* block: Remove deprecated -drive geometry optionsKevin Wolf2018-06-151-1/+0Star
| | | | | | | | | | | | | 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.

* hmp: Allow using a qdev id in block_set_io_throttleAlberto Garcia2018-05-151-1/+2
| | | | | | | | | | | | | | | | The QMP version of this command can take a qdev ID since 7a9877a02635, but the HMP version is still using the deprecated block device name so there's no way to refer to a block device added like this: -blockdev node-name=disk0,driver=qcow2,file.driver=file,file.filename=hd.qcow2 -device virtio-blk-pci,id=virtio-blk-pci0,drive=disk0 This patch works around this problem by using the specified name as a qdev ID if the block device name is not found.

* block/mirror: change the semantic of 'force' of block-job-cancelLiang Li2018-03-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When doing drive mirror to a low speed shared storage, if there was heavy BLK IO write workload in VM after the 'ready' event, drive mirror block job can't be canceled immediately, it would keep running until the heavy BLK IO workload stopped in the VM. Libvirt depends on the current block-job-cancel semantics, which is that when used without a flag after the 'ready' event, the command blocks until data is in sync. However, these semantics are awkward in other situations, for example, people may use drive mirror for realtime backups while still wanting to use block live migration. Libvirt cannot start a block live migration while another drive mirror is in progress, but the user would rather abandon the backup attempt as broken and proceed with the live migration than be stuck waiting for the current drive mirror backup to finish. The drive-mirror command already includes a 'force' flag, which libvirt does not use, although it documented the flag as only being useful to quit a job which is paused. However, since quitting a paused job has the same effect as abandoning a backup in a non-paused job (namely, the destination file is not in sync, and the command completes immediately), we can just improve the documentation to make the force flag obviously useful.

| | | | | | | | | | | | | | | | | | | | | | | | | Define two new migration parameters to be used with TLS encryption. The 'tls-creds' parameter provides the ID of an instance of the 'tls-creds' object type, or rather a subclass such as 'tls-creds-x509'. Providing these credentials will enable use of TLS on the migration data stream. If using x509 certificates, together with a migration URI that does not include a hostname, the 'tls-hostname' parameter provides the hostname to use when verifying the server's x509 certificate. This allows TLS to be used in combination with fd: and exec: protocols where a TCP connection is established by a 3rd party outside of QEMU. NB, this requires changing the migrate_set_parameter method in the HMP to accept a 's' (string) value instead of 'i' (integer). This is backwards compatible, because the parsing of strings allows the quotes to be optional, thus any integer is also a valid string.

* hmp: 'drive_add -n' for creating a node without BBKevin Wolf2016-03-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds an option to the drive_add HMP command to create only a BlockDriverState without a BlockBackend on top. The motivation for this is that libvirt needs to specify options to a migration target (specifically, detect-zeroes). drive-mirror doesn't allow specifying options, and the proper way to do this is to create the target BDS separately with blockdev-add (where you can specify options) and then use blockdev-mirror to that BDS. However, libvirt can't use blockdev-add as long as it is still experimental, and we're expecting that it will still take some time, so we need to resort to drive_add. The problem with drive_add is that so far it always created a BB, and BDSes with a BB can't be used as a mirroring target as long as we don't support multiple BBs per BDS - and while we're working towards that goal, it's another thing that will still take some time. So to achieve the goal, the simplest solution to provide the functionality now without adding one-off options to the mirror QMP commands is to extend drive_add to create nodes without BBs.

* monitor: allow device_del to accept QOM pathsDaniel P. Berrange2015-09-221-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently device_del requires that the client provide the device short ID. device_add allows devices to be created without giving an ID, at which point there is no way to delete them with device_del. The QOM object path, however, provides an alternative way to identify the devices. Allowing device_del to accept an object path ensures all devices are deletable regardless of whether they have an ID. (qemu) device_add usb-mouse (qemu) qom-list /machine/peripheral-anon device[0] (child<usb-mouse>) type (string) (qemu) device_del /machine/peripheral-anon/device[0] Devices are required to be marked as hotpluggable otherwise an error is raised (qemu) device_del /machine/unattached/device[4] Device 'PIIX3' does not support hotplugging Signed-off-by: Daniel P.

* monitor: Use trad. command interface for HMP pcie_aer_inject_errorMarkus Armbruster2015-06-021-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | All QMP commands use the "new" handler interface (mhandler.cmd_new). Most HMP commands still use the traditional interface (mhandler.cmd), but a few use the "new" one. Complicates handle_user_command() for no gain, so I'm converting these to the traditional interface. pcie_aer_inject_error's implementation is split into the hmp_pcie_aer_inject_error() and pcie_aer_inject_error_print(). The former is a peculiar crossbreed between HMP and QMP handler. On success, it works like a QMP handler: store QDict through ret_data parameter, return 0. Printing the QDict is left to pcie_aer_inject_error_print(). On failure, it works more like an HMP handler: print error to monitor, return negative number. To convert to the traditional interface, turn pcie_aer_inject_error_print() into a command handler wrapping around hmp_pcie_aer_inject_error(). By convention, this command handler should be called hmp_pcie_aer_inject_error(), so rename the existing hmp_pcie_aer_inject_error() to do_pcie_aer_inject_error().

* monitor: Make client_migrate_info synchronousMarkus Armbruster2015-04-271-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | Live migration with spice works like this today: (1) client_migrate_info monitor cmd (2) spice server notifies client, client connects to target host. (3) qemu waits until spice client connect is finished. (4) send over vmstate (i.e. main part of live migration). (5) spice handover to target host. (3) is implemented by making client_migrate_info a async monitor command. This is the only async monitor command we have. The original reason to implement this dance was that qemu did not accept new tcp connections while the incoming migration was running, so (2) and (4) could not be done in parallel. That issue was fixed long ago though. Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp connects while the incoming migration runs. Time to drop step (3). This patch does exactly that, by making the monitor command synchronous and removing the code needed to handle the async monitor command in ui/spice-core.c Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
