make communicate two guests on the same network

[bertuz]

Hi, I'm unsuccessfully trying to make two/multiple guests defined within my vagrantfile to communicate among each other. Is it possible? As far as I see netwroking is still in progress and a user type is sent by default. I'm wondering if I could use another solution to create a unique virtual network the guests share

Currently, this plugin uses "user mode networking" for simplicity. I think there still be able to connect multiple guests together:

• Use forward port: vm A forwards 80 to host:8080, vm B connects to host:8080 (for example, 10.0.2.2:8080)
• Use "Socket" networking to connect guests' network, see https://wiki.qemu.org/Documentation/Networking#Advanced_user_networking_options and https://lists.gnu.org/archive/html/qemu-discuss/2014-11/msg00020.html for details
• Use manual created bridge, and bridge config for qemu, see https://futurewei-cloud.github.io/ARM-Datacenter/qemu/network-aarch64-qemu-guests/ as a example (just found by google)

The latter two methods require the use of extra_qemu_args to set up the new network config.

I haven't tested them (except the first one, I connected to ssh port of another vm), feel free to report any problems.

done it! Thanks for your support. the extra_qemu_args does help. I'm using Mac OS' Hypervisor with its own networking system.

vb.extra_qemu_args = "-M accel=hvf -netdev user,id=mynet0,net=192.168.76.0/24,dhcpstart=192.168.76.9 -netdev vmnet-shared,id=mynet1 -device virtio-net-pci,netdev=mynet1,mac=54:54:00:55:55:5#{i}".split
