Xen users - Feb 2010 - pv_ops domu memory limit ?

Hi,

is there a memory limit for Linux pv_ops domU ?

On my Dom0 (2.6.31.6-dae-dom0-00751-g60e0545 / Xen 3.4.2-2) I have a 
guest setup with 15600MB, when I start it, Linux (2.6.32.8) see only 8GB :

Feb 17 07:31:04 pacman kernel: [    0.000000] Built 1 zonelists in Zone 
order, mobility grouping on.  Total pages: 2066366

On Dom0, I have CONFIG_XEN_MAX_DOMAIN_MEMORY=32

If I do a "xm list", I see :
    Name                                        ID   Mem VCPUs      
State   Time(s)
    Domain-0                                     0   508     4     
r-----  15002.3
    pacman                                       6 15600     8     
r-----   6089.0

Do you know where can be the problem ?

Thanks,
Olivier

Well, I found this option in my kernel domu config file :
 > XEN_MAX_DOMAIN_MEMORY=8

Yes... I''m stupid ;)
