Hello,

I've finally got xen to boot and a domain0 kernel to come up (after much manual building with drivers compiled into the kernel; and figuring out the noreboot option for the xen kernel so you can read the console..).

 However I cannot create an hvm guest.  xm create <config file> reports

xm create xpcdxm.hvm
Using config file "xpcdxm.hvm".
Error: Not an HVM capable platform, we stop creating!


The vmx status does not show up in cpuinfo  and the xm dmesg does not report that it is enabled or disabled.  How can it be enabled or at least probed.... the cpus are on the list of Xeons that support VT.  Any help would be appreciated.   cpuinfo and xm dmesg follow below

Thanks,
Doug
