OpenBSD UEFI install/boot panics.
-
I'm attempting to install OpenBSD with EFI on a new VM instance. Booting BIOS works just fine (blue kernel text) but EFI just refuses to boot the installer.
I've tried the CD ISO installer and I've also tried importing the disk image as a separate VDI. When the installer boots the kernel messages start and then fails after detecting the CDROM. Thinking it might be a OpenBSD7.8 issue I installed the most recent snapshot (trying both ISO and IMG).
I've been able to boot the installer by removing the second VIF (setting VM as a firewall for isolated net) and going into the boot config and using:
boot -c # does boot stuff
disable xbf
quitThe initial panic is:
panic: page full, sc 0xffff800000024c00 gnt 0xffff8000000f8000 (4) ge 0xffff8000000f8078
Is there a config item I'm missing? A google search of the panic values doesn't come up with anything. The seems to be related to EFI grant table sizing but that's a bit outside my wheelhouse.
I was able to complete the boot and install but have to disable xbf each time otherwise it panics (attaching screenshots). Patching to the most recent snapshot doesn't correct it either and I can't add the second VIF without a similar panic. If I patch the boot config to disable xbf it will panic with the second VIF which then also breaks on kernel re-linking.
Any ideas? Is this a Xen issue or an OpenBSD issue?
Not sure where to send this debug details.The xe template-param list is as follows:
