Which option is best for storage?
by geoff＠pdclouds.com.au 04 Jan '19

Hi, Which is the preferred option for connecting oVirt VM farm to SAN/NAS? NFS (10G), iSCSI (10G) or FC (8G)? We are confused, some people say iSCSI is preferred and others say NFS performs the better than iSCSI, but FC is most expensive but performs the best overall.... Would value expert opinion. Cheers Geoff

Unable to increase memory or CPU on hosted Engine version 4.2.5.2
by Florian Schmid 04 Jan '19

04 Jan '19

Hi, I'm using version 4.2.5.2 and every article I found, I read that with oVirt 4.2, it should be possible to update CPU and memory for hosted Engine in UI. Now, when I'm trying to do this, even being on global maintenance, I always get the same error: Error while executing action: HostedEngine: There was an attempt to change Hosted Engine VM values that are locked. My problem is, that I need to increase the memory, because we had now several times in the last 2 or 3 months an out of memory kill of the java process. What is the best way to increase memory here? Should I do it over the config file? But how is then the OVF updated? BR Florian

Replacing Export Domain by Data Domain
by tehnic＠take3.ro 03 Jan '19

03 Jan '19

Hello all, because using an export domain is deprecated i deleted my export domain and use now a data domain instead. I used the export domain for complete image backups of my production virtual machines. By using now a data domain its even more comfortable because i can clone a snapshot directly on my backup data domain. But there is a (small?) inconvenience: I cannot "unregister" the cloned snapshot and i dont want to see them all the time in the "Virtual Machines" list. For the moment i use a bookmark in the "Vms:" filter. After detaching the domain the VMs are away, reattaching brings them back for possible "Import VM". Is there a possibility to set the cloned VM directly to this "unregistered" state without detaching and reattaching the complete domain? Best regards, Robert

Information about un-imported VMs. Delete Request.
by Jacob Green 03 Jan '19

03 Jan '19

I have a Fiber Channel domain, it works, there are some VMs in the VM import tab of the domain that I want to remove, I cannot import them, because they technically already exsist with a duplicate VMID. Is there a way to do this? Alternatively if I cannot delete the data related the the imports, I want to remove the disks attached to these un-imported VM's to free up space on my Fiber Channel, is there a way to reliably identify which LVM id's belong to those un-imported VMs? Thank you. -- Jacob Green Systems Admin American Alloy Steel 713-300-5690

oVirt Node 4.2.5.1 vm stuck on "Powering Down"
by maoz zadok 03 Jan '19

03 Jan '19

Hello, vm stuck (on two hosts) I have MySQL VM guest that was stuck in a way that "kill -9" to the MySQL server pid did nothing. from the shell I execute "init 0", this did not shut down the VM. from the ovirt-engine I'm trying to power off the machine, and it is not doing anything. the event shows: > VDSM kvm5 command DestroyVDS failed: Virtual machine destroy error > and: > Failed to power off VM mysql-production (Host: kvm5, User: > admin@internal-authz). > Note, when I list the VM s on the hosts view, I see that that same VM is on two hosts (kvm7 and kvm5). It looks like the VM is stuck on two hosts, in the status "Powering Down" any ideas? Thank you

GlusterFS Storage - Size limited at 2 GB
by v.levet＠isiline.net 03 Jan '19

03 Jan '19

Hello everyone, I've installed oVirt on 8 nodes of a MacroServer (SuperMicro Microcloud): 7 Nodes with oVirt Node installed and 1 Node with Centos 7 and oVirt installed. The last one works like hypervisor and node. I would use all the storage of all nodes like a Gluster storage, so I've created a new DataCenter, with a Cluster with all nodes inside. Then I've created the volume Gluster (by GUI): Replicated Duplicated version and 4 replicas on all 8 nodes. Than "Optimize for oVirt Storage". For last I've created Domain storage based on volume created before. All works fine but the total storage that is available from Domain is 1.9 GB. I've tried already to force it using these commands: gluster volume GlusterVol limit-usage / 3200GB gluster volume quota GlusterVol limit-usage /data 3200GB At first it seems work but finally when I was installing a VM, I get Full Storage. It seems that it could use only the storage of the node where is instantiated the volume. I would see all the storage distributed and I wish I could use the storage from all nodes. Someone could help me?

Vm console direct connection
by Leo David 03 Jan '19

Hello everyone, Could someone be so kind to tell me if there's any chance that virt-viewer or any other client can be used to directly connect to vms running on oVirt without the need for the user to access the portal first ? Thank you very much ! Cheers, Leo

Hello Guys I install 6 host with Ovirt 4.2 connected via FC to Brocade 300 switch and HP EVA P2000 Storage.

The OVIRT nodes were restarted, the Engine but still does not see the LUNs I have searched for information on how to resolve this issue but I have not had any information.
