[Xen-API] Xen 3.4.2 can not recognize Intel-vmx

[çèå Luwei Cheng <chengluwei@xxxxxxxxx>]

Dear All,

I am testing the HVM performance of Xen 3.4.2 with centos-5.4 on Dell PowerEdge R610 with Intel Xeon E5540 processors. However, it seems that Xen 3.4.2 can not recognize VMX at all. Anyone who are familiar with the problem? Thank you very  much.

Best Regards,

CHENG Luwei

The following information of CPU flags are for your continence to diagnose the problem:

$ cat /proc/cpuinfo
