Proxmox KVM kernel module: No such file or directory

Hit by this little bugger this morning, while trying to move a virtual machine from proxmox 3.4 to 4.4.  This was the only VM on the machine, so I was surprised. (Never seen this before)

Could not access KVM kernel module: No such file or directory
failed to initialize KVM: No such file or directory

I know CPU’s must support (Intel’s) VT (or AMD-V) but that’s mostly on by default ? Seems for this machine it wasn’t. You can check your CPU using :

grep flags /proc/cpuinfo | grep --color vmx

If you have those flags, its most likely virtualization is disabled in the bios. I rebooted and changed the bios setting to ’enabled’ and voila problem solved!
