We need to have a 

  /var/lib/libvirt/boot

directory added to the SELinux Policy for KVM/QEMU for storing kernel+initrd
files for purposes of booting the installer. KVM/QEMU should have ability to
read files in that directory, but not write to them.



+++ This bug was initially created as a clone of Bug #445854 +++

Description of problem:
virt-install --location produces avc: denied { read } for pid=5220
comm="qemu-kvm" name="virtinst-vmlinuz.dOPar5" dev=sda1 ino=196841
scontext=system_u:system_r:qemu_t:s0
tcontext=unconfined_u:object_r:user_tmp_t:s0 tclass=file 

kernel and initrd are downloaded to /var/tmp/ and get wrong SElinux context
user_tmp_t instead of expected 

Version-Release number of selected component (if applicable):
kvm-65-1.fc9
python-virtinst-0.300.3-5.fc9
selinux-policy-targeted-3.3.1-42.fc9

How reproducible:
install KVM guest using --location option

Steps to Reproduce:
1. virt-install -n testVM -r 768 -f /var/lib/libvirt/images/testVM.img -s 6
--vnc  --accelerate -v --os-type=linux --arch=i686 -w network:default -l

This shouldn't really use /var/lib/libvirt/images since that's for disk images.
THe kernel & initrd should really be in their own directory. I'll get Dan to add
a new directory to the SELinux policy for this
