[libvirt] [PATCH v3 0/4] libxl: channels support

[Joao Martins]

Hey,

This v3 from channel series with latest comments addressed. Difference to
qemu driver would be only the autogenerated path being slightly different.

Channels have been on xen toolstack since Xen 4.5 and this small series
adds support for it, including xenconfig conversion and appropriate tests.
After this series it's possible to do this:
(assuming correct configuration of qemu agent in the guest)

 $ cat domain.xml | grep -a1 channel | head -n 5 | tail -n 4
 <channel type='unix'>
   <source mode='bind' path='/tmp/channel'/>
   <target type='xen' name='org.qemu.guest_agent.0'/>
 </channel>

 $ virsh create domain.xml
 $ echo '{"execute":"guest-network-get-interfaces"}' | socat
 stdio,ignoreeof  unix-connect:/tmp/channel

 {"execute":"guest-network-get-interfaces"}
 {"return": [{"name": "lo", "ip-addresses": [{"ip-address-type": "ipv4",
 "ip-address": "127.0.0.1", "prefix": 8}, {"ip-address-type": "ipv6",
 "ip-address": "::1", "prefix": 128}], "hardware-address":
 "00:00:00:00:00:00"}, {"name": "eth0", "ip-addresses":
 [{"ip-address-type": "ipv4", "ip-address": "10.100.0.6", "prefix": 24},
 {"ip-address-type": "ipv6", "ip-address": "fe80::216:3eff:fe40:88eb",
 "prefix": 64}], "hardware-address": "00:16:3e:40:88:eb"}, {"name":
 "sit0"}]}

Thanks,
Joao
