This adds a binding for the virConnectOpenAuth() api in the python API. This allows a python function to be used as the callback.
This short example code illustrates the use of the API from a python app which wants to support username/password credentials only.
from getpass import getpass mydata = "Hello"
def getCred(creds, data): print "yes" print str(creds) for cred in creds: print cred[1] + ": ", if cred[0] == libvirt.VIR_CRED_AUTHNAME: data = sys.stdin.readline() data = data[0:len(data)-1] cred[4] = data elif cred[0] == libvirt.VIR_CRED_PASSPHRASE: cred[4] = getpass("") else: return -1 return 0
uri = "qemu+tcp://localhost/system" conn = libvirt.openAuth(uri, [[libvirt.VIR_CRED_AUTHNAME, libvirt.VIR_CRED_PASSPHRASE], getCred, mydata], 0)
print str(conn.listDefinedDomains())
Nice. One nit:
