[libvirt-glib 1/3] Add GVirConfigDomainHostdev

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add API to read and write domain/devices/hostdev nodes. This patch only
adds the baseclass and hence is not useful on it's own. A more specific
subclass to represent PCI devices will be added in a following patch.
