[opensuse] How to network with a VM?
Hi, I'm running GNOME on openSUSE 13.2 with all updates. Using yast, I have set up a KVM hypervisor, and installed opensuse 13.2 in a VM. Using virt-manager I can run the VM and interact with its GUI. I can open a browser in the guest and surf the net. So far so good. Now I want to SSH into the VM, and I can't figure out how to do it. sshd is running in the guest, its firewall is disabled, and its IP-address is 10.0.2.15. Yet, trying to ssh to connect to that address doesn't work. What do I need to do to be able to contact a server process in the VM from the host?

First suspect is routing on host machine, check with "ip route", is there a routing entry for your VM, or is there only the standard routing from the host machine? Second suspect is the firewall on the host machine. does a ping from host to your VM work? (Best would be posting the output of the "ip route" command) - Yamaban -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

# ip route default via 10.0.1.1 dev wlp2s0 proto static metric 1024 10.0.1.0/24 dev wlp2s0 proto kernel scope link src 10.0.1.22 Seems to be a missing route, as you suggested. Do you happen to know the command to add a route between host 10.0.1.22 and guest 10.0.2.15 ?

Even with both the host and guest firewall disabled, I'm unable to ping in either direction. Olav -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

10.0.2.15 is default address when using user mode networking in QEMU. In this case guest network is completely emulated inside qemu process. You can tell qemu to forward ports from host into guest; see e.g. https://en.wikibooks.org/wiki/QEMU/Networking#User_mode_networking I do not use virt-manager, so I do not know how to configure it there. Advantage of user mode is that it does not require superuser rights on host to configure (no interfaces to set up etc). -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
