At the moment, there is no configuration option for the libvirt-guests
service that allows users to define that only persistent virtual machines
should be shutdown on host shutdown.
Currently, the service config allows to choose between two ON_SHUTDOWN
actions that are executed on running virtual machines when the host goes
down: shutdown, suspend.
The ON_SHUTDOWN action should be orthogonal to the type of the virtual
machine. However, the existing implementation, does not suspend
transient virtual machines.
This is the matrix of actions that is executed on virtual machines based
on the configured ON_SHUTDOWN action and the type of a virtual machine.
| persistent | transient
shutdown | shutdown | shutdown (what we want to change)
suspend | suspend | nothing
Add config option PERSISTENT_ONLY to libvirt-guests config that allows
users to define if the ON_SHUTDOWN action should be applied only on
persistent virtual machines. PERSISTENT_ONLY can be set to true, false,
default. The default option will implement the already existing logic.
Case 1: PERSISTENT_ONLY=default
| persistent | transient
shutdown | shutdown | shutdown
suspend | suspend | nothing
Case 2: PERSISTENT_ONLY=true
| persistent | transient
shutdown | shutdown | nothing
suspend | suspend | nothing
Case 3: PERSISTENT_ONLY=false
| persistent | transient
shutdown | shutdown | shutdown
suspend | suspend | suspend

The 10.2.0 release of both libvirt and libvirt-python is tagged and
signed tarballs are available at
https://download.libvirt.org/
https://download.libvirt.org/python/
Thanks everybody who helped with this release by sending patches,
reviewing, testing, or providing feedback. Your work is greatly
appreciated.
* New features
* ch: Basic save and restore support for ch driver
The ch driver now supports basic save and restore operations. This is
functional on domains without any network, host device config defined.
The `path` parameter for save and restore should be a directory.
* qemu: Support for driver type ``mtp`` in ``<filesystem/>`` devices
The ``mtp`` driver type exposes the ``usb-mtp`` device in QEMU. The
guest can access files on this driver through the Media Transfer
Protocol (MTP).
* qemu: Added support for the loongarch64 architecture
It is now possible for libvirt to run loongarch64 guests, including on
other architectures via TCG. For the best results, it is recommended to
use the upcoming QEMU 9.0.0 release together with the development version
of edk2.
* qemu: Introduce virDomainGraphicsReload API
Reloading the graphics display is now supported for QEMU guests using
VNC. This is useful to make QEMU reload the TLS certificates without
restarting the guest. Available via the ``virDomainGraphicsReload`` API
and the ``domdisplay-reload`` virsh command.
* Bug fixes
* qemu: Fix migration from libvirt older than 9.10.0 when vmx is enabled
A domain with vmx feature enabled (which may be even done automatically
with ``mode='host-model'``) started by libvirt 9.9.0 or older cannot be
migrated to libvirt 9.10.0, 10.0.0, and 10.1.0 as the target host would
complain about a lot of extra ``vmx-*`` features. Migration of similar
domains started by the affected releases to libvirt 9.9.0 and older
does not work either. Since libvirt 10.2.0 migration works again with
libvirt 9.9.0 and older in both directions. Migration from the affected
releases to 10.2.0 works as well, but the other direction remains broken
unless the fix is backported.
* node_device: Don't report spurious errors from PCI VPD parsing
In last release the PCI Vital Product Data parser was enhanced to report
errors but that effort failed as some kernels have the file but don't allow
reading it causing logs to be spammed with::
libvirtd[21055]: operation failed: failed to read the PCI VPD data
Since the data is used only in the node device XML and errors are ignored if
the parsing failed, this release removes all the error reporting.
* qemu: set correct SELinux label for unprivileged virtiofsd
It is now possible to use virtiofsd-based ``<filesystem>`` shares even
if the guest is confined using SELinux.
* qemu: fix a crash on unprivileged virtiofsd hotplug
Hotplugging virtiofsd-based filesystems works now.
* virt-admin: Fix segfault when libvirtd dies
``virt-admin`` no longer crashes when ``libvirtd`` unexpectedly closes
the connection.
Enjoy.

Though usb-net is not explicitly supported, it is already possible to use
usb-net devices directly with libvirt (Simply by setting model type as
'usb-net' and manually providing a USB address)
This patch series intends to fill in some remaining gaps.
1. Automatic USB address assignment
2. New testcase
[Changes in v2]
1. Drop qemu_capabilities patch
2. Fix documentation to reflect correct version.
3. Remove unnecessary comment.
4. Fix commit subject.

ISAPC machine was introduced 25 years ago and it's a lot of time since
such machine was around with real ISA only PC hardware practically defunct.
Also it's slowly bit-rots (for example: I was able to boot RHEL6 on RHEL9 host
in only TCG mode, while in KVM mode it hung in the middle of boot)
Rather than spending time on fixing 'the oldest' no longer tested machine type,
deprecate it so we can clean up QEMU code from legacy fixups and hopefully
make it easier to follow.
Folks who have to use ancient guest that requires ISAPC can still
use older QEMU to play with it.

