[Kimchi-devel] [PATCH V7 4/5] write the template OS info to vm metadata

[shaohef at linux.vnet.ibm.com]

From: ShaoHe Feng <shaohef at 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.
