I found this in one of my older projects. And I felt it.
I've been developping some software so an entire debian OS gets bootstrapped and installed with all the desired software with the help of puppetlabs software...i need to prepare a server that can handle virtualization and be fast at it. So all the goodies a decent server needs, the apt, caching, networking, firewall, everything checks out... I want to test kvm virtualization... Doesn't work. Wtf? Spend a decent amount of time figuring out what the hell is wrong... I finally dzcide to think 'what if my buddy accidentally gave me a bad mobo'...
$ grep -e (vmx|ssm) /proc/cpuinfo
Nothing...
I feel so stupid to not check the mobo virtualization capabilities.
