Description

This is caused by the move to a systemd service + the new way services get enabled/disabled by default, which is controlled through a distro-wide policy file now, which AFAIK is part of systemd -> moving to systemd. systemd maintainers, note that the new spice-vdagent systemd service file (and friends) uses hardware activation, so it can safely be enabled by default without impacting non spice vms. What's the precise service name I shell add to the default-to-enable list? (In reply to comment #2) > What's the precise service name I shell add to the default-to-enable list? The service file is: /lib/systemd/system/spice-vdagentd.service Thanks, Hans Doesn't this udev rule handle things?
$ cat /lib/udev/rules.d/70-spice-vdagentd.rules
ACTION=="add", SUBSYSTEM=="virtio-ports", ENV{DEVLINKS}=="/dev/virtio-ports/com.redhat.spice.0", ENV{SYSTEMD_WANTS}="spice-vdagentd.target"
For the QEMU guest agent the rule was slightly different to that:
SUBSYSTEM=="virtio-ports", ATTR{name}=="org.qemu.guest_agent.0", \
TAG+="systemd" ENV{SYSTEMD_WANTS}="qemu-guest-agent.service"

This was done (AFAIK) so that people who have ie bluetooth in their laptop, but never use it and don't want bluez to be running can disable it, etc. See: http://0pointer.de/blog/projects/socket-activation2.html And then the last line of the "Hardware Activation in Detail" paragraph.

Update it with: # su -c 'yum update --enablerepo=updates-testing systemd-195-9.fc18' as soon as you are able to, then reboot. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2012-18708/systemd-195-9.fc18 then log in and leave karma (feedback). systemd-195-8.fc18 has been pushed to the Fedora 18 stable repository. If problems still persist, please make note of it in this bug report. |
