[Spice-devel] [vdagent-linux v2 1/2] vdagent: Silently ignore missing spicevmc device

[Frediano Ziglio]

> 
> On most distros, spice-vdagent will be autostarted as part of the
> startup of the desktop environment session. This is done by
> spice-vdagent.desktop, which has no way of checking if we are in a virt
> environment with the needed devices present.
> 
> Currently, if /dev/virtio-ports/com.redhat.spice.0 is missing, we log an
> error in syslog, and exit with an error exit code. This is too noisy
> when autostarting it on a bare metal machine which have no use for
> spice-vdagent. This reverts 0159111b to get rid of these warnings in the
> session's logs
