But all about the systems that Iseeing this error, it will never force you to shutdown the entire system or break anythingor. It's just not pretty.For others, the first question is whether this reporter (Bob Tanner) really has mythe problem is, does this make xen generally unusable? The error message itself is more likelyshort, succinct links to upstream bug reports. Also upstreamThe error message is more likely than very accurate. We talk with the boy about the amd64bit system (2.6.17Debian kernel with Debian Xen hypervisor, which is simply deprecated and unmaintainedmore details inside debian) and someone else behaves "I have the same"with pae "(obviously not on amd64, except on Debian or justanother broadcast). But none of the guys at Xen responded to this ticket.long awayIf at all this is indeed a bug that makes Xen unusable, then I am really sure it iscomplexityIt's upstream, and the Xen guys have to figure it out.Now, Bob, could you please provide more information on why this makes your system unusable? You havehave you seen domU crash or your entire system? Did you manage to write exactly that?Is the kernel crumbling? Have you tried setting up "(dom0-min-mem 196)" (or more)?MB is good for dom0) and maybe 1 more) "" (dom0-cpus via /etc/xen/xend-config.sxp?Hey, Ralph Lauren

     [message part (text / plain, inline)] 
     Hello,You need to limit the main memory dom0 to two places: the Xen hypervisor and the Xend.configuration. In this case, I am limiting the memory to below 256MB:/boot/grub/menu.lst87c87<# xenhopt =---> # xenhopt = dom0_mem = 256M/etc/xen/xend-config.sxp120c120<(dom0-min-mem (dom0-min-mem 196)---> 256)After changing /boot/grub/menu.lst you really need to run update-grub and restartCar.After changing /etc/xen/xend-config.sxp you have xend restartwith restarting /etc/init.d/xend.In particular with this I have no more problems with my netback driver on some ~ 10Start dom0s Debian 4.0. (My machine has been running for over 45 daysand address ~ 20 house. There is also a significant blinkBack and forth of the population. togetherthis host.) For me, the following error does not render the package "unusable". I am veryI am happy with Debian 4.0 xen tools so I will probably install some linksdom0s in a very short time.HeyEMHa
