Vista - Cant ping virtual server guests from the host machine; VS guest cr

I'm running VS 2005 on x64 2003.. frequently, as of late, despite no
indications of issues in the event viewer.. i run into times where i lose the
ability to even ping the guest OS's, even from the same host machine..

I can log into the VS console just fine.. even click on the guests and poke
around inside them, but all connectivity seems dead..

Ill try to then stop and start the VS service.. it will get hung up on the
last one it saves the state on.. my only recourse is to reboot the whole host
machine.. and frequently even when it reboots, i cant ping the host from
another machine (or at least i think this was also the case).. i pulled the
network cable from the host machine and back in and suddenly it worked,
though even before this, i could ping say at least the internet from the host
machine.. but now host to host ping would work (or so i think this is the
case).. so its almost 2 part here, if this second part is accurate?

I did receive this error message when trying to stop the virtual server
service:


(a bunch of these representing each VS):
VM not powered up. Device uninitialized

(then this error):
Structured exception occurred on an undetermined or a global thread.


Has anyone ever had this sort of communication issue before?

Also.. prior to this, one of my VS machines did show up in VS event viewer..
it said something to the effect of, this VS hasnt responded in awhile it may
have crashed (which apparently it did)..

Thanks

How many VMs do you have connecting to a single NIC? When I've seen issues
like this, it's most often been just too many VMs tied to the same NIC.
Really, the overhead of the emulated virtual NIC in Virtual Server is quite
high, and it can easily get overloaded. Having separate physical NICs for
each VM or at most a couple of VMs, is a lot better way to go.
