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 ?
