Hi.
Please look this [code fragment|https://github.com/apache/cloudstack/blob/87ef8137534fa798101f65c6691fcf71513ac978/plugins/hypervisors/kvm/src/com/cloud/hypervisor/kvm/resource/BridgeVifDriver.java#L242]:
{code}
if (brNameMatcher.group(1) != null || !brNameMatcher.group(1).isEmpty()) {
{code}
if brNameMatcher.group(1) is null, method isEmpty will be called, so null pointer exception is happened,
Probably, is should be:
{code}
if (brNameMatcher.group(1) != null && !brNameMatcher.group(1).isEmpty()) {
{code}
Similar code:
