[PATCH 12/13] Move and rename qemuDomainAssignPCIAddresses et al

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

 



qemuDomainPCIControllerSetDefaultModelName is renamed to
qemuDomainAssignPCIAddresses is renamed to virDomainAssignPCIAddresses

Both are moved from qemu_domain_addr.c to domain_addr.c

All these functions are being moved because they don't depend on
qemu, so they have the potential to be reused for more hypervisors.
