You can add a data drive to this commandline with this option -drive file=/dev/sdc,format=raw,if=virtio It applies accelerated graphics and audio. The command will boot a uefi enabled USB drive with my copy of rEFInd. The new command is safer and there are no warnings or errors. A couple days after finding the solution I discovered another problem with my handling of the format of the disk. Sometimes it works sometimes it doesn't but with the cp command it works fairly consistantly. In the command at the beginning is a fix for pulse audio. I don't think I can explain all the details on how this works but I'll leave my solution here for others. Sudo qemu-system-x86_64 -machine accel=kvm:tcg -m 4096 -bios /usr/share/ovmf/OVMF.fd -audiodev pa,id=pa,server=unix:$/pulse/native,out.stream-name=foobar,in.stream-name=foobar -device intel-hda -device hda-duplex,audiodev=pa,mixer=off -rtc base=localtime,clock=host -smp 16 -vga virtio -display gtk,gl=on -drive file=$BOOT_USB,format=raw,index=0,media=disk Sudo cp ~/.config/pulse/cookie /root/.config/pulse/cookie N0rbert's utility didn't do exactly what I wanted however by inspecting the sourcecode I was able to make my commandline work like this: BOOT_USB="/dev/sdb" Family 17h (Models 00h-0fh) HD Audio Controller According to lspci my soundcard is this:Ġ9:00.3 Audio device: Advanced Micro Devices, Inc. Any help or advice would be greatly appreciated. I seem to have a fundamental problem understanding how sound is routed through qemu and the host computer speakers. However the sound panel still says dummy output and no sound comes out of the host speakers. No special sound errors were thrown by this. So I modified my command line like this per the instructions:īOOT_USB="/dev/sdf" sudo qemu-system-x86_64 -soundhw sb16 -machine accel=kvm:tcg -m 4096 -bios /usr/share/ovmf/OVMF.fd -smp 16 -vga virtio -display gtk,gl=on -hda $BOOT_USB I tried this commandĪnd one of the options is sb16 which a friend recommended as something which worked for him. I wish to both hear the vm and record it with obs in the rest Only one thing missing that I need and that is sound. Video is fast and smooth, processing speed is acceptable. This qemu command allows me to boot to my usb drive and gives me great speedīOOT_USB="/dev/sdf" sudo qemu-system-x86_64 -machine accel=kvm:tcg -m 4096 -bios /usr/share/ovmf/OVMF.fd -smp 16 -vga virtio -display gtk,gl=on -hda $BOOT_USB I want to screen record the setup process and other tasks to show it off. For the purpose of this question both the host and the guest are the same system in layout, they are both based on Ubuntu-Mate. I wish to use QEMU for screen recording the whole setup and usage phases of the system. I am developing a plosia (persistent libre operating system for industrial applications) that is self contained on a high speed usb micro thumb drive.
