libvirt credentials

使用libvirt进行远程管理(带身份认证),getdominfo.py

python getdominfo.py xen+tcp://192.168.103.10:16509/

代码如下：

#!/usr/bin/python

import sys, getpass, libvirt

import pdb

#pdb.set_trace()

uri = sys.argv[1]

mydata = "" 

def getCredentials(credentials, data):

        for credential in credentials:

                print credential[1] + ":",

                if credential[0] == libvirt.VIR_CRED_AUTHNAME:

                        data = sys.stdin.readline()

                        data = data[0:len(data)-1]

                        credential[4] = data

                elif credential[0] == libvirt.VIR_CRED_PASSPHRASE:

                        credential[4] = getpass.getpass("")

                else:

                        return -1

        return 0

flags = [libvirt.VIR_CRED_AUTHNAME,libvirt.VIR_CRED_PASSPHRASE]

auth = [flags,getCredentials,mydata]

#localconn = libvirt.open(None)

#dom = localconn.lookupByName(vmname)

conn = libvirt.openAuth(uri,auth,0)

#dom.migrate(remoteconn,libvirt.VIR_MIGRATE_LIVE,None,uri,0)

for id in conn.listDomainsID():

        dom = conn.lookupByID(id)

        state = dom.info()

        print "Dom %s  State %s,mem:%s,3:%s,vCPUs:%s,5:%s" % ( dom.name(), state[0],state[1],state[2],state[3],state[4])
