This patch depends on "[PATCH V1 0/6] VM supports interfaces"
1. get all vms:
$ curl -u <user> -H 'Accept: application/json' -H 'Content-type:
application/json' http://localhost:8000/vms
2. get all networks:
$ curl -u <user> -H 'Accept: application/json' -H 'Content-type:
application/json' http://localhost:8000/networks
3. get all ifaces of a vm
$ curl -u <user> -H 'Accept: application/json' -H 'Content-type:
application/json' http://localhost:8000/vms/test-vm-0/ifaces/
[
{
"mac":"52:54:00:00:00:01",
"model":"virtio",
"type":"network",
"network":"default"
}
]
4. attach a new iface to vm
$ curl -u <user> -H 'Accept: application/json' -H 'Content-type:
application/json' http://localhost:8000/vms/test-vm-8/ifaces -X POST -d '
{
"type":"network",
"network":"test-network-0"
}
'
{
"mac":"52:54:00:00:00:0d",
"model":"virtio",
"type":"network",
"network":"test-network-0"
}
5. detach a iface from vm
$ curl -u <user> -H 'Accept: application/json' -H 'Content-type:
application/json' http://localhost:8000/vms/test-vm-8/ifaces/52:54:00:00:00:0d -X

Any reason not using lxml.builder ?
seems a difference.
objectify support python type date. builder does not support python type
date.
In [74]: from lxml.builder import E
In [75]: root = E.root(
E.a("5"),
E.b("6.1"),
E.c("True"),
E.d("how", tell="me")
)
In [76]: print(etree.tostring(root, pretty_print=True))
<root>
<a>5</a>
<b>6.1</b>
<c>True</c>
<d tell="me">how</d>
</root>
In [79]: from lxml.objectify import E
In [80]: root = E.root(
E.a(5),
E.b(6.1),
E.c(True),
E.d("how", tell="me")
)
In [81]: print(etree.tostring(root, pretty_print=True))
<root xmlns:py="http://codespeak.net/lxml/objectify/pytype"

I think we need affect both the running guest state and persist config.
