Installing KVM VirtualMachine Manager in Ubuntu 12.04 LTS or Greater
1.To Check Weather the System Support for Virtualization we need to check using
# egrep -c '(vmx|svm)' /proc/cpuinfo
Note
If 0 it means that your CPU doesn't support hardware virtualization.
If 1 or more it does - but you still need to make sure that virtualization is enabled in the BIOS.
2.To see if your processor is 64-bit, you can run this command
# egrep -c ' lm ' /proc/cpuinfo
3.Now see if your running kernel is 64-bit, just issue the following command
# uname -m

# sudo apt get update
