Creating a LAG between an ESXi vSwitch and a Physical Switch

Sunday, October 30th, 2011

In this lab I am going to create a LAG (Link Aggregation Group) between an ESXi vSwitch and a physical switch. You can use Cisco, Force10 Dell, Juniper, or any other manufacturer for the physical switch. Depending on the switch you use, the commands may vary on the physical switch for creating a LAG (referred to as port-channel by Force10 Dell and etherchannel by Cisco). I will not get into details of creating a LAG; please reference my earlier posts Creating a Link Aggregation Group (LAG) in FTOS and Setting up Cisco EtherChannels – Static, PAgP, and LACP for this information.

Once I screen scrape to get the relevant website, I am able to send a specific request to the server to obtain further information. (more…)

ESXi 4.1 on top of Fusion on Apple MacBook Pro

ESXi 4.1 on top of Fusion on Apple MacBook Pro

I have been messing around with VMware ESXi on my Apple MacBook Pro laptop for a while now. Actually, I have installed ESXi on top of VMware Fusion. Further, I networked everything together so my Apple MacBook Pro can communicate with ESXi and the Virtual Machines (VMs) installed on ESXi as well as the VMs installed on Fusion. (more…)


VMware VI SDK – guestOsId values (VirtualMachineGuestOsIdentifier)

Tuesday, October 18th, 2011

I was creating some Virtual Machines using the Java VI SDK and needed the respective values for the VirtualMachineGuestOsIdentifier (abbreviated by many as guestOsId). I realized many people are searching for this information but have trouble locating it simply because they don’t know where to look. Posting here to save anyone searching the trouble.
