SELinux MLS and Virtual Machines

SELinux MLS and Virtual Machines

Hello,

I was poking around in the archives looking for information on running
Virtual machines on a platform with the MLS policy.
We have a Solaris TX system that we wanted to run Virtual Box on, but Oracle
says the combination is not supported.

Would the combination be possible in the RHEL arena?
Maybe something like RHEL 6, MLS policy and Xen or the RHEL VM stuff?
Has anyone heard of such a beast?

Thanks

We are working on making RHEL6/kvm work with MLS right now.  6.1 should
support this.  You could try it out now.  You should realize that
libvirt/kvm is actually locked down more in targeted policy then it
would be in MLS.

In targeted policy the virtual machines can not attack any other virtual
machine, since each virtual machine runs with a unigue MCS label and the
images match.  In MLS policy a virtual machine would be allowed to
attack any virtual machine that it Dominates.  So two TopSecret Virtual
Machines could attack each other if you had a hypervisor vulnerability.
