[PATCH v2 0/1] Expose availability of SEV-ES
by Takashi Kajinami
This introduces the new "model" field in sev elements so that clients can
check whether SEV-ES, the 2nd generation of AMD SEV, is available in
the taget hyprvisor. There is the maxESGuests field (along with the maxGuests
field) but this field does not explain whether SEV-ES is actually
enabled in KVM.
Takashi Kajinami (1):
Expose available AMD SEV models in domain capabilities
Changes since v1:
* Fixed one code path where available models are not added
* Fixed missing update of "report" flag
* Updated the documentation to explain the new model field in addition
to the existing but undocumanted cpu0Id field

[PATCH] formatstorage: Document qcow2 default version change
by Peter Krempa
Based on discussion after commit f432114d9c was pushed it was pointed
out that the documentation still mentions the older version.
Fix the documentation to state the new version and introduce ambiguity
for future updates.

[PATCH v2 00/20] node_dev_udev: use workerpool and improve nodedev events
by Marc Hartmayer
When an udev event occurs for a mediated device (mdev) the mdev config data
requires an update via mdevctl as the udev event does not contain all config
data. This update needs to occur immediately and to be finished before the
libvirt nodedev event is issued to keep the API usage reliable.

[libvirt PATCH 00/28] native support for nftables in virtual network driver
by Laine Stump
This patch series enables libvirt to use nftables rules rather than
iptables *when setting up virtual networks* (it does *not* add
nftables support to the nwfilter driver). It accomplishes this by
abstracting several iptables functions (from viriptables.[ch] called
by the virtual network driver into a rudimentary "virNetfilter API"
(in virnetfilter.[ch], having the virtual network driver call the
virNetFilter API rather than calling the existing iptables functions
directly, and then finally adding an equivalent virNftables backend
that can be used instead of iptables (selected manually via a
network.conf setting, or automatically if iptables isn't found on the
host).
A first look at the result may have you thinking that it's filled with
a lot of bad decisions. While I would agree with that in many cases, I
think that overall they are the "least bad" decisions, or at least
"bad within acceptable limits / no worse than something else", and
point out that it's been done in a way that minimizes (actually
eliminates) the need for immediate changes to nwfilter (the other
consumer of iptables, which *also* needs to be updated to use native
nftables), and makes it much easier to change our mind about the
details in the future.
When I first started on this (long, protracted, repeatedly interrupted
for extended periods - many of these patches are > a year old) task, I
considered doing an all-at-once complete replacement of iptables with
nftables, since all the Linux distros we support have had nftables for
several years, and I'm pretty sure nobody has it disabled (not even
sure if it's possible to disable nftables while still enabling
iptables, since they both use xtables in the kernel). But due to
libvirt's use of "-t mangle -j CHECKSUM --checksum-fill" (see commit
fd5b15ff all the way back in July 2010 for details) which has no
equivalent in nftables rules (and we don't *want* it to!!), and the
desire to be able to easily switch back to iptables in case of an
unforeseen regression, we decided that both iptables and nftables need
to be supported (for now), with the default (for now) remaining as
iptables.
Just allowing for dual backends complicated matters, since it means
that we have to have a config file, a setting, detection of which
backends are available, and of course some sort of concept of an
abstracted frontend that can use either backend based on the config
setting (and/or auto-detection). Combining that with the fact that it
would just be "too big" of a project to switch over nwfilter's
iptables usage at the same time means that we have to keep around a
lot of existing code for compatibility's sake rather than just wiping
it all away and starting over.
So, what I've ended up with is:
1) a network.conf file (didn't exist before) with a single setting
"firewall_backend". If unset, the network driver tries to use iptables
on the backend, and if that's missing, then tries to use nftables.
2) a new (internal-only, so transient!) virNetFilterXXX API that is
used by the network driver in place of the iptablesXXX API, and calls
either iptablesXXX or:
3) a virNftablesXXX API that exactly replicates the filtering rules of
the existing iptablesXXX API (except in the custom "libvirt" base
table rather than the system "filter" and "nat" tables). This means
that:
4) when the nftables backend is used, the rules added are *exactly the
same* (functionally speaking) as we currently add for iptables (except
they are in the "libvirt" table).
We had spent some time in IRC discussing different ways of using new
functionality available in nftables to make a more
efficient/performant implemention of the desired filtering, and there
are some really great possibilities that need to be explored, but in
the end there were too many details up in the air, and I decided that
it would be more "accomplishable" (coined a new word there!) to first
replicate existing behavior with nftables, but do it inside a
framework that makes it easy to modify the details in the future (in
particular making it painless to switch back and forth between builds
with differing filter models at runtime) - this way we'll be able to
separate the infrastructure work from the details of the rules (which
we can then more easily work on and experiment with). (This implies
that the main objective right now is "get rid of iptables
dependencies", not "make the filtering faster and more efficient").
Notable features of this patchset:
* allows switching between iptables/nftables backends without
