Thanks for reporting this bug. I suspect this is actually a libvirt bug. To make sure, could you check whether
kvm -spice addr=127.0.0.1,port=5900 works for you? At least in an empty network namespace on my host this seemed to work fine. ** Changed in: qemu (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1492621 Title: Cannot start VMs without routable IPv4 address To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1492621/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
