It is pretty easy to get VMWare ESX installable working on a GX280. Boot from a CD burned from the ISO, and hit tab at the first prompt.
Add nocheckCPUIDlimit as a boot option. Here is the whole string:
mboot.c32 vmkernel.gz nocheckCPUIDlimit — binmod.tgz — ienviron.tgz — cim.tgz — oem.tgz — license.tgz — install.tgz
Proceed with the install.
When the system reboots, you will get an error message about the CPUID. The boot option needs to be changed again on the installed system.
Boot from a linux livecd (I used Ubuntu 8.04 desktop), and navigate to the “HYPERVISOR1″ partition. Edit boot.txt
Add the boot option there are well:
kernelopt=nocheckCPUIDlimit
Reboot and it should start right up.
Then connect to the server with VMWare Infrastructure Client
Click on the server name, then the Configuration tab, and advanced settings.
Click on VMKernel and uncheck the VMKernel.Boot.checkCPUIDlimt checkbox, and hit OK.
Now you can reboot it in the future without problems.
