| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make monitor command 'dump-guest-memory' be able to dump in kdump-compressed format. The command's usage: dump [-p] protocol [begin] [length] [format] 'format' is used to specified the format of vmcore and can be: 1. 'elf': ELF format, without compression 2. 'kdump-zlib': kdump-compressed format, with zlib-compressed 3. 'kdump-lzo': kdump-compressed format, with lzo-compressed 4. 'kdump-snappy': kdump-compressed format, with snappy-compressed Without 'format' being set, it is same as 'elf'. And if non-elf format is specified, paging and filter is not allowed. Note: 1. The kdump-compressed format is readable only with the crash utility and makedumpfile, and it can be smaller than the ELF format because of the compression support. 2. The kdump-compressed format is the 6th edition.

* block: add native support for NFSPeter Lieven2014-02-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds native support for accessing images on NFS shares without the requirement to actually mount the entire NFS share on the host. NFS Images can simply be specified by an url of the form: nfs://<host>/<export>/<filename>[?param=value[&param2=value2[&...]]] For example: qemu-img create -f qcow2 nfs://10.0.0.1/qemu-images/test.qcow2 You need LibNFS from Ronnie Sahlberg available at: git://github.com/sahlberg/libnfs.git for this to work. During configure it is automatically probed for libnfs and support is enabled on-the-fly. You can forbid or enforce libnfs support with --disable-libnfs or --enable-libnfs respectively. Due to NFS restrictions you might need to execute your binaries as root, allow them to open priviledged ports (<1024) or specify insecure option on the NFS server. For additional information on ROOT vs. non-ROOT operation and URL format + parameters see: https://raw.github.com/sahlberg/libnfs/master/README Supported by qemu are the uid, gid and tcp-syncnt URL parameters. LibNFS currently support NFS version 3 only. Signed-off-by: Peter Lieven <pl@kamp.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

| | | | | | | | | | | | | | | | This updates the documentation for commiting snapshot images. Specifically, this highlights what happens when the base image is either smaller or larger than the snapshot image being committed. In the case of the base image being smaller, it is resized to the larger size of the snapshot image. In the case of the base image being larger, it is not resized automatically, but once the commit has completed it is safe for the user to truncate the base image.

Luiz does not like in 1 the fact that 2 fields are optional but one of them must be specified leading to an abuse of the QMP semantic. Kevin argumented that 2 what a clear abuse of the device field and would not be practical when reading fast some log file because the user would read "device" and think that a device is manipulated when it's in fact a node name. Documentation of 1 make it pretty clear what to do for the user. Kevin argued that all bs are node including devices ones so 2 does not make sense. Kevin also argued that rewriting the QMP block interface would not make disapear the current one. Kevin pushed the argument that making the QAPI generator compatible with the semantic of the operation would need a rewrite that no one has done yet. A vote has been done on the list to elect the version to use and 1 won. For reference the complete thread is: "[Qemu-devel] [PATCH V4 4/7] qmp: Allow to change password on names block driver states."

* net: Adding netmap network backendVincenzo Maffione2013-12-091-1/+23
| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for a network backend based on netmap. netmap is a framework for high speed packet I/O. You can use it to build extremely fast traffic generators, monitors, software switches or network middleboxes. Its companion software switch VALE lets you interconnect virtual machines. netmap and VALE are implemented as a non-intrusive kernel module, support NICs from multiple vendors, are part of standard FreeBSD distributions and available in source format for Linux too. To compile QEMU with netmap support, use the following configure options: ./configure [...] --enable-netmap --extra-cflags=-I/path/to/netmap/sys where "/path/to/netmap" contains the netmap source code, available at http://info.iet.unipi.it/~luigi/netmap/ The same webpage contains more information about the netmap project (together with papers and presentations).

* Revert "chardev: Make the name of memory device consistent"Markus Armbruster2013-07-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 6a85e60cb994bd95d1537aafbff65816f3de4637. Commit 51767e7 "qemu-char: Add new char backend CirMemCharDriver" introduced a memory ring buffer character device driver named "memory". Commit 3949e59 "qemu-char: Saner naming of memchar stuff & doc fixes" changed the driver name to "ringbuf", along with a whole bunch of other names, with the following rationale: 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. This is what we released in 1.4.0. Unfortunately, the rename missed a critical instance of "memory": the actual driver name. Thus, the new device could be used only by an entirely undocumented name. The documented name did not work. Bummer. Commit 6a85e60 fixes this by changing the documentation to match the code. It also changes some, but not all related occurences of "ringbuf" to "memory". Left alone are identifiers in C code, HMP and QMP commands. The latter are external interface, so they can't be changed. The result is an inconsistent mess. Moreover, "memory" is a rotten name. The device's distinctive property is that it's a ring buffer, not that's in memory. User's don't care whether it's in RAM, flash, or carved into chocolate tablets by Oompa Loompas. Revert the commit. Next commit will fix just the bug.

| | | | | | | | | | | | 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.

| * net: add support of mac-programming over macvtap in QEMU sideAmos Kong2013-07-151-0/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
