Xen and SELinux: unable to access disk file

Hello,

I'm doing some custom file system work. I'm using RHEL5, and I'm
trying to start up a Xen VM using a disk file mounted on my file
system driver. I'm getting the following error:

setroubleshoot: SELinux is preventing xen (/usr/sbin/tapdisk)
"getattr" to /mnt/fs/test (unlabeled_t). For complete SELinux
messages. run sealert -l c250973f-bfd9-45e8-8269-d0f68f383dc6

setroubleshoot: SELinux is preventing /usr/sbin/tapdisk (xend_t)
"read write" access to test (unlabeled_t). For complete SELinux
messages. run sealert -l 6710ec29-ec01-47c1-ad4b-af7021de862e

an 'ls' of the file shows the following:

-rwxr-xr-x root root system_u:object_r:unlabeled_t test

I have SELINUX=permissive in my /etc/sysconfig/selinux and /etc/
selinux/config files, which I though was supposed to prevent SELinux
from enforcing policy.

Finally, running sealert only gives me a "failed to connect to server"
error

Thanks,
Scott
