Thank for the patch.
I will care to integrate.

Appart of the typo, maybe we could detect boot from KVM?

http://www.dmo.ca/blog/detecting-virtualization-on-linux/
say 'dmesg | grep -i virtual' detect for all virtualized cases.

To be specific for KVM, I suppose this should do the trick.
dmesg | grep -i 'paravirtualized kernel on KVM'

Could you confirm?
