Re: [Xen-users] View DomU RAM Usage and Disk Usage from Dom0

["mitch@xxxxxxxxxxxx" <mitch@xxxxxxxxxxxx>]

The is stated from a position of relative ignorancve, but don't the pv drivers 
provide this to dom0 ? Things like xencenter rely on this information - so 
don't you need to just track down where the interface / query tool is?

        I have used xenstore-write and xenstore-read to do something like 
this. You would need to run a cron job on the domU to update the file(s). 
This could be security issue if you have un-trusted users connecting to 
the domU.

Cheers,

Tom.
