解决方法:

I  also had the problem with RHEL 6.2 running on a VM on ESX. Apparently  authentication via a fingerprint reader is enabled by default in RHEL 6  and this somehow causes problems in a virtual environment. You can  confirm that it is enabled by running:


# grep -i fprintd /etc/sysconfig/authconfig

USEFPRINTD=yes


osI was able to disable it by running this command:

# authconfig --disablefingerprint --update


Another grep confirms it:

# grep -i fprintd /etc/sysconfig/authconfig

USEFPRINTD=no