Commit 2ecdf259299813c2c674377e22a0acbce5ccbbb2 was intended to
implement two things: reduce stack usage inside ACL helpers and
minimally initialize virDomainDef object to avoid passing garbage
inside validation framework. Though original commit has not
touched other ACL helpers.
This patch adds proper clauses to
remoteRelayNetworkEventCheckACL
remoteRelayStoragePoolEventCheckACL
remoteRelayNodeDeviceEventCheckACL
remoteRelaySecretEventCheckACL

When performing an install, it's common for tooling such as virt-install
to remove the install kernel/initrd once they are successfully booted and
the domain has been redefined to boot without them. After the installation
is complete and the domain is rebooted/shutdown, the DAC and selinux
security drivers attempt to restore labels on the now deleted files. It's
harmles wrt functionality, but results in error messages such as
Mar 08 12:40:37 virtqemud[5639]: internal error: child reported (status=125): unable to stat: /var/lib/libvirt/boot/vir>
Mar 08 12:40:37 virtqemud[5639]: unable to stat: /var/lib/libvirt/boot/virtinst-yvp19moo-linux: No such file or directo>
Mar 08 12:40:37 virtqemud[5639]: Unable to run security manager transaction
Avoid the messages by checking if the kernel and initrd still exist before
including them in the restore label transaction.

Per Daniel suggestion [*]:
> isapc could arguably be restricted to just 32-bit CPU models,

Display a warning when such CPU is used:
$ qemu-system-x86_64 -monitor stdio -S -M isapc -cpu Westmere
qemu-system-x86_64: warning: Use of 64-bit CPU 'Westmere' is deprecated on the ISA-only PC machine

The whole RDMA subsystem was deprecated in commit e9a54265f5
("hw/rdma: Deprecate the pvrdma device and the rdma subsystem")
released in v8.2. Time to remove it.
Keep the RAM_SAVE_FLAG_HOOK definition since it might appears
in old migration streams.
Remove the dependencies on libibumad and libibverbs.
Remove the generated vmw_pvrdma/ directory from linux-headers.
Remove RDMA handling from migration.
Remove RDMA handling in GlusterFS block driver.
Remove rdmacm-mux tool from contrib/.
Remove PVRDMA device.

