Hello everybody,
I just discovered in my CPU

Linux pcfarm-new.pnpi.spb.ru 2.6.18-194.3.1.el5xen #1 SMP Fri May 7 02:05:32

that there is no flag 'vmx'
[r...@pcfarm-new ~]# grep vmx /proc/cpuinfo; echo $?

At the same time when I boot another kernel 'xen.gz-2.6.18-128.1.1.el5'
the flag 'vmx' is in place
Hmm. The flags are indeed different with xen and non-xen kernels.
I guess this is because with a xen kernel you are looking at the
capabiities of the *virtual* CPU, rather than the bare metal processor ?
