[PATCH 0/4] qemu: Fill in panic model automatically on aarch64
by Andrea Bolognani
Back when pvpanic-pci support was introduced 1.5 years ago (!), we
required the user to manually provide the model name. This is
incovenient and doesn't match the behavior seen on other
architectures. Make things more user friendly.
Andrea Bolognani (4):
tests: Add coverage for panic on riscv64
qemu: Refactor default panic model
qemu: Sometimes the default panic model doesn't exist
qemu: Use pvpanic by default on aarch64

[libvirt PATCH] ch: interface: correctly update nicindexes
by Pavel Hrdina
Originally nicindexes were updated only for VIR_DOMAIN_NET_TYPE_BRIDGE
and VIR_DOMAIN_NET_TYPE_DIRECT. The mentioned commit adds support for
NAT network mode and changes the code to update nicindexes for
VIR_DOMAIN_NET_TYPE_ETHERNET and VIR_DOMAIN_NET_TYPE_NETWORK as well.
It doesn't work as intended and after the change nicindexes are updated
only for VIR_DOMAIN_NET_TYPE_ETHERNET and VIR_DOMAIN_NET_TYPE_NETWORK.
Fixes: aa642090738eb276f7bd70dea97d3a4fd03d59e3

+ [size-iops-sec]
+
+Add or update a throttle group against specific *domain*.
+*group-name* specifies a unique throttle group name, which defines limit, and
+will be referenced by drives.
+*domain* (see also ``domblklist`` for listing these names).
+
+If no limit is specified, default them as all zeros, which will fail,
+Otherwise, set limits with these flags:
+*--total-bytes-sec* specifies total throughput limit as a scaled integer, the
+default being bytes per second if no suffix is specified.
+*--read-bytes-sec* specifies read throughput limit as a scaled integer, the
+default being bytes per second if no suffix is specified.
+*--write-bytes-sec* specifies write throughput limit as a scaled integer, the
+default being bytes per second if no suffix is specified.
+*--total-iops-sec* specifies total I/O operations limit per second.
+*--read-iops-sec* specifies read I/O operations limit per second.
+*--write-iops-sec* specifies write I/O operations limit per second.
+*--total-bytes-sec-max* specifies maximum total throughput limit as a scaled
+integer, the default being bytes per second if no suffix is specified
+*--read-bytes-sec-max* specifies maximum read throughput limit as a scaled
+integer, the default being bytes per second if no suffix is specified.
+*--write-bytes-sec-max* specifies maximum write throughput limit as a scaled
+integer, the default being bytes per second if no suffix is specified.
+*--total-iops-sec-max* specifies maximum total I/O operations limit per second.
+*--read-iops-sec-max* specifies maximum read I/O operations limit per second.
+*--write-iops-sec-max* specifies maximum write I/O operations limit per second.
+*--total-bytes-sec-max-length* specifies duration in seconds to allow maximum
+total throughput limit.
+*--read-bytes-sec-max-length* specifies duration in seconds to allow maximum
+read throughput limit.
+*--write-bytes-sec-max-length* specifies duration in seconds to allow maximum
+write throughput limit.
+*--total-iops-sec-max-length* specifies duration in seconds to allow maximum
+total I/O operations limit.
+*--read-iops-sec-max-length* specifies duration in seconds to allow maximum
+read I/O operations limit.
+*--write-iops-sec-max-length* specifies duration in seconds to allow maximum
+write I/O operations limit.
+*--size-iops-sec* specifies size I/O operations limit per second.
+
+Bytes and iops values are independent, but setting only one value (such
+as --read-bytes-sec) resets the other two in that category to unlimited.
+An explicit 0 also clears any limit. A non-zero value for a given total
+cannot be mixed with non-zero values for read or write.
+
+It is up to the hypervisor to determine how to handle the length values.
+For the QEMU hypervisor, if an I/O limit value or maximum value is set,
+then the default value of 1 second will be displayed. Supplying a 0 will
+reset the value back to the default.
+
+If *--live* is specified, affect a running guest.
+If *--config* is specified, affect the next start of a persistent guest.
+If *--current* is specified, it is equivalent to either *--live* or
+*--config*, depending on the current state of the guest.
+When setting the disk io parameters both *--live* and *--config* flags may be
+given, but *--current* is exclusive. If no flag is specified, behavior
+is different depending on hypervisor.
+
+
+domthrottlegroupdel
+-------------------
+
+**Syntax:**
+
+::
+
+ domthrottlegroupdel domain group-name [[--config] [--live] | [--current]]
+
+Delete a Throttlegroup from the domain using the specified *group-name*.
+If an Throttlegroup is currently referenced by a disk resource such as via the
+``attach-disk`` command, then the attempt to remove the Throttlegroup will fail.
+If the *group-name* does not exist an error will occur.
+
+If *--live* is specified, affect a running guest. If the guest is not
+running an error is returned.
+If *--config* is specified, affect the next start of a persistent guest.
+If *--current* is specified, it is equivalent to either *--live* or
+*--config*, depending on the current state of the guest.
+
+
+domthrottlegroupinfo
+--------------------
+
+**Syntax:**
+
+::
+
+ domthrottlegroupinfo domain group-name [[--config] [--live] | [--current]]
+
+Display domain Throttlegroup information including I/O limits setting.
+
+If *--live* is specified, get the Throttlegroup data from the running guest. If
+the guest is not running, an error is returned.
+If *--config* is specified, get the Throttlegroup data from the next start of
+a persistent guest.
+If *--current* is specified or *--live* and *--config* are not specified,
+then get the Throttlegroup data based on the current guest state, which can
+either be live or offline.
+
+
+domthrottlegrouplist
+--------------------
+
+**Syntax:**
+
+::
+
+ domthrottlegrouplist domain [--inactive]
+
+Print a table showing names of all throttle groups
+associated with *domain*. If *--inactive* is specified, query the
+block devices that will be used on the next boot, rather than those
+currently in use by a running domain.

