Hi all, This is my first post to the list, I hope someone out there can help! I am running xen 3.0.3, with CentOS 5.2 based Dom0 (kernel-xen-2.6.18-92.1.22.el5) Recently I have noticed some complete system lockups on a few different servers. Neither Dom0 or any of the guests respond to pings, connecting a keyboard and monitor to the system only shows a blank screen. Nothing is written to logs

...or setting to the same value as dom0_mem disables memory balloon correct? I cant seem to think of a reason why I would want memory ballooning. Also setting dom0-min-mem should that be done in xend-config.sxp or on the kernel command line? -- Nick Anderson <nick@anders0n.net> http://www.cmdln.org http://www.anders0n.net _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Recently I ran into a situation where an ocfs2 (1.4) volume was reporting it was out of space when it was not. Deleting some files helped short term but the problem quickly comes back. I believe this is due to the fragmentation bug that I have seen references to in the mailing list archive. I am trying to reproduce the problem on a test system so that I can validate that upgrading to 1.6

Hi all. We just put a relative large server in operation (for our measures ;-) ), a 4x Dual Core / Intel with 16GB Ram and a 3ware 9550SX SATA-RAID with 4 drives. Operating system for the Dom0 is an up-to-date gentoo linux. Everything runs really fine, there are 4 Domu''s running, 1x gentoo and 2x debian and 1x Windows Server 2003. DomU''s are running blazing fast in normal

All, I''ve got one Xen server running CentOS 5, with 3 CentOS virtual machines on it. I have what I hope is a simple question: I''d like to backup the virtual machines. I don''t care about anything but the ability to restore a couple of files and be able to be back up and running quickly. At some point I''ll have a spare server ready to migrate running Xen

Hello Everyone, We have noticed that one of our servers xen Dom0 is restarting idiopathically. Atleast, we are not able to analyze the cause. I have checked the logs but couldn''t find anything relating to it. Are there any tools such as kdump (which doesn''t seem to work on xenified kernels) for catching the kernel crash snapshot.

Hi. I entered one of our domU tonight and see following problem: # iowait -k 5 avg-cpu: %user %nice %system %iowait %steal %idle 0.00 0.00 0.00 100.00 0.00 0.00 Device: tps kB_read/s kB_wrtn/s kB_read kB_wrtn sda1 0.00 0.00 0.00 0 0 sda2 0.00 0.00 0.00 0

I realize this might be one of those religious topics, but is there any good rule of thumb as to how to setup storage for a Xen domU? Without really knowing any better, I''m basically going to make a disk image of the OS and the create a ''data'' partition on my raid 5 volume for each virtual machine. This is for use at home, so in reality it probably doesn''t
