[libvirt] [PATCHv3 0/3] S390: Finish support for native CCW bus
Originally, QEMU did not implement a native I/O bus for s390. The initial implementation had a machine type 's390-virtio' featuring a fully paravirtualized I/O system with an artificial bus type 'virtio-s390'. This bus had a number of short-comings, like the need for a non-standard device discovery mechanism, a limited number of devices, limited hotplugging capabilites and the lack of persistent device addresses. To resolve these issues a new machine type 's390-ccw-virtio' has been recently added to QEMU which implementa the native s390 CCW I/O bus. Guests with arch='s390x' and machine='s390-ccw-virtio' can now be defined with up to 262144 virtio devices. This series adds the support for the s390-ccw-virtio machine type and the CCW bus to libvirt. V2 Changes - use an attribute triple cssid, ssid, schid instead of devno to better represent the libvirt CCW address structure - rebase to current upstream, mainly address qemuCapsXXX rename V3 Changes - skip already acked patches 1/5 and 2/5 - revert machine-based capabilities - use machine definition from domain object J.B.

This commit adds the QEMU driver support for CCW addresses. The current QEMU only allows virtio devices to be attached to the CCW bus. We named the new capability indicating that support QEMU_CAPS_VIRTIO_CCW accordingly. The fact that CCW devices can only be assigned to domains with a machine type of s390-ccw-virtio requires a few extra checks for machine type in qemu_command.c on top of querying QEMU_CAPS_VIRTIO_{CCW|S390}. The majority of the new functions deals with CCW address generation and management.

From: "J.B. Joret" <jb@linux.vnet.ibm.com> We didn't yet expose the virtio device attach and detach functionality for s390 domains as the device hotplug was very limited with the old virtio-s390 bus. With the CCW bus there's full hotplug support for virtio devices in QEMU, so we are adding this to libvirt too. Since the virtio hotplug isn't limited to PCI anymore, we change the function names from xxxPCIyyy to xxxVirtioyyy, where we handle all three virtio bus types. Signed-off-by: J.B.

volunteers for a review, any? Don't feel intimidated by the patch sizes, as the patches are rather mundane: 1/3 is mainly new code for persisting the ccw bus addresses. 2/3 is mainly refactoring to allow hotplugging of pci and other (ccw) virtio devices. 3/3 is the usual test stuff.
