Do you have any idea if SBD fencing mechanism will be implemented in the nearest future?
It will be nice to be able to resset a host just like corosync/pacemaker cluster implementation.
Ok, so I want to try and more thoroughly explain my situation. I
want to better understand what is happening, and if there is a way to
force import over the faster connection.
Today I have two Ovirt environments, one on 4.1 and one on 4.2, on
the new environment we have migrated to new VLANs for Management and Data.
The export domain is a NFS domain hosted on a Trunas device that
has an ip address of X.X.12.100.
Our host has multiple Ethernet connections, one Bonded 20Gigabit
interface. That is where we have the ovirtmgmt profile. And a secondary
1 Gigabit interface that we call our VLAN12 profile or server VLAN.
*The problem.... *When importing a VM from the export domain, the import
is happening over the 1Gigabit interface on the VLAN12 profile. Instead
of the 20gigabit Bonded interface on VLAN 100.
*My understanding.... *So I probably just misunderstand how this works,
but here is what I thought should happen, in the *Setup Host Network*
screen for this host I have the ovirtmgmt on VLAN100 with the bonded
20Gigabit interface performing the following. "*Management, Display,
Migration, VM and Default Route*." Then I have the secondary 1 Gigabit
interface just doing "*VM*" on VLAN12. What I thought should happen is
that anything Migration related "*/Includes importing from export
domain?/*" should happen on the Migration interface, which in my case is
the ovritmgmt interface on VLAN100.
I have also confirmed that I can ping from the VLAN100 ovirtmgmt
interface to the storage on VLAN12. So there is connectivity from that
interface to the storage. What I am trying to figure out is there a way
to force it to do imports over the 20Gigabit interface that resides on
VLAN100 instead of the slower VLAN12 interface, that is just there for
general VM connectivity.
Thank you for any advice or guidance on this matter.

I'm on oVirt 4.2.6.
1) If I have a Tesla P4 (Pascal) GPU (non-GRID), do I use nVidia vGPU driver for RHEL KVM 6.2 or the Linux KVM vGPU 6.2 driver?
2) If I have a Grid K1 or K2, I assume the correct driver would be GRID 4.7?
3) Must the vGPU driver be installed on the host & in the vm?
4) Must the vGPU driver be installed first before I can run "yum -y install vdsm-hook-vfio-mdev”
4.3 Master is looking good!!
A few questions:
- In Step #2: Fqdns: for a 3 host cluster, are we to add the 2nd & 3rd
- In Step #5: Bricks:
What effect does the RAID setting have?
Enable Dedupe & Compression is new?
Configure LV Cache: what do we enter for SSD? What happens if my disks
are already all SSD, do I still benefit from using this?

As part of our efforts to raise awareness of and educate more developers
about the oVirt project, we will be holding an oVirt workshop at
LinuxCon Japan, taking place on June 8, 2012. You can find full details
of the workshop agenda on the LinuxCon Japan site. 
Registration for the workshop is now open and is free of charge for the
first 50 participants. We will also look at adding additional
participant slots to the workshop based on demand.
Attendees who register for LinuxCon Japan via the workshop registration
link  will also be eligible for a discount on their LinuxCon Japan
Please spread the word to folks you think would find the workshop
useful. If they have already registered for LinuxCon Japan, they can
simply edit their existing registration to include the workshop.

The "hugepages" custom property value in oVirt should be set to *size of
the pages in KiB* (i.e. 1GiB = 1048576, 2MiB = 2048).
In addition, it is recommended to set the huge page size of the VM to the
largest size supported by the host.
In the configuration you sent, the huge page size of the VM is set to 64
KiB and since the VM's allocated memory size is at least 32,768 MiB then it
requires at least (32768 * 1024/64=) 524,288 pages. Since you only have 120
pages declared in the host then it failed with an error "...there are not
enough free huge pages to run the VM".
So to solve the problem, please change the VM's huge page size to be the
same as the host's huge page supported size which is 1GiB and therefore
hugepages value should be 1048576 KiB instead of 64:
Please note that since total VM's memory size is no more than 64 GB then
only 64 pages will be needed by the VM and it's < 120 pages supported by
the host and therefore OK.
Hope it helped.

it's me again....
I started my oVirt 'project' as a proof of concept,.. but it happend as always, it became production
Now, I've to move the iSCSI Master data to the real iSCSI traget.
Is there any way to do this, and to become rid of the old Master Data?
Thank you for your help

We are integrating ovirt with our internal cloud.
Here we installed cloudinit in vm and then converted vm to template. We
deploy template with initial run parameter Hostname, IP Address, Gateway
but when we power ON initial, run parameter is not getting pushed to
inside the vm. But its working when we power on VM using run once option
on Ovirt portal.
I believe we need to power ON vm using run once API, but we are not able
get this API.
Can some one help on this.
I got reply on this query last time but unfortunately mail got deleted.
Thanks & Regards
