Hello, I am confused by a warning from mkswap : When making a swap on a LVM volume, I see the following warning : mkswap: /dev/vg_SDB1/swap_test6_64: warning: don't erase bootbits sectors on whole disk. Use -f to force. Setting up swapspace version 1, size = 1048572 KiB Is it safe to use mkswap -f in this case ? (If that matters, the swap is intended for a virtual machine, and the

Hi, I am getting following error on creating a swap fs.

hi, am starting to play with XEN - the virtualisation project (http://xen.sf.net). i''ll give some background first of all and then the question - at the bottom - will make sense [when posting to lkml i often get questions asked that are answered by the background material i also provide... *sigh*] each virtual machine requires (typically) its own physical ram (a chunk of the

All- I''m wondering if there is a guide or a general Getting Started for porting Xen to different architectures. I''m interested in supporting the arm platform. Any help or direction is greatly appreciated... Thanks! Carl - -- "There are 10 types of people in the world: Those who understand binary and those that don''t."

From sf.net/xen I have obtained xen2.0 and brought xen2.0 stable up on FC2. I am trying to find out a way to obtaining a tar file of xen2.0testing, without bk. I may have overlooked something here, helpful corrections solicited. Thanks in advance. -- Woody Marvel LTC Open Source Projects tel: 503-578-3833/775-3833 email: marvel@us.ibm.com

Changes in xen/arch/x86/domain.c in 2.0.2 break comiple for me with: ld --oformat elf32-i386 -T x86_32/xen.lds -N \ boot/x86_32.o /home/root/xen-2.0/xen/common/common.o /home/root/xen-2.0/xen/drivers/char/driver.o /home/root/xen-2.0/xen/drivers/acpi/driver.o /home/root/xen-2.0/xen/drivers/pci/driver.o /home/root/xen-2.0/xen/arch/x86/arch.o -o /home/root/xen-2.0/xen/xen-syms

Is there a way to discovery how much free memory I still have to use in a new domain? Another question is about cpu usage. I guess that xen scheduler allocate a fixed time slice for all virtual machines and does not make any idea if the virtual machine is using or not using all this time, right? How I can identify if CPU is the bottleneck? Thanks! -- Flávio Bruno Leitner

Hello there, I am looking around for days where I can dig some information on how to build Xen on FreeBSD... Does anybody here have any good doc / pointer on how to find it... BTW on xen-unstable there no FreeBSD tree... ? ;( where is it then ? Many thanks /Xavier -- Xavier Beaudouin - Unix System Administrator & Projects Leader.

I''m continuing to work on making a new XenCD as previously discussed here. In the course of that work, I''ve generated (actually, currently stuck on) the enclosed crash dump. Thought I''d forward it for interest. To head off questions, you''ll see references to a very large initrd (~114 Mb). The Xen dump may or not be related to this unusual usage.

Hello fellow xenophiles and happy new year! I''ve documented the install procedure for a prototype server here since I found no similar document Anywhere on the net. It''s a Sarge-based Domain0 on linux root raid from scratch, using LVM to store the data for the domU mail server and its mailstore. I humbly submit my notes in the hope that they are useful to some weary traveller.

The unstable tree now includes support for SMP guests, i.e. domains which run on multiple cpus. SMP guests can use between 1 and 32 virtual cpus, even if the machine has fewer physical cpus. The code is highly experimental and performance will improve over time. To use SMP guests: - enable option CONFIG_SMP in the Linux 2.6 kernel config - dom0 will boot with upto the number of physical cpus in

Hi! Coral isn''t working from Xen. If you can please try it, maybe i''m just doing something wrong. However it works from outside Xen with the same setup. Can Xen cause this kind of DNS errors? Try something like: http://www.scs.cs.nyu.edu.nyud.net:8090/coral/ or http://www.google.com.nyud.net:8090/ -- /Varga Péter/ ------------------------------------------------------- The

Hi, I was trying to run a guest OS with multiple partitions. I added a line like disk=[''phy:hda6,hda6,w''] in the configuration file. The disk was not mounted in the host OS. However, the kernel refuses to boot with an error message which says "kernel not syncing... attempted to kill init... rebooting...". When I remove that line, everything works. Is there

Why is figlet source included in xen? Wouldn''t it make more sense to alter xen/Makefile, to have compile.h built from a .in, and the figlet view of the version info, and have the upstream developers regen the figlet part when the version changes? I''m willing to modify the build system to do this. I''m also fixing several other poor implementation of things.
