KVM "ERROR Host does not support any virtualization options"
 

I have a KVM (CentOS 6.5)on x86_64 sandbox that was working (created a CentOS client, tested, deleted it).

Now when I run virt-install, I get the following error:
ERROR Host does not support any virtualization options

I didn't change anything (yes, I know you've heard that one before!)

Any help will be appreciated, thanks in advance.

Here is all the info I can think of to post:

virt-install command:
virt-install --os-variant=rhel6 --network bridge=br0 --disk /dev/dm-2 --cdrom=/dev/sr0 --ram=2048 --vcpus=1 --name sirius

virt-install comand output:
ERROR Host does not support any virtualization options

Your CPU has the vmx flag but that does not mean that virtualization is turned on in the BIOS. Try:

Did you run virt-install before?

I'll have to agree that maybe bios could have been changed by some fluke if it worked before.

Very unlikely that motherboard or cpu support has become damaged somehow.

Thanks for your input, I ran modprobe kvm_intel and tailed (last ten lines) of dmesg:

I also ran yum update (updated 144 packages), but that didn't fix my problem.

Go into the bios and make sure that virtualization is enabled.

after you enable vt make sure to cold boot
