Regular VM shutdown triggers the error for existing session of virsh
console and it returns with non-zero exit code:
error: internal error: console stream EOF
The message and status code are misleading because there's no real
error. virStreamRecv returns 0 correctly when EOF is reached.
Existing implementations of esx, fd, and remote streams behave the same
for virStreamFinish and virStreamAbort: they close the stream. So, we
can continue to use virStreamAbort to handle EOF and errors from
virStreamRecv but additonally we can report error if virStreamAbort
fails.

It may happen that we leave some XATTRs behind. For instance, on
a sudden power loss, the host just shuts down without calling
restore on domain paths. This creates a problem, because when the
host starts up again, the XATTRs are there but they don't reflect
the true state and this may result in libvirt denying start of a
domain.
To solve this, save a unique timestamp (host boot time) among

The AM_CPPFLAGS setting includes the gnulib headers, which
means we can get some replacement functions defined. Since
virt-login-shell and the NSS module intentionally don't link
to gnulib, these replacement functions causes link failures.
This was seen cross-compiling on Debian for example:
virt-login-shell.o: In function `main':
/builds/libvirt/libvirt/build/tools/../../tools/virt-login-shell.c:81: undefined reference to `rpl_strerror'
/builds/libvirt/libvirt/build/tools/../../tools/virt-login-shell.c:66: undefined reference to `rpl_strerror'
/builds/libvirt/libvirt/build/tools/../../tools/virt-login-shell.c:75: undefined reference to `rpl_strerror'
The only way to avoid these replacement gnulib headers is
to drop the -Ignulib/lib flags. We do still want to use
gnulib for configmake.h and intprops.h, but those can be
included via their full path.
We must also stop using internal.h, since that expects
-Ignulib/lib to be on the include path in order to resolve

The virt-login-shell binary is a setuid program that takes
no arguments. When invoked it looks at the invoking uid,
resolves it to a username, and finds an LXC guest with the
same name. It then starts the guest and runs the shell in
side the namespaces of the container.
Given this set of tasks the virt-login-shell binary needs
to connect to libvirtd, make various other libvirt API calls.
This is a problem for setuid binaries as various libraries
that libvirt.so links to are not safe. For example, they have
constructor functions which execute an unknown amount of code
that can be influenced by env variables.
For this reason virt-login-shell doesn't use libvirt.so,
but instead links to a custom, cut down, set of source files
sufficient to be a local client only.
This introduces a problem for integrating glib2 into libvirt
though, as once integrated, there would be no way to build
virt-login-shell without an external dependancy on glib2 and
this is definitely not setuid safe.
To resolve this problem, we split the virt-login-shell binary
into two parts. The first part is setuid and does almost
nothing. It simply records the original uid+gid, and then
invokes the virt-login-shell-helper binary. Crucially when
it does this it completes scrubs all environment variables.
It is thus safe for virt-login-shell-helper to link to the
normal libvirt.so. Any things that constructor functions
do cannot be influenced by user control env vars or cli
args.

Introduce a bunch of new virsh commands for managing checkpoints in

after virsh-snapshot.c. There is no need for checkpoint-revert or
checkpoint-current since those snapshot APIs have no checkpoint
counterpart. Similarly, it is not necessary to change which
checkpoint is current when redefining from XML, since until we
integrate checkpoints with snapshots, there is only a linear chain
(and you can deduce the current checkpoint by instead using
'checkpoint-list --leaves'). Other aspects of checkpoint-list are
also a bit simpler than the snapshot counterpart, in part because we
don't have to cater to back-compat to older API.
Upcoming patches will test these interfaces once the test driver

Ideally, a software that's translating domain names would iterate
over all addresses the NSS returned, but some software does not
bother (e.g. ping). What happens is that for instance when
installing a guest, it's assigned one IP address but once it's
installed and rebooted it gets a different IP address (because
client ID used for the first DHCP traffic when installing the
guest was generated dynamically and never saved so after reboot
the guest generated new ID which resulted in different IP address
to be assigned). This results in 'ping $domain' not working
properly as it still pings the old IP address. Well, it might -
NSS plugin does not guarantee any order of addresses.
To resolve this problem, we can sort the array just before
returning it to the caller (ping) so that the newer IP addresses

