Has anyone else experienced this? I wanted to try out the Big Sur beta, but didn't want to risk rendering my daily MBP unusable.
Thanks!

On a real, supported Mac, run this command in Terminal:I was able to get past the "BIErrorDomain error 3" issue in Parallels as follows:
Create a new Parallels VM by installing a fresh copy of macOS Catalina from Recovery Partition (or use existing VM).
DO NOT INSTALL Parallels Tools or uninstall it if it's already installed.
Login to iCloud account which have Apple Developer Program membership active (thanks @paulrbarnard).
Resize disk drive to be at least 80 GB (see article 112119 in the parallels knowledge base website on how to do that).
Download and install your Beta profile (https://developer.apple.com/download/).
Code Block sysctl hw.model
Code Block ioreg -l | grep board-id
Code Block devices.mac_hw_model="mac_hw_model" devices.smbios.board_id="board_id"
Make sure you have no Parallels Toolbox installed
Add a second account to your Mac. Don't log in.
Install Big Sur
Login with the second account
Before creating Catalina VM don't forget to resize disk size to 80 GB (at least)
Format 80 GB disc with using APF format before starting Catalina installation (otherwise you cant use 80 GB)
After Catalina VM installation start necessary update from Software Update, version will be 10.15.5
Copy "Install macOS Beta" (9 GB SUR installation file) to the Applications
Create 2nd Admin user and leave password blank (you will use it while login to SUR)
Don't install Parallels Tools
Copy current Catalina VM to external disk as a backup
Complete below process (run Terminal on the real MAC not VM)
Shotdown the Catalina VM and put above two lines to the In the VM configuration, under Hardware -> Boot Order -> Advanced Settings -> Boot flags
Start Catalina VM again login with standart user (not login with the new created account)
Run "Install macOS Beta" from applications (copied SUR Installation file)
Wait approximately 45 mins. login with new account
Thats all
yea that is happening to me as well. I did go Mojave-> Catalina -> Big Sur and I'm running my VM in VMWare ESXi on a Mac Mini 2018. Nothing seems to work.I enter my password, login, the system spins for a little while, the screen goes black and then it is back to the login prompt
Create USB install media: createinstallmedia --volume <path to usb>
Create New VM from USB drive and customize before install: set Boot flags as suggested above (devices.machwmodel AND devices.smbios.board_id). Disable Parallels Tools autoinstall.
Complete the install process
