Thanks for catching this.
While we're at it, why not remove the 2 occurrences of re.IGNORECASE
that have no effect?
We can also replace re.search(regex, o) with the slightly shorter
regex.search(o), but that's just a cosmetic change.

Subject: [PATCH] KVM Test: Add re.IGNORECASE to re.compile to verify_ip_address_ in kvm_utils.py

Since the mac address is (changed to) lowercase and the output of
'arping' is in uppercase, we need re.IGNORECASE in the re.compile.

(the re.IGNORECASE in the re.search function takes no effect on the
compiled regex.)