rebooting or restarting networks/guests.
Because the commands required to remove a network's filter rules are
now saved in the network status XML, each time libvirtd (or
virtnetworkd) is restarted, it will execute exactly the commands
needed to remove the filter rules that had been added by the
previous libvirtd/virtnetworkd (rather than just making a guess, as
we've always done up until now), and then add new rules using the
current backend+binary's set of rules (while also saving the info
needed for future removal of these new rules back into the network's
status XML).
* firewall_backend can be explicitly set in (new)
/etc/libvirt/network.conf, but if it's not explicitly set, libvirt
will default to the iptables backend if the iptables binary is
found, and otherwise fall back to nftables as long as the nft
binary is found; otherwise the first attempt to start a network will
fail with an appropriate error.
Things that seem ugly / that I would like to clean up / that I think
are just fine as they are:
* virFirewall does *not* provide a backend-agnostic interface [this is fine]
* We need to maintain a backward-compatible API for virFirewall so
that we don't have to touch nwfilter code. Trying to make its API
backend-agnostic would require individually considering/changing
every nwfilter use of virFirewall.
* instead virFirewall objects are just a way to build a collection
of commands to execute to build a firewall, then execute them
while collecting info for and building a collection of commands
that will tear down that firewall in the future.
Do I want to "fix" this in the future by making virFirewall a higher
level interface that accepts tokens describing the type of rule to
add (rather than backend-specific arguments to a backend-specific
command)? No. I think I like the way virFirewall works (as
described in that previous bullet-point), instead I'm thinking that
it is just slightly mis-named - I've lately been thinking of it as a
"virNetFilterCmdList". Similarly, the virFirewallRules that it has a
list of aren't really "rules", they are better described as commands
or actions, so maybe they should be renamed to virNetfilterCmd or
virNetfilterAction. But that is just cosmetic, so I didn't want to
get into it in these patches (especially in case someone disagrees,
or has a better idea for naming).
* Speaking of renaming - I should probably rename all the
"iptablesXXX" functions to "virIptablesXXX" to be consistent with so
much of our other code. I lost the ambition to deal with it right
now though, so I'm leaving that for later cleanup (or I could do it
now if it really makes someone's day :-).
* I could have chosen a higher place in the callchain to make the
virNetfilter abstraction, e.g. at the level of
"networkAddXXXFirewallRules()" rather than at the lower level of
iptablesXXX(). That is actually probably what will happen in the
future (since it will be necessary in order for an nftables-based
firewall to be significantly different in structure from an
iptables-based firewall). But that's the beauty of an API being
private - we can freely add/remove things as needed. the important
thing is that we now have the basic structure there.
For now, the split is just above the existing iptablesXXX API
(util/viriptables.[ch], which seems like a "narrow" enough
place. Most iptablesXXX functions are written in terms of just 10
*other* iptablesXXX functions that add iptables-specific commands -
I've just moved those functions into virnetfilter.[ch]
(appropriately renamed), and changed them to call the 10
virNetfilterXXX functions that will in-turn call those 10
iptablesXXX (or equivalent virNftablesXXX) functions.
* Some people may dislike that the 10 virNetfilterXXX functions are
each written with a switch statement that has cases to directly call
each backend, rather than each backend driver having a table of
pointers to API functions, with the virNetfilter API function
calling backends[fwBackend]->XXX() (ie the pattern for so many
drivers in libvirt). But for just 2 backends, that really seemed
like overkill and unnecessary obfuscation.
* As implemented here, I am storing a "<fwRemoval>" element in the
network status XML - it contains a serialized virFirewall object
that directly contains the commands necessary to remove the
firewall. I could instead just store "<firewall>", which would
include all the commands that were used to *create* the firewall in
addition to the commands needed to remove the firewall. The way it's
done currently takes up less space; switching to storing the full
firewall *might* be more informative to somebody, but on the other
hand would make the network status XML *very* long. If anybody has
an opinion about this, now is the time to bring it up - do you think
it's worth having a separate list of all the commands that were used
to create a network's firewall (keeping in mind that there is no
public API to access it)? Or is it enough to just store what's
needed to remove the firewall?
* Several months ago Eric Garver posted patches for a pure firewalld
backend, and I requested that they not be pushed because I wanted
that to be integrated with my nftables backend support. Due to the
fact that the firewalld backend is almost entirely implemented by
putting the bridge into a new firewalld "zone", with no individual
rules added, that won't happen as just another backend driver file
in parallel to iptables and nftables; it will instead work by
checking firewall_backend at a higher level in the network driver,
thus avoiding the calls to virNetfilterXXX() entirely. I have
locally merged Eric's patches over the top of these patches, and
there are surprisingly few conflicts, but since his patches didn't
account for a user-settable config (but instead just always used the
firewalld backend if firewalld was active), some of the patches are
going to require a bit of rework, which I'll take care of after
getting these patches in.

