Starting last night, with no apparent changes to my system, VirtualBox now freezes my host OS when starting any virtual machine.
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. It was working properly last night, but as of this morning, starting the VM freezes. I pulled it from the apt
repository just this morning. It is very unlikely to be a software issue, as I reinstalled the host OS this morning.
I tried a number of things:
- I tried creating a new VM, but it freezes immediately as soon as you select the ISO to mount.
- 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. But still, it freezes the host as soon as you load a VM. Any VM seems to cause it.
- 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.
And because it’s happening also on another laptop from another vendor, I doubt it's a hardware-related issue. And because happens on even a blank VM install, it isn't anything to do with a corrupted image.
I’m stumped and I don't have any idea how to debug this. And the fact that it freezes my system also makes it very difficult to iterate through possible solutions.
pti
option as per that thread's suggestion. I verified it was off, then tried again. Still froze :(
