Re: Xen-Fedora4 or 5, dead-end...

Hi big friend "Steven Anderson",

"Try changing the MTU size to 1492 or 1460 on the interfaces except"

Its suggestion for the problem of the FC4 functioned yes Sir. Now I am
calmer and with this already I can place the server in production with
bigger tranquillity. However I notice some other instability in xen of
the FC4, therefore it wanted to exactly see xen of the FC5 to function,
therefore if something to give wrong already would have the solution...

Much thankful by the attention.

Greetings,
