The original motivation for adding virNetDevIPCheckIPv6Forwarding
(commit 00d28a78b5) was that networking routes would disappear when
ipv6 forwarding was enabled for an interface.
This is a fairly undocumented side-effect of the "accept_ra" sysctl
for an interface. 1 means the interface will accept_ra's if not
forwarding, 2 means always accept_RAs; but it is not explained that
enabling forwarding when accept_ra==1 will also clear any kernel RA
assigned routes, very likely breaking your networking.
The check to warn about this currently uses netlink to go through all
the routes and then look at the accept_ra status of the interfaces.
However, it has been noticed that this problem does not affect systems
where IPv6 RA configuration is handled in userspace, e.g. via tools
such as NetworkManager. In this case, the error message from libvirt
is spurious, and modifying the forwarding state will not affect the RA
state or disable your networking.
If you refer to the function rt6_purge_dflt_routers() in the kernel,
we can see that the routes being purged are only those with the
kernel's RTF_ADDRCONF flag set; that is, routes added by the kernel's
RA handling. Why does it do this? I think this is a Linux
implementation decision; it has always been like that and there are
some comments suggesting that it is because a router should be
statically configured, rather than accepting external configurations.
The solution implemented here is to convert the existing check into a
walk of /proc/net/ipv6_route (because RTF_ADDRCONF is apparently not
exposed in netlink) and look for routes with this flag set. We then
check the accept_ra status for the interface, and if enabling
forwarding would break things raise an error.
This should hopefully avoid "interactive" users, who are likely to be
using NetworkManager and the like, having false warnings when enabling
IPv6, but retain the error check for users relying on kernel-based
IPv6 interface auto-configuration.

While we set up perf events for a shutoff domain and check the settings,
All of perf events are reported as 'disabled', unless we add --config,

Use virDomainObjGetOneDefState instead of virDomainObjGetOneDef to fix
the issue. After patch, The perf event status of a shutoff domain is

In v6.7.0-rc1~86 I've tried to fix a problem where we were not
detecting NUMA nodes properly because we misused behaviour of a
libnuma API and as it turned out the behaviour was correct for
hosts with 64 CPUs in one NUMA node. So I changed the code to use
nodemask_isset(&numa_all_nodes, ..) instead and it fixed the
problem on such hosts. However, what I did not realize is that
numa_all_nodes does not reflect all NUMA nodes visible to
userspace, it contains only those nodes that the process
(libvirtd) an allocate memory from, which can be only a subset of
all NUMA nodes. The bitmask that contains all NUMA nodes visible
to userspace and which one I should have used is: numa_nodes_ptr.
For curious ones:
4a22f22382
And as I was fixing virNumaGetNodeCPUs() I came to realize that
we already have a function that wraps the correct bitmask:
virNumaNodeIsAvailable().

0f7436ca54 added code during virtual network startup to wait for DAD
(Duplicate Address Detection) to complete if there were any IPv6
addresses on the network. This wait was needed because (according to
the commit log) "created problems when [the "dummy" tap device] is set
to IFF_DOWN prior to DAD completing".
That commit in turn referenced commit db488c7917, which had added the
code to set the dummy tap device IFF_DOWN, commenting "DAD has
happened (dnsmasq waits for it)", and in its commit message pointed
out that if we just got rid of the dummy tap device this wouldn't be
needed.
Now that the dummy tap device has indeed been removed (commit
ee6c936fbb), there is no longer any need to set it IFF_DOWN, and thus
nothing requiring us to wait for DAD to complete. At any rate, with
the dummy tap device removed, leaving nothing else on the bridge when
it is first started, DAD never completes, leading to failure to start
any IPv6 network.
So, yes, this patch removes the wait for DAD completion, and IPv6
networks can once again start, and their associated dnsmasq process
starts successfully (this is the problem that the DAD wait was
originally intended to fix)
