Commit c7151b0 added the completion for VSH_OT_INT options, say '--cellno'
and '--pagesize', So we need to ignore VSH_OT_INT otherwise we get the
incorrect completion.
before:
# virsh freepages --pagesize <TAB><TAB>
--all --cellno 1GiB 2MiB 4KiB
after:
# virsh freepages --pagesize <TAB><TAB>
1GiB 2MiB 4KiB

When a list is freed, we iterate through all the items, invoking the
free function for each; the actual free function called for each element
is the function of the actual type of each element, and thus the @_next
pointer in the element struct has the same type as the element itself.
Currently, the free function gets the parent of the current element
type, and invoke its free function to continue freeing the list.
However, in case the hierarchy of the classes has more than 1 level
(i.e. Class <- SubClass <- SubSubClass), the invoked free function is
only the parent class' one, and not the actual base class of the
hierarchy.
To fix that, change the generator to get the base class of a class, and
invoking that instead. Also, avoid to set the @_next back, as it is not
needed.
Fixes commits 5cff36e39a and
f76c6dde2e.

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,
This is redundant for a shutoff domain.
# virsh domstate $GUEST

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

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().
