While working through the Fedora virtualization quick start, I ran :
$ lsmod | grep kvm
which should have returned :
$ lsmod | grep kvm
kvm
kvm_intel
Unfortunately I had only, "kvm." The troubleshooting guide suggested running :
$ dmesg | grep -i kvm
Which returned,
$ dmesg | grep -i kvm
KVM: disabled by BIOS
Happy day. I booted into the BIOS ("Press the blue, ThinkVantage button!") and disabled AMT. Unfortunately that didn't do it either. I rebooted again, pressed "the blue, ThinkVantage button," chose "CPU" and enabled the two settings for virtualization,"Intel Virtualization Technology" and "Intel VT-d Feature."After the next reboot all was well.
