I have scoured the web and can't find anything on the topic: Is IPv6
supported for remote image targets?
For example:
guestfish --format=raw --ro -a
rbd://[fd00::cefc:1]:6789/images/CentOS-7-x86_64-GenericCloud-1901
Does not work citing the following:
libguestfs: trace: set_verbose true
libguestfs: trace: set_verbose = 0
libguestfs: create: flags = 0, handle = 0x5560231bdfb0, program = guestfish
libguestfs: trace: set_pgroup true
libguestfs: trace: set_pgroup = 0
libguestfs: trace: add_drive "images/CentOS-7-x86_64-GenericCloud-1901"
"readonly:true" "format:raw" "protocol:rbd" "server:tcp:[fd00::cefc:1]:6789"
libguestfs: creating COW overlay to protect original drive content
libguestfs: trace: get_tmpdir
libguestfs: trace: get_tmpdir = "/tmp"
libguestfs: trace: disk_create "/tmp/libguestfs3pGMi6/overlay1.qcow2"
"qcow2" -1
"backingfile:rbd:images/CentOS-7-x86_64-GenericCloud-1901:mon_host=[fd00::cefc:1]\:6789:auth_supported=none"
"backingformat:raw"
libguestfs: command: run: qemu-img
libguestfs: command: run: \ create
libguestfs: command: run: \ -f qcow2
libguestfs: command: run: \ -o
backing_file=rbd:images/CentOS-7-x86_64-GenericCloud-1901:mon_host=[fd00::cefc:1]\:6789:auth_supported=none,backing_fmt=raw

Other variations of the IPv6 address fail in a similar fashion, some
even failing with the URI parser. It seems as though everything after
the first : in the address is getting parsed as args.
Changing this IPv6 address over to a hostname allows the command to work.
Unfortunately I'm working within the confines of OpenStack and some of
it's requests here and my Ceph cluster is v6-only so I can't easily just
have it use hostnames to solve the issue.
