Network is unreachable?

I’m running Workstation 8.0.1 on a Linux Mint 12.0 host (basically, it’s Ubuntu, with some GUI changes).

I’ve been running a Linux Mint guest, under that, for some time, without difficulties.

Today, I was playing around with vmrun, trying to see if I could use it to suspend the Ubuntu guest.  Suspend and Start both seemed to work fine, except that when the guest came back up, it had lost the ability to connect to the network, Running ping from a command-line in the guest returns “connect: Network is unreachable”.

I restarted the guest, then restarted the host and the guest, I reinstalled the VMware tools, all to no effect.

I had been running in Bridged mode, I switched to NAT, and still nothing.

I’m at a loss.  Any ideas?

Just as an update: I copied the .vmx from a backup, in case something had been changed.  No difference, networking was still disabled.

So I restored from backup, and that networking worked fine. Ran the current version again, and networking is still broken.

I’m at a loss as to what might have happened, but I’m thinking the best solution might be to copy off the files that have changed, and then do a restore.
