[libvirt] [PATCH v2 0/5] Prevent losing IPv6 routes due to forwarding

[Yalan Zhang]

Hi Cédric,

I have tested it, it works well. But the interface name will repeat 2
times.
Please help to confirm this, and if below test for a single port host is
enough?

# cat /proc/sys/net/ipv6/conf/enp0s25/accept_ra
1

enable network default with ipv6 ip section

# virsh net-start default
error: Failed to start network default
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

# 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
