Cannot start ANY VM...

[dargaud]

Hello all,
I had a snafu trying to increase the size of one of my VMs, and now none of them work. Trying from backup fails. Trying importing a working .ova fails. Even erasing them all, creating a new one WITHOUT HD and trying to start it results in:

Code: Select all

Failed to open a session for the virtual machine test.
The virtual machine 'test' has terminated unexpectedly during startup with exit code 1 (0x1).
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: MachineWrap
Interface: IMachine {f30138d4-e5ea-4b3a-8858-a059de4c93fd}

What is going on ?!? How do I completely clear VirtualBox settings ? I removed ~/.VirtualBox and ~/VirtualBox VMs/ and still it fails launching an empty test VM. Host is Ubuntu 64.

You removed the folder that contains all your VMs??? i.e. ~/VirtualBox VMs

[dargaud]

Well I removed the VMs from the interface, so the directory ended up empty; I then created a new empty VM and still that failed.

[loukingjr]

I have no idea what an "empty VM" is or how it would start seeing it's empty. But that's just me.

[dargaud]

Create new VM, do not define a HD. At least you should see the pseudo BIOS message. It fails before that.

[loukingjr]

At least you should see the pseudo BIOS message.

Why? You decided this based on…?

[dargaud]

Fine. If I attach some simple LiveCD iso, same thing, it fails before it displays anything.

[loukingjr]

That's actually never happened to me in 6 years.

I noticed that the vboxdrv service was dead (even after a reboot), so I started it manually and, surprise, I could start my VMs. As to why it dies...:
