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...

...allooning is called 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.

Hello there, We (a small hosting community) are running a steadily growing number of Xen domUs on a quad dualcore Xeon server with 64GB ram. We''ve got 100 running domUs at the moment.

Where is the code that maps the kernel of a DomU into memory? i.e, when you do a xm create <config file> what code is called to actually map the kernel into memory? Is it a python script or is it re-directed to Dom0 to do? Thanks. -Brian --------------------------------- Ahhh...imagining that irresistible "new car" smell? Check outnew cars at Yahoo! Autos.

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -

Linux 3.11 added respective support, so I think we should follow suit. 1: xen: add LZ4 decompression support 2: libxc: add LZ4 decompression support Signed-off-by: Jan Beulich <jbeulich@suse.com>
