Virtualbox crashes with VT-x enabled. Usually I get to "Loading 0%", and my whole system freezes up. I've enabled the ctrl-alt-bksp shortcut, but that doesn't even respond.
It works just as expected when VT-x is disabled.
First, I removed the KVM kernel module:
sudo apt-get purge kvm
sudo dpkg -P kvm
modprobe -l | grep kvm
modprob -r kvm_intel
modprob -r kvm
rm -rf /lib/modules/.../kernel/arch/x86/kvm (for all kernels)
(restart, still loading!)
sudo apt-get purge libvirt-bin
(restart, now gone!)
It still was crashing, so I uninstalled virtualbox and downloaded the latest version from their website. There was some sort of error with vboxnetflt during installation, but it claimed to have installed successfully. Still not working, so i ran:
sudo /etc/init.d/vboxdrv setup
Restarted, yet again, but it is still crashing!
