Title:
slow boot windows 7
Status in QEMU:
Expired
Bug description:
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 (yes, the
hd light just flickers for that long)?
Nothing major but I'd like to know, especially if it can be fixed.
I cannot leave -vga none turned on as the vga adapter grabs up
resources and the nvidia card complains it cannot start due to lack of
resources. I'd love to just add resources if possible and keep both
cards running to get the 1min boot time.
Here is my script:
qemu-system-x86_64 -machine type=q35,accel=kvm -cpu host,kvm=off \
-smp 8,sockets=1,cores=4,threads=2 \
