https://bugzilla.kernel.org/show_bug.cgi?id=206579 --- Comment #12 from Paolo Bonzini (bonzini@xxxxxxx) --- Comment on attachment 287579 --> https://bugzilla.kernel.org/attachment.cgi?id=287579 Patched rc3 dmesg crash output Based on the crashdump the failure seems to be at: if (!svm->vcpu.arch.apic->regs) return -EINVAL; in avic_init_backing_page. This suggests refining the patch to look like this: ----- if (!avic && !irqchip_in_kernel(vcpu->kvm)) return 0; ret = avic_init_backing_page(&svm->vcpu); ----- muncrief, please in addition to testing the patch can you include the qemu command line (from "ps aux")? I see nothing in your libvirt XML that suggests disabling KVM's in-kernel emulation of the local APIC (and the fact that EPYC-IBPB disables x2APIC also suggests that it's disabled), so we might have two bugs here. What is your QEMU version? -- You are receiving this mail because: You are watching the assignee of the bug.
