This is a common problem with ESXi. Though vmware include most of the well known network driver, still its has some limitation.
During my installation I found hat atheros network adapter was not recognize by the ESXi.
So shall i stop here ? No not at all.
What we need to do ?
1) extract the Original ESXi ISO image
2) Include the Atheros network driver for ESXi
3) Build new ISO
And we are good to go.
Find out your network interface card. During the installation, you can always do Alt+F1 and type
# lspci | grep -i net
00:03:05.0 Network controller: Atheros AR8132 Fast Ethernet Controller
Search for ESXi driver file (try google)
I found here
Download the ZIp file or .vib file of the driver.
Download the ESX customiser, its an easy tool to extract and re-build the ISO, including the driver.
And just follow the instruction.
Boot the server with newly build ISO image and see the magic 🙂
