QEMU/KVM Libvirt forwarding

2

1

I am using OpenSUSE Leap 42.2 on a Dell Inspiron 1545. There was an error on default virtual network on KVM:

Error starting network 'default': internal error: Check the host setup: enabling IPv6 forwarding with RA routes without accept_ra set to 2 is likely to cause routes loss. Interfaces to look at: eth0, wlan0

Google found no results to that error.

  • Am I the only one who has that problem?

  • How do I set accept_ra to 2?

  • Any solutions to this problem?

Edit /etc/sysctl.conf or place your own any.conf file to /etc/sysctl.d/ folder with lines:

net.ipv6.conf.eth0.accept_ra = 2
net.ipv6.conf.wlan0.accept_ra = 2

After reboot this error will gone.

1It didn't work after a reboot. I had to run this as root (optionnally replace eth0 with your interface name): sysctl -w net.ipv6.conf.eth0.accept_ra=2 – knarf – 2019-07-18T12:55:49.243
