I tried 2 cases with xen_emul_unplug=never:
- with xen platform disabled (xen_platform_pci=0 plus konrad patch)
and pci=nomsi
- with xen_platform_pci=1 and without pci kernel parameter
on both cases qemu crash with same error:
xen_ram_addr_from_mapcache, could not find 0x7fdecf624968

On your virtio net test you have added only 'model=virtio-net-pci'
on vif line of domU's xl cfg or you did other changes?

No, nothing more. But I'm using Xen's QEMU upstream, not vanilla QEMU.

I'm using xen's upstream qemu (master of git://xenbits.xen.org/qemu-upstream-unstable.git)


You can probably try to generate core file and use gdb to get the
backtrace to see what QEMU is trying to access.

Is there an howto for it please?


Wei.

Thanks for any reply.
