[Spice-devel] spice-vdagent start failed

[Dunrong Huang]

hi,

It seems that your Host os is gentoo, and guest os is windows xp.

QEMU running on your host simulates the device for guest os, and your
host do not know nothing of the device.
So guest is responsible for installing device driver, runing agent
application for communication with device and QEMU.

The virtual serial device only exists in guest os(for linux guest, the
path is /dev/virtio-ports/com.redhat.spice.0),
so you wont get /dev/virtio-ports/com.redhat.spice.0 in your host.
Similarly, Only the guest os has /etc/init.d/spice-vdagent
and can run it.

In your case, you shoud download and install window drivers in your windows XP.
Please refer: http://spice-space.org/download.html  // Guest -> Windows binaries
