Ubuntu smp problem :(

[diogenese]

I've set up a second VMware ubuntu machine to use all 4 cores and that's crunching fine but now my old VM won't crunch I've tried to reinstall manually and now I've done a fresh finstall and I get the same error.
Help!

I can't see it as an OC problem, the other VM is running fine.
I have two VM's running, one called ubuntu and on bridged network ID ***.*** .1.7 and ubuntu2 on ***.***.1.8. Both connect to the web OK, both do other tasks fine but the original one won't crunch even with a fresh finstall.
I might try loading up another VM and binning the first if I can't get it to work again
The OC is very small ATM, just running it in a bit 300 fsb from 266

I've copied the folder from a working client to the dead one, now I get this.

What is MPI and how do I fix it?
I wish I knew what I was doing with linux rather than blindly following guides

Cheers for that sculptor, the second one had the answer well almost but it showed up the problem!
Somehow ( no idea how/why) the network address came up as ***.***.1.8 for ubuntu instead of 1.7 which it started out as.
In system/administration/network/connections the address came up as 1.7 but in the hosts tab it was 1.8, the address of the other VM
I changed it in hosts and all's well
