I think we have the same issue.

Opencore boots fine, I managed to install until 12/13 minutes remaining, after that tries to boot, but crashes.

Then manual rebooting opencore loads fine there's a option for bigsur macos install select this and at the phase that the apple logo is already up the screen it crashes and can't even see the errors, because it's too quickly something with "sigakill: shutdown...!!!.

Been this week trying to figure this thing out, but no show!

Any clues?

EDIT: Since I can't make any usb to boot in my system, i booted from empty internal ssd, only with EFI populated, after that i use the usb  to make the installation to the internal SSD. Could this be the issue?

HP XW6600, 2xXeonE5430, 16 GB, 256GB SSD, Nvidia 710GT. 

EDIT2: I was able to get a picture of the final verbose, just before the screen become black. Can anyone make something of this, it's not very clear.

Nope!

I installed beta5 from an image from here, and it's working very well.

Unfortunately, until today, couldn't update in anyway.

Still trying to figure it out.

I had been able to boot my Big Sur installer but once I installed it in my hard drive, the installation does not boot or proceed to the desktop. I have used your olarila BS image and yet it does not even boot in my OC. I have done clover as well but all it does is give me MACH reboot or ACPI error. Can you help me with this?

Here is my EFI for OC. You can help me with the clover EFI as well.
