Hmm, reading the flow for peer2peer here:
https://libvirt.org/migration.html#flowpeer2peer
which says:
"Note that the source libvirtd uses its own credentials (typically root)
to connect to the destination, rather than the credentials used by the
client to connect to the source; if these differ, it is common to run
into a situation where a client can connect to the destination directly
but the source cannot make the connection to set up the peer-to-peer
migration."
So, somehow libvirtd daemon on source is not able to pick the
credentials. I'll try qemu+tcp with the below configs in libvirtd.conf
(note: the auth_tcp = "none" because, I'm doing the test in a trusted
network).
listen_tls = 0
listen_tcp = 1
auth_tcp = "none"
