Re: [Xen-devel] Hard lock of server - saved history from serial consolewithin

[Matt Ayres <matta@xxxxxxxxxxxx>]

Routed / Proxy ARP.

vif-route assigns an IP to the appropriate vif interface.  The IP's of 
the VM are routed through the vif interface.
It's really nothing special... routing is actually less complex than 
bridging IMHO.
Is this perhaps a 2.6.16 kernel bug?  Are there any dis-advantages to 
upgrading to 2.6.16.9 or .10-rc?
Thanks,
Matt
