Package: xen-hypervisor-3.0.3-1-amd64 Version: 3.0.3-0-2 Severity: grave Justification: renders package unusable This bug looks to be tracked in upstream: http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=762 Mailing list discussion here: http://lists.xensource.com/archives/html/xen-bugs/2006-11/msg00030.html -- System Information: Debian Release: 4.0 APT prefers testing APT policy:

Hi, you have to limit dom0 memory on two places, xen hypervisor option and xend config. In this example below I limit memory to 256MB: /boot/grub/menu.lst 87c87 < # xenhopt= --- > # xenhopt=dom0_mem=256M /etc/xen/xend-config.sxp 120c120 < (dom0-min-mem 196) --- > (dom0-min-mem 256) After changing /boot/grub/menu.lst you have to run update-grub and reboot the machine. After

I inherited a xen server that is setup to have all the VM images hosted on an iSCSI mounted NAS array. We been experiencing a random (about every 2-3 days) issue where xen would crash all the VMs, leaving nothing but the Domain0 running. What appears to be happening is something causes the iSCI mount to hiccup. Running "vgchange -a y" and restarting all the VMs brings everything up.

Hi there, my Server: Debian 4.0, XEN xen-hypervisor-3.0.3-1-i386-pae I have successfully installed and running 13 domU. I have enough free ressources for number 14. I set it up in exactly the same way like the others. Once started this dumU Nr 14, every other domU lost its network connection. If I shutdown Nr 14, everything is working finde again. Is there a maximum number of domUs per Host?

Hi everyone, I''m getting the following boot error, when installing xen-unstable on a dual opteron 246 machine, with a Tyan 2881 Motherboard, 4GB RAM, SATA Drive and ReiserFS filesystem. The machine is a Fedora Core 4. I installed the i386 FC4 on the dual opteron, I didn''t want the 64bit yet. All my binaries are 32bit and I''m compiling it all with 32bit too. After

I''m running Centos 5.1. In order to do some software testing, I want to run about 100 virtual machines. I tried doing this on a single box but at around 30-40 I start getting issues with xen such as hotplug not responding or xen_net memory squeeze issues. So, taking another route... I would like to install 3 physical machines with Xen. I would like all of the domU''s from the 3 different physical machines to ''see each'' other network wise so I can run 35 virtual machines on each box. By default, Ce...
