Hi Ravi, We did this as part of PoC few months back.
Daniel can give us more comments on this as he is the lead for Libvirt support in Nova.

Now all set to collaborate the BP with the use case. Thanks, -Ravi.

To start with I experimented on existing Wangpan's added feature on hw_qemu_guest agent. I am preparing to propose a blueprint to modify it for generic use and open to collaborate. I could bring up VM with generic source path(say /tmp/appliance_port) and target name(appliance_port). But I see qemu listening on the unix socket in host as soon as I start the VM. If we want to have our server program on host listening, that should not happen. How do I overcome that? Thanks, -Ravi.

So I think the opinion of Daniel will be very useful. 2013-09-25 ________________________________ Wangpan ________________________________ 发件人：balaji patnala <patnala...@gmail.com<mailto:patnala...@gmail.com>> 发送时间：2013-09-25 22<tel:2013-09-25%C2%A022>:36 主题：Re: [openstack-dev] [Nova] [Libvirt] Virtio-Serial support for Nova libvirt driver 收件人："OpenStack Development Mailing List"<openstack-dev@lists.openstack.org<mailto:openstack-dev@lists.openstack.org>> 抄送： Hi Haomai, Thanks for your interest on this. The code check-ins done against the below bp are more specific to Qemu Guest Agent. https://blueprints.launchpad.net/nova/+spec/qemu-guest-agent-support Our requirement is to enable Virtio-Serial Interface to the applications running in VM. Do you have the same requirement? We will share the draft BP on this. Any comments on this approach will be helpful.

Great! We have common interest and I hope we can promote it for IceHouse. BTW, do you have a initial plan or description about it. And I think this bp may invoke. https://blueprints.launchpad.net/nova/+spec/qemu-guest-agent-support > > Regards, > Balaji.P > > > _______________________________________________ > OpenStack-dev mailing list > OpenStack-dev@lists.openstack.org<mailto:OpenStack-dev@lists.openstack.org> > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev Best regards, Haomai Wang, UnitedStack Inc. _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org<mailto:OpenStack-dev@lists.openstack.org> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org<mailto:OpenStack-dev@lists.openstack.org> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev -- Ravi -- Ravi
