[PATCH V10 7/7] write the template OS info to vm metadata
by shaohef＠linux.vnet.ibm.com
From: ShaoHe Feng <shaohef(a)linux.vnet.ibm.com>
Then kimchi can choose the divice mode depend on these info.
Note, the info is the initial OS when install OS on a blank guest.
OS may change after the install.
So other device should still keep their model info in the vm metadata.

[PATCH V10 3/7] Add two function to set and get domain xml metadata
by shaohef＠linux.vnet.ibm.com
From: ShaoHe Feng <shaohef(a)linux.vnet.ibm.com>
Libvirt support two API to set and get domain xml metadata.
These two function wrap them.
Put them in model/utils.py, so vm_storage and vm_iface can make use of
them.
For set domain xml metadata, we set live and config xml by default.
For get domain xml metadata, we get the current xml by default.