-Paravirtualized RDMA Device (PVRDMA)
-====================================
-
-
-1. Description
-===============
-PVRDMA is the QEMU implementation of VMware's paravirtualized RDMA device.
-It works with its Linux Kernel driver AS IS, no need for any special guest
-modifications.
-
-While it complies with the VMware device, it can also communicate with bare
-metal RDMA-enabled machines as peers.
-
-It does not require an RDMA HCA in the host, it can work with Soft-RoCE (rxe).
-
-It does not require the whole guest RAM to be pinned allowing memory
-over-commit and, even if not implemented yet, migration support will be
-possible with some HW assistance.
-
-A project presentation accompany this document:
-- https://blog.linuxplumbersconf.org/2017/ocw/system/presentations/4730/origi…
-
-
-
-2. Setup
-========
-
-
-2.1 Guest setup
-===============
-Fedora 27+ kernels work out of the box, older distributions
-require updating the kernel to 4.14 to include the pvrdma driver.
-
-However the libpvrdma library needed by User Level Software is still
-not available as part of the distributions, so the rdma-core library
-needs to be compiled and optionally installed.
-
-Please follow the instructions at:
- https://github.com/linux-rdma/rdma-core.git
-
-
-2.2 Host Setup
-==============
-The pvrdma backend is an ibdevice interface that can be exposed
-either by a Soft-RoCE(rxe) device on machines with no RDMA device,
-or an HCA SRIOV function(VF/PF).
-Note that ibdevice interfaces can't be shared between pvrdma devices,
-each one requiring a separate instance (rxe or SRIOV VF).
-
-
-2.2.1 Soft-RoCE backend(rxe)
-===========================
-A stable version of rxe is required, Fedora 27+ or a Linux
-Kernel 4.14+ is preferred.
-
-The rdma_rxe module is part of the Linux Kernel but not loaded by default.
-Install the User Level library (librxe) following the instructions from:
-https://github.com/SoftRoCE/rxe-dev/wiki/rxe-dev:-Home
-
-Associate an ETH interface with rxe by running:
- rxe_cfg add eth0
-An rxe0 ibdevice interface will be created and can be used as pvrdma backend.
-
-
-2.2.2 RDMA device Virtual Function backend
-==========================================
-Nothing special is required, the pvrdma device can work not only with
-Ethernet Links, but also Infinibands Links.
-All is needed is an ibdevice with an active port, for Mellanox cards
-will be something like mlx5_6 which can be the backend.
-
-
-2.2.3 QEMU setup
-================
-Configure QEMU with --enable-rdma flag, installing
-the required RDMA libraries.
-
-
-
-3. Usage
-========
-
-
-3.1 VM Memory settings
-======================
-Currently the device is working only with memory backed RAM
-and it must be mark as "shared":
- -m 1G \
- -object memory-backend-ram,id=mb1,size=1G,share \
- -numa node,memdev=mb1 \
-
-
-3.2 MAD Multiplexer
-===================
-MAD Multiplexer is a service that exposes MAD-like interface for VMs in
-order to overcome the limitation where only single entity can register with
-MAD layer to send and receive RDMA-CM MAD packets.
-
-To build rdmacm-mux run
-# make rdmacm-mux
-
-Before running the rdmacm-mux make sure that both ib_cm and rdma_cm kernel
-modules aren't loaded, otherwise the rdmacm-mux service will fail to start.
-
-The application accepts 3 command line arguments and exposes a UNIX socket
-to pass control and data to it.
--d rdma-device-name Name of RDMA device to register with
--s unix-socket-path Path to unix socket to listen (default /var/run/rdmacm-mux)
--p rdma-device-port Port number of RDMA device to register with (default 1)
-The final UNIX socket file name is a concatenation of the 3 arguments so
-for example for device mlx5_0 on port 2 this /var/run/rdmacm-mux-mlx5_0-2
-will be created.
-
-pvrdma requires this service.
-
-Please refer to contrib/rdmacm-mux for more details.
-
-
-3.3 Service exposed by libvirt daemon
-=====================================
-The control over the RDMA device's GID table is done by updating the
-device's Ethernet function addresses.
-Usually the first GID entry is determined by the MAC address, the second by
-the first IPv6 address and the third by the IPv4 address. Other entries can
-be added by adding more IP addresses. The opposite is the same, i.e.
-whenever an address is removed, the corresponding GID entry is removed.
-The process is done by the network and RDMA stacks. Whenever an address is
-added the ib_core driver is notified and calls the device driver add_gid
-function which in turn update the device.
-To support this in pvrdma device the device hooks into the create_bind and
-destroy_bind HW commands triggered by pvrdma driver in guest.
-
-Whenever changed is made to the pvrdma port's GID table a special QMP
-messages is sent to be processed by libvirt to update the address of the
-backend Ethernet device.
-
-pvrdma requires that libvirt service will be up.
-
-
-3.4 PCI devices settings
-========================
-RoCE device exposes two functions - an Ethernet and RDMA.
-To support it, pvrdma device is composed of two PCI functions, an Ethernet
-device of type vmxnet3 on PCI slot 0 and a PVRDMA device on PCI slot 1. The
-Ethernet function can be used for other Ethernet purposes such as IP.
-
-
-3.5 Device parameters
-=====================
-- netdev: Specifies the Ethernet device function name on the host for
- example enp175s0f0. For Soft-RoCE device (rxe) this would be the Ethernet
- device used to create it.
-- ibdev: The IB device name on host for example rxe0, mlx5_0 etc.
-- mad-chardev: The name of the MAD multiplexer char device.
-- ibport: In case of multi-port device (such as Mellanox's HCA) this
- specify the port to use. If not set 1 will be used.
-- dev-caps-max-mr-size: The maximum size of MR.
-- dev-caps-max-qp: Maximum number of QPs.
-- dev-caps-max-cq: Maximum number of CQs.
-- dev-caps-max-mr: Maximum number of MRs.
-- dev-caps-max-pd: Maximum number of PDs.
-- dev-caps-max-ah: Maximum number of AHs.
-
-Notes:
-- The first 3 parameters are mandatory settings, the rest have their
- defaults.
-- The last 8 parameters (the ones that prefixed by dev-caps) defines the top
- limits but the final values is adjusted by the backend device limitations.
-- netdev can be extracted from ibdev's sysfs
- (/sys/class/infiniband/<ibdev>/device/net/)
-
-
-3.6 Example
-===========
-Define bridge device with vmxnet3 network backend:
-<interface type='bridge'>
- <mac address='56:b4:44:e9:62:dc'/>
- <source bridge='bridge1'/>
- <model type='vmxnet3'/>
- <address type='pci' domain='0x0000' bus='0x00' slot='0x10' function='0x0' multifunction='on'/>
-</interface>
-
-Define pvrdma device:
-<qemu:commandline>
- <qemu:arg value='-object'/>
- <qemu:arg value='memory-backend-ram,id=mb1,size=1G,share'/>
- <qemu:arg value='-numa'/>
- <qemu:arg value='node,memdev=mb1'/>
- <qemu:arg value='-chardev'/>
- <qemu:arg value='socket,path=/var/run/rdmacm-mux-rxe0-1,id=mads'/>
- <qemu:arg value='-device'/>
- <qemu:arg value='pvrdma,addr=10.1,ibdev=rxe0,netdev=bridge0,mad-chardev=mads'/>
-</qemu:commandline>
-

