In #20602 we added the ability to change ARPCHECK in network settings.
This was missing and later added in RH7, but was missing from RH8, since
RH8 support was added before we updated the RH7 support.
This fixes#57047
In order to support creating VMs with disk on more storage pools like
iSCSI, disks, LVM, RBD, etc, virt.init needs to handle disks not only as
files, but also as libvirt volumes.
In order to get all possible capabilities from a host, the user has to
call virt.capabilities, and then loop over the guests and domains
before calling virt.domain_capabilities for each of them.
This commit embeds all this logic to get them all in a single
virt.all_capabilities call.
