If a 8021.Qbh network device supports SRIOV and its VF is being used in pci passthrough mode, when the guest is shutdown or destroyed, the PF inteface is also brought down. qemuDomainHostdevNetConfigRestore() finds out the PF for provided hostdev (which is VF) and passes it to virNetDevPortProfileDisassociate() as linkdev. Later, linkdev gets passed to virNetDevSetOnline() where the interface is brought down by clearing IFF_UP flag. Bringing down a PF, when only VF is being brought down is not expected behavior. This patch adds a check so that virNetDevSetOnline() is called only for PF and not if device is a VF. Signed-off-by: Nishank Trivedi <nistrive@cisco.com>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
