2014-06-19vhost-net: vhost-user feature bits supportNikolay Nikolaev
Handle the feature bits negotiation when using vhost-user. Allow the underlying implementation to have a finer control over all the bits except the VIRTIO_NET_F_MAC.

2014-06-19Add vhost-user as a vhost backend.Nikolay Nikolaev
The initialization takes a chardev backed by a unix domain socket. It should implement qemu_fe_set_msgfds in order to be able to pass file descriptors to the remote process. Each ioctl request of vhost-kernel has a vhost-user message equivalent, which is sent over the control socket. The general approach is to copy the data from the supplied argument pointer to a designated field in the message. If a file descriptor is to be passed it will be placed in the fds array for inclusion in the sendmsg control header. VHOST_SET_MEM_TABLE ignores the supplied vhost_memory structure and scans the global ram_list for ram blocks with a valid fd field set. This would be set when the '-object memory-file' option with share=on property is used.

2014-06-19Add vhost_ops to vhost_dev struct and replace all relevant ioctlsNikolay Nikolaev
Decouple vhost from the Linux kernel by introducing vhost_ops. The intention is to provide different backends - a 'kernel' backend based on the ioctl interface, and an 'user' backend based on a UNIX domain socket and shared memory interface.

2014-06-19vhost_net_init will use VhostNetOptions to get all its argumentsNikolay Nikolaev
vhost_dev_init will replace devfd and devpath with a single opaque argument. This is initialised with a file descriptor. When TAP is used (through vhost_net), open /dev/vhost-net and pass the fd as an opaque parameter in VhostNetOptions. The same applies to vhost-scsi - open /dev/vhost-scsi and pass the fd.

2014-06-19virtio-net: announce self by guestJason Wang
It's hard to track all mac addresses and their configurations (e.g vlan or ipv6) in qemu. Without this information, it's impossible to build proper garp packet after migration. The only possible solution to this is let guest (who knows all configurations) to do this. So, this patch introduces a new readonly config status bit of virtio-net, VIRTIO_NET_S_ANNOUNCE which is used to notify guest to announce presence of its link through config update interrupt.When guest has done the announcement, it should ack the notification through VIRTIO_NET_CTRL_ANNOUNCE_ACK cmd. This feature is negotiated by a new feature bit VIRTIO_NET_F_ANNOUNCE (which has already been supported by Linux guest). During load, a counter of announcing rounds is set so that after the vm is running it can trigger rounds of config interrupts to notify the guest to build and send the correct garps.

2014-06-16spapr_pci: Advertise MSI quotaBadari Pulavarty
Hotplug of multiple disks fails due to MSI vector quota check. Number of MSI vectors default to 8 allowing only 4 devices. This happens on RHEL6.5 guest. RHEL7 and SLES11 guests fallback to INTX. One way to workaround the issue is to increase total MSIs, so that MSI quota check allows us to hotplug multiple disks. This sets the quota to the maximum number of interupts XICS has which is 1024 now (XICS_IRQS). This moves XICS_IRQS from spapr.c to xics.h for wider visibility.

PR KVM supports an ePAPR compliant hypercall interface in parallel to the normal sPAPR one. Expose the ePAPR /hypervisor node and properties to the guest so it can use it. This enables magic page sharing on PR KVM with -M pseries. However we had a few nasty bugs in the magic page implementation on vcpus newer than 970 (p7, p8) that KVM now has workarounds for. It indicates that it does have these workarounds through the PPC_FIXUP_HCALL capability. To not expose broken guest kernels to issues on host kernels that don't have the fixups in place, we don't expose working hypercall instructions when the fixups are not available so that the guest can never active the magic page.

2014-06-16hw/pci-host/ppce500: Fix typo in vmstate definitionPeter Maydell
Fix a typo in the ppce500_pci vmstate definition which meant that we were migrating the struct pci_inbound using the vmstate for pci_outbound. Fortunately the two structures have exactly the same format at the moment (four uint32_ts) so this was harmless, and we can correcting the typo without a migration compatibility break because the vmstate name doesn't go out on the wire.
