I guess you should learn the Transcendent Memory (http://oss.oracle.com/projects/tmem/) from Oracle...

Am I right?

Hello,

I am running a functional Xen 4.0 platform. The objective is the project I am currently running is to replace 4 VMWare ESX by 4 Xen 4.0 hypervisors. I have been able to reproduce all the core VMWare features in Xen (but better of course =D) except memory overcommitment.

I know this feature has been included since Xen 3.3 but I have found almost no information about it.

When I try to start a domain with more RAM then is available on the server I get the following message :

VmError: I need 1433600 KiB, but dom0_min_mem is 200704 and shrinking to 200704 KiB would leave only 1348320 KiB free.

Well I know it doesn't have enough RAM, that's the whole point. Do I need to enable something specific somewhere ? I am using the Jeremy's 2.6.31 kernel (thank you whoever you may be !).

Thank you in advance for your help,

Antoine
