alexanderbazhenoff a87acf93d8 kvm: improved performance on creating VM (#2923)
Improved performance on creating VM for KVM virtualization.

On a huge hosts every "ifconfig | grep" takes a lot of time (about 2.5-3 minutes on hosts with 500 machines). For example: ip link show dev $vlanDev > /dev/null is faster than ifconfig |grep -w $vlanDev > /dev/null. But using ip command is much better. Using this patch you can create 500s machine in 10 seconds. You don't need slow ifconfig prints anymore.
