Thanks for reporting! Apparently this should use -netdev rather than -net

https://wiki.qemu.org/Documentation/Networking#The_legacy_-net_option

Also the -net nic is now -device, and the vlan=0 parameter needs hubport ...

Same issue is probably relevant for machine-drivers/docker-machine-driver-qemu

This was changed in qemu 3.0: https://www.qemu.org/2018/05/31/nic-parameter/

Still using QEMU emulator version 2.5.0 (Debian 1:2.5+dfsg-5ubuntu10.34)

Found out this is still not fixed in the most recent build.

@afbjorklund could we have a build that works with qemu 3.x, please?

[afbjorklund]

Do you have a patch ? Or maybe could help translate the syntax, can add the versioning

[afbjorklund]

Figured it out, eventually... Seems to work here ?

Thanks for trying podman-machine, hope that v0.15 works better for you.

Great update! Thanks @afbjorklund!

Just updated qemu on my macbook to 4.0.0 and I'm happy to report podman-machine works. :)
