Reverse Network Interface Assignment

[ramukima]

Following the example at https://hub.docker.com/r/bbvainnotech/kvm/ when I connect my container to more than one networks, the network assignment inside the container is random. What I expect as eth0 becomes eth1 and vice-versa.

QEMU literally takes the first interface as one that is passed first on the command line, the networking of my VM is revered from what I expect.

What would be an idea way to fix this ? Is just "sorting" based on interface number sufficient ?

The following should take care of network assignment in the order they are specified..
