2015-03-19virtio: serial: expose a 'guest_writable' callback for usersAmit Shah
Users of virtio-serial may want to know when a port becomes writable. A port can stop accepting writes if the guest port is open but not being read from. In this case, data gets queued up in the virtqueue, and after the vq is full, writes to the port do not succeed. When the guest reads off a vq element, and adds a new one for the host to put data in, we can tell users the port is available for more writes, via the new ->guest_writable() callback.

2015-03-17usb/dev-storage: Fix QMP device_add missing encryption key failureMarkus Armbruster
When the image is encrypted, QMP device_add creates the device, defers actually attaching it to when the key becomes available, then returns an error. This is wrong. device_add must either create the device and succeed, or do nothing and fail. The bug is in usb_msd_realize_storage(). It posts an error with qerror_report_err(), and returns success. Device realization relies on the return value, and completes. The QMP monitor, however, relies on the posted error, and sends it in an error reply. Reproducer: $ qemu-system-x86_64 -nodefaults -display none -usb -qmp stdio -drive if=none,id=foo,file=geheim.qcow2 {"QMP": {"version": {"qemu": {"micro": 50, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}} { "execute": "qmp_capabilities" } {"return": {}} { "execute": "device_add", "arguments": { "driver": "usb-storage", "id": "bar", "drive": "foo" } } {"error": {"class": "DeviceEncrypted", "desc": "'foo' (geheim.qcow2) is encrypted"}} Even though we got an error back, the device got created just fine.

2015-03-16migration: Allow to suppress vmdesc submissionAlexander Graf
We now always send a JSON blob describing the migration file format as part of the migration stream. However, some tools built around QEMU have proven to stumble over this. This patch gives the user the chance to disable said self-describing part of the migration stream. To disable vmdesc submission, just add -machine suppress-vmdesc=on to your QEMU command line.

2015-03-16hw/intc/arm_gic: Initialize the vgic in the realize functionEric Auger
This patch forces vgic initialization in the vgic realize function. It uses a new group/attribute that allows such operation: KVM_DEV_ARM_VGIC_GRP_CTRL/KVM_DEV_ARM_VGIC_CTRL_INIT This earlier initialization allows, for example, to setup VFIO signaling and irqfd after vgic initialization, on a reset notifier.

2015-03-16s390x: CPACF: Handle key wrap machine optionsTony Krowiak
Check for the aes_key_wrap and dea_key_wrap machine options and set the appropriate KVM device attribute(s) to tell the kernel to enable or disable the AES/DEA protected key functions for the guest domain. This patch introduces two new machine options for indicating the state of AES/DEA key wrapping functions. This controls whether the guest will have access to the AES/DEA crypto functions. aes_key_wrap="on | off" is changed to aes-key-wrap="on | off" dea_key_wrap="on | off" is changed to dea-key-wrap="on | off" Check for the aes-key-wrap and dea-key-wrap machine options and set the appropriate KVM device attribute(s) to tell the kernel to enable or disable the AES/DEA protected key functions for the guest domain.

2015-03-16s390x/kvm: Guest Migration TOD clock synchronizationJason J. Herne
Synchronizes the guest TOD clock across a migration by sending the guest TOD clock value to the destination system. If the guest TOD clock is not preserved across a migration then the guest's view of time will snap backwards if the destination host clock is behind the source host clock. This will cause the guest to hang immediately upon resuming on the destination system. Reviewed-by: David Hildenbrand <dahi@linux.vnet.ibm.com> Signed-off-by: Jason J.

2015-03-16s390x: Replace unchecked qdev_init() by qdev_init_nofail()Markus Armbruster
s390_flic_init() is a helper to create and realize either "s390-flic-kvm" or "s390-flic-qemu". When qdev_init() fails, it complains to stderr and succeeds. Except it can't actually fail, because the "s390-flic-qemu" is a dummy without a realize method, and "s390-flic-kvm"'s realize can't fail, even when the kernel device is really unavailable. Odd. Replace qdev_init() by qdev_init_nofail() to make "can't fail" locally obvious, and get rid of the unreachable error reporting.
