Hi again Michal,
I have more information to share.
I think I can confirm that the patches are actually fixing the
credentials problem and they are passed along.
This is the content of test.log with libvirt-php output:
[2016-09-05 22:06:05 libvirt-php/core ]: libvirt_connect: credentials
index 2
[2016-09-05 22:06:05 libvirt-php/core ]: libvirt_connect: credentials
index 5
[2016-09-05 22:06:05 libvirt-php/core ]: libvirt_connect: Found 2
elements for credentials
[2016-09-05 22:06:05 libvirt-php/core ]:
libvirt_virConnectAuthCallback: cred 0, type 5, prompt Enter
Administrator's password for 192.168.7.2 challenge 192.168.7.2
[2016-09-05 22:06:05 libvirt-php/core ]:
libvirt_virConnectAuthCallback: result somepass (16)
Of course then the process is crashing and the connection is aborted so
I believe that the patches work fine (they fix the connection
credentials not passed along issue) but once this is fixed the other
problem is uncovered.
I also took a trace of virsh to compare the behavior and I found that
right after trying to open the file
"/etc/openwsman/openwsman_client.conf" which doesn't exist, the network
connection to the Hyper-V host starts:

While in the case of libvirt-php, it will crash and abort the
connection. If you want me to send you the full virsh trace, just let
me know.
Also, not sure if it worth mention it and I guess you are aware that
libvirt depends on openwsman to connect to a Hyper-V host.
Thanks in advance for your help.
