[libvirt-users] how to install libvirt-python

[Mahmood Naderan]

OK. I am trying to install virt-manager from source but found it difficult!

So I decided to install from repo.

# yum install virt-manager libvirt

And I installed all of them.
However when I start virt-manager, I get this error



Error polling connection 'qemu:///system': internal error Cannot find suitable emulator for x86_64

However I have installed Qemu from source. For example

$ /usr/local/bin/qemu-x86_64 -version
qemu-x86_64 version 1.6.90, Copyright (c) 2003-2008 Fabrice Bellard


So what is the problem here?

That's because installing libvirt-python doesn't create any directory or
file named exactly libvirt-python.  For an example of what DOES get
installed:

# rpm -ql libvirt-python
/usr/lib64/python2.7/site-packages/libvirt.py
/usr/lib64/python2.7/site-packages/libvirt.pyc
/usr/lib64/python2.7/site-packages/libvirt.pyo
/usr/lib64/python2.7/site-packages/libvirt_lxc.py
/usr/lib64/python2.7/site-packages/libvirt_lxc.pyc
/usr/lib64/python2.7/site-packages/libvirt_lxc.pyo
/usr/lib64/python2.7/site-packages/libvirt_qemu.py
/usr/lib64/python2.7/site-packages/libvirt_qemu.pyc
/usr/lib64/python2.7/site-packages/libvirt_qemu.pyo
/usr/lib64/python2.7/site-packages/libvirtmod.so
/usr/lib64/python2.7/site-packages/libvirtmod_lxc.so

/usr/share/doc/libvirt-python-1.1.3.1/python/esxlist.py
/usr/share/doc/libvirt-python-1.1.3.1/python/topology.py

Also, you can do:


$ python
>>> import libvirt
>>> help('libvirt')

and if that succeeds, then python found your installed libvirt bindings.