-
-
-4.1 Overview
-============
-The device acts like a proxy between the Guest Driver and the host
-ibdevice interface.
-On configuration path:
- - For every hardware resource request (PD/QP/CQ/...) the pvrdma will request
- a resource from the backend interface, maintaining a 1-1 mapping
- between the guest and host.
-On data path:
- - Every post_send/receive received from the guest will be converted into
- a post_send/receive for the backend. The buffers data will not be touched
- or copied resulting in near bare-metal performance for large enough buffers.
- - Completions from the backend interface will result in completions for
- the pvrdma device.
-
-
-4.2 PCI BARs
-============
-PCI Bars:
- BAR 0 - MSI-X
- MSI-X vectors:
- (0) Command - used when execution of a command is completed.
- (1) Async - not in use.
- (2) Completion - used when a completion event is placed in
- device's CQ ring.
- BAR 1 - Registers
- --------------------------------------------------------
- | VERSION | DSR | CTL | REQ | ERR | ICR | IMR | MAC |
- --------------------------------------------------------
- DSR - Address of driver/device shared memory used
- for the command channel, used for passing:
- - General info such as driver version
- - Address of 'command' and 'response'
- - Address of async ring
- - Address of device's CQ ring
- - Device capabilities
- CTL - Device control operations (activate, reset etc)
- IMG - Set interrupt mask
- REQ - Command execution register
- ERR - Operation status
-
- BAR 2 - UAR
- ---------------------------------------------------------
- | QP_NUM | SEND/RECV Flag || CQ_NUM | ARM/POLL Flag |
- ---------------------------------------------------------
- - Offset 0 used for QP operations (send and recv)
- - Offset 4 used for CQ operations (arm and poll)
-
-
-4.3 Major flows
-===============
-

- - Deallocates context
- - Acks the event to backend
-
-
-
-5. Limitations
-==============
-- The device obviously is limited by the Guest Linux Driver features implementation
- of the VMware device API.
-- Memory registration mechanism requires mremap for every page in the buffer in order
- to map it to a contiguous virtual address range. Since this is not the data path
- it should not matter much. If the default max mr size is increased, be aware that
- memory registration can take up to 0.5 seconds for 1GB of memory.
-- The device requires target page size to be the same as the host page size,
- otherwise it will fail to init.
-- QEMU cannot map guest RAM from a file descriptor if a pvrdma device is attached,
- so it can't work with huge pages. The limitation will be addressed in the future,
- however QEMU allocates Guest RAM with MADV_HUGEPAGE so if there are enough huge
- pages available, QEMU will use them. QEMU will fail to init if the requirements
- are not met.
-
-
-
-6. Performance
-==============
-By design the pvrdma device exits on each post-send/receive, so for small buffers
-the performance is affected; however for medium buffers it will became close to
-bare metal and from 1MB buffers and up it reaches bare metal performance.
-(tested with 2 VMs, the pvrdma devices connected to 2 VFs of the same device)
-
-All the above assumes no memory registration is done on data path.

