ESXi – stuck at Relocating modules and starting up the kernel

This situation happen when I tried to install ESXi 6 update 2 on Sun Fire X4150. Here are steps how to solve this problem with video subsystem where Sun Fire server has low memory than ESXi counts with.

  • When booting installation press TAB to edit boot options and insert “ignoreHeadless=TRUE”
mboot.c32 -c boot.cfg ignoreHeadless=TRUE
  • When loading installed ESXi press Shift+O and edit boot options again with “ignoreHeadless=TRUE”
  • To persist booting with ignoreHeadless – enable SSH and logon as root via SSH to ESXi host. After run command:
esxcfg-advcfg --set-kernel "TRUE" ignoreHeadless
  • To check if you have correctly configured persistent ignoreHeadless run:
esxcfg-advcfg --get-kernel ignoreHeadless
