dc3 1 3 3 --- 12.9 3 The problem goes away if I tell Xen to boot with options dom0_max_vcpus=1 dom0_vcpus_pin. What's the difference between Xen boot options to limit vcpus for dom0 to /etc/xen/xend-config.sxp? I am running Xen 3.4.1-rc6 version. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
