[PATCH RFC v2 00/12] Support throttle block filters
by wucf＠linux.ibm.com
From: Chun Feng Wu <wucf(a)linux.ibm.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:
throttlegroupset Add or update a throttling group.
throttlegroupdel Delete a throttling group.
throttlegroupinfo Get a throttling group.
throttlegrouplist 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.
This patchset includes:
- Throttle group and throttle filter definition in patch 1
- New QMP processing to update and get throttle group in patch 2
- New API definition and implementation in patch 3
- QEMU driver implementation in patch 4
- Hotplug and qemuProcessLaunch flow implemenation in patch 5,6
- Domain XML schema and doc(formatdomain.rst) change in patch 7
- Tests in patch 8,9
- Virsh cmd implementation in patch 10
- Other verification implementation in patch 11, 12
v2 changes:
- fix failure caused by "check-remote_protocol" between patch 3 and patch 9 in v1
- make sure coding style is consistent about function declaration
- patch 3 in v1 is splitted into two commits: "remote: New APIs for ThrottleGroup lifecycle management" and "qemu: Implement qemu driver for throttle API"
- replace "// comment" with "/* comment */"
- avoid empty 'cleanup' labels
- use "virJSONValueObjectAdd(&limits, "P:name", value)" to avoid introducing extra helper, and check return value
- preserve spacing between blocks of code which are not related
- remove "VSH_OT_ALIAS" section for new cmds in virsh_domain.c
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-3-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-3-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"}}'
Any comments/suggestions will be appriciated!

[PATCH rfcv4 00/13] LIBVIRT: X86: TDX support
by Zhenzhong Duan
Hi,
This series brings libvirt the x86 TDX support.
* What's TDX?
TDX stands for Trust Domain Extensions which isolates VMs from
the virtual-machine manager (VMM)/hypervisor and any other software on
the platform.
To support TDX, multiple software components, not only KVM but also QEMU,
guest Linux and virtual bios, need to be updated. For more details, please
check link[1].
This patchset is another software component to extend libvirt to support TDX,
with which one can start a TDX guest from high level rather than running qemu
directly.
* Misc
As QEMU use a software emulated way to reset guest which isn't supported by TDX
guest for security reason. We simulate reboot for TDX guest by kill and create a
new one in FakeReboot framework.
Complete code can be found at [2], matching qemu code can be found at [3].
There is a 'debug' property for tdx-guest object which isn't in matching qemu[3]
yet. I keep them intentionally as they will be implemented in qemu as extention
series of [3].
* Test
start/stop/reboot with virsh
stop/reboot trigger in guest
stop with on_poweroff=destroy/restart
reboot with on_reboot=destroy/restart
* Patch organization
- patch 1-4: Support query of TDX capabilities.
- patch 5-8: Add TDX type to launchsecurity framework.
- patch 9-11: Add reboot support to TDX guest
- patch 12-13: Add test and docs
TODO:
- update QEMU capabilities data in tests, depending on qemu TDX merged beforehand
- add reconnect logic in virsh command

[PATCH] ci: Always run 'pages' job
by Peter Krempa
When the 'pages' job is configured to run 'on_success' it's skipped if
any other pipeline fails. This is bad in cases such as if an external
service runs out of CI minutes as the web stops being updated.
Since the 'artifacts' of the 'website_job' are generated only if that
phase succeeds this will update the web when the web part is buildable.
Signed-off-by: Peter Krempa <pkrempa(a)redhat.com>

Note that it's upnpleasant to test the pages deployment stuff separately
as various hacks are needed to do that successfully. Let's test this one
in production.

Add iommu device when VM configured with > 255 vcpus
by Jim Fehlig
Hi All,
I vaguely recall a discussion about $subject, but can't find it now. Perhaps
buried in another thread. The topic has been raised internally again, and I'd
like to gauge the community's interest in automatically adding the necessary
devices/config when user has specified vcpus > 255.
The comparison for prior art is a bit of a stretch, but we e.g. add <audio
type='spice'/> when spice graphics is configured. I know libvirt has generally
tried to avoid policy decisions, but it's not clear to me where we stand with
cases such as this, where every x86 VM with > 255 vcpus needs a similarly
configured iommu.
Regards,
Jim
