[libvirt] [PATCH] Fix python error reporting for some storage operations
by Cole Robinson
In the python bindings, all vir* classes expect to be
passed a virConnect object when instantiated. Before
the storage stuff, these classes were only instantiated
in virConnect methods, so the generator is hardcoded to
pass 'self' as the connection instance to these classes.
Problem is there are some methods that return pool or vol
instances which aren't called from virConnect: you can
lookup a storage volume's associated pool, and can lookup
volumes from a pool. In these cases passing 'self' doesn't
give the vir* instance a connection, so when it comes time
to raise an exception crap hits the fan.
Rather than rework the generator to accomodate this edge
case, I just fixed the init functions for virStorage* to
pull the associated connection out of the passed value
if it's not a virConnect instance.
Thanks,
Cole

[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] Extend libvirt-guests to shutdown only persistent VMs
by Benjamin Taubmann
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

[PATCH v3 00/12] Improve versioned CPU support in libvirt
by Jonathon Jongsma
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
cpu_map: Add versioned Dhyana CPUs

[libvirt PATCH 00/12] Add vmx-* features from qemu
by Tim Wiederhake
For rationale, see patch 3 (cpu_map: No longer ignore vmx- features in
sync_qemu_features_i386.py).
Adding features in bunches (one patch per msr index), as this series
is adding ~100 features.
This also adds cpu features "gds-no" and "amx-complex" and brings
libvirt in sync with qemu commit ad6ef0a42e.

[PATCH 0/4] vmx: A couple of disk related fixes
by Michal Privoznik
The first patch fixes an issue.
The last one - I am not sure if it's not going to break something and
thus it's optional.

vmx: Accept empty fileName for cdrom-image
vmx2xmltest: Add another test case
vmx: Separate disk target name generation into a function
vmx: Ensure unique disk targets when parsing

[v3 0/4] Support for dirty-limit live migration
by Hyman Huang
v3:
- adjust the parameter check location for suggested by Michal
- mark the VIR_MIGRATE_DIRTY_LIMIT flag since 10.0.0
- rebase on master
Thanks Michal for the comments.
Please review,
Yong.
v1:
The dirty-limit functionality for live migration was
introduced since qemu>=8.1.
In the live migration scenario, it implements the force
convergence using the dirty-limit approach, which results
in better reliable read performance.
A straightforward dirty-limit capability for live migration
is added by this patchset. Users might not care about other
dirty-limit arguments like "x-vcpu-dirty-limit-period"
or "vcpu-dirty-limit," thus do not expose them to Libvirt
and Keep the default configurations and values in place.
For more details about dirty-limit, please see the following
reference:
https://lore.kernel.org/qemu-
devel/169024923116.19090.10825599068950039132-0(a)git.sr.ht/
Hyman Huang (4):
Add VIR_MIGRATE_DIRTY_LIMIT flag
qemu_migration: Implement VIR_MIGRATE_DIRTY_LIMIT flag
virsh: Add support for VIR_MIGRATE_DIRTY_LIMIT flag

[PATCH rfcv3 00/11] 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], there are TDX spec links and public repository link at github
for each software component.
This patchset is another software component to extend libvirt to support TDX,
with which one can start a VM 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 add a new way to emulate the reset for TDX guest,
called "hard reboot". We achieve this by killing old qemu and start a new one.
Complete code can be found at [1], matching qemu code can be found at [2].
There are some new properties for tdx-guest object, i.e. `mrconfigid`, `mrowner`,
`mrownerconfig` and `debug` which aren't in matching qemu[2] yet. I keep them
intentionally as they will be implemented in qemu as extention series of [2].
* 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 1-3: Support query of TDX capabilities.
- patch 4-6: Add TDX type to launchsecurity framework.
- patch 7-11: Add hard reboot support to TDX guest
