Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

Commit id '652a2ec6' introduced two new node device capability flags
and the ability to use those flags as a way to search for a specific
subset of a 'scsi_host' device - namely a 'fc_host' and/or 'vports'.
The code modified the virNodeDeviceCapMatch whichs allows for searching
using the 'virsh nodedev-list [cap]' via virConnectListAllNodeDevices.
However, the original patches did not account for other searches for
the same capability key from virNodeListDevices using virNodeDeviceHasCap.
Since 'fc_host' and 'vports' are self defined bits of a 'scsi_host'
device mere string comparison against the basic/root type is not
sufficient.
This patch adds the check for the 'fc_host' and 'vports' bits within
a 'scsi_host' device and allows the following python code to find the
capabilities for the device:
import libvirt
conn = libvirt.openReadOnly('qemu:///system')
fc = conn.listDevices('fc_host', 0)
print(fc)
fc = conn.listDevices('vports', 0)
print(fc)

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.
