A Windows VM crashes when starting a group

[D. Bugger]

Hi,

This is mostly for the developers... who are doing a great job by the way!

My host system is Ubuntu Linux 22.04 LTS, ample disk and memory, with VirtualBox 7, all regularly updated. Sometimes, when I start a group of VMs (two Windows-10 systems in my case), one of them crashes, for reasons unknown to me. I sent the crash report back, to Ubuntu (I assume). When I start the crashed VM again, or when I start VMs one by one, all is fine.

That's all folks!

We had another report where starting two VMs at the same time had a crash in one of them. Delaying one VM's start until the other was up and running was the workaround. We didn't determine why the problem happened. I surmised that something Virtualbox needed to start a VM couldn't run twice at the same time.

But if starting a group has this error, the devs should hear of it. Please post this in a Bugtracker ticket. Maybe the crashed VM's vbox.log and the main VboxSVC.log, zipped, might help them too.

I'll report it properly, when it happens again (like this morning).
By the way, there's no such thing as an automatic delay, configurable somewhere, I suppose? No need to reply if there isn't...

Thanks!

No automatic delay, no. But you can write a script with Vboxmanage commands to start each VM with a pause between, then use the script to start the group instead of the main Virtualbox window.
