Little debugging showed that we don't enable acl support. So this patch series provides option to enable/disable posix acl support. By default it is disabled. I have run blogbench and pjdfstests with posix acl enabled and things work fine. Luis, can you please apply these patches, and run virtiofsd with "-o posix_acl" and see if it fixes the failure you are seeing. I ran the steps you provided manually and it fixes the issue for me.