-Introduction:
-=============
-
-RDMA helps make your migration more deterministic under heavy load because
-of the significantly lower latency and higher throughput over TCP/IP. This is
-because the RDMA I/O architecture reduces the number of interrupts and
-data copies by bypassing the host networking stack. In particular, a TCP-based
-migration, under certain types of memory-bound workloads, may take a more
-unpredictable amount of time to complete the migration if the amount of
-memory tracked during each live migration iteration round cannot keep pace
-with the rate of dirty memory produced by the workload.
-
-RDMA currently comes in two flavors: both Ethernet based (RoCE, or RDMA
-over Converged Ethernet) as well as Infiniband-based. This implementation of
-migration using RDMA is capable of using both technologies because of
-the use of the OpenFabrics OFED software stack that abstracts out the
-programming model irrespective of the underlying hardware.
-
-Refer to openfabrics.org or your respective RDMA hardware vendor for
-an understanding on how to verify that you have the OFED software stack
-installed in your environment. You should be able to successfully link
-against the "librdmacm" and "libibverbs" libraries and development headers
-for a working build of QEMU to run successfully using RDMA Migration.
-
-BEFORE RUNNING:
-===============
-
-Use of RDMA during migration requires pinning and registering memory
-with the hardware. This means that memory must be physically resident
-before the hardware can transmit that memory to another machine.
-If this is not acceptable for your application or product, then the use
-of RDMA migration may in fact be harmful to co-located VMs or other
-software on the machine if there is not sufficient memory available to
-relocate the entire footprint of the virtual machine. If so, then the
-use of RDMA is discouraged and it is recommended to use standard TCP migration.
-
-Experimental: Next, decide if you want dynamic page registration.
-For example, if you have an 8GB RAM virtual machine, but only 1GB
-is in active use, then enabling this feature will cause all 8GB to
-be pinned and resident in memory. This feature mostly affects the
-bulk-phase round of the migration and can be enabled for extremely
-high-performance RDMA hardware using the following command:
-
-QEMU Monitor Command:
-$ migrate_set_capability rdma-pin-all on # disabled by default
-
-Performing this action will cause all 8GB to be pinned, so if that's
-not what you want, then please ignore this step altogether.
-
-On the other hand, this will also significantly speed up the bulk round
-of the migration, which can greatly reduce the "total" time of your migration.
-Example performance of this using an idle VM in the previous example
-can be found in the "Performance" section.
-
-Note: for very large virtual machines (hundreds of GBs), pinning all
-*all* of the memory of your virtual machine in the kernel is very expensive
-may extend the initial bulk iteration time by many seconds,
-and thus extending the total migration time. However, this will not
-affect the determinism or predictability of your migration you will
-still gain from the benefits of advanced pinning with RDMA.
-
-RUNNING:
-========
-
-First, set the migration speed to match your hardware's capabilities:
-
-QEMU Monitor Command:
-$ migrate_set_parameter max-bandwidth 40g # or whatever is the MAX of your RDMA device
-
-Next, on the destination machine, add the following to the QEMU command line:
-
-qemu ..... -incoming rdma:host:port
-
-Finally, perform the actual migration on the source machine:
-
-QEMU Monitor Command:
-$ migrate -d rdma:host:port
-
-PERFORMANCE
-===========
-
-Here is a brief summary of total migration time and downtime using RDMA:
-Using a 40gbps infiniband link performing a worst-case stress test,
-using an 8GB RAM virtual machine:
-
-Using the following command:
-$ apt-get install stress
-$ stress --vm-bytes 7500M --vm 1 --vm-keep
-
-1. Migration throughput: 26 gigabits/second.
-2. Downtime (stop time) varies between 15 and 100 milliseconds.
-
-EFFECTS of memory registration on bulk phase round:
-
-For example, in the same 8GB RAM example with all 8GB of memory in
-active use and the VM itself is completely idle using the same 40 gbps
-infiniband link:
-
-1. rdma-pin-all disabled total time: approximately 7.5 seconds @ 9.5 Gbps
-2. rdma-pin-all enabled total time: approximately 4 seconds @ 26 Gbps
-
-These numbers would of course scale up to whatever size virtual machine
-you have to migrate using RDMA.
-
-Enabling this feature does *not* have any measurable affect on
-migration *downtime*. This is because, without this feature, all of the
-memory will have already been registered already in advance during
-the bulk round and does not need to be re-registered during the successive
-iteration rounds.
-
-RDMA Protocol Description:
-==========================
-
-Migration with RDMA is separated into two parts:
-
-1. The transmission of the pages using RDMA
-2. Everything else (a control channel is introduced)
-
-"Everything else" is transmitted using a formal
-protocol now, consisting of infiniband SEND messages.
-
-An infiniband SEND message is the standard ibverbs
-message used by applications of infiniband hardware.
-The only difference between a SEND message and an RDMA
-message is that SEND messages cause notifications
-to be posted to the completion queue (CQ) on the
-infiniband receiver side, whereas RDMA messages (used
-for VM's ram) do not (to behave like an actual DMA).
-
-Messages in infiniband require two things:
-
-1. registration of the memory that will be transmitted
-2. (SEND only) work requests to be posted on both
- sides of the network before the actual transmission
- can occur.
-
-RDMA messages are much easier to deal with. Once the memory
-on the receiver side is registered and pinned, we're
-basically done. All that is required is for the sender
-side to start dumping bytes onto the link.
-
-(Memory is not released from pinning until the migration
-completes, given that RDMA migrations are very fast.)
-
-SEND messages require more coordination because the
-receiver must have reserved space (using a receive
-work request) on the receive queue (RQ) before QEMUFileRDMA
-can start using them to carry all the bytes as
-a control transport for migration of device state.
-
-To begin the migration, the initial connection setup is
-as follows (migration-rdma.c):
-
-1. Receiver and Sender are started (command line or libvirt):
-2. Both sides post two RQ work requests
-3. Receiver does listen()
-4. Sender does connect()
-5. Receiver accept()
-6. Check versioning and capabilities (described later)
-
-At this point, we define a control channel on top of SEND messages
-which is described by a formal protocol. Each SEND message has a
-header portion and a data portion (but together are transmitted
-as a single SEND message).
-
-Header:
- * Length (of the data portion, uint32, network byte order)
- * Type (what command to perform, uint32, network byte order)
- * Repeat (Number of commands in data portion, same type only)
-
-The 'Repeat' field is here to support future multiple page registrations
-in a single message without any need to change the protocol itself
-so that the protocol is compatible against multiple versions of QEMU.
-Version #1 requires that all server implementations of the protocol must
-check this field and register all requests found in the array of commands located
-in the data portion and return an equal number of results in the response.
-The maximum number of repeats is hard-coded to 4096. This is a conservative
-limit based on the maximum size of a SEND message along with empirical
-observations on the maximum future benefit of simultaneous page registrations.
-
-The 'type' field has 12 different command values:
- 1. Unused
- 2. Error (sent to the source during bad things)
- 3. Ready (control-channel is available)
- 4. QEMU File (for sending non-live device state)
- 5. RAM Blocks request (used right after connection setup)
- 6. RAM Blocks result (used right after connection setup)
- 7. Compress page (zap zero page and skip registration)
- 8. Register request (dynamic chunk registration)
- 9. Register result ('rkey' to be used by sender)
- 10. Register finished (registration for current iteration finished)
- 11. Unregister request (unpin previously registered memory)
- 12. Unregister finished (confirmation that unpin completed)
-
-A single control message, as hinted above, can contain within the data
-portion an array of many commands of the same type. If there is more than
-one command, then the 'repeat' field will be greater than 1.
-
-After connection setup, message 5 & 6 are used to exchange ram block
-information and optionally pin all the memory if requested by the user.
-
