I am using Home Assistant virtual machine on Vmware for very long time. It always worked reliably. But now, suddenly, without any changes, it fails to boot with

"The firmware encountered an unexpected exception. The virtual machine cannot boot."

See the screenshot:

See screenshot I haven't changed anything, neither on host pc, neither on guest virtual machine. I tried following information from web saying that I should add this line to vmx file:

pciHole.dyn = "FALSE"

but nothing changes.

I have no idea what to do any more. How to unlock this vmware machine and furthermore? Why did it even fail, as I haven't changed anything?

PS: Other vms are ok

  • Update the Host BIOS and make sure VT-d Hardware Virtualization is (remains) enabled. I am using VMware Pro V 16 newest here with no issue. – John Jun 10 '22 at 12:37
  • After the updates to correct firmware issues (Host) you still have an issue, make a new test build of the VM and see if it works. – John Jun 10 '22 at 13:50
  • @John I don't know what happened, but (yesterday) after few hours, without even restarting the PC, it suddenly started working again. I have no idea why. I will keep the question open in case that happens again. Very strange. – Benjamin Rutford Jun 11 '22 at 06:42
