The built failure on amd64 is due to virnetsockettest failing with:

too long for unix socket: Cannot allocate memory
since the socket path doesn't fit in UNIX_PATH_MAX. Since exceeding the
path shouldn't't be fatal I'm using the attached patch.

Wrong place to be checking - virAsprintf() only fails on OOM (malloc
failure), not on size fit, so your skip is unlikely to be hit. I agree
that it's okay to skip the test if run in a subdirectory so deep that a
Unix socket cannot be created with a name that long, but that should be
done strlen() check just before virNetSocketNewListenUNIX, not by
looking for malloc failure. And since we're most likely not out of
memory, that may mean we also have a bug to fix in our error reporting
quality within virNetSocketNewListenUNIX.
