Hi, i have a ubuntu 14.04 server that has a virtualbox 4.3.36 installed. Couple days ago we had problems with one of our servers, due to a filled up hard drive and during that time i rebooted the host machine, after which i found that the whole virtualbox had dissapeared from the host system.
To fix this i simply reinstalled virtualbox (sudo apt install virtualbox) and everything seemed to work fine after that. Later i noticed that only 2 of the 3 guests on the host had started up, so i tried to stat the 3rd guest manually with: VBoxManage startvm <guest3> and the output i got was:
"Waiting for VM "guest3" to power on... VM "guest3" has been successfully started.
But the guest3 did not start, i checked the Vbox.log and found this error: Power up failed (vrc=VINF_SUCCESS, rc=NS_ERROR_FAILURE (0X80004005)).
This is a very wierd prolem that i have not faced before, doing "VBoxManage list vms", shows all 3 guests and 2 of them work just fine, it is just the 1 that isnt starting up no matter what i do.
Below is full VBox.log of the problematic guest:

After doing more digging i found a log file from at /home/vboxuser/.Virtualbox/VBoxSCV.log and in there:

if im reading/understanding this right, it is trying to open a VM using "{6ade3077-e966-4d63-bb24-1473fbf6832c}.vmdk" but there is no such snapshot in the folder.. is this the problem? how can i change it to look for the snapshot i actually have?
