Hello everyone... I get the following error when i try to creat a virtual machine Error: (4, ''Out of memory'', "xc_dom_boot_mem_init: can''t allocate low memory for domain\n") I''m using Xen under Gentoo, kernel 2.6.32-r1 in a i686 Dual Core AMD Opteron(tm) Processor 290 AuthenticAMD with 16Gb of memory and 4Tb of hard disk. It was a pain to install xen in it but when i finally did it, i get this error whe...

...to extract memory from dom0. During the ballooning a loop in libxl_wait_for_free_memory() waits unless enough memory is available to create the domU. But because of a variable-underflow the loop can finish too soon and xl finally aborts with the message: xc: error: panic: xc_dom_boot.c:161: xc_dom_boot_mem_init: can''t allocate low memory for domain: Out of memory libxl: error: libxl_dom.c:430:libxl__build_pv: xc_dom_boot_mem_init failed: Device or resource busy libxl: error: libxl_create.c:901:domcreate_rebuild_done: cannot (re-)build...

...from the ballooning and reservation support added a few years ago: http://lists.xen.org/archives/html/xen-devel/2009-11/msg01277.html 32 bit domains eventually fail to boot with the following Xen complaint: xm create: Error: (4, ''Out of memory'', "panic: xc_dom_boot.c:159: xc_dom_boot_mem_init: can''t allocate low memory for domain") Booting with dom0_mem=128G, with enable-dom0-ballooning=yes and total_available_memory=128 set in xend''s configuration works as expected. 128GB of RAM is avalable 32bit guests and 128GB for 64 bit guests. I''m able to account...

Hi, I was wondering if there is any documentation on how to write a bare metal application for Xen. I don''t need to parse the device tree and such yet, a simple booting "Hello World" would be fine :-) We wrote one and when trying to boot we get ( this was an uncompressed binary, no image): libxl: notice: libxl_numa.c:451:libxl__get_numa_candidate: NUMA placement failed,
