The libvirt zonefile for firewalld (added in commit 3b71f2e4) does the
following:
1) lists specific services it wants to allow, then
2) uses a lower priority <reject/> rule to block all other services to
the host, and then finally,
3) relies on the zone's default "accept" policy to, accept all
forwarded traffic (since forwarded traffic is ignored by the
slightly higher priority <reject/> rule in (2)).
I had assumed that icmp traffic was either being allowed at the top of
the rules, or that it would be ignored by the <reject/> rule and
passed by the default accept policy (similar to forwarded traffic),
but this assumption was incorrect; the <reject/> rule does block icmp
traffic. This became apparent when DHCPv6 which requires ICMPv6 in
addition to udp/dhcpv6) failed to work.
This all means that in order to achieve our original goal of "similar
behavior to a default reject policy, but also allowing forwarded
traffic", we need to add rules to allow all icmp and icmpv6 traffic to
the libvirt zone, and that's what this patch does.
This is a further refinement of the resolution to

This is basically an old artefact from 24b0821926 when the idea
was:
1) Build device string only to see if chardev has any -device
associated with it and thus if device_del is needed
2) Detach chardev using chardev_del
Now, that DEVICE and DEVICE_DELETED capabilities are assumed for
every domain 1) does not make sense anymore.

The guestfwd channels are -netdevs really. Hotunplug them as
such. Also, DEVICE_DELETED event is not triggered (surprisingly,
since we're not issuing device_del rather than netdev_del) and
associated chardev is removed automagically too. This means that
we need to do qemuDomainRemoveChrDevice() minus monitor call to
remove the chardev.

So far we are passing @chr to qemuBuildChrDeviceStr. This is
suboptimal (in fact wrong) because @chr is just parsed XML
definition provided by user which by definition may lack some
information. On the other hand, @tmpChr is the one that was found
using @chr in domain definition so it contains the same amount of
information or more.
