To add, it was pretty clear the VM never came up just by looking at top/htop. qemu-kvm was
using negligible (0.7% of a core) CPU. I'm 99% certain this is the cause of my woes.
Using Q35 with UEFI should be fine, as most systems are fine booting from UEFI. However,
I'd like to have the option to use the BIOS version in case it is needed for some
reason.
I'd also like to know how I can override the default chipset type when using
hosted-engine --deploy, if at all possible, to work around this.
