[Kimchi-devel] [PATCH V2] [Kimchi 1/2] Updated code to support VM ifaces on s390x/s390 architecture.

archus at linux.vnet.ibm.com
Thu Sep 1 15:56:03 UTC 2016
From: Archana Singh <archus at linux.vnet.ibm.com>
1) Code ensures that additional type macvtap, ovs are only
supported on s390x/s390 architecture. On other arch it throws
Error for these two type.
2) Code ensures that source is provided for type macvtap, ovs
and only applicable for s390x/s390 architecture.
3) Code to create/get VM ifaces for source of type macvtap or ovs on
s390x/s390 architecture.
