JackXie, could you please provide me the model number of your motherboard or the system you are using? I would like to replicate this issue, but I need all the information you could provide me.
A detail description of the behavior will be helpful.
motherboard : Intel H65
HOST OS - Win7 64bit Ultimate
CPU - Intel Core(TM) i5-3470 CPU @ 3.20GHz
RAM - 8GB
TOOL - VMware workstation10
Guest OS - Ubuntu10.04 desktop 64bit,
Now I want to run another virtual machine with kvm on Ubuntu10.04, So I need to modprobe kvm-intel on Ubuntu10.04,
but as I said, "Operation not supported" occured, dmesg shows "Hardware not support".
I already enabled Intel Vituallization Tech In BIOS Advanced Settings.
Thanks for the information Jackie. I'm going to set up a lab in order to try to replicate this behavior.
I'll keep you posted
JackXie, I would like to inform you that we are still working on this issue.
Once we have an update I will let you know.
