Which network interface or IP address in the guest OS corresponds to which in the host OS?












2















I heard that a guest OS and a host OS in KVM can communicate via having network interfaces or IP addresses in the same private network. I also heard that




You can see its IP addresses and network interfaces in the container
and VM networks in ifconfig’s output.




I show the outputs of ifconfig in a guest OS and a host OS below. Could you tell me which network interface or IP address in the guest OS corresponds to which in the host OS, and vice versa? Thanks.

  • Are you doing nat rules? How the ip will correspond to the guest?

  • I guess I'm missing the point of your question. This appears to be very basic networking, on the surface. Debian guest, ens3 is assigned 192.168.122.202. Lubuntu host, virbr0 is assigned 192.168.122.1. If you check the ip route and related settings on Debian, you will see the gateway address for Debian is 192.168.122.1. This is normal and more-or-less default behavior for libvirt/KVM/QEMU on Debian and Enterprise Linux based distros, in my experience.

  • Are you doing nat rules? How the ip will correspond to the guest?

    – Luciano Andress Martini
    yesterday











  • I guess I'm missing the point of your question. This appears to be very basic networking, on the surface. Debian guest, ens3 is assigned 192.168.122.202. Lubuntu host, virbr0 is assigned 192.168.122.1. If you check the ip route and related settings on Debian, you will see the gateway address for Debian is 192.168.122.1.

I guess I'm missing the point of your question. This appears to be very basic networking, on the surface. Debian guest, ens3 is assigned 192.168.122.202. Lubuntu host, virbr0 is assigned 192.168.122.1. If you check the ip route and related settings on Debian, you will see the gateway address for Debian is 192.168.122.1. This is normal and more-or-less default behavior for libvirt/KVM/QEMU on Debian and Enterprise Linux based distros, in my experience.

I would try the basic command line utility to check the network settings... ip route From the fine man page: linux.die.net/man/8/ip

Your guest has one non-loopback interface, ens3; that’s the interface it uses to communicate with the host. On the host, the matching interface is the interface in the same network, which is virbr0 here. If you want to list the interfaces which are part of the bridge, run



brctl run virbr0


on the host.



You can also match the routes in the guest to the host: the guest’s gateway will be the host. To see the routes, run



ip route list


The default gateway is given on the “default” line, something like



default via 192.168.122.1 dev ens3 proto static metric 100
