Hello, I have a system with Intel core-duo. Linux sees 4 cpus (2 core duo +HT). I installed Xen on the same box and it reports only 1 proc in /proc/cpuinfo. It is an SMP kernel and also I have not placed any restriction on dom0 cpus. ie. there is no maxcpus flag in /etc/grub.conf and in xend-config I have (dom0-cpus 0) which should give dom0 all available cpus. There seems to have been an issue earlier, but i see no resolution posted http://lists.xensource.com/archives/html/xen-users/2007-01/msg00801.html TIA - Prabha _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Xen itself has probably detected the two cores and hyperthreads fine, and they will be used by guest VMs. Best regards, Jacob>_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

You can change that default, or boot the -xen kernel as dom0, to get an SMP dom0. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
