Hello,
I am trying to develop custom xen vif- and network- scripts and can''t
figure out how to passing parameters. When creating a domain, I would
like to be able to specify two additional parameters for each vif and
get access to them via from my custom vif-script.
I have done some research and found I can easiliy extend the list of
parameters accepted by ''xm create'' command by editing
/usr/lib/xen-4.0/lib/python/xen/xm/create.py. It all works just fine in
the dry mode, I see the parameters and their value dumped on the output.
But when the domain gets created these values don''t see to be retained
in the config, I see no traces of them in the output of ''xm list
VMID''.
I have also attempted to edit vif_params in main.py to add same two
parameters to ''network-attach'' command handler. It has not
helped, the
parameter don''t seem to make it into the config nor xenstore anyway.
I could use an advice how this can be implemented properly. I thinking
about customizing create.py further, to store values I need to persist
in xenstore under /vm/UUID/device/vif/NNN/. Just wondering if I am
overlooking some more elegant solution. Any advise is appreciated.
PS. I use xm toolstack on Xen 4.0.1 on Debian.
Best regards,
Alex
