What happened?

Virtualbox VMs (created using packer) packaged for vagrant worked correctly under 7.1.x, but under 7.2.x they hang at pre-boot screen.

• I've tried 7.2.{0,4,6,8} and all have the same issue.

• I've tried changing the graphics controller to QemuRamFB

How can we reproduce this?

• install vagrant + virtualbox 7.1.x;

• in a directory run vagrant init koalephant/debian12 or vagrant init koalephant/debian13

• run vagrant up --provider virtualbox; notice the box boots fine

• run vagrant destroy -f;

• upgrade to virtualbox 7.2.x;

• run vagrant up --provider virtualbox; notice the box never boots

VBox.log

Did you upload all of your necessary log files, screenshots, etc.?

• Yes, I've uploaded all pertinent files to this issue.

Can you try increasing the VM memory size to at least 1024MiB? It looks like the updated UEFI in 7.2.x has issues with less memory assigned.

That does seem to resolve the issue, thanks.

Would have been nice if the changelog made some mention of the new lower recommended bound though - the UI does warn about this, but with vagrant boxes particularly, it's quite common to never look at the VBox UI.

This was an unintentional change. I think I found the root of the issue, and it looks like a bug. Will try to come up with a fix.

OK, thanks, that's good to know.
