2022-04-25block: add 'force' parameter to 'blockdev-change-medium' commandDenis V. Lunev1-0/+6
'blockdev-change-medium' is a convinient wrapper for the following sequence of commands: * blockdev-open-tray * blockdev-remove-medium * blockdev-insert-medium * blockdev-close-tray and should be used f.e. to change ISO image inside the CD-ROM tray. Though the guest could lock the tray and some linux guests like CentOS 8.5 actually does that. In this case the execution if this command results in the error like the following: Device 'scsi0-0-1-0' is locked and force was not specified, wait for tray to open and try again. This situation is could be resolved 'blockdev-open-tray' by passing flag 'force' inside. Thus is seems reasonable to add the same capability for 'blockdev-change-medium' too. Signed-off-by: Denis V.

Applications such as Gnome may use Alt-Tab and Super-Tab for different purposes, some use Ctrl-arrows so we want to allow qemu to handle everything when it captures the mouse/keyboard. However, Mac OS handles some combos like Command-Tab and Ctrl-arrows at an earlier part of the event handling chain, not letting qemu see it. We add a global Event Tap that allows qemu to see all events when the mouse is grabbed. Note that this requires additional permissions.

2022-03-07block/nbd: support override of hostname for TLS certificate validationDaniel P. Berrangé1-0/+3
When connecting to an NBD server with TLS and x509 credentials, the client must validate the hostname it uses for the connection, against that published in the server's certificate. If the client is tunnelling its connection over some other channel, however, the hostname it uses may not match the info reported in the server's certificate. In such a case, the user needs to explicitly set an override for the hostname to use for certificate validation. This is achieved by adding a 'tls-hostname' property to the NBD block driver.

2022-03-07block: introduce snapshot-access block driverVladimir Sementsov-Ogievskiy1-1/+3
The new block driver simply utilizes snapshot-access API of underlying block node. In further patches we want to use it like this: [guest] [NBD export] | | | root | root v file v [copy-before-write]<------[snapshot-access] | | | file | target v v [active-disk] [temp.img] This way, NBD client will be able to read snapshotted state of active disk, when active disk is continued to be written by guest. This is known as "fleecing", and currently uses another scheme based on qcow2 temporary image which backing file is active-disk. New scheme comes with benefits - see next commit. The other possible application is exporting internal snapshots of qcow2, like this: [guest] [NBD export] | | | root | root v file v [qcow2]<---------[snapshot-access] For this, we'll need to implement snapshot-access API handlers in qcow2 driver, and improve snapshot-access block driver (and API) to make it possible to select snapshot by name. Another thing to improve is size of snapshot. Now for simplicity we just use size of bs->file, which is OK for backup, but for qcow2 snapshots export we'll need to imporve snapshot-access API to get size of snapshot.

2022-03-02qapi/monitor: allow VNC display id in set/expire_passwordStefan Reiter1-22/+74
It is possible to specify more than one VNC server on the command line, either with an explicit ID or the auto-generated ones à la "default", "vnc2", "vnc3", ... It is not possible to change the password on one of these extra VNC displays though. Fix this by adding a "display" parameter to the "set_password" and "expire_password" QMP and HMP commands. For HMP, the display is specified using the "-d" value flag. For QMP, the schema is updated to explicitly express the supported variants of the commands with protocol-discriminated unions.

2022-02-28qapi: Move RTC_CHANGE back out of target schemaPeter Maydell2-33/+22
This commit effectively reverts commit 183e4281a30962, which moved the RTC_CHANGE event to the target schema. That change was an attempt to make the event target-specific to improve introspection, but the event isn't really target-specific: it's machine or device specific. Putting RTC_CHANGE in the target schema with an ifdef list reduces maintainability (by adding an if: list with a long list of targets that needs to be manually updated as architectures are added or removed or as new devices gain the RTC_CHANGE functionality) and increases compile time (by preventing RTC devices which emit the event from being "compile once" rather than "compile once per target", because qapi-events-misc-target.h uses TARGET_* ifdefs, which are poisoned in "compile once" files.) Move RTC_CHANGE back to misc.json.

2022-02-28qapi/migration: Fix examples document wrong field name for argumentsFabian Holler1-5/+5
The examples for the snapshot-* and calc-dirty-rate commands document that arguments for the commands are passed in a 'data' field. This is wrong, passing them in a "data" field results in the error: {"error": {"class": "GenericError", "desc": "QMP input member 'data' is unexpected"}} Arguments are expected to be passed in an field called "arguments".
