I'm also seeing this problem on 8.10 after installing the open-vm-tools package and modules from open-vm-source. This seems to be somewhat related to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/209377 . Looks like both vmxnet and pcnet32 are loaded earlier in the boot process, but because pcnet32 already holds eth0, vmxnet gets nothing at that time. However, this leads to a problem in the init script because it will do "modprobe vmxnet" which is a no-op since vmxnet is already loaded.

The following appears to in the init script work:

ifdown --force eth0 # probably should use -a but I had only one interface
modprobe -r pcnet32 vmxnet # remove pcnet32 and the vmxnet instance that doesn't have any interfaces
modprobe vmxnet # vmxnet will now be reloaded and get the interface; eth0 is automatically ifup'd
