Public bug reported: When starting up a single xen paravirtualized domain I sometimes get the attached kernel panic - not everytime but it is reproduceable, it happens roughley once a day.
The machine completely freezes and must be reset (powercycle). A similar problem has been reported on Debian: http://lists.debian.org/debian-kernel/2007/02/msg00281.html - with a potential workaround (which I shall try shortly: http://lists.debian.org/debian-kernel/2007/02/msg00291.html In the Debian bug, Gerald mentions: """ A similar problem was reported to the xen users list also - with the default "file a bug against debian" answer. http://lists.xensource.com/archives/html/xen-users/2007-02/msg00001.html """ $ uname -a Linux ubt 2.6.19-4-generic #2 SMP Thu Apr 5 06:06:18 UTC 2007 i686 GNU/Linux $ dpkg -l |grep xen ii libc6-xen 2.5-0ubuntu14 GNU C Library: Shared libraries [Xen version ii libxen3.0 3.0.3-0ubuntu10 library interface for Xen, a Virtual Machine ii python-xen3.0 3.0.3-0ubuntu10 python bindings for Xen, a Virtual Machine M ii ubuntu-xen-desktop 0.0.1-2ubuntu3 Xen software for running on servers. ii xen-docs-3.0 3.0.3-0ubuntu10 documentation for XEN, a Virtual Machine Mon ii xen-hypervisor-3.0-i386 3.0.3-0ubuntu10 The Xen Hypervisor for i386 ii xen-image-2.6.19-4-generic 2.6.19-2ubuntu7 Linux 2.6.19 image on PPro/Celeron/PII/PIII/ ii xen-ioemu-3.0 3.0.3-0ubuntu10 XEN administrative tools ii xen-tools 3.1-1ubuntu1 Tools to manage debian XEN virtual servers ii xen-utils-3.0 3.0.3-0ubuntu10 XEN administrative tools ii xenman 0.5-2.1 A graphical Xen management tool ----------- [cut here ] --------- Message from [EMAIL PROTECTED] at Mon Jul 2 09:42:23 2007 ... ubt kernel: [73006.254782] ------------[ cut here ]------------ Message from [EMAIL PROTECTED] at Mon Jul 2 09:42:23 2007 ... ubt kernel: [73006.254816] kernel BUG at drivers/xen/core/evtchn.c:481!
