Hello

I wanted to understand if there is a way to get LXC container's ip address.

- virDomainInterfaceAddresses API only works for qemu/kvm and not with the lxc driver.

What other options do I have?

If you're not looking for a libvirt-only solution, you can just use `nsenter`: nsenter -t <pid-inside-container> -n ifconfig

virsh -c lxc:/// lxc-enter-namespace <domain> --noseclabel /sbin/ifconfig libvirt: error : Expected at least one file descriptor

For what it's worth, I was able to do the above without a problem with Fedora 23, running an alpine linux container (just unpacked the alpine docker image): sudo virsh -c lxc:/// lxc-enter-namespace alpine -- /sbin/ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:16:3E:10:25:32 inet addr:192.168.124.4 Bcast:192.168.124.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:46 errors:0 dropped:0 overruns:0 frame:0 TX packets:9 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4034 (3.9 KiB) TX bytes:2022 (1.9 KiB) I started the domain like this: virt-install --connect lxc:/// --name alpine -r 512 \ --filesystem /containers/alpine/,/ \ -w network=default When trying the same thing with a minimal Fedora domain, the above failed because the Fedora filesystem I started with contained neither `ip` or `ifconfig`...but worked fine once I installed the necessary packages. -- Lars Kellogg-Stedman <lars@redhat.com> | larsks @ {freenode,twitter,github} Cloud Engineering / OpenStack | http://blog.oddbit.com/
