(disabled)Fully Virtualization radio button in XEN
 
i installed Xen packages in a RHEL 5 server x86_64. Currently i could successfully run virt-manager, but when i start to make a vitualized OS i was only left with the choice "paravitualized" the radio button "fully virtualized" is disabled. I want to choose the "fully virtualized". What seem to be the problem? hope you could help me in this one.

thanks:)..

most likely it is because the host CPU(s) do not support VT extension or the VT is not enabled in the host BIOS.

What is your hardware? Esp. which CPU do you have?

You can check both Intel & AMD CPU's w/:
Code:

egrep -e 'vmx|svm' /proc/cpuinfo
If the command returns nothing, then the CPU does not have hardware-assisted virtualization support. AMD-V ("Pacifica") chips will show "svm" in the flags line of /proc/cpuinfo, while Intel VT ("Vanderpool") ones show "vmx".

For more info see http://en.wikipedia.org/wiki/X86_virtualization, particularly

I have the problem with xen.
Previously I have installed xen and was working fine, now I have reinstall the whole system again and at this time the xen kernel is rebooting again and again.

What could be the caused?

sorry for replying in this mail as I am not getting any response from the members.

Thanks-
