discarding the "saved state" of the virtual device using the online box GUI allowed me to launch the Ubuntu VM.

Just best click and choose "clear conserved state" come restartor click on the orange discard icon.

You are watching: The vm session was closed before any attempt to power it on.

I resolved it solving filesystem permissions, there to be in a weird state by doing as root (or sudo):

find /pathToVmDir -type d -exec chmod 755 +find /pathToVmDir -type f -exec chmod 644 +The state was:

usr
machnine:~$ ls -l /mnt/data/virtualboxVms/ <418/418>ls: cannot accessibility "/mnt/data/virtualboxVms/vmDebDev": Permission refuse ls: cannot access "/mnt/data/virtualboxVms/Archiv": Permission denied full 0 d????????? ? ? ? ? ? Archiv d????????? ? ? ? ? ? vmDebDevJava_Clone

It to be a permissions problem for me because I adjusted the VM folder come a various drive, either try running as administrator or just readjust the security permissions that the VM source folder to allow full control by anyone. The latter operated for me!

My systems was to clone the VM into an different name, and also then remove the larger one with all the files.

(I currently removed the Snapshoots and VM in every method I believed ...)

I newly installed VirtualBox and try to register a former developed virtual machine.When begin it I got the exact same error. And also the "clear conserved state" was not-able-to-click. I tried other virtual machines, every the same.Then ns did this:1)I enabled the CPU virtualization in bios, which to be disabled. (not yes, really related yet should give an additional 64 cpu no supported choose error sooner or later).2)I remove and save storage tough disk. Then an additional error:

............(Access denied.)..........3)Reopen virtual box in Administrator. Or probably repeat 2.it works...

I challenged the exact same problem. I resolved it by renaming the .sav file. Measures to settle the problem.

Select the VM i beg your pardon is having problem and Right click VM and also select "show log" option

Go the path where the .sav document is situated and adjust the file extension come anyother file format.

Restart the VM. The works.

I hope this prize isn"t too late, but I remained in the exact same problem and also finally I addressed with two solutions gain from various sources.

You need to solve the next problem with:

Open the registry editor. Start > operation > regeditGo to: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesVBoxDrvEdit the crucial called Start. Readjust its worth from 1 come 3Close the it is registered editor and also restart your computer. ~ your computer system restarts you should be able to use VirtualBox without any issues.

If not you need to open cmd as Administrator and type the next command:

sc start vboxdrv

After that try to start the digital machine.
