Hi There . As from what I see, my system is not seeing all the available ( 4GB ) o memory, does xen take some for it''s own? Am I missing something in the kernel? netwarrior build-linux-2.6-pvops_x86_64 # dmesg |grep -i memo released 151863 pages of unused memory initial memory mapped : 0 - 20000000 init_memory_mapping: 0000000000000000-00000000aff90000 Memory: 2749108k/2883136k available (4930k kernel code, 392k absent, 133136k reserved, 2304k data, 512k init) Non-volatile memory driver v1.3 Freeing unused kernel memory: 512k freed EDAC amd64: This node reports that Memory ECC is currently disabled, set F3x44[22] (0000:00:18.3).

The kernel was compiled with big-mem support?

AFAIK xen themself reserve a very little memory (about 1 Mb or so). Main ''memory eating'' is xenballoon. I still don''t know where those memory use, but if you ran VM with high ''maxmem'' with low mem be ready to have huge overhead (20Gb maxmem have overhead about 300-400MiB).