We've been doing a terrible job of performing XML validation in our

with domains back in commit dd69a14f, v1.2.12, but didn't catch all
domain-related APIs, didn't document the use of the flag, and didn't
cover other XML). New APIs (like checkpoints) should do the validation
unconditionally, but it doesn't hurt to continue retrofitting existing
APIs to at least allow the option.
While there are many APIs that could be improved, this patch focuses
on wiring up a new snapshot XML creation flag through all the
hypervisors that support snapshots, as well as exposing it in 'virsh
snapshot-create'. For 'virsh snapshot-create-as', we blindly set the
flag without a command-line option, since the XML we create from the
command line should generally always comply (note that validation
might cause failures where it used to succeed, such as if we tighten
the RNG to reject a name of '../\n'); but blindly passing the flag
means we also have to add in fallback code to disable validation if
the server is too old to understand the flag.

virsh snapshot-create-as supports 'file' storage type in --diskspec by default.
But it doesn't support 'block' storage type in the virshParseSnapshotDiskspec().
So if a snapshot on a block device (e.g. LV) was created, the type of
current running storage source in dumpxml is inconsistent with the actual
backend storage source. It will check file-system type mismatch failed
and return an error message of 'Migration without shared storage is unsafe'
when VM performs a live migration after this snapshot.
Considering virsh has to be able to work remotely that recognizing a block device
by prefix /dev/ or by stat() may be not suitable, so adding a "stype" field
for the --diskspec string which will be either "file" or "block".

stat-htlb-pgalloc represents the number of successful hugetlb page allocations
while stat-htlb-pgfail represents the number of failed ones. Add this
statistics reporting to libvirt.
To enable this feature for vm, guest kenel >= 4.17 is required because
the exporting hugetlb page allocation for virtio balloon is introduced
since 6c64fe7f.

If the console was disconnected due to a connection problem or a problem on the
server side it is convinient to provide the cause to the user. If the error
come from the API then the error is saved in a virsh global variable. However,
since success is returned from virshRunConsole after we reach the waiting stage,
then the error is never reported. Let's track the error in the event loop.
Next after failure we do a cleanup and this cleanup can overwrite
root cause. Thus let's save root cause immediately and then set it to
virsh error after all cleanup is done.
Since we'll be sending the error to the consumer, each failure path from
the event handlers needs to be augmented to provide what error generated

that starts with # as a comment which silently eats all remaining
arguments to the next newline or semicolon.
Note that batch mode recognizes unquoted # at the start of any word as
a command as part of the tokenizer, while this patch only treats # at
the start of the command word as a comment (any other # remaining by
the time vshCommandParse() is processing things was already quoted
during the tokenzier, and as such was probably intended as the actual
argument to the command word earlier in the line).

For snapshots, virsh already has a (shockingly naive [1]) client-side
topological sorter with the --tree option. But as a series of REDEFINE
calls must be presented in topological order, it's worth letting the
server do the work for us, especially since the server can give us a
topological sorting with less effort than our naive client
reconstruction.
[1] The XXX comment in virshSnapshotListCollect() about --tree being
O(n^3) is telling; https://en.wikipedia.org/wiki/Topological_sorting
is an interesting resource describing Kahn's algorithm and other
approaches for O(n) topological sorting for anyone motivated to use a
more elegant algorithm than brute force - but that doesn't affect this
patch.
For now, I am purposefully NOT implementing virsh fallback code to
provide a topological sort when the flag was rejected as unsupported;
we can worry about that down the road if users actually demonstrate
that they use new virsh but old libvirt to even need the fallback.
(The code we use for --tree could be repurposed to be such a fallback,
whether or not we keep it naive or improve it to be faster - but
again, no one should spend time on a fallback without evidence that we
need it.)
The test driver makes it easy to test:
$ virsh -c test:///default '
snapshot-create-as test a
snapshot-create-as test c
snapshot-create-as test b
snapshot-list test
snapshot-list test --topological
snapshot-list test --descendants a
snapshot-list test --descendants a --topological
snapshot-list test --tree
snapshot-list test --tree --topological
'
Without any flags, virsh does client-side sorting alphabetically, and
lists 'b' before 'c' (even though 'c' is the parent of 'b'); with the
flag, virsh skips sorting, and you can now see that the server handed
back data in a correct ordering. As shown here with a simple linear
chain, there isn't any other possible ordering, so --tree mode doesn't
seem to care whether --topological is used. But it is possible to
compose more complicated DAGs with multiple children to a parent
(representing reverting back to a snapshot then creating more
snapshots along those divergent execution timelines), where it is then
possible (but not guaranteed) that adding the --topological flag
changes the --tree output (the client-side --tree algorithm breaks
ties based on alphabetical sorting between two nodes that share the
same parent, while the --topological sort skips the client-side
alphabetical sort and ends up exposing the server's internal order for
siblings, whether that be historical creation order or dependent on a
random hash seed). But even if the results differ, they will still be
topologically correct.
