<title>Tips and fixes for QEMU on RHEL</title>
<para>If you are testing OpenStack in a virtual machine, you must configure Compute to use qemu
without KVM and hardware virtualization. The second command relaxes SELinux rules to
allow this mode of operation (<link
xlink:href="https://bugzilla.redhat.com/show_bug.cgi?id=753589">
https://bugzilla.redhat.com/show_bug.cgi?id=753589</link>). The last two commands
here work around a libvirt issue fixed in Red Hat Enterprise Linux 6.4. Nested
virtualization will be the much slower TCG variety, and you should provide lots of
memory to the top-level guest, because the OpenStack-created guests default to 2GM RAM
with no overcommit.</para>
<note><para>The second command, <command>setsebool</command>, may take a while.
