[Slackbuilds-users] qemu/spice-gtk and usbredir

Hello,

shouldn't usbredir be listed in REQUIRES of QEMU and spice-gtk?

Because when QEMU is compiled without usbredir present
(autodetected during compilation) virt-install usage will
be problematic or even impossible.


This won't work without usbredir:

~~~~
# virt-install \
  --connect qemu:///system  \
  --name guest1 \
  --cdrom /srv/storage/iso/CentOS-7-x86_64-Minimal-1511.iso \
  --memory 1024 \
  --disk none

ERROR unsupported configuration: USB redirection is not supported by
this version of QEMU
Domain installation does not appear to have been successful.
~~~~



and will work when QEMU was compiled with usbredir present:

~~~~
# virt-install \
  --connect qemu:///system  \
  --name guest1 \
  --cdrom /srv/storage/iso/CentOS-7-x86_64-Minimal-1511.iso \
  --memory 1024 \
  --disk none

Starting install...
Creating domain...
~~~~



Same goes for spice-gtk. When spice-gtk is compiled
without usbredir present then View Manager in virt-manager
won't be able to connect to a VM's screen.
