unable to configure port forwarding for :443

[orzechowskid]

Expected behaviour

• VM successfully boots
• accessing https://localhost from inside the guest OS should connect to :443 on the host

Actual behaviour

VM fails to boot and exits with code 1

Steps to reproduce the behaviour

1. install quickemu on host
2. install OSX Monterey as guest
3. edit macos-monterey.conf and add the following line to enable port forwarding of :443 : port_forwards=("443:443")

I should note that the guest OS boots just fine when using the example from the quickemu documentation: port_forwards=("8123:8123" "8888:80")

and another unprivileged port also seems to work fine: port_forwards=("3000:3000")

I'm getting the same. The error here seems to be that the quickemu command will fail if the host port is occupied (not exclusive to 443)

I've tried to do port_forwards=("8080:8080") so that I can access my localhost:8080 web server from the guest machine.

However, if localhost:8080 is occupied by the web server, quickemu --vm ./macos-ventura.conf will fail. If the port is free, quickemu will run normally.

I'm wondering if it is possible to access an occupied port from the host machine from guest.

Quickemu runs in the user context, therefore, an unprivileged user account. Unpriviledged accounts are not able to bind to ports <= 1024.

You should bind a port > 1024 on the host to 443 on the guest:

port_forwards=("8443:443")

I am having the same issue. Did you find a solution?
