Re: [Xen-devel] Bug for Xen-3.3.0-rc2: libpci read error. No emulation.

[Yuji Shimada <shimada-yxb@xxxxxxxxxxxxxxx>]

libpci error handling has been fixed in the latest ioemu-remote and
ioemu in xen-3.3.0-rc3-pre. If you test them, libpci read error
will disappear.

But I think hotplug issue is not caused by libpci read error.

I tested xen-3.3.0-rc3-pre (changeset:18212) with ioemu-remote
(commit:0a8ce1e7a87126a544f23209ef3a87346601f18a).  "libpci read
error" did not appear, but hotplugged NIC did not work.  I checked
/proc/interrupts on guest os, and found that guest os received msi
only once.

I try to find out the reason of the issue.

Thanks
