Hello group, I recently purchased an HP m7360n computer which has an Intel Pentium D 920 processor in it. Unfortunately there is no BIOS option to enable or disable VT. The board it sits on uses the Intel 945P chipset. If I am in linux and do a ''cat /proc/cpuinfo'' I get this: [root@localhost ia32]# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 6 model name : Intel(R) Pentium(R) D CPU 2.80GHz stepping : 2 cpu MHz : 2800.956 cache size : 2048 KB fdiv_bug : no hlt_bug : yes f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 6 wp : yes flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc pni monitor ds_cpl vmx cid cx16 xtpr lahf_lm bogomips : 7006.67 processor : 1 vendor_id : GenuineIntel cpu family : 15 model : 6 model name : Intel(R) Pentium(R) D CPU 2.80GHz stepping : 2 cpu MHz : 2800.956 cache size : 2048 KB fdiv_bug : no hlt_bug : yes f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 6 wp : yes flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc pni monitor ds_cpl vmx cid cx16 xtpr lahf_lm bogomips : 7006.67 Notice that it detects vmx, which is Intel''s VT.

Try "xm dmesg|grep VMX". If grep finds "(XEN) VMXON is done",it's VT enabled.

I do see that VT is enabled thanks to your suggestion. However, I cannot
boot an unmodified guest OS yet. Looking through the xen messages I see
this too:
(XEN) Domain 0 kernel supports features = { 0000001f }.
(XEN) Domain 0 kernel requires features = { 00000000 }.
Could this be a source of a problem? Or do you know where else I could look
to get an unmodified OS to boot? It hangs right when the hvmloader bios
starts to boot from a hard drive. I can though, boot from a Ubuntu or
Fedora install CD, however the computer hangs after the initial press of
[ENTER] to install the OS.
Thank you!

The two messages below are ok.
You can get a unmodified os by installing it into vmx.
The instructions about how to install a os into vmx could be found in xen
manual.
Thanks
Yunfeng

Notice that it detects vmx, which is Intel's VT.
My question is: Is there any way to tell if xen is using VT or to see if it is
even accessible? I really would like to get xen working in one way or another
and would much like to use VT with it.

I have followed the directions in the Xen documentation and now whenever I try to boot an unmodifed guest my computer hangs. Do you know anything that could be causing this?

I did get Windows XP to boot after a little more tinkering and updating xen to 3.0.2. However, i cannot specify a file backed file system. I get this error: Error: Device 768 (vbd) could not be connected. Backend device not found. If I could get past this error I belive me xen setup would be complete.

The "Device 768 (vbd)" error is a known issue of xen. You can solve this error with executing the command "losetup -d loopX".
