Port forwarding to host OS does not work with podman machine

[mmalina]

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description

Exposing of container ports is not propagated to host OS when using podman machine on macOS.
According to the release notes it should work now:

Containers inside VMs created by podman machine will now automatically handle port forwarding - containers in podman machine VMs that publish ports via --publish or --publish-all will have these ports not just forwarded on the VM, but also on the host system.

Steps to reproduce the issue:

1. podman machine init

2. podman machine start

3. podman run -p 8080:80 docker.io/library/nginx

4. curl http://localhost:8080

Describe the results you received:

curl: (7) Failed to connect to localhost port 8080: Connection refused

Describe the results you expected:

Nginx welcome page should be returned. (It works if I run curl inside the VM - using podman machine ssh)

Additional information you deem important (e.g. issue happens only occasionally):

Another issue is that if I stop the container and start a new one, I get:

Error: rootlessport listen tcp 0.0.0.0:8080: bind: address already in use

Let me know if I should create a new issue for this.

Note that I get this warming when starting the VM using podman machine start, but it doesn't seem significant:

qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000001H:ECX.svm [bit 2]
