Mojave VM stuck in a start/reset loop just early in boot loop

[petenish]

    I'm a newbie at VirtualBox on a Macbook (10.14.6), trying to create a 
    Mojave VM.  I've gotten as far as the VM gets created, but the
    VM is stuck in a loop as it appears that the boot to Mojave fails
    early in it's initial boot of the OS.  I've tried this with
    10.14.4 and 10.14.6

    And, it might possibly because I'm not quite understanding the
    runMacOSVirtualBox script.
   
    What I had to do was
        - run 'installinstallmacos.py' to build the 10.14.x .dmg installer
        - mounted (via hdiutil) the .dmg
        - create /Applications/Install macOS Mojave
        - create a symbolic link from the mounted 
          .dmg/Install Mac Mojave.app/Contents to 
          /Applications/Install macOS Mojave
        - execute runMacOSVirtualBox.sh

    At this point, the various macOS-VM files/directories are created
    and the VM is started and booted and I get into the loop.

    Of course, the script prompts to eject the installer medium, and
    I do so, and I just get stuck at the Shell prompt because it can't
    find any bootable device.

    Maybe I'm doing something very wrong/dumb (as I thought that I
    wouldn't have to manually mount the .dmg/create the link to Contents),
    or maybe something in my VirtualBox is setup incorrectly.
    Any help/pointers greatly appreciated.

    I've attached a VBox log (VBox.log.2) which seems to show that I'm getting
    repeated "xHCI: Hardware resets" (maybe this is a clue?).

May be related to bug #103.
A bit more info and a video of the failure

Vbox : Version 6.1.8 r137981 (Qt5.6.3)
Extension Pack : 6.1.8r137981
Host : Mojave 10.14.6
Installer : Mojave 10.14.4

10.14.4 reboot loop.mov.zip

Sorry, hit the wrong button - didn't mean to close it

[tigeryu8900]

Try downloading the Mojave installer again and start over. A corrupted installer may cause this issue.

[AlexanderWillner]

Is this issue still valid?

[petenish]

Yes, it's still fails into a reboot loop.
I'm on Catalina now (wanted to try a VB, but gave up waiting) and
running vbox 6.1.12 r139181 (Qt5.6.3). I pulled down -master.zip
again, ran ./installinstallmacros.py and selected '4' (10.14.4 Mojave),
ran './runMacOSVirtualbox.sh all' and the resultant VB image just gets into
the same reboot loop.
Is there something more that I can provide, or help debug this problem?
Anyone else having this problem?

[petenish]

Hit wrong button. DIdn't mean to close this.
