ipv6 NAT; accept_ra errors and about network choice
Hello,
Firstly THANK YOU for the IPv6 NAT support merged in 6.5. It has been
almost impossible to get IPv6 into a VM on a laptop that switches
between wifi and wired (dock) connections, because you can not add a
wifi interface to a bridge. I know NAT is against the IPv6 end-to-end
xen but it makes this "just work" for the vast majority of people like
me who need to ssh/curl/talk to

When you add a default gateway with:
route add default gw 192.168.1.1 dev enp3s0
you'll note that you now have 2 routes with the same metric of 0 (use
route -n to see the metric field - couldn't get ip route to show me the
metric).

No eth0 device found in domU
Hi,
I tried already a long time to enable network in my domU but I always
fail with:
# ifconfig eth0 192.168.0.1 up
SIOCSIFADDR: No such device
SIOCGIFFLAGS: No such device
Do I need to load a kernel module?
I use OpenSuse 10.2 with kernel 2.6.18.8-0.5-xen (for both domU and dom0).
My config:
kernel = "/boot/vmlinuz-xen"
ramdisk = "/home/jens/initrd.gz"

I cannot get any windows client to successfully join the domain. Each
