Re: Windows 10 or 11 as guest on Netbsd/amd64 with nvmm + sound?

[Brian Buhrow <buhrow%nfbcal.org@localhost>]

	hello.  Following up on this thread, I've made some progress toward this goal.
The following steps and included startup script, based on Chavdar's samples, will get you a vm
capable of generating good quality audio from the guest VM on the host machine.

1.  Build a NetBSD kernel for the host machine with HZ=1000 to increase the granularity of
qemu's clocks.


2.  Use the following qemu-startup.sh script, modified to taste, to start your guest OS.

3.  The aaudio will come through the default sound device on the host machine.


Hope this is helpful for someone.

-thanks
