[Qemu-devel] [PATCH 2/3] ui: spice: Exit if gl=on EGL init fails

[Cole Robinson <crobinso@redhat.com>]

The user explicitly requested spice GL, so if we know it isn't
going to work we should exit

Signed-off-by: Cole Robinson <crobinso@redhat.com>

For example, trying to use spice GL with libvirt qemu:///system will
fail here, since the the VM will lack permissions to access
/dev/dir/renderD*
