[libvirt] [PATCH RFC 00/10] API && XML to control virtual link state of guest NICs

[Peter Krempa]

Hypervisors provide means for controling link state of virtual NICs. Ability
to control this can be usefully used for various aplications. These patches
add (or propose) an API for controling link states of these nics.

API functions added:
-----------------------------------------------------------------------
int virDomainInterfaceLinkSetState(virDomainPtr dom,
                                   const char *path,
                                   unsigned int state,
                                   unsigned int flags);
This function sets link state for a NIC. A NIC is identified by the domain and
path (which is MAC address of the NIC (in a string representation)).

States are represented by the virInterfaceLinkStates enum.

Flags determine manipulation impact of the command (live/persistent).


int virDomainInterfaceLinkGetState(virDomainPtr dom,
                                   const char *path,
                                   unsigned int flags);
This function requests the interface state and returns it
as the return value.

Peter Krempa (10):
