Windows 2000 KVM VM, more or less idle, but a processor on the proxmox host is always maxed out around 100%
1 CPU, 1 core assigned, ACPI enabled in Proxmox, ACPI multiprocessor HAL
CPU was set to host, changing it to Pentium 3 had no effect.
Have modified registry as per Microsoft KB
http://support.microsoft.com/default.aspx?scid=kb;EN-US;919521
No effect.
Have read these threads:
http://forum.proxmox.com/threads/3667-High-CPU-load-for-windows-2000-server
High CPU load for windows 2000 server
and

kvm high cpu load running a Windows 2000 VM
Config:
Questions:
1. I don't see any acpi: 1 line in the config with ACPI support disabled in the web GUI.
When disabling ACPI in the web GUI, I do see acpi: 0
I suppose that is how it is supposed to be?
(Manually setting acpi: 1 in the config file doesn't seem to have any effect on CPU usage)
2. I suppose I could try and disable ACPI, and change the HAL in Windows from ACPI multiprocessor to something else (MPS uniprocessor?); would that have any effect?
Any tips on getting the CPU usage down?
Thanks!
