https://bugzilla.novell.com/show_bug.cgi?id=350051 Summary: -xenpae kernels seem to be unusable when running on more than one VCPUs Product: openSUSE 10.3 Version: Final Platform: PC OS/Version: openSUSE 10.3 Status: NEW Severity: Critical Priority: P5 - None Component: Xen AssignedTo: cgriffin@novell.com ReportedBy: nice@titanic.nyme.hu QAContact: qa@suse.de Found By: Other As I mentioned in https://bugzilla.novell.com/show_bug.cgi?id=343181#c19 When I run a Linux system on a -xenpae kernel with more VCPUs either as dom0 or domU, the system will be HIGHLY unstable. I tried it with both the i386's /boot/xen-pae.gz and x86_64's /boot/xen.gz, and the results are the same. Kernel compiling on such a system is equal to suicide for example. First some segmentation fault occurs, then the kernel space's CPU load goes very high, and, at last, the system becomes totally unresponsive. I will attach a typical screenshot (which is combined of more screenshots) of our production mailserver's (SuSE Linux 8.2(!)) tty10 when running paravirtualized under the mentioned corcumstances as a domU. It crashed 4-5 times a day, when running with more VCPUs with a -xenpae kernel. Now it has run for some days without any problem with one VCPU. Running this 32 bit system on a 64bit kernel (either with one or more VCPUs) is OK as well. 64 bit kernels seem to be unaffected by this problem. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
