Re: [Qemu-discuss] [problem] QEMU-GA & Windows 10

[Frank Sfalanga Jr .]

Hi Dominique,

Thank you for your help.  I have added the requested XML and created the
missing directory, verifying the permissions and ownership exist for
libvirt-qemu:kvm as all the other directories do.  This should allow
libvirt to have write permissions, no?

Here is the error I'm receiving when trying to start the VM (it looks
like a permission issue):

------------------------------------------------------

-------------------------------------------------------


Here is the ownership and file permissions for every directory off
of /var/lib/libvirt.  I had to create the channel/target/ directory and
sub

------------------------------------------------------

address@hidden:/# tree -dugp /var/lib/libvirt

----------------------------------------------------

... did I miss something?

Thank you in advance.

Kind regards,

#Add in the xml before the closing tag </devices>:
<channel type='unix'>
   <target type='virtio' name='org.qemu.quest_agent.0' state='connected' />
</channel>
After saving, look into the xml again. If all is right, libvirt added some 
extra lines. One of the lines
has a path (ex. 
path='/var/lib/libvirt/qemu/channel/target/domain-XXXXX/org.qemu.guest_agent.0').
Check if the path (until the folder domain-XXXXX) exists and libvirt can write 
to it. If not, create it
yourselves and apply the correct rights.
Also look at the 'address' part. The combination type+controller+bus+port 
should be unique in
your xml. If not, change the port to a free port of that bus.

Make shure you have shutdown the guest.
Start the guest again.
If all is right, the guest agent should start on startup.

Note: it's not necessary  QEMU GUEST AGENT VSS PROVIDER is started.
The guest agent will start the VSS Provider if needed.
It can't hurt neither, it will stop automatically when it wants to...

Hope this helps...
