[Xen-devel] Possible regression: XEN 4.0.0 total_memory decrease

[Alex Williams <awilliams@xxxxxxxx>]

Hello,

I noticed a significant *decrease* (150MB) in "total_memory" on a host 
build using XEN 4.0.0 with kernel 2.6.18.
Here are the details:

Server = 4096MB RAM
XEN 3.4.2 + kernel 2.6.18: xm info | grep total_memory = 4084
XEN 4.0.0 + kernel 2.6.18: xm info | grep total_memory = 3946

The exact same kernel config file was used for both builds. I also made 
sure there is absolutely no difference on the hosts (while the builds 
are created on a different machine).
This seems like a regression, unless someone can provide suggestions on 
how to correct this?
Thanks.