[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"}}'

[PATCH] Сheck snapshot disk is not NULL when searching it in the VM config
by Fima Shevrin
When creating a snapshot of a VM with multiple hard disks,
the snapshot takes into account the presence of all disks
in the system. If, over time, one of the disks is deleted,
the snapshot will continue to store knowledge of the deleted disk.
This results in the fact that at the moment of deleting the snapshot,
at the validation stage, a disk from the snapshot will be searched which
is not in the VM configuration. As a result, vmdisk variable will
be equal to NULL. Dereferencing a null pointer at the time of calling
virStorageSourceIsSameLocation(vmdisk->src, disk->src) will result in SIGSEGV.

[PATCH] network: add modify-or-add feature to net-update
by Abhiram Tilak
The current way of updating a network configuration uses `virsh
net-update` to add, delete or modify entries. But with such a mechansim
one should know if an entry with current info already exists. Adding
modify-or-add option automatically performs either modify or add
depending on the current state.

[PATCH 00/35] vsh: Fix handling of commands and help - part 3 (virsh testing overhaul)
by Peter Krempa
Part 3 was supposed to be the refactor of the command parser but since
I wanted to add few tests I've noticed that there's a lot of old cruft
and many tests are skipped.
This series refactors virshtest and optimizes it to run multiple
commands with one virsh instance. Doing this allows us to do more
testing in the same run time allowing us to reduce the amount of
"expensive" tests.
Further down this removes all of the 'shell' test infra which was used
for virsh.
Peter Krempa (35):
virshtest: Prepare for testing against output files
virshtest: Allow to test failure of commands
virshtest: Filter multiple occurences of string to drop in
testFilterLine
virshtest: Add support for testing commands read from input file and
adapt alias tests
virshtest: Adapt 'echo --split' tests to DO_TEST_SCRIPT
virshtest: Drop some redundant 'echo' cases
virshtest: Adapt some 'escaping' tests via DO_TEST_SCRIPT
vrishtest: Prepare for simpler testing - echo tests
virshtest: Test against output files ("echo" tests)
virshtest: Drop string form of expected output data of "echo" tests
virshtest: Replace list and nodeinfo tests by equivalent
VIR_TEST_SCRIPT variant
virshtest: Adapt tests for domain id lookup and state query to
DO_TEST_SCRIPT
virshtest: Adapt 'blkiotune' tests to DO_TEST_SCRIPT
virshtest: Adapt 'iothread' tests to DO_TEST_SCRIPT
virshtest: Drop support for testing against hardcoded strings
virshtest: Adapt argument parsing tests from 'virsh-optparse'
virshtest: Adapt 'snapshot-create-as' arg handling tests from
'virsh-optparse'
virshtest: Adapt numeric option arg handling tests from
'virsh-optparse'
virshtest: Adapt 'event' option arg handling tests from
'virsh-optparse'
virshtest: Reimplement 'virsh-output' test
qemuxmlconftest: Adapt XMLs from 'virsh-cpuset' and
'virsh-define-dev-segfault' cases
virshtest: Adapt 'virsh-vcpupin' test
virshtest: Adapt 'virsh-int-overflow'
virshtest: Adapt 'virsh-schedinfo'
virshtest: Adapt 'virsh-start' and 'virsh-undefine' tests as
'lifecycle' case
virsh: Fix '--name' and '--parent' used together in
'(snapshot|checkpoint)-list' command
vsh: Allow non-interactive use of 'cd' command
virshtest: Adapt 'virsh-snapshot' test
virshtest: Adapt 'virsh-checkpoint' test
virshtest: Adapt 'virsh-read-bufsiz' and 'virsh-read-non-seekable'
virshtest: Adapt 'libvirtd-pool'
tests: Re-implement '(virsh|virt-admin)-self-test' directly in meson
tests: Reimplement 'libvirtd-fail' case directly in meson
virshtest: Adapt virsh-uriprecedence test case
tests: Drop 'test-lib.sh'
