xen-pciback: a fix and a workaround

[PATCH v2 0/2] xen-pciback: a fix and a workaround

Posted by Jan Beulich 4 years, 8 months ago

The first change completes a several years old but still incomplete
change. As mentioned there, reverting the original change may also
be an option. The second change works around some odd libxl behavior,
as described in [1]. As per a response to that mail addressing the
issue in libxl may also be possible, but it's not clear to me who
would get to doing so at which point in time. Hence the kernel side
alternative is being proposed here.

As to Konrad being on the Cc list: I find it puzzling that he's
listed under "XEN PCI SUBSYSTEM", but pciback isn't considered part
of this.

1: redo VF placement in the virtual topology
2: reconfigure also from backend watch handler
