Hi:
 
    Recently I am trying pvops dom0 kernel, 2.6.32.36, but confronted some strange things.
 
    In my grub, i give dom0 5630M memory. But when system startup, use free -m, only see 2869M in total.
 
title Red Hat Enterprise Linux Server (2.6.32.36xen)
        root (hd0,0)
        kernel /xen-4.0.1.gz msi=1 iommu=off x2apic=off console=com1,vga com1=115200,8n1 noreboot dom0_mem=5630M dom0_max_vcpus=4 dom0_vcpus_pin cpuidle=    0 cpufreq=none no-xsave
        module /vmlinuz-2.6.32.36xen ro root=LABEL=/ hda=noprobe console=hvc0
        module /initrd-2.6.32.36xen.img
 
 
Free -m output
 
root@xmao # free -m

and dom0 auto balloon is disabled in /etc/xen/xend-config.
 
Well, when I use 2.6.32.10. Everything is OK
Free output in 2.6.32.10
root@xmao # free -m
             total       used       free     shared     buffers     cached

Swap:         1027          0       1027
 
Where is my memory going with 32.36?
 
Thanks.
