I am using a single Q9550 (quad core) cpu.
I installed winxp hvm guest and changed vcpu to 2 in the config file.
after winxp booted up with xm create, the processor is still 1.
pls advise how to assign 2 cpu to winxp.

I still have no luck after acpi=1 and apic=1. could you post your config? my xen version: virsh # version Compiled against library: libvir 0.6.3 Using library: libvir 0.6.3 Using API: Xen 3.0.1 Running hypervisor: Xen 3.1.0 --- 2010年1月27日 星期三，James Harper <james.harper@bendigoit.com.au> 寫道﹕ 寄件人: James Harper <james.harper@bendigoit.com.au> 主題: RE: [Xen-users] winxp and 2 cpu 收件人: "Aclhk Aclhk" <aclhkaclhk@ymail.com>, xen-users@lists.xensource.com 日期: 2010年1月27日,星期三,上午8:21> after rebooted 2 times, the processor was still single. > > pae = 1 > acpi = 0 > apic = 0Set acpi=1 and apic=1.

Virtualbox says virtualizing apic is "expensive", and I assume it''s the same thing on Xen, so I usually set it off whenever possible.> --- 2010年1月27日 星期三，James Harper <james.harper@bendigoit.com.au> 寫道﹕ > You may need a bit of trickery to get Windows to update the HAL but there are ways to do it.Looks like you haven''t done that part yet :P See: http://support.microsoft.com/kb/309283 (short story: you need halacpi) http://www.vernalex.com/guides/sysprep/hal.shtml (look for boot.ini. You only need the /HAL option, not /KERNEL. The necessary hal*.dll is available on Windows install CD). Note that choosing the wrong HAL might make your system unbootable, so it''s best to have BACKUP of domU''s disk image (even if it''s just LVM snapshot) and lots of test. It''s also handy to have kpartx and ntfs-3g, in case domU fails to boot and you need to access it''s filesystem from dom0. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
