This may be because you have reached the limit of the number of interfaces
that the loopback driver supports. If the loopback driver is a module, you
may raise this limit by passing it as a parameter (nloopbacks=<N>); if the
driver is compiled statically into the kernel, then you may set the parameter
using netloop.

I googled around for awhile looking for similar problems...since most people start pointing at network card drivers etc...
$ lspci | grep net
00:08.0 Bridge: nVidia Corporation MCP55 Ethernet (rev a2)
00:09.0 Bridge: nVidia Corporation MCP55 Ethernet (rev a2)
what module should be loaded for this card?
Internet does work fine on this system.

this instructions get past that problem and get the guest to start:
http:// www.nabble. com/Veth0- missing- t3148102. html
so it seems that the problem is with the network-bridge script and/or with the process of creating the bridge with brctl
