Interfaces to look at: enp0s25, enp0s25 Just to help me confirm my intuition: do you have several RA routes defined for the same device? > # echo 2 > /proc/sys/net/ipv6/conf/enp0s25/accept_ra > > # virsh net-start default > Network default started > > try create: > > # virsh net-create default.xml > error: Failed to create network from default.xml > error: 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: enp0s25, enp0s25 This one sounds weird: if the accept_ra is set to 2 as you report you did, you shouldn't get that error. -- Cedric > On Wed, Mar 15, 2017 at 10:45 PM, Cédric Bosdonnat <cbosdonnat@xxxxxxxx> wrote: > > Hi Laine, all, > > > > Here is the v2 of my series.
