[Bug 1862110] [NEW] qemu in script is not parsing properly

[Chris Hoy]

Public bug reported:

Bug Report: 
>>qemu-system-x86_64 --version: QEMU emulator version 4.2.0
>>Arch-linux version 2020.02.01
I was following a tutorial on how to make a windows vm and i have encountered 
and issue in the settings of my script I have listed below.

The commented code directly above the uncommented qemu instance would
boot the Windows screen but the issue arises when I try to reach the
same code block under the commented setting lines which takes me to the
default SeaBIOS loader.

 
#!/bin/bash

vmname="windows10vm"

if ps -ef | grep qemu-system-x86_64 | grep -q multifunction=on; then
echo "A passthrough VM is already running." &
exit 1

else

# use pulseaudio

export QEMU_AUDIO_DRV=pa
export QEMU_PA_SAMPLES=8192
export QEMU_AUDIO_TIMER_PERIOD=99
export QEMU_PA_SERVER=/run/user/1000/pulse/native

cp /usr/share/ovmf/x64/OVMF_VARS.fd /tmp/my_vars.fd
