My virtual machines are getting high number of incoming / outgoing HTTP connections. I was experiencing poor network performance and sometimes even total network loss. When figuring out this problem, i updated to 1.x -> 2.0.1 which solved network problems (i think they were NAT related and fixed in 2.0 -- good!). But even in 2.0.1, when running ifconfig on linux guest (Debian 4.0) , it shows:
RX packets:1686882 errors:1666565 dropped:0 overruns:0 frame:0
TX packets:1627982 errors:0 dropped:0 overruns:0 carrier:0
However, guest(s) still runs fine and errors doesn't seem to affect at all. I modified .vmx -file to force network adapter to e1000 compliant mode and the errors where gone.
Is there any performance loss using e1000 driver, or should i use vmxnet? What causes those errors?
