I revisited this and found that a Windows Server 2003 R2 HVM is fine with ACPI and APIC. Perhaps it is Windows XP that triggers the problem. 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 XP Pro SP2 HVM using ACPI HAL or APIC HAL. > On Tue, Dec 09, 2008 at 03:44:12PM -0700, Nick Couchman wrote: >> Here's my working configuration: >> 1) Intel Xeon E5335 >> 2) SLES 10 SP2 64-bit (2.6.16.60) >> 3) Xen 3.2.0 (build included with SLES10 SP2) >> 4) 32-bit Windows HVM using APIC HALs >> >> I have ~15 Windows HVM domUs running with absolutely no performance >> issues, plus several PV domUs. >> > > Hello. > > Might be a good idea to post your configuration file for those (working) > windows hvm domains.. just so that people can verify all the settings. > > -- Pasi > > >> -Nick >> >> >> >> >> -----Original Message----- >> From: Oliver Wilcock <oliver@xxxxxxx> >> To: Xen-users@xxxxxxxxxxxxxxxxxxx >> Subject: RE: [Xen-users] HVM Cpu performance 3.2 >> Date: Tue, 9 Dec 2008 14:50:37 -0500 (EST) >> >> >> So far we have: >> 1.
