我目前正在尝试获取mac地址，但我有点困惑 . 当我尝试

import libvirt  # To connect to the hypervisor


# Connect to your local hypervisor. See https://libvirt.org/uri.html
conn = libvirt.open('qemu+ssh://%s/system' % servidor.ubicacion_ip)  # Open the hypervisor in read-only mode
# conn = libvirt.open(None)  # Open the default hypervisor in read-write mode (require
if conn == None:
    raise Exception('Failed to open connection to the hypervisor')


dom = conn.lookupByName('userid_%s_servidor_%s.qcow2' % (user.id, servidor.id))

但当我检查客人python api commands in libvirt但c api commands似乎表明它应该有办法获得mac地址？

python kvm libvirt

    好的，所以我找到了一种方法，使用libvirt输出的xml解析 .

    from salt._compat import StringIO as _StringIO
from salt.exceptions import CommandExecutionError
from xml.dom import minidom

# Connect to your local hypervisor. See https://libvirt.org/uri.html
conn = libvirt.open('qemu+ssh://%s/system' % servidor.ubicacion_ip)  # Open the hypervisor in read-only mode
# conn = libvirt.open(None)  # Open the default hypervisor in read-write mode (require
if conn == None:
    raise Exception('Failed to open connection to the hypervisor')

this_vm = conn.lookupByName('userid_%s_servidor_%s.qcow2' % (user.id, servidor.id))

macs = []
doc = minidom.parse(_StringIO(this_vm.XMLDesc(0)))
for node in doc.getElementsByTagName('devices'):
    i_nodes = node.getElementsByTagName('interface')
    for i_node in i_nodes:
        for v_node in i_node.getElementsByTagName('mac'):
            macs.append(v_node.getAttribute('address'))
    回复于
