Comment 316 for bug 1958019

What were your ./configure arguments?

Here were mine:
./configure --prefix=/opt/qemu/jcs --enable-kvm
--enable-trace-backends=log --target-list=x86_64-softmmu

Then I would run it with this script:
#!/bin/bash

_qemu=/opt/qemu/jcs/bin/qemu-system-x86_64

sudo $_qemu -enable-kvm -hda win10.qcow2 -m 8G -smp 4 -vga std \
-device vfio-pci,host=00:1f.3,multifunction=on,x-no-mmap=true \
-trace events=/path/to/events.txt

The contents of events.txt:
-vfio_region_read
vfio_region_write

I'm not sure if the events.txt is needed for JCS Qemu, but they don't
hurt. :)

Does it always hang? I did notice this version of qemu would often hang
during OS startup (less than 50% of the time though). Glad to know it
wasn't just me. :)
