HI, there,
Just encounter the problem that need help.
In deleting a snapshot while guest running, it turns out to crash the guest and never can be started again. It runs on rhel 7.3 with virtualbox 6.0.14. Guest OS is Redhat coreos. Please see the crashing output while deleting snapshot as below:
---------------
Deleting snapshot '4.2.7' (8b8a28dd-9138-456b-bd7e-c02e8476167a)

Deleting snapshot '4.2.7' (f522d4eb-4db1-420c-8c6c-320511bac317)

Then I tried to delete the snapshot(4.2.7) again, that succeed with no time. Tried to restart the guest but failed with error below:

---------------
For not starting, just tried to restore another snapshot(4.2.18) but hangs at 60%.
Now all VBoxManage command will hangs in no time.
I would like to restore the guest to live. Any help will be much appreciated.
Thanks a lot
Ben
