Hello all, I have Xen 3.0.3 64 bit SMP(installed from binary tarballs) running on Debian stable/testing, and I''m trying to run Windows 2003 server (32 bit) as a domU. I have created .hvm configuration file, disk images and all, but when I’m creatin a vm using the following command, xen doesn’t recognise VT support in CPU: # xm create /etc/xen/vm01-w2k3.hvm Using config file "vm01-w2k3.hvm". Error: HVM guest support is unavailable: is VT/AMD-v supported by your CPU and enabled in your BIOS? The problem is that the hardware does support HVM; the CPU is Pentium D 945 and the motherboard is ASUS P5LD2-VM. I checked bios settings, and they should not give me any trouble(legacy os support is disabled). I suspect that xen still doesnt recognize vt correctly on x86_64 systems. Configuration and /proc/cpuinfo files are attached, may be they shed som light on the problem. (cpu info file obtained from under em64t-p4-smp kernel) Any help appreciated.

I believe VT is only available on dual-core Xeon CPUs. ----- Original Message ----- From: "Alex Volkov" <Alex.Volkov@netcraftcommunications.com> To: <xen-users@lists.xensource.com> Sent: Thursday, October 26, 2006 1:02 PM Subject: [Xen-users] Xen-3.0.3 does not recognise VT Hello all, I have Xen 3.0.3 64 bit SMP(installed from binary tarballs) running on Debian stable/testing, and I''m trying to run Windows 2003 server (32 bit) as a domU.

Chipset on the motherboard is intel 945G, which does support VT http://wiki.xensource.com/xenwiki/IntelVT The only bios option that hinted on disabling VT is Advanced -> CPU Configuration -> Max CPUID Value limit [Disabled] I did not find any other options that explicitly enable/disable VT.

On all 3 VT systems I''ve seen, there is an explicit entry in the BIOS that says "virtualization extensions [enable/disable]" If there''s nothing like that in your BIOS, I''d assume that even though the chipset might support VT, the BIOS does not. You could see if ASUS has a newer BIOS out for your board. If they don''t, I''d poke around the forums on the ASUS global site. Unfortunately, I''ve recently had bad luck with ASUS BIOS support. - Steve Stephen Brueckner, ATC-NY _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
You need VT version of BIOS which can enable VT support in your BIOS. ----- Original Message ----- From: "Steve Brueckner" <steve@atc-nycorp.com> To: <xen-users@lists.xensource.com> Sent: Thursday, October 26, 2006 2:29 PM Subject: RE: [Xen-users] Xen-3.0.3 does not recognise VT> Alex Volkov wrote: >> Chipset on the motherboard is intel 945G, which does support VT >> http://wiki.xensource.com/xenwiki/IntelVT >> >> The only bios option that hinted on disabling VT is >> >> Advanced -> CPU Configuration -> Max CPUID Value limit [Disabled] > > That''s not it.
