Virtual Switch on Teamed NICs = slow VMs?

-

 

wonder if has seen or might able suggest troubleshooting pointers.

 

i have hyper-v evaluation system. the hardware dell poweredge 2950:  2 x dual core 3.0ghz xeons, 32gm ram, 2 internal broadcom netextreme ii nics, 1 intel pro 1000 pt 4-port nic card, external sas array (dual channels, 14 disk raid 10).

 

os rtm w2k8 standard x64.  hyper-v in-the-rtm box version.

 

i have run while using 1 of internal nics system's nic , other nic virtual switch bound to.  once intel released w2k8 drivers, installed , set intel card 4 port team , created new virtual switch , bound intel team.

 

then fired vms , found vms multiple virtual nics unresponsive.  clicks take forever responded to, windows open molasses, etc.  vms respond pings though without issue (~4000 1 lost <1ms response time).

 

the vms in question using w2k8 standard x64.  (these dual nic'd vms testing exchange 2007 rollout in case curious -- ht servers, mb servers, , cas servers...)

 

these configs worked fine solo nic virtual switch.  ideas on look?  have forgotten provide useful clues?

 

thanks in advance advice or smacks upside head!

generally speaking if function correctly without teaming driver present - not work teaming driver present - 99% bug teaming driver.  using standard ndis interfaces under windows our thing.

 

cheers,
