Version-Release number of selected component (if applicable):

python-virtinst-0.500.2-1.fc13.noarch
libvirt-0.7.6-1.fc13.i686

How reproducible:

Happens once.  Second time I got a different bug, which I'm
going to file separately.

Comment 1 Richard W.M. Jones 2010-03-08 21:28:52 UTC

The other bug is 571576.

In /var/log/libvirt/qemu/F12x64.log, I see the same thing each
time (for both bugs):

Comment 2 Richard W.M. Jones 2010-03-08 21:33:26 UTC

This is NOT an selinux problem.  I tried with selinux=Permissive.

However it does seem to be a simple permissions problem.  virt-install
downloads the files here:

# ls -alZ /var/lib/libvirt/boot/
drwx--x--x. root root system_u:object_r:virt_content_t:s0 .
drwxr-xr-x. root root system_u:object_r:virt_var_lib_t:s0 ..
-rw-------. root root unconfined_u:object_r:virt_content_t:s0 virtinst-vmlinuz.YWZ0KF

and qemu (running as the 'qemu' user) cannot access that file
because the permissions are 0600.

Is there some reason why this file should be 0600?  There is
no secret -- the kernel is a file downloaded off a public
internet site :-)

Comment 3 Richard W.M. Jones 2010-03-08 21:33:55 UTC

*** Bug 571576 has been marked as a duplicate of this bug. ***

Comment 4 Richard W.M. Jones 2010-03-08 21:47:43 UTC

Looks very similar to bug 516034.  Is this a regression?

Comment 5 Richard W.M. Jones 2010-03-08 21:48:54 UTC

OK I see this is a dupe of bug 566425.
