For Satellite:
If the Satellite server is “connected”, then it will initiate outbound connections to ports 80 and 443 on the Red Hat Network (RHN) hosted service (rhn.redhat.com / satellite.rhn.redhat.com).

Devlabel is a script which manages symbolic links to storage devices on your system. This is accomplished by utilizing the inherent unique identifiers (UUID) that each device should have in order to maintain a correctly pointing symlink in the event that the device name changes (eg. /dev/sdc1 becomes /dev/sdd1).
By adding entries [...]

Yes, to achieve this, pass the shared disk with the w! option.
For example in /etc/xen/<config file for vm> do the following:
disk = [ "file:/var/lib/xen/images/hostOS.img,hda,w""file:/var/lib/xen/images/qdisk.img,sda,w!"
Make the setting, then boot up all nodes. Create qdisk fs, then check that all nodes can read the qdisk fs:
