Description of problem:
On a fresh Fedora 11 install (updated April 2nd 4:30pm EST).

When trying to create a VM using virt-manager that uses an ISO file as the media source, it fails with:

libvirtError: internal error unable to start guest: qemu: could not open disk image /root/RHEL5.3-Server-i386-DVD.iso


Version-Release number of selected component (if applicable):
virt-manager-0.7.0-2.fc11.i586

How reproducible:
Every single time

Steps to Reproduce:
1. Start virt-manager and hit the "new" button to create a new VM, give it a name, and select "Local install media"...hit "Forward".
2. Use ISO image, and point to the path of an ISO on the filesystem, OS Type: Linux, Version: Red Hat Enterprise Linux 5 ... hit "Forward"
3. Memory: 256, CPUs: 1 ... hit "Forward"
4. Check "Enable storage for this virtual machine", Create a 4GB disk image, and check "Allocate entire disk now" ... hit "Forward"
5. At the final screen, hit "Finish"
6. Wait a few moments, and it will fail

Actual results:

Unable to complete install '<class 'libvirt.libvirtError'> internal error unable to start guest: qemu: could not open disk image /root/RHEL5.3-Server-i386-DVD.iso

Expected results:
A new window showing the Bochs BIOS screen, followed by the CDROMs boot screen.

Additional info:

If you avoid 'virt-manager' and work with 'qemu-kvm' directly, it launches the VM as expected when you run the following:

qemu-img create -f qcow rhel5.3.img 4G
qemu-kvm -boot d -cdrom /root/RHEL5.3-Server-i386-DVD.iso -hda ./rhel5.3.img
