RTNETLINK answers: File exists
ifup: failed to bring up eth0
Xen shutdown then boot
# cat /run/network/ifstate
lo=lo
eth0=eth0
I just rewrote the interfaces file. Well copied and pasted from other VPS
then changed the relevant addresses. Then did Xen shutdown and booted it
again, to ensure config files were re read.
Discovered that in a previous edition I had left out the auto eth0 line so
obviously ifupdown was not reading it. ipv4 was obviously coming from
hobgoblin somehow
Sorry, and thanks