-After ram block exchange is completed, we have two protocol-level
-functions, responsible for communicating control-channel commands
-using the above list of values:
-
-Logically:
-
-qemu_rdma_exchange_recv(header, expected command type)
-
-1. We transmit a READY command to let the sender know that
- we are *ready* to receive some data bytes on the control channel.
-2. Before attempting to receive the expected command, we post another
- RQ work request to replace the one we just used up.
-3. Block on a CQ event channel and wait for the SEND to arrive.
-4. When the send arrives, librdmacm will unblock us.
-5. Verify that the command-type and version received matches the one we expected.
-
-qemu_rdma_exchange_send(header, data, optional response header & data):
-
-1. Block on the CQ event channel waiting for a READY command
- from the receiver to tell us that the receiver
- is *ready* for us to transmit some new bytes.
-2. Optionally: if we are expecting a response from the command
- (that we have not yet transmitted), let's post an RQ
- work request to receive that data a few moments later.
-3. When the READY arrives, librdmacm will
- unblock us and we immediately post a RQ work request
- to replace the one we just used up.
-4. Now, we can actually post the work request to SEND
- the requested command type of the header we were asked for.
-5. Optionally, if we are expecting a response (as before),
- we block again and wait for that response using the additional
- work request we previously posted. (This is used to carry
- 'Register result' commands #6 back to the sender which
- hold the rkey need to perform RDMA. Note that the virtual address
- corresponding to this rkey was already exchanged at the beginning
- of the connection (described below).
-
-All of the remaining command types (not including 'ready')
-described above all use the aforementioned two functions to do the hard work:
-
-1. After connection setup, RAMBlock information is exchanged using
- this protocol before the actual migration begins. This information includes
- a description of each RAMBlock on the server side as well as the virtual addresses
- and lengths of each RAMBlock. This is used by the client to determine the
- start and stop locations of chunks and how to register them dynamically
- before performing the RDMA operations.
-2. During runtime, once a 'chunk' becomes full of pages ready to
- be sent with RDMA, the registration commands are used to ask the
- other side to register the memory for this chunk and respond
- with the result (rkey) of the registration.
-3. Also, the QEMUFile interfaces also call these functions (described below)
- when transmitting non-live state, such as devices or to send
- its own protocol information during the migration process.
-4. Finally, zero pages are only checked if a page has not yet been registered
- using chunk registration (or not checked at all and unconditionally
- written if chunk registration is disabled. This is accomplished using
- the "Compress" command listed above. If the page *has* been registered
- then we check the entire chunk for zero. Only if the entire chunk is
- zero, then we send a compress command to zap the page on the other side.
-
-Versioning and Capabilities
-===========================
-Current version of the protocol is version #1.
-
-The same version applies to both for protocol traffic and capabilities
-negotiation. (i.e. There is only one version number that is referred to
-by all communication).
-
-librdmacm provides the user with a 'private data' area to be exchanged
-at connection-setup time before any infiniband traffic is generated.
-
-Header:
- * Version (protocol version validated before send/recv occurs),
- uint32, network byte order
- * Flags (bitwise OR of each capability),
- uint32, network byte order
-
-There is no data portion of this header right now, so there is
-no length field. The maximum size of the 'private data' section
-is only 192 bytes per the Infiniband specification, so it's not
-very useful for data anyway. This structure needs to remain small.
-
-This private data area is a convenient place to check for protocol
-versioning because the user does not need to register memory to
-transmit a few bytes of version information.
-
-This is also a convenient place to negotiate capabilities
-(like dynamic page registration).
-
-If the version is invalid, we throw an error.
-
-If the version is new, we only negotiate the capabilities that the
-requested version is able to perform and ignore the rest.
-
-Currently there is only one capability in Version #1: dynamic page registration
-
-Finally: Negotiation happens with the Flags field: If the primary-VM
-sets a flag, but the destination does not support this capability, it
-will return a zero-bit for that flag and the primary-VM will understand
-that as not being an available capability and will thus disable that
-capability on the primary-VM side.
-
-QEMUFileRDMA Interface:
-=======================
-
-QEMUFileRDMA introduces a couple of new functions:
-
-1. qemu_rdma_get_buffer() (QEMUFileOps rdma_read_ops)
-2. qemu_rdma_put_buffer() (QEMUFileOps rdma_write_ops)
-
-These two functions are very short and simply use the protocol
-describe above to deliver bytes without changing the upper-level
-users of QEMUFile that depend on a bytestream abstraction.
-
-Finally, how do we handoff the actual bytes to get_buffer()?
-
-Again, because we're trying to "fake" a bytestream abstraction
-using an analogy not unlike individual UDP frames, we have
-to hold on to the bytes received from control-channel's SEND
-messages in memory.
-
-Each time we receive a complete "QEMU File" control-channel
-message, the bytes from SEND are copied into a small local holding area.
-
-Then, we return the number of bytes requested by get_buffer()
-and leave the remaining bytes in the holding area until get_buffer()
-comes around for another pass.
-
-If the buffer is empty, then we follow the same steps
-listed above and issue another "QEMU File" protocol command,
-asking for a new SEND message to re-fill the buffer.
-
-Migration of VM's ram:
-====================
-
-At the beginning of the migration, (migration-rdma.c),
-the sender and the receiver populate the list of RAMBlocks
-to be registered with each other into a structure.
-Then, using the aforementioned protocol, they exchange a
-description of these blocks with each other, to be used later
-during the iteration of main memory. This description includes
-a list of all the RAMBlocks, their offsets and lengths, virtual
-addresses and possibly includes pre-registered RDMA keys in case dynamic
-page registration was disabled on the server-side, otherwise not.
-
-Main memory is not migrated with the aforementioned protocol,
-but is instead migrated with normal RDMA Write operations.
-
-Pages are migrated in "chunks" (hard-coded to 1 Megabyte right now).
-Chunk size is not dynamic, but it could be in a future implementation.
-There's nothing to indicate that this is useful right now.
-
-When a chunk is full (or a flush() occurs), the memory backed by
-the chunk is registered with librdmacm is pinned in memory on
-both sides using the aforementioned protocol.
-After pinning, an RDMA Write is generated and transmitted
-for the entire chunk.
-
-Chunks are also transmitted in batches: This means that we
-do not request that the hardware signal the completion queue
-for the completion of *every* chunk. The current batch size
-is about 64 chunks (corresponding to 64 MB of memory).
-Only the last chunk in a batch must be signaled.
-This helps keep everything as asynchronous as possible
-and helps keep the hardware busy performing RDMA operations.
-
-Error-handling:
-===============
-
-Infiniband has what is called a "Reliable, Connected"
-link (one of 4 choices). This is the mode in which
-we use for RDMA migration.
-
-If a *single* message fails,
-the decision is to abort the migration entirely and
-cleanup all the RDMA descriptors and unregister all
-the memory.
-
-After cleanup, the Virtual Machine is returned to normal
-operation the same way that would happen if the TCP
-socket is broken during a non-RDMA based migration.
-
-TODO:
-=====
-1. Currently, 'ulimit -l' mlock() limits as well as cgroups swap limits
- are not compatible with infiniband memory pinning and will result in
- an aborted migration (but with the source VM left unaffected).
-2. Use of the recent /proc/<pid>/pagemap would likely speed up
- the use of KSM and ballooning while using RDMA.
-3. Also, some form of balloon-device usage tracking would also
- help alleviate some issues.
-4. Use LRU to provide more fine-grained direction of UNREGISTER
- requests for unpinning memory in an overcommitted environment.
-5. Expose UNREGISTER support to the user by way of workload-specific
- hints about application behavior.

