使用以下命令使用本地iso来创建VM

# virt-install --name test --ram 8192 --vcpus 4 \
-f /root/test.qcow2 --os-type linux \
--os-variant rhel7 --network bridge=virbr0 \
--cdrom CentOS-7-x86_64-DVD-1810.iso \
--graphics vnc,listen=0.0.0.0,port=5920

输出信息

Traceback (most recent call last):
  File "/usr/share/virt-manager/virt-install", line 29, in <module>
    import virtinst
  File "/usr/share/virt-manager/virtinst/__init__.py", line 90, in <module>
    from virtinst.distroinstaller import DistroInstaller
  File "/usr/share/virt-manager/virtinst/distroinstaller.py", line 23, in <module>

    from .exceptions import InvalidURL
  File "/usr/lib/python2.7/site-packages/requests/exceptions.py", line 10, in <module>
    from urllib3.exceptions import HTTPError as BaseHTTPError
  File "/usr/lib/python2.7/site-packages/urllib3/__init__.py", line 10, in <module>
    from .connectionpool import (
  File "/usr/lib/python2.7/site-packages/urllib3/connectionpool.py", line 31, in <module>
    from .connection import (
  File "/usr/lib/python2.7/site-packages/urllib3/connection.py", line 45, in <module>
    from .util.ssl_ import (
  File "/usr/lib/python2.7/site-packages/urllib3/util/__init__.py", line 4, in <module>
    from .request import make_headers
  File "/usr/lib/python2.7/site-packages/urllib3/util/request.py", line 5, in <module>
    from ..exceptions import UnrewindableBodyError
ImportError: cannot import name UnrewindableBodyError

只需要看最后一行ImportError: cannot import name UnrewindableBodyError，整个的输出报错多为.py结尾的，说明与python有关，python中需要import的只有python库，这是python的库出现了小问题，具体问题不详，解决方法如下：

使用pip和yum将python相关的库删除

# pip uninstall requests
# pip uninstall urllib3
# yum remove python-urllib3
# yum remove python-requests

确认删除成功：执行之后没有输出即可

# rpm -qa | grep requests 
# pip freeze | grep requests

用yum的方式将python库安装

# yum install python-urllib3
# yum install python-requests

然后再去重新执行创建VM
