Running VMware ESX 3.5 in VMware Workstation 6
VMware ESX 3.5 was released some times ago.
Yesterday I have a time download a latest VMware ESX 3.5 and I have installed VMware ESX 3.5 in Workstation 6.
As usual, I believe this shouldn't be any problem for me. The installation go smooth but when I want to start the VMware ESX 3.5, it took me more than half day to get it up. Again, I'm still having a problem with login, networking problem, and etc as you can see from as image attached.

ESX Host Currently Has No Management Network Redundancy Error
After upgraded to virtual center version 2.5 recently, I found an error message "host ESXhostname currently has no management network redundancy" when I tried to create a new cluster with 2 ESX hosts.
My test setup has one service console & one VMkernel connected to vswitch0 with single network card for both ESX host. The funny part is the problem only happen in one of the ESX host instead of both. I believe somehow this is due to my network design/setup in my test environment.
Again the similar error posted in VMware Communities forum solved my problem.
