I'm using xen-unstable from 28th March, running on top of a Centos 4.3 system.
All seems to work well except for one strange networking error.

In my DomUs, all of my networking works except for sftp.

I can wget http://www.google.com and get an HTML page back. I can ping, and I can ssh to any host I like. But if I try and sftp to any host, I get an error:

socketpair: Address family not supported by protocol

This seems strange to me because I thought sftp was using the same protocols as ssh, so I can't see why one works and one doesn't. There's nothing in the logs. The only clue I get is sometimes when booting the DomU I get the same" Address family not supported by protocol" error when the interfaces are being brought up.

Any pointers as to where to look appreciated,

You could run an strace to see what syscall is made when it complains. Could point to a missing kernel interface.
