Replacing Export Domain by Data Domain
by tehnic＠take3.ro
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
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.

Hello Guys
I install 6 host with Ovirt 4.2 connected via FC to Brocade 300 switch and HP EVA P2000 Storage.
Zoning was performed on each SAN switch and when creating a Virtual Disk with 3 LUN, but adding the Storage in OVIRT does not see any LUN. 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.

oVirt Node 4.2.5.1 vm stuck on "Powering Down"
by maoz zadok
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
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
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

Acquire an XML dump of a VM oVirt?
by Jacob Green
How does one get an XML dump of a VM from ovirt? I have seen ovirt
do it in the engine.log, but not sure how to force it to generate one
when I need it.
Thank you.
