[ovirt-users] Re: VLANs with one NIC in ovirt

2019-12-05 Thread Joseph Goldman 

Yes, under networks you can create new and specify VLAN tags.

When you add NIC's under the VM, you choose the new Network you chose 
and the interface on the VM will be automatically then on that VLAN.

Hey,



The problem what I have found is when I am using SPICE as default console
option, the  console performance is very sluggish. So what I understand
here is one needs to install additional spice guest tools to improve the
performance as it includes QLX video driver.


Yes. So did you do that?

The moment I switched to VNC console options, performance improved but not
far better as it should be when taking a console of machine.



So still any suggestions to improve console access?

What is your virtual GPU ?
I'm using QLX, and despite being sluggish, when you tune windows for best
performance -it is workable.

Of course, if you passthrough a GPU, performance will be completely
different.

Hello Everyone,



I managed to install Windows Server 2016 server on Ovirt node using ovirt

Can anyone let me know, what could be the reason. Not able to to even add

No, proxy host is the host you select to use for import. One of your

[ovirt-users] Importing a Virtual Machine from a KVM Host

2019-12-05 Thread Dirk Streubel 
Hello everbody,

i am just a little bit confused about importing Qemu Images from my KVM Host.

At home, and at work i am using a ovirt engine in a VM. The Version is 4.3.7 
and on bare metal my host.

Everything works fine but i have the same problem at home and on work. I want 
to import my qcow2
Images from a KVM Host but i

will not work.

The command  virsh -r -c 'qemu+tcp://r...@host1.example.org/system' list --all 
shows me akk my VMs.

But when i want to load the images in the GUI, nothing happens. I follow this 
instruction:

https://www.ovirt.org/develop/release-management/features/virt/KvmToOvirt.html

After that, i take a look on the official 4.3 Rhev Documentation from Red Hat. 
There stand this:

Log in to the proxy host and generate SSH keys for the vdsm user.

sudo -u vdsm ssh-keygen

So, i have no proxy host.  So i want to do this on my ovirt-engine. Is this 
right?

Next thing: the user vdsm is locked on the ovirt-engine machine and the host.

So, do i have to unlocked the account of the user vdsm or what is the best way.

My Problem is i found nothing that would help me to solve this problem.

Maybe somebody here do me a favour and help me to solve this "challenge"

Regards

Dirk

Yes, I'm saying ovirt defaults to using 15 sockets * 2 cores if you don't
specify a different "advanced" configuration. This also leads to a funny
behavior that you can't increase the VMs from 30 to 35 cores online.