I have just tagged v10.2.0-rc1 in the repository and pushed signed
tarballs to https://download.libvirt.org/
Please give the release candidate some testing and in case you find a
serious issue which should have a fix in the upcoming release, feel
free to reply to this thread to make sure the issue is more visible.
If you have not done so yet, please update NEWS.rst to document any
significant change you made since the last release.
Thanks,

Hi all!
The series aims to reach feature parity between job-* and block-job-*
APIs and finally deprecate block-job-* APIs.
01: new type-based unions for QAPI
02-07: rework block-job-change and add similar job-change command
08: support set-speed in new API (as an option to job-change)
09: support soft-cancelling ready mirror job in new API (as an
option to job-complete)
10-14: prepare query-jobs to substitute query-block-jobs
15: finally, deprecate old APIs
RFC: the series are untested. I plan to move tests to using new APIs
instead of deprecated ones in v2.
Vladimir Sementsov-Ogievskiy (15):
scripts/qapi: support type-based unions
qapi: rename BlockJobChangeOptions to JobChangeOptions
blockjob: block_job_change_locked(): check job type
qapi: block-job-change: make copy-mode parameter optional
qapi: JobChangeOptions: make type member optional and deprecated
blockjob: move change action implementation to job from block-job
qapi: add job-change
qapi: job-change: support speed parameter
qapi: job-complete: introduce no-block-replace option for mirror
qapi: query-jobs: add information specific for job type
job-qmp: job_query_single_locked: add assertion on job ret
qapi: rename BlockDeviceIoStatus to IoStatus
qapi: move IoStatus to common.json
qapi: query-job: add block-job specific information
qapi/block-core: derpecate block-job- APIs

This patch intends to add DMI support to libvirt for RISC-V and mips.
This change is based on commit ec6ce6363, which added ARM support.
This is not tested on the target arches, as I've been unable to find
hardware to test this on.

