Error : virHostCPUGetKVMMaxVCPUs:1228 : KVM is not supported on this platform: Function not implemented.

Hello.
I'm running Debian bookworm on my ARM Chromebook,model "xe303c12" and
I've recompiled the kernel (5.4) to enable KVM,so now my system sounds like
this :

I have installed libvirt 9.7.0,qemu 5.1 and virt-manager from source
code with the final goal to be able to connect qemu,kvm and libvirt
together to virtualize FreeBSD 13.2 for arm 32 bit.

Thanks Jirka, I expected "autofree" attribute to be carried to "tmp" in the calling method,
which would be freed when tmp goes out of scope. So, I implemented it this way.
With some experimentation, I confirmed the correct behavior.
I will fix this in my next version.

[PATCH] manpage: virsh: Note that 'virsh undefine --remove-all-storage' doesn't remove backing images
by Peter Krempa
Removing a backing image could break other image chains as it's
theoretically possible to share backing chains.
As --storage/--remove-all-storage is fully implemented in virsh as a
helper option, which enumerates and deletes VM's volumes. We do not plan
to make it any more complicated.
Document that backing chains are not removed.

[PATCH] virsh-snapshot: Avoid passing NULL to qsort() in virshSnapshotListCollect()
by Michal Privoznik
If a domain has no snapshots and 'virsh snapshot-list' is called,
this gets all the way down to virshSnapshotListCollect() which
then collects all snapshots (none), and passes them to qsort()
which doesn't like being called with NULL:
extern void qsort (void *__base, size_t __nmemb, size_t __size,
__compar_fn_t __compar) __nonnull ((1, 4));

[PATCH Libvirt v3 00/10] Support dirty page rate upper limit
by ~hyman
Hi, This is the latest version for the series, please review.
Thanks,
Yong
v3:
- rebase on master and fix conflicts
- refactor the comments and update the version tag
v2:
The patch set introduce a new API virDomainSetVcpuDirtyLimit to
allow upper Apps to set upper limits of dirty page rate for virtual
CPUs, the corresponding virsh API as follows:
limit-dirty-page-rate <domain> <rate> [--vcpu <number>] \
[--config] [--live] [--current]
We put the dirty limit persistent info with the "vcpus" element in
domain XML and extend dirtylimit statistics for domGetStats:
<domain>
...
<vcpu current='2'>3</vcpu>
<vcpus>
<vcpu id='0' hotpluggable='no' dirty_limit='10' order='1'.../>
<vcpu id='1' hotpluggable='yes' dirty_limit='10' order='2'.../>
</vcpus>
...
</domain>
If --vcpu option is not passed in the virsh command, set all virtual
CPUs; if rate is set to zero, cancel the upper limit.
Examples:
To set the dirty page rate upper limit 10 MB/s for all virtual CPUs in
c81_node1, use:
# virsh limit-dirty-page-rate c81_node1 --rate 10 --live
Set dirty page rate limit 10(MB/s) for all virtual CPUs successfully
# virsh dumpxml c81_node1 | grep dirty_limit
<vcpu id='0' enabled='yes' hotpluggable='no' order='1'
dirty_limit='10'/>
<vcpu id='1' enabled='yes' hotpluggable='no' order='2'
dirty_limit='10'/>
<vcpu id='2' enabled='yes' hotpluggable='no' order='3'
dirty_limit='10'/>
<vcpu id='3' enabled='no' hotpluggable='yes' dirty_limit='10'/>
<vcpu id='4' enabled='no' hotpluggable='yes' dirty_limit='10'/>
......
Query the dirty limit info dynamically:
# virsh domstats c81_node1 --dirtylimit
Domain: 'c81_node1'
dirtylimit.vcpu.0.limit=10
dirtylimit.vcpu.0.current=0
dirtylimit.vcpu.1.limit=10
dirtylimit.vcpu.1.current=0
dirtylimit.vcpu.2.limit=10
dirtylimit.vcpu.2.current=0
dirtylimit.vcpu.3.limit=10
dirtylimit.vcpu.3.current=0
dirtylimit.vcpu.4.limit=10
dirtylimit.vcpu.4.current=0
......
To cancel the upper limit, use:
# virsh limit-dirty-page-rate c81_node1 --rate 0 --live
Cancel dirty page rate limit for all virtual CPUs successfully
# virsh dumpxml c81_node1 | grep dirty_limit
# virsh domstats c81_node1 --dirtylimit
Domain: 'c81_node1'
The dirty limit uses the QEMU dirty-limit feature introduced since
7.1.0, this feature allows CPU to be throttled as needed to keep
their dirty page rate within the limit. It could, in some scenes, be
used to provide quality-of-service in the aspect of the memory
workload for virtual CPUs and QEMU itself use the feature to
implement the dirty-limit throttle algorithm and apply it on the
live migration, which improve responsiveness of large guests
during live migration and can result in more stable read
performance. The other application scenarios remain
unexplored, before that, Libvirt could provide the basic API.
Hyman Huang(黄勇) (10):
qemu_capabilities: Introduce QEMU_CAPS_VCPU_DIRTY_LIMIT capability
conf: Introduce XML for dirty limit configuration
libvirt: Add virDomainSetVcpuDirtyLimit API
qemu_driver: Implement qemuDomainSetVcpuDirtyLimit
domain_validate: Export virDomainDefHasDirtyLimitStartupVcpus symbol
qemu_process: Setup dirty limit after launching VM
virsh: Introduce limit-dirty-page-rate api
qemu_monitor: Implement qemuMonitorQueryVcpuDirtyLimit
qemu_driver: Extend dirtlimit statistics for domGetStats
virsh: Introduce command 'virsh domstats --dirtylimit'
