Stop your eth2 NICs from autonegotiating with the appropriate driver 
options in modules.conf, modprobe.conf, /etc/modules or whatever your 
distro uses. If they're 100 meg cards, force them both to 100BaseTX-FD; 
for gig cards force them to 1000BaseTX-FD.

It sounds to me like you've got both ends of the link continually 
renegotiating, which will mean a certain amount of errors - although 
they may retransmit at L2, it might mean you get L3 timeouts on occasion.

Inside your VMs you won't have this problem (obviously) unless you're 
running on two VMWare host servers with a corresponding physical problem.

You can fiddle with the card settings by using mii-tool in real time.
