A black boot window pops up right before the freeze.ĭeeper in the bug report you can see issues connected directly to VirtualBox 5.0.40 with the recommended solution being to use VirtualBox 5.2.x. With Kernel 4.13 (from linux-generic-hwe-16.04-edge), the host system freezes completely when starting a VM using VirtualBox. It seems to me you have been bitten by the error reported here titled “Host with kernel 4.13 freezes when starting a VM with VirtualBox”: So you are running VirtualBox 5.0.40 from the default Ubuntu apt repo, correct? The problem is some software packages in repos are out of date and are not regularly updated. It is very unlikely to be a software issue, as I reinstalled the host OS this morning. I pulled it from the apt repository just this morning.

And the fact that it freezes my system also makes it very difficult to iterate through possible solutions. I’m stumped and I don't have any idea how to debug this. And because happens on even a blank VM install, it isn't anything to do with a corrupted image. I have also tried installing VirtualBox on another laptop, and it has the same behavior: Freezing the host OS instantly as soon as any VM is started.Īnd because it’s happening also on another laptop from another vendor, I doubt it's a hardware-related issue.But still, it freezes the host as soon as you load a VM.

I tried a reinstall of the host OS this morning, thinking maybe I was having issues with running out of space on the hard drive.

I tried creating a new VM, but it freezes immediately as soon as you select the ISO to mount.

It was working properly last night, but as of this morning, starting the VM freezes.

The host OS is Ubuntu 16.04 LTS 64-bit as is the guest OS and the version of VirtualBox is 5.0.40_Ubuntu r115130. Starting last night, with no apparent changes to my system, VirtualBox now freezes my host OS when starting any virtual machine.
