[Xen-users] Xen 3.0.2.2 - Losing network after starting xend.
Hi list.
I am trying to upgrade a well-running server from Xen 2.0.6 to 3.0.2.2.
After building and installing 3.0.2.2 from source the machine boots OK
in 3.0.2.2 and dom0 comes up and I ssh into it. But after starting xend
I loose the network. Going to the physical console I did an
''ifconfig''
and had the response below.
What''s wrong here ? Is Xen trying to change my network card to run
IPV6,
or has it just renamed eth1 (which is the physical network connection)
to veth1 and use IPV6 internally for the bridging ? How can I get
network connectivity back ?
Cheers
