Re: [Xen-users] Free XEN / DomU management software
Here is the info you requested.
For the record, I installed the xn-suite on a dom0, which currently does
not have any domU running. I thought it was possible already to use this
dom0 as a centralized monitoring system ... have to wait 2 months more ;-)

A few questions more.
1 - Can xn-suite monitor Xen domU's hosted in different dom0's? What
is it done?
Currently - no. But we are currently working on a xmlrpc and a
centraliced management interface.
I think it is (stable) done within <2 month.
2 - I did not saw it written anywhere, but I guess that the xn-client
should be installed in every dom0 hosting domU's, right?
The xn-client provides the mem- and performance-data to his dom0.
If you want to use the modules xn-mem and xn-mom, you have to install
the xn-client to each domU.
3 - I'm getting the following error:
*ERROR:* Can't comunicate with xn-manage-daemon! Check if the daemon

Looks like a problem with the IPC, can you run "ipcs -q" and send me
Or it is a bug with domU names who are longer then 32 chars or
including a dot. If it is so, update to the version 0.82.
