After numerous attempts to get Xen up and running, I''m on the edge of giving up. I''m now running Xen-3.1 / Ubuntu-7.10 When trying to build a DomU I always crash. Tryied it with LVM and also the guide at: http://www.howtoforge.com/ubuntu-7.10-server-install-xen-from-ubuntu-repositories I changed memory-cards but still no results. Most of the crashes happen when doing a xen-create-image at debootstrap. My system: Supermicro PDSMI+, with Dual Intel P4 2 SATA -disk in software Raid-1 Has anyone made a succesful setup with this sort of hardware? Or is Xen-3.1 having problems with software raid? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I''ve found out that the problem is in the xen enabled kernel shipped with Ubuntu. I''ve submitted a bug report for it, but it still receives a few messages a month about similar problems. In my case the Dom0 crashed at any attempt read/write to/from the disc. Good Luck!

I solved the problem by turning Hypertreading off in the Bios. After that I bumped into other problems: (see also previous threads) - console, fixed by adding in the DomU-cfg extra = "xencons=tty console=tty" - hwclock: fixed by chmodding /sbin/hwclock to 400 (mount the disk-image with -o loop before you can do that) I have a domU running now, and doing some stress-tests right now (1h without problems) Gémes Géza schreef:> Pascal Nobus írta: >> After numerous attempts to get Xen up and running, I''m on the edge of >> giving up. >> >> I''m now running Xen-3.1 / Ubuntu-7.10 >> When trying to build a DomU I always crash.

I tried a lot to get Ubuntu 7.10 Xen setup working properly. It DOES NOT work reliably. I don''t recommend at all unless there are some updates. I switched to Fedora 8 as my Dom0 OS. This has other problems though (the famous virbr0 virt-lib stuff etc.) Emre On Dec 4, 2007 9:44 PM, Gémes Géza <geza@kzsdabas.sulinet.hu> wrote:> Pascal Nobus írta: > > After numerous attempts to get Xen up and running, I''m on the edge of > > giving up. > > > > I''m now running Xen-3.1 / Ubuntu-7.10 > > When trying to build a DomU I always crash.

(my machine can take several hours to build image.... no doubt a bug, but not a "crash".) 2) When starting the domU, mine took 6 hours to start up fully. (hwclock eating up all domU CPU time.) 3) Here is some advice I got from others on the list, but have not been able to get to the machine to try yet: ~~~ 1. add the line: extra=''xencons=tty'' (in DomU config file) 2. modify the domU''s /etc/init.d/hwclockfirst.sh and /etc/init.d/hwclock.sh by either disabling them in a ugly way by: chmod 000 /etc/init.d/hwclock* or by disabling them nicer via adding exit 0 to the 3rd or 4th line at the beginning of the scripts 2b. alternatively, set the independend_wallclock in /proc/... (sorry for that, i missed the exact path, and don''t have a system handy) ~~~ Let us know if it helps... ____________________________________________________________________________________ Get easy, one-click access to your favorites.
