The script expects each of the symbols that it looks for to
be in one of three sections, which in nm(1) are described as
follows:
T - The symbol is in the text (code) section.
B - The symbol is in the BSS data section. This section
typically contains zero-initialized or uninitialized
data, although the exact behavior is system dependent.
D - The symbol is in the initialized data section.
When building on alpha, however, some of the symbols show up
in one of two additional sections, specifically:
S - The symbol is in an uninitialized or zero-initialized
data section for small objects.
G - The symbol is in an initialized data section for small
objects.
In other words, S is the same as B and G is the same as D,
except with some optimization for small objects that for some
reason is applied on alpha but not on other architectures.
I have confirmed that, for all the symbols that the script
complained about being missing on alpha, the section is the
expected one, that is, symbols that are reported as B on x86
are reported as S on alpha, and symbols that are reported as
D on x86 are reported as G on alpha.
Note that, while the B section doesn't seem to be used at all
on alpha, at least in our case, the D section still is.

The condition was completely wrong. As per the comment for function
virDomainMomentIsAncestor() it checks that the first argument is
descendant of the second argument.
Consider the following snapshot tree for VM:
s1
|
+- s2
| |
| +- s3
|
+- s4
|
+- s5 (current)
When deleting s2 with the original code we checked if
virDomainMomentIsAncestor(s2, s5) which would return false basically for
any snapshot as s5 is leaf snapshot so no children.
When deleting s2 with fixed code we check if
virDomainMomentIsAncestor(s5, s2) which still returns false but when
deleting s4 it will correctly return true.
Before this fix it fails with the following error:
error: Failed to delete snapshot s2
error: invalid argument: could not find base disk source in disk source chain
After the fix it fails with correct error:
error: Failed to delete snapshot s2
error: unsupported configuration: deletion of non-leaf external snapshot that is not in active chain is not supported

The current defaults, that can be altered on a per-architecture
basis, are derived from the historical x86 behavior.
Every time support for a new architecture is added to libvirt,
care must be taken to override these default: if that doesn't
happen, guests will end up with additional hardware, which is
something that's generally undesirable.
Turn things around, and require architectures to explicitly
ask for the devices to be created by default instead. The

We currently have a single test case called "minimal", which
suffers from two big flaws:
* it's limited to the x86_64/pc machine type;
* it explicitly enables a number of devices.
Add several test cases, one for each of the architectures and
machine types that we have good support for.
Unlike the existing one, they're *really* minimal: no devices
or controllers at all are present in the input XML. So the new
test cases demonstrate exactly what devices and controller
libvirt will decide to add automatically.

allocate memory and call the API second time). IOW - the usual,
old style of APIs where we didn't want to allocate memory on
caller's behalf. But because of this bug, a negative one is

There are a number of cases in which we want to test both the
normal behavior and the ABI_UPDATE behavior for the same input
XML.
The way this is currently implemented is ad-hoc, and involves
symlinking the input XML as well as coming up with an
alternative name for the ABI_UPDATE variant: in most cases the
-abi-update suffix is added, but since this is not enforced
there are a couple of cases where we do something else instead.
To make things simpler and more consistent, implement the
naming convention at the macro level. This way, we no longer
need to create any symlinks for the input file, and the output

Encryption secrets are considered a format dependency, even
when being used by the storage node itself, as in the case of
using encryption engine=librbd.
Currently, the storage node is created (blockdev-add) before
creating the format dependencies (including encryption secrets).
As a result, when trying to perform a blockcopy when the target
disk uses librbd encryption, an error of this form is returned:
"error: internal error: unable to execute QEMU command 'blockdev-add': No secret with id 'libvirt-5-format-encryption-secret0'"
To overcome this error, we change the order of commands so that
format dependencies are created BEFORE creating the storage node.

After v9.1.0-rc1~116 we track whether it's us who created a
macvtap or not. But when updating a vNIC its definition might be
replaced with a new one (though, ifname is not allowed to
change), e.g. to reflect new QoS, link state, etc.
Now, the fact whether we created macvtap for given vNIC is stored
in net->privateData->created. And replacing definition is done by
simply freeing the old definition and making the pointer point to
the new one. But this does not preserve the 'created' flag, which
in turn means when a domain is shutting off, the macvtap is not
removed (see loop inside of qemuProcessStop()).
Copy this flag into new definition and leave a note in
_qemuDomainNetworkPrivate struct.

After guest is started, or we are reconnecting to already running
one (after daemon restart), qemuProcessRefreshRxFilters() is
called to refresh rx-filters (basically MAC addresses of guest
NICs) as they might have changed while we were not running (for
the case when reconnecting to an already running guest), or we
need to enable them by running a command (for freshly started
guest - see processNicRxFilterChangedEvent()).
Now, our XML parser allowed trustGuestRxFilters attribute for all
types and models of <interface/> while in reality, only virtio
model AND TUN/TAP based types can see MAC address changes. For
other combinations, QEMU reports an error.
This all means that when the daemon is restarted and it
reconnects to a guest with, well invalid configuration, or when
such guest is restored from a saved image, or migrated then we
issue the monitor command, to which QEMU replies with an error
which is then propagated to users:
error: internal error: unable to execute QEMU command 'query-rx-filter': invalid net client name: hostdev0
While on one hand users should fix their configuration (and after
v10.0.0-rc1~123 they can do that even on live domains), libvirt
can also has some logic built in that prevent issuing the command
in the first place (for obviously wrong cases).