[PATCH 00/28] vsh: Fix handling of commands and help - part 2 (unwanted positional parsing of optional arguments)
by Peter Krempa 25 Mar '24
by Peter Krempa 25 Mar '24
25 Mar '24
Part 2 was supposed to be the refactor of the parser, but it turns out
that our annotations of arguments and quirks of the parser itself
resulted with basically every optional argument with value being also
considered for positional parisng.
This series explains where this happens and annotates all cases.
Peter Krempa (28):
vshCmddefHelp: Drop empty line at the end
virsh: cmdDomdisplayReload: Require option name for --type
vshCmddefCheckInternals: Improve some checks
virsh: Inline VIRSH_COMMON_OPT_DOMAIN_OT_STRING macro
virsh: Inline VIRSH_COMMON_OPT_FILE_FULL macro
virsh: Inline VIRSH_COMMON_OPT_NETWORK_OT_STRING macro
vsh: Introduce tool to find unwanted positional arguments to
'self-test'
vsh: Introduce annotation for vsh options which are unexpectedly
parsed positionally
virsh: Annotate '--diskspec' _ARGV options as unwanted positional
virsh: Annotate rest of _ARGV arguments as positional
vsh: Fix option formatting for 'VHS_OT_ARGV' options
virsh: Require option flags for 'blkdeviotune' arguments
virsh: Fix "positional" argument annotations for 'migrate' command
virsh: Require option flags for all optional arguments of
'attach-disk'
virsh-checkpoint: Make 'checkpointname' positional and required
vsh: Allow one optional positional argument
vsh: Make the only argument of 'connect', 'cd', and 'help' commands
positional
virsh: snapshot: Make 'snapshotname' argument positional
virsh: Make '(snapshot|checkpoint)-create' 'xmlfile' argument
positional
virsh-backup: Fix argument annotations of 'backup-begin' command
virsh: Annotate some optional arguments as positional
virsh: volume: Mark optional 'pool' argument as 'positional'
virsh: Annotate "unwanted_positional" arguments for
'pool-(define|create)-as' commands
virsh: Annodate 'unwanted_positional' arguments
virt-admin: Annodate 'unwanted_positional' arguments
vsh: Make positional parsing of arguments opt-in
vsh: Replace 'VSH_OFLAG_EMPTY_OK' bitwise flag with a separate struct
member
vshCmdOptDef: Remove unused 'flags' member

I ended up using and environment variable in the test_driver to fake jobs, so the application under test doesn't need to know anything. Would something like that be accepted?

I have managed to implement a PoC by introducing virDomainJobWait(), which checks the job type and if it's a dump it calls qemuDumpWaitForCompletion(), purely because it's the easiest thing to do (it fails with VIR_ERR_OPERATION_INVALID for all other operations). We'd like to implement this for all other job types and I'm looking for some pointers, is virCondWaitUntil(&priv->job.asyncCond, &obj->parent.lock) all that's required? (And return priv->job.error?)
Also, as I explained earlier, I want to implement joining a potentially existing dump job. In my specific use case, I want to either join an ongoing dump job if it exists, otherwise start a new one. I do this by calling virDomainGetJobStats(), but I'm thinking whether we could add a new, optional dump flag, e.g. 'join' which would make virDomainCoreDumpWithFormat do all this internally. Would something like that be accepted upstream.

If the original code detected a missing or null boot index in the
new XML, it automatically added the current value. This
autocompletion was incorrect because it was impossible to
distinguish between user intent and user error - changing the
boot order itself is forbidden and should always be an error.

For SEV-SNP support we will need to be able to specify versioned CPU models
that are not yet available in libvirt. Rather than just adding a versioned CPU
or two that would satisfy that immediate need, I decided to try to add
versioned CPUs in a more standard way. This series generates CPU definitions
for all cpu versions that are defined in upstream qemu (at least for
recent Intel and AMD CPUs).
libvirt already provides a select subset of these versions as configurable CPU
models. But we only include the ones that have defined aliases in qemu, such as
EPYC-IBPB. After this patchset, all verisioned cpu models supported by qemu
will be available in libvirt.
In addition to adding these new versioned models, based on feedback from Daniel
Berrange, I've also translated all CPU model aliases to a specific version when
specifying a CPU model to qemu. This means that we will no longer specify e.g.
'-cpu EPYC' to qemu, but will rather specify '-cpu EPYC-v1'
Changes in v3:
- handle unversioned aliases
Changes in v2:
- don't make any changes to existing CPU models
- drop concept of aliases from libvirt and only provide new versioned models
that aren't already available via their qemu alias.
Jonathon Jongsma (12):
cpu_map: update script to handle versioned CPUs
cpu_map: add canonical names to existing CPU models
cpu: parse the canonical name from the cpu model
qemu: use canonical name for CPU models
cpu_map: Add versioned EPYC CPUs
cpu_map: Add versioned Intel Skylake CPUs
cpu_map: Add versioned Intel Cascadelake CPUs
cpu_map: Add versioned Intel Icelake CPUs
cpu_map: Add versioned Intel Cooperlake CPUs
cpu_map: Add versioned Intel Snowridge CPUs
cpu_map: Add versioned Intel SapphireRapids CPUs
