libvirt users - Dec 2011 - How to connect to a remote VM ESXi server with Python language?

Hi, Dear Mr/Mrs.

I have trouble in connecting to a VM ESXi server with python.

I am a developer using libvirt to control remote VM ESXi with python
language. But I am not able to connect to a remote VM ESXi server.

I make my try to solve this issue:

1: I use the function libvirt.Open() to open the remote VM ESXi Server, but
I don't know how to input the password. It seems that there is no parameter
for password input. 

2: I use "virsh connect ---". It is succeed when it is executed on
locale
machine manual, but failed when I invoke this command in python environment.
I use "subprocess.Popen" to execute the command "virsh", but
this function
would be hung on after command "communicate" executed.

-bash-4.1# python

Python 2.6.6 (r266:84292, May 20 2011, 16:42:11) 

[GCC 4.4.5 20110214 (Red Hat 4.4.5-6)] on linux2

Type "help", "copyright", "credits" or
"license" for more information.
>>> from subprocess import Popen,PIPE,STDOUT
>>> command=['virsh', '-c',
'esx://192.168.58.144/?no_verify=1','list',
'--all']
>>> p=Popen(command, stdin=PIPE,stdout=PIPE, stderr=STDOUT)
>>> output = p.communicate()[0]
How to fix it?

 

Thanks for help!

Best regards!

Let's just ignore your second try with virsh. The problem with your
first try is that you need to use libvirt.openAuth() instead of
libvirt.open(). openAuth() allows to pass credentials via a callback
mechanism.

There is a Python example in the libvirt codebase that does this, see
