64f26276bf virsh: vcpuinfo: Report vcpu number from the structure rather than it's position
virVcpuInfo contains the vcpu number that the data refers to. Report
what's returned by the daemon rather than the sequence number as with
sparse vcpu topologies they won't match.

a144f28467 virsh: avoid i18n puzzle
Use the full versions of the message, instead of composing a base
message with what was updated; the change makes the messages properly
translatable, since different parts of a sentence might need different

b620bdee14 virsh: respect -q/--quiet more
Turn various vshPrint() informative messages into vshPrintExtra(), so
they are not printed when requesting the quiet mode; neither XML/info
outputs nor the results of commands are affected.
Also change the expected outputs of the virsh-undefine test, since virsh
is invoked in quiet mode there.

Some informative messages might still be converted (and thus silenced
when in quiet mode), but this is an improvements nonetheless.

18701e9d62 virsh: Fix core for cmdSecretGetValue
https://bugzilla.redhat.com/show_bug.cgi?id=1366611

When commit id 'cb2e3e50' reworked the cmdSecretGetValue call to use
VIR_DISPOSE_STRING for base64, it neglected to initialize the base64
value to NULL since the cleanup: label could be reached prior to the
base64 value being set or not.  This resulted in a core dump, adding
the initialization will avoid the issue.

4914494eb8 virt-admin: Fix the error when an invalid URI has been provided
After commit 9d479dd1 fiddled with the cmdConnect's output which used to be a
bit more verbose prior to the mentioned commit, the program flow would result
in a quite confusing error if an invalid URI has been provided:

    error: Failed to connect to the admin server
    Connected to the admin server
    error: <some error>

The problem is that the commit mentioned above relied on the fact that
connect routine always succeeds which is not true.

2197ea56d7 conf: Add IOThread quota and period scheduler/cputune defs
https://bugzilla.redhat.com/show_bug.cgi?id=1356937

Add the definitions to allow for viewing/setting cgroup period and quota
limits for IOThreads.

This is similar to the work done for emulator quota and period by
commit ids 'b65dafa' and 'e051c482'.

Being able to view/set the IOThread specific values is related to more
recent changes adding global period (commmit id '4d92d58f') and global
quota (commit id '55ecdae') definitions and qemu support (commit id
'4e17ff79' and 'fbcbd1b2'). With a global setting though, if somehow
the IOThread value in the cgroup hierarchy was set "outside of libvirt"
to a value that is incompatible with the global value.

Allowing control over IOThread specific values provides the capability
to alter the IOThread values as necessary.

f5f32bcd1b admin: Fix default uri config option name s/admin_uri_default/uri_default
The original name 'admin_uri_default' was introduced to our code by commit
dbecb87f. However, at that time we already had a separate config file for
admin library but the commit mentioned above didn't properly adjust the
config's option name. The result is that when we're loading the config, we
check a non-existent config option (there's not much to do with the URIs
anyway, since we only allow local connection). Additionally, virt-admin's man
page documents, that the default URI can be altered by setting
admin_uri_default option. So the fix proposed by this patch leaves the
libvirt-admin.conf as is and adjusts the naming in the code as well as in the
virt-admin's man page.

d02ef33451 tools: Make use of the correct environment variables
Since commit 834c5720 which extracted the generic functionality out of virsh
and made it available for other clients like virt-admin to make use of it, it
also introduced a bug when it renamed the original VIRSH_ environment variables
to VSH_ variables. Virt-admin of course suffers from the same bug, so this
patch modifies the generic module vsh.c to construct the correct name for
environment variables of each client from information it has.

0ef07e19c7 vsh: Make vshInitDebug return int instead of void
Well, the reason behind this change is that if the function is extended in some
way that e.g. would involve allocation we do not have a way of telling it to
the caller. More specifically, vshInitDebug only relies on some hardcoded
environment variables (by a mistake) that aren't documented anywhere so neither
virsh's nor virt-admin's documented environment variables take effect. One
possible solution would be duplicate the code for each CLI client or leave the
method be generic and provide means that it could figure out, which client
called it, thus initializing the proper environment variables but that could
involve operations that might as well fail in certain circumstances and the
caller should know that an error occurred.

res is assigned one of two results based on a pair of if then else if

   cpuinfo flags (x86, s390)
2) test for /dev/kvm also on platforms where no cpu flags are set

Finally Add a more generic error hint message for non-x86 plaforms
when /dev/kvm is missing.

18a10ddc16 virt-login-shell: add ability to auto-detect shell from container
Currently the shell must be looked up from the config setting in
/etc/libvirt/virt-login-shell.conf. This is inflexible if there
are containers where different users need different shells. Add
add a new 'auto-shell' config parameter which instructs us to
query the containers' /etc/passwd for the shell to be exec'd.

ee877b8710 virt-login-shell: fully reset container environment
The virt-login-shell environment will be initialized with
an arbitrary number of environment variables determined
by the SSH daemon and PAM configuration. Most of these are
not relevant inside the container, and at best they are
noise and at worst they'll break apps. For example if
XDG_RUNTIME_DIR is leaked to the container, it'll break
any apps using it, since  the directory it points to is
only visible to the host OS filesystem, not the container
FS.

Use clearenv() to blank out everything and then set known
good values for PATH, SHELL, USER, LOGNAME HOME and TERM.
Everything else is left up to the login shell to initialize.

8a95d3df48 virt-login-shell: change way we request a login shell
Currently we request a login shell by passing the -l argument
to the shell. This is either hardcoded, or required to be
specified by the user in the virt-login-shell.conf file.

