Subject: Memory oversubscription
Date: Tue, 14 Sep 2004 17:39:19 -0500	[thread overview]
Message-ID: <41477317.4080004@cs.wisc.edu> (raw)

Hi.  First of all, thanks for Xen.  It's terrific!

I'm interested in doing memory oversubscription and am wondering if Xen 
can do this (now or in the future). 

For example, on a machine with 100MB available physical memory, can I:
1. Create a domain with a 90MB allocation
2. Inflate a balloon in that domain and return say 40MB back to Xen

I know there are mechanisms for doing 1 and 2...

3. Allocate a second domain with an allocation of 50MB?

Thanks,

--Todd
