http://bugzilla.novell.com/show_bug.cgi?id=567306 http://bugzilla.novell.com/show_bug.cgi?id=567306#c0 Summary: xen-system crashes when domU run's heavy io Classification: openSUSE Product: openSUSE 11.2 Version: Final Platform: x86-64 OS/Version: openSUSE 11.2 Status: NEW Severity: Critical Priority: P5 - None Component: Xen AssignedTo: jdouglas@novell.com ReportedBy: rob@sailors.ch QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Opera/9.80 (Windows NT 5.1; U; de) Presto/2.2.15 Version/10.10 hello i built a system with opensuse 11.2. had problems to bring domU's up, but found help here - thanks that for! now, if i stress the domU with just a "tar -xcvf file.tar (file.tar has 50G) the system hangs - it's restartable and i can reproduce the error... to be shure thats not a hw-problem, i did the same in domain0, work fine, no problem. i used files as space for the disks in domU. then i switched to lvm2-lv's problem persits. i have seen bugs 553690, 559047 and tried mem=4G and mem=3G (as the system only has 3gb ram), both both didn't help. so my question: is there a way to make the xen-system stable without to patch the xen kernel? i'm not quit familar with building a patched xen-kernel (the xen.gz). do i have to wait for a new xen-kernel? Reproducible: Always Steps to Reproduce: 1. build opensuse 11.2 system 2. install xen-hypervisor, reboot with xen 3. install domU (goes fine with my system) 4. bring domU under stress with heavy io (expand a tar or so). Actual Results: system crashes, neither domain-0 or domu brigs a response (does nor respond to ping) Expected Results: stable sytem -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
