Well, another day another bug!
Cisco bug CSCvh55176 for the official page.
I setup Unity connection fresh install on BE6K with ESXi 6.5. VM booted and worked properly, but after restart the VM didn't boot again and had only a black screen with a cursor, no messages, nothing..
A colleague run into this bug before me so I was provided with the resolution below:
You will need to:
- boot VM with recovery ISO
- Once the options appear, press ALT+F2. This will take you to bash prompt.
- chroot /mnt/part1
- /usr/bin/vmware-config-tools.pl -d
- You may ignore the errors at the end
- Exit and disconnect the ISO and make sure you will change the boot order again in BIOS
After above other VMs should be boot as well.
