Xen virtualization in centos
Dear Experts:
I have centos 5.5 recently thought to deploy the virtualization hence installed the virtualization packages by yum groupinstall "virtualization" and also modified the grub.conf to load the xen kernel, the server hardware cmos Hyperthreading is enabled still when grep is done for vmx as my server is Intel based nothing output.
i tried, grep -i "vmx" /proc/cpuinfo. for this iam not getting any output please suggest me should i do any changes or only the paravirtualizaton is possible.

Thanks for the help. Sir if the hyperthreading is enabled in the cmos that means the hardware supports the full virtualization now by doing the BIOS update this will be resolved . please suugest in this.
Yeah if you Virtualization is not available after you check the appropriate setting you'll definitely need a BIOS update.

BTW are you sure the processor you use actually support vmx feature? what is the CPU in question? If you are sure it actually supports vmx extension then it must be a BIOS issue.
Will you post the contents of your /proc/cpuinfo here ?

Thanks for the reply , attached the /proc/cpuinfo for your reference please let me know if doing bios update will this cpu support the full-virtualization.

If vmx does not show in your cpu flags nothing you can do with software settings would enable this. This is a hardware feature and must be enabled before you can use it. This has occurred to me before. Some motherboard BIOSes don't enable virtualization even if you enable it through BIOS settings. These systems require a BIOS update for proper operation. Please contact your vendor and ask for such a BISO update.
