Yay. Actually Murali's commit still doesn't work with XenServer 6.2. Dom0's
VIF plug to GRE network with a warning, but XenServer hosts still doesn't
recognize the network. I also stuck at that point. The problem here is in
one cluster, host A creates GRE network but other hosts don't recognize it,
although the network is still listed in xe network-list command or in
XenCenter. If we deploy only one host per cluster, it works fine.
