How can I change from network of 10.0.0.2 to 192.168.88.2

[realChytraeus]

Expected behaviour

I have a netbsd-9.2 virtual machine I added with quickgui. In the netbsd-9.2/ folder I added the following to netbsd-9.2.sh after -netdev.
192.168.88.1/24. This changed nothing so I removed 192.168.88.1/24.
I tried and tested adding the option of -netdev to netbsd-9.2.conf . I added the following line to it:
-netdev="192.168.88.1/24"

Actual behaviour

I restarted the VM and using ifconfig I see that I still have 10.0.2.15.
I would like to be able to have all Linux and BSD VM's and other OS's on my local network of 192.168.88.2.

Steps to reproduce the behaviour

see above.

To pass extra arguments to qemu you need to add --extra-args to your config file or command line.
You'll also probably need to quote arguments especially where things like "/" appear (see your error message above). You need to look at the qemu manual to craft the --netdev you need to pass, but it looks to me that you at least need something like:

--extra-args='-netdev user,id=mynetid,net=192.168.88.1/24, ...

based on the -netdev entry in the /.sh that quickemu generates. You can tweak and re-run that generated bash script until you get the incantation right but remember quickemu will regenerate it so you need to adapt your config file.
