[Bug 92291] kvm/guest crashes when smp > 1 with AMD FX8300; with host kernel oops from abrt as well
https://bugzilla.kernel.org/show_bug.cgi?id=92291 --- Comment #10 from Mark --- well thanks very much guys, I'll cautiously say that a patched guest kernel seems to resolve it :-) the bug seemed to appear even when the host is untainted; serial log says [ 375.989736] divide error: [#1] SMP that's a Kubuntu partition that manages without the proprietary drivers while Fedora won't seem to give graphics properly with nouveau; not entirely satisfactory of course given that I've now had to modify a virtual machine that it was important to try to avoid modifying for testing purposes; although definitely better than crashing :-) do we keep the bug report open so that the host kvm handling bug gets fixed too / is this the right place to report that? -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
