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 total used free shared buffers cached Mem: 2869 1068 1800 0 25 65 -/+ buffers/cache: 977 1892 Swap: 1027 0 1027 root@xmao# xm li Name ID Mem VCPUs State Time(s) Domain-0 0 4862 4 r----- 1272.6 root@xmao # xenstore-read /local/domain/0/memory/target 4979676 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 Mem: 4860 1550 3309 0 14 75 -/+ buffers/cache: 1460 3399 Swap: 1027 0 1027 Where is my memory going with 32.36?
