hi,
we just noticed that while we run a guest with 4vcpu (the host has 4 core):
-----------------------------------------
3278 ? Sl 2138:49 /usr/bin/qemu-kvm -M pc -m 2048 -smp 4
-monitor pty -boot c -hda /dev/VolGroup00/centos-i386-root -hdb
/dev/VolGroup00/centos-i386-swap -hdc /dev/md2 -net
nic,macaddr=00:16:3e:58:66:7b,vlan=0 -net
tap,fd=11,script=,vlan=0,ifname=vnet0 -usb -usbdevice tablet -vnc
127.0.0.1:0
-----------------------------------------
