Is there a problem specifying multiple cpus with Windows 2000? I''m running a dual quad core system and RHEL5, and my paravirtualized RHEL5 systems seem to be able to accept more than one cpu, but the Win2K fully virtualized system just shows 1 - no matter how many vcpus I specify. Config file looks like so: name = "plcdata" builder = "hvm" memory = "2048" disk = [ ''file:/dg/xen-plcdata,hda,w'', ''file:/usr/src/pc.iso,hdb:cdrom,r'', ] vif = [ ''type=ioemu, bridge=xenbr0'', ''type=ioemu, bridge=xenbr1'', ] device_model = "/usr/lib64/xen/bin/qemu-dm" kernel = "/usr/lib/xen/boot/hvmloader" vnc=1 vncunused=1 apic=1 acpi=1 pae=1 vcpus=2 serial = "pty" # enable serial console on_reboot = ''restart'' on_crash = ''restart'' Any suggestions appreciated. Thanks much... -- Tim Boyer Director Information Systems and Engineering Projects Denman Tire Corporation tim@denmantire.com _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

At the time, I was testing only Windows HVM guests. The GNU/Linux guests during my tests tended to be paravirtualized.> >> Additionally, was the >> guest installed with these same settings?

Could that > have made the difference?I''m pretty sure the Standard PC HAL only supports 1 CPU, so this is probably the problem. Have you tried selecting one of the alternatives? Sadly this requires a reinstall of Windows (you may be able to force the change by copying the right files to the right places, but I''ve no idea what they are). I can''t remember which version of Xen I was trying at the time, but I remember seeing 2 multiprocessor choices. One was an ACPI one, the other was MPS multiprocessor. I couldn''t get reliable results with the ACPI Multiprocessor PC, but I had some success with MPS. However, on Xen 3.1 I can use ACPI Multiprocessor without problems. I''d suggest trying MPS Multiprocessor PC, or upgrading to Xen 3.1. Mart> > -- tim -- > >> Mart >> >> Tim Boyer wrote: >>> Is there a problem specifying multiple cpus with Windows >> 2000?
