Re: [Xen-devel] HVM domain with VT-d passthrough fails to boot (was: [PATCH 2/2] ioemu: Enable guest OS to program D0-D3hot states of an assigned device)

[Yuji Shimada <shimada-yxb@xxxxxxxxxxxxxxx>]

Thank you for sending the logs.

Qemu is killed by the kernel due to segmentation fault.

[   94.509681] qemu-dm[2578]: segfault at c ip 00000000004734a4 sp 
00007fff31294610 error 4 in qemu-dm[400000+f4000]

My patch changed "struct PCIDevice" in hw/pci.h.
"make -C tools clean" is needed before "make".
If you did not execute "make -C tools clean", it might cause the
issue.

If "make -C tools clean" does not fix the issue, could you investigate
why segmentation fault occurs. Starting qemu-dm under gdb server will
help to investigate. Configuring kernel to create core dump on
segmentation fault will also help.

Thanks,
