Our command line interface is really quite overcrowded, we should avoid duplicated options that do the same thing in just a slightly different way.

2018-11-12bt: Mark the bluetooth subsystem as deprecatedThomas Huth1-0/+4
It has been unmaintained since years, and there were only trivial or tree-wide changes to the related files since many years, so the code is likely very bitrotten and broken. For example the following segfaults as soon as as you press a key: qemu-system-x86_64 -usb -device usb-bt-dongle -bt hci -bt device:keyboard Since we are not aware of anybody using bluetooth with the current version of QEMU, let's mark the subsystem as deprecated, with a special request for the users to write to the qemu-devel mailing list in case they still use it (so we could revert the deprecation status in that case).

2018-10-01qcow2: Increase the default upper limit on the L2 cache sizeLeonid Bloch1-3/+3
The upper limit on the L2 cache size is increased from 1 MB to 32 MB on Linux platforms, and to 8 MB on other platforms (this difference is caused by the ability to set intervals for cache cleaning on Linux platforms only). This is done in order to allow default full coverage with the L2 cache for images of up to 256 GB in size (was 8 GB). Note, that only the needed amount to cover the full image is allocated. The value which is changed here is just the upper limit on the L2 cache size, beyond which it will not grow, even if the size of the image will require it to.

2018-10-01qcow2: Assign the L2 cache relatively to the image sizeLeonid Bloch1-3/+3
Sufficient L2 cache can noticeably improve the performance when using large images with frequent I/O. Previously, unless 'cache-size' was specified and was large enough, the L2 cache was set to a certain size without taking the virtual image size into account. Now, the L2 cache assignment is aware of the virtual size of the image, and will cover the entire image, unless the cache size needed for that is larger than a certain maximum. This maximum is set to 1 MB by default (enough to cover an 8 GB image with the default cluster size) but can be increased or decreased using the 'l2-cache-size' option. This option was previously documented as the *maximum* L2 cache size, and this patch makes it behave as such, instead of as a constant size. Also, the existing option 'cache-size' can limit the sum of both L2 and refcount caches, as previously.

2018-08-10hostmem-file: add the 'pmem' optionJunyan He1-0/+7
When QEMU emulates vNVDIMM labels and migrates vNVDIMM devices, it needs to know whether the backend storage is a real persistent memory, in order to decide whether special operations should be performed to ensure the data persistence. This boolean option 'pmem' allows users to specify whether the backend storage of memory-backend-file is a real persistent memory. If 'pmem=on', QEMU will set the flag RAM_PMEM in the RAM block of the corresponding memory region. If 'pmem' is set while lack of libpmem support, a error is generated.

2018-07-16cli qmp: Mark --preconfig, exit-preconfig experimentalMarkus Armbruster1-4/+5
Committing to the current --preconfig / exit-preconfig interface before it has seen any use is premature. Mark both as experimental, the former in documentation, the latter by renaming it to x-exit-preconfig. See the previous commit for more detailed rationale.

2018-07-03crypto: Implement TLS Pre-Shared Keys (PSK).Richard W.M. Jones1-0/+24
Pre-Shared Keys (PSK) is a simpler mechanism for enabling TLS connections than using certificates. It requires only a simple secret key: $ mkdir -m 0700 /tmp/keys $ psktool -u rjones -p /tmp/keys/keys.psk $ cat /tmp/keys/keys.psk rjones:d543770c15ad93d76443fb56f501a31969235f47e999720ae8d2336f6a13fcbc The key can be secretly shared between clients and servers. Clients must specify the directory containing the "keys.psk" file and a username (defaults to "qemu"). Servers must specify only the directory. Example NBD client: $ qemu-img info \ --object tls-creds-psk,id=tls0,dir=/tmp/keys,username=rjones,endpoint=client \ --image-opts \ file.driver=nbd,file.host=localhost,file.port=10809,file.tls-creds=tls0,file.export=/ Example NBD server using qemu-nbd: $ qemu-nbd -t -x / \ --object tls-creds-psk,id=tls0,endpoint=server,dir=/tmp/keys \ --tls-creds tls0 \ image.qcow2 Example NBD server using nbdkit: $ nbdkit -n -e / -fv \ --tls=on --tls-psk=/tmp/keys/keys.psk \ file file=disk.img Signed-off-by: Richard W.M.

2018-06-28kvm: support -overcommit cpu-pm=on|offMichael S. Tsirkin1-0/+24
With this flag, kvm allows guest to control host CPU power state. This increases latency for other processes using same host CPU in an unpredictable way, but if decreases idle entry/exit times for the running VCPU, so to use it QEMU needs a hint about whether host CPU is overcommitted, hence the flag name. Follow-up patches will expose this capability to guest (using mwait leaf). Based on a patch by Wanpeng Li <kernellwp@gmail.com> . Signed-off-by: Michael S.

2018-06-28Deprecate the -enable-hax optionThomas Huth1-1/+1
We currently have got three ways of turning on the HAX accelerator: "-machine accel=hax", "-accel hax" and "-enable-hax". That's really confusing and overloaded. Since "-accel" is our preferred way to enable an accelerator nowadays, and "-accel hax" is even less to type than "-enable-hax", let's deprecate the "-enable-hax" option now. Note: While "-enable-kvm" is available since a long time and can hardly be removed since it is used in a lot of upper layer tools and scripts, the "-enable-hax" option is still rather new and not very widespread yet, so I think that it should be OK if we remove this in a couple of releases again (we'll see whether someone complains after seeing the deprecation message - then we could still reconsider to keep it if there a well-founded reasons).

The -drive options cyls, heads, secs and trans were deprecated in QEMU 2.10. It's time to remove them. hd-geo-test tested both the old version with geometry options in -drive and the new one with -device. Therefore the code using -drive doesn't have to be replaced there, we just need to remove the -drive test cases. This in turn allows some simplification of the code.

2018-05-30cli: add --preconfig optionIgor Mammedov1-0/+13
This option allows pausing QEMU in the new RUN_STATE_PRECONFIG state, allowing the configuration of QEMU from QMP before the machine jumps into board initialization code of machine_run_board_init() The intent is to allow management to query machine state and additionally configure it using previous query results within one QEMU instance (i.e. eliminate the need to start QEMU twice, 1st to query board specific parameters and 2nd for actual VM start using query results for additional parameters). The new option complements -S option and could be used with or without it. The difference is that -S pauses QEMU when the machine is completely initialized with all devices wired up and ready to execute guest code (QEMU needs only to unpause VCPUs to let guest execute its code), while the "preconfig" option pauses QEMU early before board specific init callback (machine_run_board_init) is executed and allows the configuration of machine parameters which will be used by board init code. When early introspection/configuration is done, command 'exit-preconfig' should be used to exit RUN_STATE_PRECONFIG and transition to the next requested state (i.e. if -S is used then QEMU will pause the second time when board/device initialization is completed or start guest execution if -S isn't provided on CLI) PS: Initially 'preconfig' is planned to be used for configuring numa topology depending on board specified possible cpus layout.
