Save State stuck at 0% since recent update (Arch Linux, Vbox 7.0.16r162802)

[hans.werner]

Problem Description

Since last update a week ago (or so) I can not save the win11 state (running -> save). However, I can save the state of all other machines (Linux, Win Server 2003, 2008, 12 etc). When I am saving it does not matter, e.g. during guest reboot or after running the guest a few min or anything else. It is just stuck at 0%. Logs and Debug are NOT showing any information (except SUSPENDING -> SUSPENDED -> SAVING) Cloning the machine, reverting to previous snapshots, making more disk space on host or things like that, and then trying to save the current state does not work either. Exporting and Reimporting does not work either.

uname -a

-> Linux 6.8.7-zen1-1-zen #1 ZEN SMP PREEMPT_DYNAMIC Wed, 17 Apr 2024 x86_64 GNU/Linux

cat /etc/os*

-> arch/rolling

vbox --version

-> 7.0.16r162802

Tried solutions:

• Reset to old save state and restore (doesn't fix anything)
• Deleting old save state (doesn't fix anything)
• cleaned up disk space (122 GB available, 40 GB vdi sizes) && Resizing HDD/Medium (vboxmanage modifyhd/medium win11.vdi --resize <size in mb> -> does not help)
• Full Machine Export/Reimport (Appliance)
• Deleting all snapshots and nvram file (or moving them out of the folder and resetting the state -> no success)
• full device reboot
• full device update

Once the saving process is started, it is unstoppable, except by forcefully terminating it e.g. by running sudo kill -9 $(pgrep -i vbox && pgrep -i virtualbox)

BTW: Log file does not indicate anything special but it is attached.

/Edit:

Problem seems prevalent in version 7.0.18-1 (host-dkms, vbox and guest-utils)

I did a pacman -Syuuu and general update and saw this:

• virtualbox-guest-iso-7.0.18-1
• virtualbox-host-dkms-7.0.18-1

I'll test it now, looks promising.

/EDIT: Never mind, it's still broken.

pacman -Q | grep virtualbox

• virtualbox 7.0.18-1
• virtualbox-guest-iso 7.0.18-1
• virtualbox-host-dkms 7.0.18-1

Interestingly, it works after killing it (see above) as long Win 11 is not loaded, see ss below. Maybe a bug in Guest Additions? Too much memory to save? IDK - Logs are telling NOTHING.

added hint regarding 7.0.18-1