[PATCH RFC v4 13/17] qemuxmlconftest: Add 'throttlefilter' tests
by danielwuwy＠163.com
From: Chun Feng Wu <danielwuwy(a)163.com>
Test domain xml and status xml
* Add tests for "throttlegroup" domain xml processing, including
groups referenced and not referenced by filters
* Add tests for "throttlefilter" domain xml processing, including
throttle group referenced by different disks
* Add negative test case to report error when iotune is configured
together with throttle filters
* Add tests for throttlefilter nodename parse and format for statusxml
(disk/privateData/nodenames/nodename with type='throttle-filter')
* Add iotune limited disk tests to make sure iotune refactory works

[PATCH RFC v4 12/17] config: validate: Verify iotune, throttle group and filter
by danielwuwy＠163.com
From: Chun Feng Wu <danielwuwy(a)163.com>
Refactor iotune verification, and verify some rules
* Disk iotune validation can be reused for throttle group validation,
refactor it into common method "virDomainDiskIoTuneValidate"
* Add "virDomainDefValidateThrottleGroups" to validate throttle groups,
which in turn calls "virDomainDiskIoTuneValidate"
* Make sure referenced throttle group exists
* Use "iotune" and "throttlefilters" exclusively for specific disk
* Throttle filters cannot be used together with CDROM

[PATCH RFC v4 01/17] schema: Add new domain elements to support multiple throttle groups
by danielwuwy＠163.com
From: Chun Feng Wu <danielwuwy(a)163.com>
Introduce schema for defining '<throttlegroups>' element which
configures throttling groups which can be configured for multiple
disks.
* Refactor "diskIoTune" to extract common schema "iotune"
* Add new elements '<throttlegroups>'
* <ThrottleGroups> contains <ThrottleGroup> defintion, which references
"iotune"

+and then reference them within ``throttlefilters``(sub-element of ``disk`` element)
+to form filter chain in QEMU for specific disk. The limits(throttlegroups) are
+shared within domain, hence the same group can be referenced by different filters.

