Backup Ovirt VMs with Python not working
by daniel94.oeller＠gmail.com
Hello,
I have set up Ovirt Backup how it is explained in this link:
http://blog.infratic.com/create-ovirtrhevs-vm-backup/
I also have changed the settings on the default.conf.
When I started the backup it works until it begins to create the qcow2 file
It writes:
qemu-img: Could not open '/home/DC01/2019-03-20-20/DC01_Disk1.qcow2': Failed to get shared "write" lock
Is another process using the image?
Have anyone ideas and can help me?
Thanks

Re: Save Virtual Machine in NFS partition
by Strahil
Hi ,
Without the engine - this will be hard.The engine knows the configuration and the disks of each VM so the Hypervisor can start it.
In your case I would focus on the engine as this could be (or not) the easier approach.
Otherwise you need to run qemu-img against each image (just an uuid, no meta or lease ) , find your image and copy it to a standalone KVM.
Once you have the disk, you should try to recall what was the host CPU type (should be the same on the whole cluster) and create a new VM using a COPY of your image .
If KVM manages to start and the machine boots - you are done.
As you can see , fixing the engine might be easier - especially with the help of the community.
Best Regards,

Save Virtual Machine in NFS partition
by siovelrm＠gmail.com
Hi, I had problems with my ovirt-engine and it does not raise. I have some virtual machines in an NFS domain that is located in one of the nodes and I want to get one of the virtual machines. The problem is that what appears is a series of identifiers (ID) and I don't know what the virtual machine is, because by name I can not find it.

4.2.7 Importing qcow2 linux as disk
by Arnaud DEBEC
Hi,
I want to import a Centos 7 qcow2 VM on oVirt 4.2.7.
0. the Centos 7 VM was previously running under libvirt / kvm hypervisor.
1. on Ovirt 4.2.7, I imported the VM qcow2 via Storage > Disks > Upload > Start > etc.
2. I created a VM and attached the disk and specifying the disk is bootable
3. When the machine boots, I get "Warning: /dev/disk/by-uuid/XXXXXXXXXX does not exist"
Before going in deeper detail in the investigation, I would like to make sure if the previous steps make sens for importing a VM under qcow2 format. Most of documentation I found to import libvirt /KVM are done by using the Compute > VM > import > KVM (via Libvirt) which is not what I am looking for.
Thank you.

Fwd: Re: Change cluster cpu type with hosted engine
by Fabrice SOLER
Hi,
As you can read on the screenshot below, my servers have got Nehalem CPU
type, so the hosted engine detect the correct CPU type.
You can read on this link
https://www.intel.com/content/www/us/en/support/articles/000006105/proces...
that Windows 10 x64 does not support Nehalem CPU type. Bill is cutting
the fonctionnality for the old CPU, I will be able to comment but i will
not.
But I need to use Windows 10 x64 with this servers for my students !!!
I am in a dead-end.
Sincerely,
Fabrice SOLER

Hello,
The first host is a DELL R610 (an old server). At the installation, the
cluster was created with an CPU Architecture x86_64 and CPU type Intel
Nehalem Family.

Can't you make the script check if it windows or Linux and skip if it's Linux?

The problem seems to be that I cannot use it in the VM because from what I have been finding out is that it gets and error code 43. Nvidia drivers disable the card if it detects that its being used in a VM. I have found some code to use to hook it into the xml before_vm_starts.

Daily reboots of Hosted Engine?
by Juhani Rautiainen
Hi!
Hosted engine reboots itself almost daily. Is this by design? If not,
where should I be searching for the clues why it shuts down? Someone
is giving reboot order to HE because /var/log/messages in contains
this:
Mar 19 12:05:00 ovirtmgr qemu-ga: info: guest-shutdown called, mode: powerdown
Mar 19 12:05:00 ovirtmgr systemd: Started Delayed Shutdown Service.
And I'm still running v4.3.0 because upgrade to that was bit painful
and haven't dared to new round.
Thanks,
-Juhani

vender_id syntax UserDefinedVMProperties
by Darin Schmidt
Hello all, im trying to figure out how to configure the custom properties
to enable my NVIDIA card to work in the VM. Its my understanding that the
drives dont work because it detects its in a VM......
Im trying to do something like this:
engine-config -s
UserDefinedVMProperties="kvmhidden=^(true|false)$;{type=vendor_id;state={^(on|off)$;value=^([0-9])$}}"
But thats clearly not working. If I do this:
engine-config -s
UserDefinedVMProperties="kvmhidden=^(true|false)$;vendor_id={state=^(on|off)$;value=^([0-9])$}"
It works but, the options are messed up. Im not sure how to find out the
correct syntax to get this to work. Would appreciate any advice.
