+Subject: [PATCH] v2v: Print nbdcopy command in debug output
+
+Commit fd1148f795 ("v2v: Implement --parallel=N for parallel disk
+copies") changed how we run nbdcopy from using Tools_utils.run_command
+to calling Unix.execvp directly.  However a side effect of this is
+that we no longer printed the nbdcopy command that we were about to
+run in verbose mode.  Fix this by printing it in debug output.
+
+Reported-by: Ming Xie
+Fixes: https://issues.redhat.com/browse/RHEL-86022
+Fixes: commit fd1148f79581b148525eb12154aef7603ccf0baa
+(cherry picked from commit 802172c1a868e9287416d26e77a94d01c2d7b871)
