Re: Processor usage of qemu process.

I found a fix for the Windows 8.1 guest by changing the xml like:

<model type='vmvga' vram='1048576' heads='1'/>

Instead of 

<model type='vga' vram='1048576' heads='1'/>

If someone knows a fix for the Windows Server 2015 R2 guest, I would appreciate it...

I have been using libvirt for a while now with some linux guest installed. And everything has been working great.

I've got a nice new (used) HP virtual host with 12 x dual core and 48Gb mem. My Windows servers are getting old, so I found it was time to take the next step and also virtualise my Windows systems.

Now I've got two Windows guests on my new host:
- A Windows 8.1 which runs a Autodesk Job Processor
- A Windows Server 2012 R2 which runs a Pervasive SQL, Autodesk Vault Server (MSSQL, IIS), Autodesk license server,...

The first is constanly using 30% host-CPU and the second one is using 50% host-CPU. Both guests are using <5% guest CPU...

(Host system load is between 0.1 and 0.3...)

Is it normal Windows guests take up 30% to 50% host CPU resources? The Windows 8.1 is actualy a simpel PC with almost no activity...
