Re: [Xen-users] how to enable VT

[Steven <wangwangkang@xxxxxxxxx>]

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? Thanks.
