virtualbox gui doesnt start any vm after deleting a snapshot

[Zsombor]

VirtualBox GUI does not start VMs after deleting a snapshot.

I also deleted the corresponding VM as I've read ticket #1734 but it did not help. There is no cross-reference between machine and harddisk UUIDs. The error also occurs with the newly created VMs, also if they don't have any harddisks. VirtualBox.xml seems to be valid.

• All VMs can be started from command line with VBoxHeadless

• All VMs can be started from command line with VirtualBox --startvm <machine> (!)

• VMs can be created, deleted, changed from the standalone GUI, only starting them fails (see attached snapshot)

• This failure does not create log entry.
