Re: [libvirt] [PATCH 1/5] character device: Allow character devices to have different target types

Currently a character device's target (it's interface in the guest) has only a single property: port. This patch is in preparation for adding targets which require other properties. Target properties are moved into a union in virDomainChrDef, and a targetType field is added to identify which union member should be used. All current code which touches a virDomainChrDef is updated both to use the new union field, and to populate targetType if necessary.
