No network inside Linux guest

[horacelau]

Host is MacOS 10.14.6.

I've tried TinyCoreLinux and Ubuntu (16.04.6-server-amd64). Guest unable to get DHCP response. Tried manually configuring network with IP in 192.168.64.x subnet (i.e., 192.168.64.5) but unable to ping host and host also unable to ping guest.

Tried both virtio-net and e1000.

Using brew xhyve (HEAD-1f46a3d).

Here's ifconfig with Linux guest booted:

[horacelau]

No one has any ideas on how to debug this issue?

@horacelau I figured this out:

1. You need to run it with sudo.
2. You need to add -s 2,virtio-net,tap0 into the executable.

Thanks @xpepermint, but that doesn't seem to fix my problem.

@horacelau FWIW I had to install my guest with the -U ... option before it could see out

Can you provide details on exactly what you did?

[dijitaltrix]

@horacelau Create a UUID (from a Mac shell prompt use uuid), copy that into your vm startup script, then run the VM and install the guest OS. You'll need to run it with sudo, I've added an example run script (for FreeBSD) here https://gist.github.com/dijitaltrix/2986ec7953600217933e5af504a09352
