Hi Everyone, I install XCP on a 12 core server, and with Hyper threading the core should show 24 core, When I use “top”, it only show 4 cpu, and I use cat /proc/cpuinfo it’s the same, But when I user “xentop”, the Dom0 have 24 vcpu, My question is ,how can I make sure the XCP use all CPU? Can anybody give me some hint ? klein _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
