Virtualbox creates small logfiles in my home-dir when resuming/suspending VMs

Squiggy · May 3, 2026, 9:19am

Hello hello

My virtualbox (7.2.8) seems to be creating logfiles whenever I either suspend or resume any VM.
I’ve experienced this behaviour on Fedora/KDE, LMDE7 and enOS/Cinnamon, both on my second HDD and system SSD. It also happens after creating a new VM and suspending it.

The logfile:

The “best” result from googling the issue was “seems this is a rare bug”, however those posts were very old and may or may not apply in the present day. Would appreciate it if someone knows what the heck is going on. virtualbox didn’t use to do that just a few weeks ago…

My guess is that some debug code wasn’t removed before it went live. At least it’s just an annoyance.

it looks like a fix in the works:

### Version 7.2.8 ### Host OS Type Windows ### Host OS name + version Windo…ws 10 ### Host Architecture x86 ### Guest OS Type Windows ### Guest Architecture x86 ### Guest OS name + version winXP x64, but that is not relevant ### Component Unspecified ### What happened? While digging into #638 i noticed two peculiar files in my user home directory. * C:\Users\XXXXX\2026-04-22-12-51-33.046-VirtualBoxVM.exe-16700.log * C:\Users\XXXXX\2026-04-22-10-49-44.015-VirtualBoxVM.exe-18396.log Nothing very interesting inside, but they were silently stored in the user home folder immediately, which is somewhat unexpected and certainly not what was specified in "global files" at https://docs.oracle.com/en/virtualization/virtualbox/6.0/admin/vboxconfigdata.html It would be nice if they would be moved either into %TEMP% folder (where mantainance procedures are expected to find and remove residual garbage) or into `.VirtualBox` or into `{Virtual Machine Name}\Logs` as specified in the manual, if they are worth being persisted. [vbox_crash_user_home_wrong_folder.zip](https://github.com/user-attachments/files/27054515/vbox_crash_user_home_wrong_folder.zip) Hope the specific content in the logs would help you finding the neglectful place in the sources that creates temporary files into unexpected undocumented places ### How can we reproduce this? Run any VM after having installer broken drivers installation ### Did you upload *all* of your necessary log files, screenshots, etc.? - [x] Yes, I've uploaded all pertinent files to this issue.

Oh cool, seems I didn’t search in the right places since I didn’t consider windows to also be possibly affected by this. Guess I’mma just wait for the update then and stop worrying that it’s on my end. Thanks
