I'm also seeing this with several guest machines that I moved to a different host. I change the networking config and then this started to occur. I removed two NICs and added a new one. It currently has only one NIC. This was needed for virt-manager to associate the guest with the proper network on the host. After getting the message I modified /etc/networking/interfaces and /etc/udev/rules.d/70-persistent-net.rules to get my NIC working as expected, but the errors still show up.
'/etc/init.d/networking restart' works 'service networking restart' does not work. It simply fails with the "Unknown instance:" message. If I run 'initctl list | grep network' I see only the current interfaces, but I see a line that says "networking stop/waiting" so I think this confirms Watte's assumption that those results were a symptom, not cause. ** Changed in: sysvinit (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/440179 Title: service fails to start/stop/restart networking daemon -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