[PATCH RFC v4 00/17] Support throttle block filters
by danielwuwy＠163.com
From: Chun Feng Wu <danielwuwy(a)163.com>
Hi,
I am thinking to leverage "throttle block filter" in QEMU to support more flexible I/O limits(e.g. tiered I/O groups), one sample provided by QEMU doc is:
https://github.com/qemu/qemu/blob/master/docs/throttle.txt
"For example, let's say that we have three different drives and we want to set I/O limits for
each one of them and an additional set of limits for the combined I/O of all three drives."
The implementation idea is to
- Define throttle groups(limit) in domain
- Define throttle filter to reference throttle group within disk
- Within domain disk, throttle filters references multiple throttle groups to form filter chain to apply multiple limits in QEMU like above sample
- Add new virsh cmds for throttle group management:
domthrottlegroupset Add or update a throttling group.
domthrottlegroupdel Delete a throttling group.
domthrottlegroupinfo Get a throttling group.
domthrottlegrouplist list all domain throttlegroups
- Update "attach-disk" to add one more option "--throttle-groups" to apply throttle filters e.g. "virsh attach-disk $VM_ID ${DISK_PATH}/vm1_disk_2.qcow2 vdd --driver qemu --subdriver qcow2 --targetbus virtio --throttle-groups limit2,limit012"
- I chose above semantics as I felt they're appropriate, if there are better ones please kindly suggest.
Note, this implementation requires flag "QEMU_CAPS_OBJECT_JSON".
From QMP perspective, the sample flow works this way:
- Throttle group creation:
virsh qemu-monitor-command 1 '{"execute":"object-add", "arguments":{"qom-type":"throttle-group","id":"limit0","limits":{"iops-total":200,"iops-read":0,"iops-total-max":200,"iops-total-max-length":1}}}'
virsh qemu-monitor-command 1 '{"execute":"object-add", "arguments":{"qom-type":"throttle-group","id":"limit1","limits":{"iops-total":250,"iops-read":0,"iops-total-max":250,"iops-total-max-length":1}}}'
virsh qemu-monitor-command 1 '{"execute":"object-add", "arguments":{"qom-type":"throttle-group","id":"limit2","limits":{"iops-total":300,"iops-read":0,"iops-total-max":300,"iops-total-max-length":1}}}'
virsh qemu-monitor-command 1 '{"execute":"object-add", "arguments":{"qom-type":"throttle-group","id":"limit012","limits":{"iops-total":400,"iops-read":0,"iops-total-max":400,"iops-total-max-length":1}}}'
- Chain up filters during attaching disk to apply two filters(limit0 and limit012):
virsh qemu-monitor-command 1 '{"execute":"blockdev-add", "arguments": {"driver":"file","filename":"/virt/disks/vm1_disk_1.qcow2","node-name":"test-3-storage","auto-read-only":true,"discard":"unmap"}}'
virsh qemu-monitor-command 1 '{"execute":"blockdev-add", "arguments":{"node-name":"test-4-format","read-only":false,"driver":"qcow2","file":"test-3-storage","backing":null}}'
virsh qemu-monitor-command 1 '{"execute":"blockdev-add", "arguments":{"driver":"throttle","node-name":"libvirt-5-filter","throttle-group": "limit0","file":"test-4-format"}}'
virsh qemu-monitor-command 1 '{"execute":"blockdev-add", "arguments": {"driver":"throttle","node-name":"libvirt-6-filter","throttle-group":"limit012","file":"libvirt-5-filter"}}'
virsh qemu-monitor-command 1 '{"execute": "device_add", "arguments": {"driver":"virtio-blk-pci","scsi":false,"bus":"pci.0","addr":"0x5","drive":"libvirt-6-filter","id":"virtio-disk1"}}'
This patchset includes:
- schema: Add new domain elements to support multiple throttle groups
- schema: Add new domain elements to support multiple throttle filters
- config: Introduce ThrottleGroup and corresponding XML parsing
- config: Introduce ThrottleFilter and corresponding XML parsing
- qemu: monitor: Add support for ThrottleGroup operations
- tests: Test qemuMonitorJSONGetThrottleGroup and qemuMonitorJSONUpdateThrottleGroup
- remote: New APIs for ThrottleGroup lifecycle management
- qemu: Refactor qemuDomainSetBlockIoTune to extract common methods
- qemu: Implement qemu driver for throttle API
- qemu: helper: throttle filter nodename and preparation processing
- qemu: block: Support block disk along with throttle filters
- config: validate: Verify iotune, throttle group and filter
- qemuxmlconftest: Add 'throttlefilter' tests
- test_driver: Test throttle group lifecycle APIs
- virsh: Refactor iotune options for re-use
- virsh: Add support for throttle group operations
- virsh: Add option "throttle-groups" to "attach_disk"
v4 changes:
- Format commit msgs
- Update version to '10.7.0'
- Update formatdomain.rst to remove nodename chain sample which exists in QEMU, and add description that order within <throttlefilters> doesn't mater
- delete "virDomainThrottleGroupFind", which is duplicate to "virDomainThrottleGroupByName"
- Remove "id" within _virDomainThrottleFilterDef, which is not required
- Avoid export for methods not used anywhere else
- Add manpage for new virsh cmds and options
- Update error code&msg
- Consolidate validation logic into one commit
- Format throttle filter nodename into disk/privateData/nodenames/nodename(type='throttle-filter') and parse it reversely
- Add tests for statusxml(disk/privateData/nodenames/nodename) test regarding throttle filter nodename parse and format
- Add more complicated test cases and negative case for throttle filter xml
- Add a 'throttle-' prefix so that we clearly separate the throttle group objects into their own QEMU namespace.
- Update virDomainGetThrottleGroup and virDomainDelThrottleGroup to remove TYPED_PARAM_STRING check
- Update remote_protocol.x "REMOTE_PROC_DOMAIN_DEL_THROTTLE_GROUP" to set "@acl: domain:write" rather than "read"
- Split commit of "qemu: Implement qemu driver for throttle API" into two commits
- Check QEMU_CAPS_OBJECT_JSON when vm is virDomainObjIsActive(vm), and update error msg
- Address leak in qemuBuildThrottleFiltersAttachPrepareBlockdev
- Prefix new cmd with "dom", e.g. domthrottlegroupset
- Refactor completer and "domthrottlegrouplist" to share the same method "virshGetThrottleGroupNames"
- Update qemuBlockThrottleFilterAttachPrepareBlockdev to remove "data->filterAttached = true;"
- Support CopyOnRead by re-org chain: device -> throttle -> copyOnRead Layer-> image chain
Any comments/suggestions will be appriciated!
