Just install RHEL 6 x86_64, subscribe to RHN for rhevm.sddlab.com and with RHEVM 3.1 and JBoss 6 channel.
After successfully yum update,reboot and try to install rhevm package with
# yum -y install rhevm
error with broken dependency

Error: Package: rhevm-3.1.0-32.el6ev.noarch (rhel-x86_64-server-6-rhevm-3.1)
           Requires: virtio-win
 You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodiges

Try with --skip-broken options, but package still not download and installed

Please help to workaround this issue
