There is none of enlightenment timer features enabled, I`d suggest to
start fixing the issue by adding them in the config. USB tablet is a
great problem too for a generated additional workload in idle, though
usb3 tablet connection results in much lower cpu consumption than
usb2.

Re: [libvirt-users] Processor usage of qemu process.

Spice seems to be doing the trick... Thanks a lot!

The tablet isn't removed or changed yet. I'll first do a follow up of
the spice before doing that...

How do I enable the enlightenment timer feature? I can't seem to find it in
the xml-doc's...

Assuming you've enabled the SPICE guest agent, then it should not use
the USB tablet, even if it is present.

The guest XML shown has not got either USB2 or USB3 controllers present,
so the tablet will be operating in USB1 mode which is awful for performance

Re: [libvirt-users] Processor usage of qemu process.

Results
----------

First I want to show my appreciation to Daniel and Andrey. So thanks...

I've implemented Spice, removed the touchpad and implemented enlightenment
timer...

PCVIRT1 with Windows 8.1 is on 5% host CPU usage... (OK)
CmsrvAPP2 with Server 2012 R2 is still on 50% (Bummer...)
A new freshly installed Server 2012 R2 with nothing activated or installed on
gives 12% (Not completely happy)

More tips are welcome....

See traceFlag T8038 section on https://pve.proxmox.com/wiki/Performance_Tweaks
I've also noticed it on other sources... On the CmsrvAPP2 the SQL server is
a SQL essential, so I have to figure out how to set the traceFlag on a SQL
essential...
