Hello,

yesterday I tried to get UCARP (http://www.pureftpd.org/project/ucarp) working with
a CentOS 6.4 VServer guest but kept hitting the problem:

Apr  7 15:55:50 ha1 ucarp[27635]: [ERROR] Unable to open raw device: [Operation not
permitted]
Apr  7 15:55:50 ha1 ucarp[27635]: [ERROR] Unable to find MAC address of [eth0]

I have tried giving NET_RAW and NET_ADMIN capabilities to the guest but that still did
not work.  On a long shot I even tried ~HIDE_NETIF in nflags but that did not help at
all.

Any thoughts ?
