2013-03-26migration: do not sent zero pages in bulk stagePeter Lieven1-0/+1
during bulk stage of ram migration if a page is a zero page do not send it at all. the memory at the destination reads as zero anyway. even if there is an madvise with QEMU_MADV_DONTNEED at the target upon receipt of a zero page I have observed that the target starts swapping if the memory is overcommitted. it seems that the pages are dropped asynchronously. this patch also updates QMP to return the number of skipped pages in MigrationStats.

2013-03-12Support for TPM command line optionsStefan Berger1-0/+18
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>

2013-02-06qemu-char: Saner naming of memchar stuff & doc fixesMarkus Armbruster1-26/+29
New device, has never been released, so we can still improve things without worrying about compatibility. Naming is a mess. The code calls the device driver CirMemCharDriver, the public API calls it "memory", "memchardev", or "memchar", and the special commands are named like "memchar-FOO". "memory" is a particularly unfortunate choice, because there's another character device driver called MemoryDriver. Moreover, the device's distinctive property is that it's a ring buffer, not that's in memory. Therefore: * Rename CirMemCharDriver to RingBufCharDriver, and call the thing a "ringbuf" in the API. * Rename QMP and HMP commands from memchar-FOO to ringbuf-FOO. * Rename device parameter from maxcapacity to size (simple words are good for you). * Clearly mark the parameter as optional in documentation. * Fix error reporting so that chardev-add reports to current monitor, not stderr. * Replace cirmem in C identifiers by ringbuf. * Rework documentation. Document the impact of our crappy UTF-8 handling on reading. * QMP examples that even work. I could split this up into multiple commits, but they'd change the same documentation lines multiple times.

Command memchar-write takes data and size parameter. Begs the question what happens when data doesn't match size. With format base64, qmp_memchar_write() copies the full data argument, regardless of size argument. With format utf8, qmp_memchar_write() copies size bytes from data, happily reading beyond data. Copies crap from the heap or even crashes. Drop the size parameter, and always copy the full data argument.

2012-10-24mirror: add support for on-source-error/on-target-errorPaolo Bonzini1-1/+7
Error management is important for mirroring; otherwise, an error on the target (even something as "innocent" as ENOSPC) requires to start again with a full copy. Similar to on_read_error/on_write_error, two separate knobs are provided for on_source_error (reads) and on_target_error (writes). The default is 'report' for both. The 'ignore' policy will leave the sector dirty, so that it will be retried later. Thus, it will not cause corruption.

2012-08-15qapi: Introduce add-fd, remove-fd, query-fdsetsCorey Bryant1-0/+122
This patch adds support that enables passing of file descriptors to the QEMU monitor where they will be stored in specified file descriptor sets. A file descriptor set can be used by a client like libvirt to store file descriptors for the same file. This allows the client to open a file with different access modes (O_RDWR, O_WRONLY, O_RDONLY) and add/remove the passed fds to/from an fd set as needed. This will allow QEMU to (in a later patch in this series) "open" and "reopen" the same file by dup()ing the fd in the fd set that corresponds to the file, where the fd has the matching access mode flag that QEMU requests. The new QMP commands are: add-fd: Add a file descriptor to an fd set remove-fd: Remove a file descriptor from an fd set query-fdsets: Return information describing all fd sets Note: These commands are not compatible with the existing getfd and closefd QMP commands.

IMPORTANT: this BREAKS QMP's compatibility for the error response. This commit changes QMP's wire protocol to make use of the simpler error format introduced by previous commits. There are two important (and mostly incompatible) changes: 1. Almost all error classes have been replaced by GenericError. The only classes that are still supported for compatibility with libvirt are: CommandNotFound, DeviceNotActive, KVMMissingCap, DeviceNotFound and MigrationExpected 2. The 'data' field of the error dictionary is gone As an example, an error response like: { "error": { "class": "DeviceNotRemovable", "data": { "device": "virtio0" }, "desc": "Device 'virtio0' is not removable" } } Will now be emitted as: { "error": { "class": "GenericError", "desc": "Device 'virtio0' is not removable" } } Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com>
