KVM-Qemu could not open disk image

[Aaron Siegel]

Hello 

I have installed an evaluation of RHEL 7.  I receive an error when
trying to install a virtual machine using virt-manager. I receive the
following errow when KVM is initiated:

Unable to complete install: 'internal error: process exited while
connecting to monitor: qemu-kvm: -drive
file=/var/lib/libvirt/images/test.img,if=none,id=drive-ide0-0-0,format=raw,cache=none: could not open disk image /var/lib/libvirt/images/test.img: Could not open file: Invalid argument
'

I have edited the user and group in the /etc/libvirt/qemu.conf file to
different and chown the directory /var/lib/libvirt/qemu. I have also
allowed rw to everyone to the entire /var/lib/libvirt directory. Nothing
is working.
