Description of problem:
I've got a hosted engine up and running on a freshly installed 
3.5 host (CentOS 6.6), and I'm tyying to add a second host. The 
install fails trying to configure the ovirtmgmt bridge:

[ INFO  ] Updating hosted-engine configuration
[ INFO  ] Stage: Transaction commit
[ INFO  ] Stage: Closing up
[ ERROR ] Failed to execute stage 'Closing up': Cannot acquire bridge address

Version-Release number of selected component (if applicable):


How reproducible:
every time


Steps to Reproduce:
1. set up hosted-engine on 1st host using vlan
2. try to deploy on second host with vlan suing name of the form ethN.V
3.

Actual results:

Expected results:
setup succeeds

Looking at setup logs, you have: OVEHOSTED_NETWORK/bridgeIf=str:'eth1.79'

and when it try to get the ip address for the interface:

which seems to fail matching REGEXP:

    _ADDRESS_RE = re.compile(
        flags=re.VERBOSE,
        pattern=r"""
            \s+
            inet
            \s
            (?P<address>\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})
            .+
            \s+
            (?P<interface>\w+)
            $
    """
    )

I guess the match is failing due to the '.' in 'eth1.79'
