[libvirt] [PATCH] python: add virConnectGetCPUModelNames to skip_impl
by Doug Goldstein 20 Nov '13

In commit de51dc9c9, we removed virConnectGetCPUModelNames from skip_impl but without this the module will always generate a symbol for libvirt_virConnectGetCPUModelNames which we don't always want.

[libvirt] [PATCH] spec: fix libvirt-docs subpackage on RHEL
by Michael Chapman 20 Nov '13

20 Nov '13

RHEL's rpmbuild wipes the docdir for a (sub-)package if any %doc directives are present, prior to copying in the marked documentation. This means we can't prepopulate this directory with the HTML documentation during the %install phase. Instead, move the HTML documentation to a temporary directory during %install and mark the contents of this temporary directory with %doc.
