Hi, I have a Dell opt 755 machine and installed Xen 3.3.1. The CPU is core 2 due E6550, which as the vmx flag. However, when I reboot the machine to xen 3.3.1. I can not find vmx in the /proc/cpuinfo. But vms appears in the kernel 2.6.29 (not xen kernel). Can anyone help on how to enable vt in this machine? Thanks.

It must be enabled in the bios.

I think I have enabled it in BIOS. I pressed F2 during the boot and set the virtualization on. I noticed this error message in "xm desg" (XEN) Detected 2327.544 MHz processor. (XEN) CPU0: VMXON failed: perhaps because of TXT settings in your BIOS configuration? (XEN) --> Disable TXT in your BIOS unless using a secure bootloader. (XEN) VMX: failed to initialise. Any suggestion? Thanks.

It gives me # xm dmesg | grep -i vmx (XEN) CPU0: VMXON failed: perhaps because of TXT settings in your BIOS configuration? (XEN) VMX: failed to initialise. I have set virtualization on during boot time. But it seems fail. Any suggestion?

Hi, did you set iommu=1 in your grub-line? This should fix this problem.

Hi, Thomas, Thanks for your comment. But it gives the same error message.>> (XEN) CPU0: VMXON failed: perhaps because of TXT settings in your BIOS >> configuration? >> (XEN) VMX: failed to initialise.Do you think this maybe the motherboard issue?

You have to disable TXT in the BIOS if you''re not using it...

After google some time, I don''t what does the TXT setting mean in BIOS? Also the xm dmesg still gives me (XEN) CPU0: VMXON failed: perhaps because of TXT settings in your BIOS>>>> configuration? >>>> (XEN) VMX: failed to initialise.Can anyone help? 2009/5/26 Christian Tramnitz <chris.ace@gmx.net>:> Steven wrote: >> >> Hi, Thomas, >> Thanks for your comment.

The problem solved. TXT means trusted execution technology. It can be disabled in your BIOS setting. Thanks to all. - Steven On Tue, May 26, 2009 at 1:52 PM, Steven <wangwangkang@gmail.com> wrote:> After google some time, I don''t what does the TXT setting mean in BIOS? > Also the xm dmesg still gives me > (XEN) CPU0: VMXON failed: perhaps because of TXT settings in your BIOS >>>>> configuration? >>>>> (XEN) VMX: failed to initialise. > Can anyone help? > > > 2009/5/26 Christian Tramnitz <chris.ace@gmx.net>: >> Steven wrote: >>> >>> Hi, Thomas, >>> Thanks for your comment.
