+++ This bug was initially created as a clone of Bug #1218958 +++

If you have a connection is configured as 'host.domain', and open the VM details the dialog opens but a Python traceback is shown:

Error launching details: 'host.domain' does not appear to be an IPv4 or IPv6 network

Traceback (most recent call last):
  File "/usr/local/share/virt-manager/virtManager/engine.py", line 791, in _show_vm_helper

The details can still be modified however.

This is with:
virt-manager 1.2.0
libvirt 1.2.15


This issue is 100% reproducible.

Reverting this commit worksaround the issue: https://git.fedorahosted.org/cgit/virt-manager.git/commit/virtManager/sshtunnels.py?id=a2d453f3e20d103a4767394300c5183fde9a6bb4

It seems the 'host' is not resolved before it's passed to ipaddr.IPNetwork().

could you verify if this works for you?

I am going to do more tests here and propose it upstream later today:

Indeed that works for me, but shouldn't _is_listen_any() get the same treatment?

Thanks.

--- Additional comment from Giuseppe Scrivano on 2015-05-06 08:15:18 EDT ---

is_listen_any() is accessing only self.gaddr, which is supposed to be already an IP address.

The same thing is done in _is_listen_localhost in case host=None

Sorry, I have a setup to test this before the release, but I forgot :/
