain and getting errors: The error message for connection mydesktop:/gluster/colo-iso returned by VDSM was: Problem while trying to mount target 3/17/2010:47:05 AM Failed to connect Host vm-host-colo-2 to the Storage Domains ISO-Colo. 3/17/2010:47:05 AM So it seems hosts are trying to be connected to this storage domain but cannot because its not there. Any of the files from the original path are not available so I am not even sure what we are missing if anything. So what are my options here. Destroy the current ISO domain and recreate it, or somehow provide the correct path on the engine server? Currently the storage space I can use is mounted with /home, which is a different path than the original one. Not sure if anything can be done with the disk layout at this point to correct this on the engine server itself to get the gluster path back. Right now we cannot attach CDs to VMs for booting. No choices show up for use when doing a ‘run once’ on an existing VM so I would like to get this working so I can fix a broken VM that I need to boot off of ISO media. Thanks in advance for any help you can provide.

how to use idrac interface as a vm network
by Nathanaël Blanchet 25 Mar '20

25 Mar '20

Hello, I noticed an idrac interface was available in the host network since an undefined ovirt version. Mine are already plugged as dedicated vlan to administrate host at the lowest level. I tested to use it as a vm network on the same vlan, but it doesn't work. What am I supposed to do with this available interface? PS: on HP hosts, no Ilo interface appears in host network tab -- Nathanaël Blanchet Supervision réseau SIRE 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

That may be true, but in the ISO domain, when you open virt viewer you can change the cd very easily...maybe it works that way as well..

Migrate Hosted Engine to new Storage
by Anton Louw 25 Mar '20

25 Mar '20

Hi Everybody, Does anybody know when we will most likely be able to do a live storage migration of the Hosted Engine? I've been battling with the backup and restore way for a couple of days now already, and it is starting to feel like a fruitless exercise. Thanks Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za
