Re: [Xen-users] ssh from dom0 to domU
Well,
I think, from conversations we've been having on this list, that the
first thing to do is to try to disable checksum offloading on your
network cards (supposing that all the other bunch of stuff that can
go wrong, didn't).
An interesting thing to test is to check if you can connect from
a different *physical* machine on the same network into your guest
domains. If this works, it's an important data point.
You can do that with:
ethtool -K eth0 rx off
ethtool -K eth0 sx off
ethtool -K eth0 sg off
ethtool -K eth0 tso off
Good luck!
