[ovirt-users] Re: Windows Sluggish Performance

[Gal Zaidman]

Hi Vijay,

You need to install Spice driver + agent,
Driver qxl-wddm-dod:
https://www.spice-space.org/download/windows/qxl-wddm-dod/qxl-wddm-dod-0.19/
(Notice it is not the qxl)
and the agent:
https://www.spice-space.org/download/windows/vdagent/vdagent-win-0.9.0/

We have an installer for virtio-win drivers:
https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-virtio/virtio-win-0.1.173-2/
that should install both of them

[ovirt-users] Re: Issue deploying self hosted engine on new install

[Nate Revo]

Is it potentially an SELinux denial?  I seem to recall an SELinux Boolean
that needs to be set on the nfs server.

[ovirt-users] Re: Issue deploying self hosted engine on new install

[Robert Webb]

Didi,

Apologies for the delayed reply.

I tracked the issue down after giving up on the self hosted install. I 
installed it to a VM running CentOS 7 running on another platform and then 
added my hosts. 

After adding the hosts and dploying a VM on oVirt, everything deployed 
perfectly, I could never get the VM to start. Digging further, I found that it 
is apparently a NFS permission on my NAS. What is odd is that I can add the 
Storage domain with no issues, I can create a VM, but the VM will never start 
due to a permission issue on the disk image.

On my NAS if I just go into the shared folder permissions and not change 
anything but just tell it to apply configured permissions to all files and 
folders, the newly created VM runs just fine. For some reason when oVirt 
creates new files in storage, it is leaving off the execute for the vdsm user. 
I also notice that for the image and lease files, it also leaves off any 
permisson for "other" . NOt sure why the permissions are not being applied 
correctly. But that is an issue for me to figure out on my NAS, OpenMediaVault.

When you edit the memory, wait till tomorrow before  powering off and powering

The file in 3.1  is just a backup :D

[ovirt-users] Re: Hyper-V to KVM | v2v

[Mathieu Simon]

Yes, that is pretty much expected.

Maybe I wasn't clear: You first need to check whether your Hyper-V VM
in question is a Gen 2 UEFI-based VM or a legacy BIOS-based
Gen 1 VM. (It's quite likely Gen 2 since this has been the default
since Hyper-V on Server 2012 R2)
This defines the way on how the destination VM on the oVirt side needs
to be configured.

Once that is identified, try the according machine type on the oVirt
side there that converted disk is attached to:
- Hyper-V Gen 1 => oVirt 440FX + SeaBIOS (default in oVirt as of writing)
- Hyper-V Gen 2 => oVirt Q35 + OVMF

As written previously: There are still plenty of limitations in the
UEFI guest support and they sometimes
need workarounds until hopefully oVirt 4.4 closes most of these gaps.

Regards
Mathieu

thank you for your replay,

I am happy if it works
1. check
2. check
3.1 check -> I cant see where is use this config file later, or it is just a

4.1 check i changed to
  16384
  16384
and

  15625000
  15625000
  15625000

after write, quite und open these values have changed back to
  4194304
  4194304

BREAK ;) 

after stopping the hosted engine with hosted-engine --vm-shutdown and powering 
it up with hosted-engine vm-start
everything is reverted ;(

BREAK

hosted engine is now up and running, maintenance ist still global,
changed again with virtsh edit HostedEngine. as written above it changes back

I will wait for tomorrow.

Or did I missunderstand something

In which file the maxmem is hidden?

[ovirt-users] Re: Increase memory of hosted engine

[Strahil Nikolov]

 I know a way, but I'm not sure if you will be happy with that approach.1. 
Setup virsh on all hosts:alias virsh='virsh -c 
qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf'
2. Set the HostedEngine in maintenancehosted-engine --set-maintenance 
--mode=global3. Get the HostedEngine's current config3.1. When Engine is 
running - go to the host and type:virsh dumpxml HostedEngine > 
HostedEngine-2019-12-08.xml
3.2. If the engine is dead - take the xml from the vdsm.log (when it was last 
started)4. Edit the configuration4.1. If the engine is running -> edit directly 
with virsh edit HostedEngine4.2. If the engine is not running -> edit the xml 
with the new values and define the ovirtmgmt network and the 
VMvdsm-ovirtmgmt.xml :  vdsm-ovirtmgmt  
8ded486e-e681-4754-af4b-5737c2b05405    

virsh net-define vdsm-ovirtmgmt.xmlvirsh define HostedEngine.xml
4.3 You may try to power up the VM but it will complain about some links from 
the gluster's storage to local one. Just create those symbolic links and power 
up the VM againvirsh start HostedEngine
5. Keep the engine running for at least 6 hours (to update the OVMF),as even 
when the OVMF update inteval is reduces -> the engine still ignores that.
6. Power off the engine gracefullyssh engine "poweroff"7. Power on the engine 
viahosted-engine --vm-start8.Once the engine is up , ssh and verify memory 
9. Remove maintenancehosted-engine --set-maintenance --mode=none
I haven't tested this approach of extending memory , but it should work.

I can increase the memory up to 7936 MB in the manager, it changes immediately.
I can not increase to more then 7936 MB because this is max Memory

If I change Max memory to 16384
the gueanted memery gets a red border an the error is max memory ist 4096 MB

I ve found this one https://access.redhat.com/solutions/964693

I ve also stoppt every ovirt-ha-agent and changed every vm.conf.
After starting ovirt-ha-agent every vm.conf changed to 4096 again

has somebody a solution to increase the memory again?

Hi,

So I wiped everything and went through the wizard to set up hyper converged

Storage was created OK and it went straight on to hosted engine deployment
this failed with the same error…

I have this in vdsm.log

Do you have any idea ?

[ovirt-users] Gluster FS & hosted engine fails to set up

[rob . downer]

I have set up 3 new servers and as you can see Gluster is working well, however 
the hosted engine deployment fails 

can anyone suggest a reason ?

I have wiped and set up all three servers again and set up Gluster first.
This is the gluster congig I have used for the setup.

Please review the configuration. Once you click the 'Finish Deployment' button, 
the management VM will be transferred to the configured storage and the 
configuration of your hosted engine cluster will be finalized. You will be able 
to use your hosted engine once this step finishes.

[ovirt-users] How to run oVirt on CentOS 8 (or 8.1 or Stream)

[Nate Revo]

I have a system that requires the 4x kernel to run and wanted to run oVirt
on top of CentOS.   Seems as I'm looking around, rhel/centos 8 support for
ovirt is slated for v 4.4. What's the progress with running on Centos 8+
and how do I run ovirt on Centos 8, now.

Thanks in advance,
-Nate Revo

P.S.  Will code for pizza
