I've got a quick question. http://wiki.xensource.com/xenwiki/XenNetworking
says that Xen creates, by default, eight pair of "connected virtual ethernet
interfaces" for use by dom0. Does this mean that

a. If we're using bridging, # of VMs are limited to 8 per physical host
(leaving Dom0)? or this has got nothing to do with the # of VMs running in a
physical host?

b. If the answer to Q(a) is "yes", then how can we have more than 8 VMs
created within a single physical host? Should routing (or any other method
except bridging) be adopted for the purpose of networking in such cases?

Can anyone please clarify?

Thanks in advance,
