Autolab in VMWARE Workstation 8 on Linux

Posted: July 5, 2012 in Uncategorized

I’ve just been deploying Alistair Cooke’s awesome Autolab into VMWARE Workstation 8 on Ubuntu. Now, linux is a bit of a new beast for me, being a long time Windows guy, but we’ve all got to broaden our horizons now and then.

As I was registering the pre built VM’s a warning popped up about promiscuous mode not being able to be enabled. Not paying full attention and being keen to get a lab up and going, I ignored the warning and carried on.

The lab progressed smoothly until I went to add the hosts to the VC and saw this warning in the powershell script that adds and configures the hosts. I’d chosen the full autmation including deploying a nested guest.

After a quick bit of investigation with the first tool of choice (ping) I quickly came to the conclusion that there was something not quite right on any network using vlan’s. Having hit this before in my lab that I built for VCP5 practice and the faint memory of a warning earlier on in the day,  I went a googling.

Very quickly I found this VMware kb Effectively Workstation configures permissions for vmnet0 through to 3 to only allow root to enable promiscuous mode, which you need turned on for nested esxi with vlans configured, to work.

The moral of the story, do one thing at a time and pay heed to warning messages.
