[Xen-users] Problems running Windows XP with Multiprocessor Support
Hi, First of, thanks for creating a great product that is xen. I am using Fedora 8 (x86) with kernel-xen-2.6.21.7-5.fc8, xen-libs-3.1.2-5.fc8 and i am using virt-manager to manage my guest domains. Recently i created a new windows vista guest with 2 processor allocation, and everything seems to work just right. later, I installed Windows XP with service pack 3, with 2 processor allocation, everything seems to work fine, but then the virt-manager reports of very high cpu utilisation. Even when the guest is idle the reported cpu utilisation is around 24-30%. Also the system refuses to poweroff on shutdown and displays the "It is now safe to turn off your computer" message. And again when this message is displayed the CPU utilisation (as reported by virt-manager) is 24-30% . if i install windows xp with service pack 3 and single processor allocation, i do not see these issues. the reported cpu utilisation os low, system power''s off at shutdown, etc. do you guys see similar behaviour? Is there something that i need to do to get this fixed? Secondly my processor has some Virtualization technology. So i would like to know whether i should use paravirtualization or full virtualization for my linux guests. Please Comment Regards ~Sameer _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Make sure that your domU configuration has ACPI=1 and APIC=1. If this is not the case, you''ll need to change that configuration and then install a new Windows HAL that supports APIC and ACPI. -Nick>>> "Sameer Naik" <sameer.subscriptions@damagehead.com> 2008/11/23 05:32 >>>Hi, First of, thanks for creating a great product that is xen.
