Re: [Xen-devel] Regression PCI passthrough from 4.5.5 to 4.6.0-rc1

Attached ZIP file contains hypervisor and qemu log.
Thanks, so the guest is indeed unmasking the MSIX table entries before
MSIX is enabled, and QEMU only registers the entries with Xen once MSIX
is enabled:

The patch I've sent earlier (which I'm also attaching to this email)
implements the first solution for QEMU.
Can you please give it a try?

Results are inconsistent. On the first run it seemed OK (Windows had a problem of its own). On a later run, Windows again hang during boot. qemu logs are different on both runs but I was not able to separate different runs in xl-dmesg.

Regards Andreas
