Support virDomainGetIOThreadsInfo and virDomainIOThreadsInfoFree
Add support for the libvirt_virDomainGetIOThreadsInfo method. This
code mostly follows the libvirt_virDomainGetVcpuPinInfo method, but
also takes some from the libvirt_virNodeGetCPUMap method with respect
to building the cpumap into the returned tuple rather than two separate
tuples which vcpu pinning generates
Assuming two domains, one with IOThreads defined (eg, 'iothr-gst') and
one without ('noiothr-gst'), execute the following in an 'iothr.py' file:
import libvirt
con=libvirt.open("qemu:///system")
dom=con.lookupByName('iothr-gst')
print dom.ioThreadsInfo()
dom2=con.lookupByName('noiothr-gst')
print dom2.ioThreadsInfo()
$ python iothr.py
[(1, [False, False, True, False]), (2, [False, False, False, True]), (3, [True, True, True, True])]
[]
