Description Mijax 2010-04-10 09:55:07 UTC 
Summary:

SELinux is preventing /usr/bin/vmnet-natd "execute_no_trans" access on
/usr/bin/vmnet-natd.

Detailed Description:

SELinux denied access requested by vmnet-natd. It is not expected that this
access is required by vmnet-natd and this access may signal an intrusion
attempt. It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 5 Miroslav Grepl 2010-04-26 09:20:47 UTC 
Mijax,
probably you also need to update selinux-policy-targeted package.

I have:

# rpm -q selinux-policy-targeted
selinux-policy-targeted-3.6.32-113.fc12.noarch

# sesearch -A -s vmware_host_t -t vmware_host_exec_t -c file -p execute_no_trans
Found 1 semantic av rules:
   allow vmware_host_t vmware_host_exec_t : file { ioctl read getattr lock execute execute_no_trans entrypoint open } ;
