4.2.7 Importing qcow2 linux as disk
by Arnaud DEBEC 20 Mar '19

20 Mar '19

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 20 Mar '19

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/processo… 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.

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

Daily reboots of Hosted Engine?
by Juhani Rautiainen 20 Mar '19

20 Mar '19

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 19 Mar '19

19 Mar '19

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.

Hi, I tried to create windows2012 vm on nfs data domain, but the disk was locked. Found the error message as following: Connection to ovirt-imageio-proxy service has failed. Make sure the service is installed, configured, and ovirt-engine certificate is registered as a valid CA in the browser. Is this known issue? Thanks, Jingjie

Change cluster cpu type with hosted engine
by Fabrice SOLER 19 Mar '19

19 Mar '19

Hello, I need to create a windows 10 virtual machine but I have an error : I have a fresh ovirt installation (version 4.2.8) with an hosted engine. At the hosted engine installation there was no question about the cluster cpu type, it should be great if in the future version it could be. To change an host to another cluster this host need to be in maintenance mode, and the hosted engine will be power off. I have created another Cluster with an SandyBridge Family CPU type, but to move the hosted engine to this new cluster the hosted should be power off. Is there someone who can help ? Sincerely, --

Yeah, That's because my phone corrects the 'gluster' to 'cluster' Usually gluster daemons detect need of heal, but with 'gluster volume heal data full && sleep 5 && gluster volume heal data info summary && sleep 5 && gluster volume heal data info summary', you can force syncing and get the result. Let's see what happens with DNS. Best Regards, Strahil Nikolov
