[Xen-users] Getting Windows 2003 to run in multiple cores ???
Hi,
Installed Windows 2003 on XEN successfully (domain name : win1).
I could not get it running in multiple cores though (tried vcpus=4).
Windows taskmanager shows only 1 CPU always :-(.
Can someone help ?

Hi James, Thanks for the response. Unfortunately, "xm start" is not helping me either. Should I reboot dom0 to get this working ? I would like to keep it the last option to try as am facing other issues immediately after the dom0 reboot. Any other tricks to get multi-core working with Windows ? BTW, I could not find "xe" command in my XEN installation. Even after installing the "xe-cli" rpm file, it is failing Consistently with the error message : "Error: Connection refused (calling connect )" Thanks, -Madhu> -----Original Message----- > From: James Harper [mailto:james.harper@bendigoit.com.au] > Sent: Monday, August 03, 2009 4:40 PM > To: Madhu Venugopal (vmadhu); xen-users@lists.xensource.com > Subject: RE: [Xen-users] Getting Windows 2003 to run in multiple cores > ??? > > > Hi, > > > > Installed Windows 2003 on XEN successfully (domain name : win1). > > I could not get it running in multiple cores though (tried vcpus=4). > > Windows taskmanager shows only 1 CPU always :-(. > > > > This may not be your problem, but one thing that caught me out earlyon> is that if you make a change to the config file and then do a ''xm > reboot'' (or just do shutdown->restart in windows), the change isn''t > picked up - it runs with the old config.

Hi, Have you checked from your device manager that your windows is running the SMP HAL? It might not be autodetected upon adding the second CPU if Windows was initially installed with only one vcpu; If you''r system says ''ACPI Uniprocessor PC'' in the device manager (under Computer or something), try updating the driver (in which case the ACPI Multiprocessor PC would be found) or removing the device and then rebooting (and again, the smp hal should get autodetected). I''ve noticed that hardware changes do often require shutdown / xm start (or even xm create) to get applied, too. Another problem with W2k3 that I came by was running network in bridge mode (as opposed to NAT) in Xen 3.2-1; if vif was using ioemu, it would get added as tap0 (and tap1 and so forth) and apparently as vif[domid].0 etc too, of which the tap was the working iface but the scripts added only the non-working vif to brctl and the taps would have to be added manually after startup. This was addressed by using the GPL PV drivers, thankfully. ++antti Quoting "Madhu Venugopal (vmadhu)" <vmadhu@cisco.com>:> Hi James, > > Thanks for the response. > Unfortunately, "xm start" is not helping me either. > > Should I reboot dom0 to get this working ? > I would like to keep it the last option to try as am facing > other issues immediately after the dom0 reboot. > > Any other tricks to get multi-core working with Windows ? > > BTW, I could not find "xe" command in my XEN installation. > Even after installing the "xe-cli" rpm file, it is failing > Consistently with the error message : > > "Error: Connection refused (calling connect )" > > Thanks, > -Madhu > >> -----Original Message----- >> From: James Harper [mailto:james.harper@bendigoit.com.au] >> Sent: Monday, August 03, 2009 4:40 PM >> To: Madhu Venugopal (vmadhu); xen-users@lists.xensource.com >> Subject: RE: [Xen-users] Getting Windows 2003 to run in multiple cores >> ??? >> >> > Hi, >> > >> > Installed Windows 2003 on XEN successfully (domain name : win1). >> > I could not get it running in multiple cores though (tried vcpus=4). >> > Windows taskmanager shows only 1 CPU always :-(. >> > >> >> This may not be your problem, but one thing that caught me out early > on >> is that if you make a change to the config file and then do a ''xm >> reboot'' (or just do shutdown->restart in windows), the change isn''t >> picked up - it runs with the old config.

It''s not a version of windows that doesn''t allow SMP is it (I don''t know if one exists - I thought they all supported at least 2 CPU''s with up to 4 cores each). Are you running a diffent HAL?

Windows 2003 server. As you suggested it does support SMP. I checked the device manager.. & it says the computer as a "Standard PC". Looks like that is incorrect. How can I run a different HAL ?

My configuration file has explicit acpi=1 & apic=1. But during installation I remember following a step which suggested setting these values to 0. Maybe that is the root-cause of the issue that am seeing now. Will try to look for the info to switch to a different HAL. In the meantime it would be great if you can point me to any solid/proven documentation to do the same .

Tried messing with the dlls and ended up in blue screens... Hence reinstalled 2003 again & this time with acpi=1 & apic=1 during the installation and voila ... the multi-core is up and running.
