I am trying to enable the default libvirt network to be able to create a vm. However when i try to start the default network, this occurs:

sudo virsh -c qemu:///system net-start default error: Failed to start network default error: Unable to set bridge virbr0 forward_delay: Operation not permitted

with net-list --all you can see that it is not running: sudo virsh -c qemu:///system net-list --all

Name State Autostart Persistent

----------------------------------------------------------

default inactive yes yes

is there another way to start the network. I am not needing to see other devices on the network, just need internet access.

is the problem because it doesn't exist? If I do ip addr show it doesn't come up

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default link/void inet 127.0.0.1/32 scope host venet0 valid_lft forever preferred_lft forever inet 206.---.166.---/32 brd 206.---.---.96 scope global venet0:0 valid_lft forever preferred_lft forever inet6 ::2/128 scope global valid_lft forever preferred_lft forever

  • Hi, am I assuming correctly that you are running inside a container, because there I have seen this in bug 1802906 and bug 1784501 before. You either need to upgrade to Ubuntu 19.04 or later to get the fixes or make your containers slightly more privileged as outlines here – Christian Ehrhardt Jul 5 at 9:15
  • @ChristianEhrhardt This is a VM running in OpenVZ. I guess I will have to wait until they release a later iso. Thanks for your reply – Lindsay Sperring Jul 5 at 9:20
