I''ve been trying to get Xen working on a quad socket Barcelona system but I it hangs just after the Xen hypervisor prints "Brought up 16 CPUs" - The system will run standard Redhat Linux - Xen will run if I only power up 2 of the 4 sockets (8 of the 16 cores.) I''m still using Xen 3.0.4 but did try Xen 3.1.0 with out any luck. If anyone can answer the following I''d be greatfull. Has anyone been able to successfully bring up Xen on a quad socket AMD Barcelona system? What version of Xen were you running? What rev of Barcelona were you running? Thanks. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Did you built the Xen kernel with VSMP option enabled instead of default PC86 ? I think 2.6.18 does not support this option. Sure this option is avaliable on 2.6.26 kernel config.
