Re: [Xen-devel] keep console attached during reboot?

Glad to see upgrades are still happening :-) Had you been using 2.0.4, or had
you just not used Xen for ages? It seems some people have been getting > 1
year uptimes out of Xen, which is nice to know about.

Yes, I miss it too - I'd had a feeling we used to support this but couldn't
remember when. Currently I don't think there's not a way to get back to the
old behaviour.

I suspect that modifying tools/console/client/main.c to reconnect if possible
when a connection drops would be the easiest way to hack this in.
The strictly proper way IMO would be to modify tools/console/daemon/ to only
close the connection if a VM has shutdown / been destroyed, otherwise
establish a console ring with the new domain and continue using the same
connection. I might have a look at this if nobody else gets to it first...
Cheers,
