RE: [Xen-users] HVM Cpu performance 3.2

["Oliver Wilcock" <oliver@xxxxxxx>]

So far we have:
1. AMD CPU
2. kernel 2.6.16?  32 or 64 bit
3. Xen 3.2
4. guest is 32 bit Windows HVM using ACPI HAL or APIC HAL.

Result: unusable performance for Windows HVM.

Anyone out there using the above combination without problems?
