Running VMS on Linux

By the end of this tutorial you will have working virtual machines using KVM on Linux

Check if virtualization is enabled

Run this command:

1
egrep -c '(vmx|svm)' /proc/cpuinfo

If the output is greater than 0, then you are good to go
Otherwise go into BIOS and enable virtualization
