Thanks.
I will look into this.

Public bug reported:
Hello,
I have a nice working qemu with gpu passthrough setup.
I pass through my nvidia gtx 880m.
It boots in 4mins 18secs.
If I remove the "-vga none" switch and allow qemu to create a vga
adapter I can boot in 1min.
Why does a normal boot with the nvidia card hang for 3mins
I meant to say you cannot run without the intel card in windows if you
have optimus. I am glad seabios somehow hides optimus.

It works using seabios. I assume that the nvidia driver cannot see
optimus, and expect an intel card also, unless I use OVMF. I do know
that you cannot run off the intel card in windows. It's a no-no. Thanks
for the bios tip. Maybe I can hide the optimus feature from OVMF and
windows.

ok, so I will research qemu and nvidia optimus. I have a custom BIOS
made by an MSI employee. I have hundreds of bios options to play with.

I have been told that getting this to work with a laptop is rare.
I own an MSI GT70-2PE.

Only a full reboot of linux fixes this issue.
Qemu appears to corrupt something in linux when exiting.
