[Spice-devel] Vdagent not working on xen linux hvm DomUs

[Fabio Fantoni]

I have added vdagent support on libxl for hvm domUs using upstream qemu.
On windows domUs it is working without problems found in over one year 
that I'm using it.

On linux domUs is not working, it seems to be a problem on the kernel 
side and/or linux vdagent services.
The domU parameters are the same on both linux and windows domUs and 
below you can be find some details on dom0 if needed:
http://lists.xen.org/archives/html/xen-devel/2013-10/msg01111.html
On my latest test with Fedora19 domU:
- on install one month ago there was this log: 
/var/log/spice-vdagent.log (nomore now)
> spice-vdagent[1398]: err: Missing virtio device 
> '/dev/virtio-ports/com.redhat.spice.0': No such file or directory
- spice-vdagent package is installed
- /dev/virtio-ports is missed
- lspci shows virtio console with virtio-pci driver in use

Tried to check service:

# systemctl status spice-vdagentd
spice-vdagentd.service - Agent daemon for Spice guests
    Loaded: loaded (/usr/lib/systemd/system/spice-vdagentd.service; enabled)
    Active: inactive (dead)

On /var/log/messages:

But vdagent is still not working.


If you need more details and test tell me and I'll post them.

Thanks for any reply.
