Comment 7 Jinxin Zheng 2011-12-07 07:45:22 UTC
Verified on an Intel Q9400 CPU.

In kernel-xen -298, `xm dmesg` shows these:

(XEN) VMX: Supported advanced features:
(XEN)  - APIC MMIO access virtualisation
(XEN)  - APIC TPR shadow
(XEN)  - Virtual NMI
(XEN)  - MSR direct-access bitmap

while in kernel-xen -274, there's no such message.
