Re: [Astlinux-devel] Console in a VM

[Lonnie A. <li...@lo...>]

David, sorry to hear that.  I know I have switched back and forth between Legacy and UEFI BIOS in the past in Proxmox.

The ISO installer must be done via Legacy and switch later to UEFI if desired, which I have done.

Very surprised to hear your results.

Lonnie

I did a shutdown -h in astlinux, changed proxmox settings for the VM to use UEFI, restarted the VM and bad things happened.  First, opening the console just displayed a message that Guest has not initialized the display (yet) and it just stuck like that.  Worse, I could not ssh in... and it never responded to pings.  So I shutdown the VM again from proxmox, changed the bios back to the SeaBIOS, and rebooted.  And it failed... console reported that it could not find a bootable disk, it tried to boot from the network.
