If VT-x is disabled, the virtual machine will be sluggish, so if it works, it'll be a bad experience. Don't do that. On Thu, Nov 8, 2018 at 11:04 AM Juliusz Chroboczek wrote: > > > When discussing virtual machines it would be helpful to mention which > > virtual > > machine hypervisor is being

Why are they creating 32-bit virtual machines? At least with virtualbox 32-bit VMs can run on any host. 64-bit VMs require VT-x which is all too often disabled in the BIOS.
