Description of problem:

Satellite generated virt-who config updates the global virt-who configuration which does recognize no_proxy.

even with no_proxy=* in /etc/virt-who.conf, virt-who does not ignore the default proxy configured in /etc/rhsm/rhsm.conf

Version-Release number of selected component (if applicable):

satellite 6.10.7
virt-who-0.28.10-1.el7_9.noarch

I have tested in 6.10, later versions should have similar impact as well.

How reproducible:
100%

Steps to Reproduce:

1. Configure a proxy in /etc/rhsm/rhsm.conf which is default proxy.

2. Create virt-who configuration in satellite GUI with "Ignore Proxy" = *

3. Deploy virt-who configuration and it will set "no_proxy=*" in /etc/virt-who.conf

3. Check /var/log/rhsm.log

Actual results:

• /etc/virt-who.conf updated with "no_proxy=*"

• virt-who failed to send the guest-host mapping , it still tried to connect via proxy and ignored the "no_proxy" option:

~~~

Expected results:

• Satellite virt-who configuration should update "/etc/virt-who.d/virt-who-config-X.conf" with "rhsm_no_proxy=*" instead updating the global configuration.

Additional info:

Workaround :

• Add "rhsm_no_proxy=*" in /etc/virt-who.d/virt-who-config-X.conf , where X is the latest generated configuration.
• restart virt-who
