2013-07-19block-migration: efficiently encode zero blocksPeter Lieven
this patch adds a efficient encoding for zero blocks by adding a new flag indicating a block is completely zero. additionally bdrv_write_zeros() is used at the destination to efficiently write these zeroes. depending on the implementation this avoids that the destination target gets fully provisioned.

2013-07-15net: add support of mac-programming over macvtap in QEMU sideAmos Kong
Currently macvtap based macvlan device is working in promiscuous mode, we want to implement mac-programming over macvtap through Libvirt for better performance. Design: QEMU notifies Libvirt when rx-filter config is changed in guest, then Libvirt query the rx-filter information by a monitor command, and sync the change to macvtap device. Related rx-filter config of the nic contains main mac, rx-mode items and vlan table. This patch adds a QMP event to notify management of rx-filter change, and adds a monitor command for management to query rx-filter information. Test: If we repeatedly add/remove vlan, and change macaddr of vlan interfaces in guest by a loop script. Result: The events will flood the QMP client(management), management takes too much resource to process the events. Event_throttle API (set rate to 1 ms) can avoid the events to flood QMP client, but it could cause an unexpected delay (~1ms), guests guests normally expect rx-filter updates immediately. So we use a flag for each nic to avoid events flooding, the event is emitted once until the query command is executed. The flag implementation could not introduce unexpected delay. There maybe exist an uncontrollable delay if we let Libvirt do the real change, guests normally expect rx-filter updates immediately. But it's another separate issue, we can investigate it when the work in Libvirt side is done. Michael S. Tsirkin: tweaked to enable events on start Michael S. Tsirkin: fixed not to crash when no id Michael S.

2013-07-15blockdev: add sync mode to drive-backup QMP commandStefan Hajnoczi
The drive-backup command is similar to the drive-mirror command, except no guest data written after the command executes gets copied. Add a sync mode argument which determines whether the entire disk is copied, just allocated clusters, or only clusters being written to by the guest. Currently only sync mode 'full' is supported - it copies the entire disk. For read-only point-in-time snapshots we may only need sync mode 'none' since the target can be a qcow2 file using the guest's disk as its backing file (no need to copy the entire disk). Finally, sync mode 'top' is useful if we wish to preserve the backing chain. Note that this patch just adds the sync mode argument to drive-backup. It does not implement sync modes 'top' or 'none'. This patch is necessary so we can add a drive-backup HMP command that behaves like the existing drive-mirror HMP command and takes a sync mode.

2013-06-27rdma: introduce capability x-rdma-pin-allMichael R. Hines
This capability allows you to disable dynamic chunk registration for better throughput on high-performance links. For example, using an 8GB RAM virtual machine with all 8GB of memory in active use and the VM itself is completely idle using a 40 gbps infiniband link: 1. x-rdma-pin-all disabled total time: approximately 7.5 seconds @ 9.5 Gbps 2. x-rdma-pin-all enabled total time: approximately 4 seconds @ 26 Gbps These numbers would of course scale up to whatever size virtual machine you have to migrate using RDMA. Enabling this feature does *not* have any measurable affect on migration *downtime*. This is because, without this feature, all of the memory will have already been registered already in advance during the bulk round and does not need to be re-registered during the successive iteration rounds.

2013-05-06target-i386: Add "feature-words" property to X86CPUEduardo Habkost
This property will be useful for libvirt, as libvirt already has logic based on low-level feature bits (not feature names), so it will be really easy to convert the current libvirt logic to something using the "feature-words" property.

This patch adds support for TPM command line options. The command line options supported here are ./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id> -device tpm-tis,tpmdev=<id>,id=<other id> and ./qemu-... -tpmdev help where the latter works similar to -soundhw help and shows a list of available TPM backends (for example 'passthrough'). Using the type parameter, the backend is chosen, i.e., 'passthrough' for the passthrough driver. The interpretation of the other parameters along with determining whether enough parameters were provided is pushed into the backend driver, which needs to implement the interface function 'create' and return a TPMDriverOpts structure if the VM can be started or 'NULL' if not enough or bad parameters were provided. Monitor support for 'info tpm' has been added. It for example prints the following: (qemu) info tpm TPM devices: tpm0: model=tpm-tis \ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Reviewed-by: Corey Bryant <coreyb@linux.vnet.ibm.com> Reviewed-by: Joel Schopp <jschopp@linux.vnet.ibm.com> Message-id: 1361987275-26289-2-git-send-email-stefanb@linux.vnet.ibm.com Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
