Hi, I''ve set up a PV guest using xen 4.2 and kernel 2.6.32.57. the hypervior is 64bits whereas the dom0 and domu are 32bits. It seems to me that the memory allocation to domu is *limited to 3360M* when e820_host is enabled. I attached the domu configuration file and output of the command xl -vvv create and xl list. I am looking forward your reply. Thanks, HUAXIANG FAN Software Engineer II WEBSENSE NETWORK SECURITY TECHNOLOGY R&D (BEIJING) CO.

Hi Pasi, Thanks for your reply. I''ve tried the latest table kernel 3.6.3. The situation is better, but still not perfect. When I assign 6144M to domu wcg ,the output of ''xl list'' only indicates 5110M allocated for domu wcg. When I logon domu wcg, the totol memory is *limited within 3G*. I suspect the e820-map was wrong. I attached domu config file, output of command ''xl -vvv create domainWCG.cfg'', output of command ''xl list'' and output of command ''dmesg'' on domu wcg. Thanks in advance.

This would be in e820_sanitize in libxl_x86.c I guess ?
Konrad, are you looking into a fix ?
