That card is *old* -- it brings back memories. :-)  And, 3Com is gone. Is
there any FOSS support for 3Com stuff?

This is one of the classic fast-ethernet cards, supported by the original
Beowulf cluster implementation:


One would expect that any bugs left in the kernel driver
(net/ethernet/3com/3c59x.ko) would be hammered flat by now.

I'd wonder if it's reached the point tha that the hardware is failing. At any rate, a generic realtek gigabit card (free after rebate!) will run rings around what was a good card in the late 90s but functionally obsolete today.

Back to the original config: did you know you could add the built-in adapter to the bridge, give your IP address to the bridge rather than directly to the built-in interface, and use the VMs the same way you are now without a second NIC?
