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

[Christophe Fergeau]

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
