Sorry for the SPAM!!!
With the information you have sent I only can guess...
Have you checked, inside EXSi, your GISVM virtual machine settings?
Does it include any virtual Ethernet Card?
Or does it have more than one Virtual Ethernet card?
GISVM server is configured for a single ethernet card (eth0) virtual machine.
So, my first advise to solve your problem is to change, inside EXSi, the GISVM Virtual Machine settings to a single ethernet card, the one you want to use!
To start up, you probably should also try running GISVM Server on your desktop, with VMWare Player...
Hope this could be of any help!
