Description of problem:

I used virt-manager installed on OpenBSD 6.0-beta (x86-64 aka amd64) and connected via qemu+tls to RHEV EL7 host.

When I tried to open SPICE console of a VM, it always fails with:

Error: spice-client-error-quark: USB redirection support not compiled in (0)

OpenBSD does not have usbredir. OpenBSD spice-gtk[1] package is built with '--disable-usbredir' option.

I'm not sure why usbredir is used, the VM does not have 'USB redirection' device at all.

[1] http://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/x11/spice-gtk/Makefile

Version-Release number of selected component (if applicable):
1.4.0

How reproducible:
100%

Steps to Reproduce:
1. have a VM with spice console on a Linux box (I have RHEV EL7 host)
2. have OpenBSD client with virt-manager
3. connect to remote libvirtd and open spice console of a VM

Actual results:
spice console cannot be opened because of usbredir issue

Expected results:
should work as the VM does not have usbredir device thus it should be not
an issue

Additional info:
ping me on irc if needed any help with the client part