The standard way for login programs to request a shell run
as a login shell is to modify the argv passed to execve()
so that argv[0] contains the relative shell filename
prefixed with a zero. eg instead of doing

  const char **shellargs = ["/bin/bash", "-l", NULL];
  execve(shellargs[0], shellargs, env);

We should be doing

  const char **shellargs = ["-bash", NULL];
  execve("/bin/bash", shellargs, env);

da7396605b virt-login-shell: honour the -c option to launch commands
The virt-login-shell program is supposed to look like a
regular shell to clients. Login services like sshd
expect the shell to accept a '-c cmdstring' argument to
specify a command to launch instead of presenting an
interactive prompt.

We can implement this by simply passing the '-c cmdstring'
data straight through to the real shell we use. This does
not open any security holes, since the command is not run
until we're inside the container namespaces. This allows
scp to work for users with virt-login-shell.

0c56d94318 tools: Fix connect command
The man page says: "(Re)-Connect to the hypervisor. When the shell is
first started, this is automatically run with the URI parameter
requested by the "-c" option on the command line."  However, if you run:

  virsh -c 'test://default' 'connect; uri'

the output will not be 'test://default'.  That's because the 'connect'
command does not care about any virsh-only related settings and if it is
run without parameters, it connects with @uri == NULL.  Not only that
doesn't comply to what the man page describes, but it also doesn't make
sense.  It also means you aren't able to reconnect to whatever you are
connected currently.

So let's fix that in both virsh and virt-admin add a test case for it.

f854c559b9 host-validate: Be more careful when checking for cgroup mounts
The existing code is built on the assumption that no cgroup
name can appear as part of another cgroup name; moreover, cgroups
are expected to always be listed in a specific order.

If that's not the case, eg. 'cpuacct' is listed before 'cpu', the
algorithm fails to detect the cgroup mount point.

Rewrite it to get rid of such assumptions.

c661b675f1 host-validate: Improve CPU flags processing
Instead of relying on substring search, tokenize the input
and process each CPU flag separately. This ensures CPU flag
detection will continue to work correctly even if we start
looking for CPU flags whose name might appear as part of
other CPU flags' names.

The result of processing is stored in a virBitmap, which
means we don't have to parse /proc/cpuinfo in its entirety
for each single CPU flag we want to check.

Moreover, use of the newly-introduced virHostValidateCPUFlag
enumeration ensures we don't go looking for random CPU flags
which might actually be simple typos.

VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY and VIR_DOMAIN_PAUSED_POSTCOPY are
used on the source host once migration enters post-copy mode (which
means the domain gets paused on the source. After the destination host
takes over the execution of the domain, its virtual CPUs are resumed and
the domain enters VIR_DOMAIN_RUNNING_POSTCOPY state and
VIR_DOMAIN_EVENT_RESUMED_POSTCOPY event is emitted.

In case migration fails during post-copy mode and none of the hosts have
complete state of the domain, both domains will remain paused with
VIR_DOMAIN_PAUSED_POSTCOPY_FAILED reason and an upper layer may decide
what to do.

When the login session doesn't have an ssh -X type display agent in
order for libvirtd to run the polkit session authentication, attempts
to run 'virsh -c qemu:///system list' from an unauthorized user (or one
that isn't part of the libvirt /etc/group) will fail with the following
error from libvirtd:

error: authentication unavailable: no polkit agent available to
       authenticate action 'org.libvirt.unix.manage'

In order to handle the local authentication, we will use the new
virPolkitAgentCreate API in order to create a text based authentication
agent for our non readonly session to authenticate with.

The new code will execute in a loop allowing 5 failures to authenticate
before failing out.

Since the code is changing the source image path by modifying the

As <backingStore> is relevant to the <source> part of the image, the
update of that part makes the element invalid.

CD/floppy images usually don't have a backing chain and the element is
currently ignored though but it might start being used in the future so
let's start behaving correctly.

Drop the <backingStore> subtree once we want to update the XML.

Before this patch, you'd get:
$ virsh change-media --eject --print-xml 10 hdc
<disk type="file" device="cdrom">

After a block job hits 100%, we only need to apply a timeout waiting for

If neither callback could be registered, there's clearly no need for a
timeout.

If both callbacks were registered, then we're guaranteed to eventually
get one of the events. The path being used by virsh must be exactly the
source path or target device in the domain's disk definition, and these
are the respective strings sent back in these two events.

63cdc92f04 storage: Add TRIM algorithm to storage volume API
This new algorithm adds support for wiping volumes using TRIM.

It does not overwrite all the data in a volume, but it tells the
backing storage pool/driver that all bytes in a volume can be
discarded.

It depends on the backing storage pool how this is handled.

A SCSI backend might send UNMAP commands to remove all data present
on a LUN.

A Ceph backend might use rbd_discard() to instruct the Ceph cluster
that all data on that RBD volume can be discarded.

985f01a65f virsh: fix cpu-stats command output format issue
After commit 57177f1, the cpu-stats command format change to:

CPU0:
    cpu_time         14401.507878990 seconds
    vcpu_time    14378732785511

vcpu_time is not user friendly. After this patch, it will
change back:
CPU0:
    cpu_time         14401.507878990 seconds
    vcpu_time        14378.732785511 seconds

a2e80549a2 virsh: cpu-stats: Remove unneeded flags
virDomainGetCPUStats doesn't support flags so there's no need to carry
the 'flags' variable around. Additionally since the API is poorly
designed I doubt that it will be extended.

99f8fb4c55 virt-host-validate: Fix error level for user namespace check
From the code it seems to me that we need user namespace if
configured in domain XML. Otherwise we don't use it at all.
However our tool is more strict about that. Fix this discrepancy.

d55e11a302 virt-host-validate: Check those CGroups that we actually use
Since the introduction of virt-host-validate tool the set of
cgroup controllers we use has changed so the tool is checking for
some cgroups that we don't need (e.g. net_cls, although I doubt
we have ever used that one) and is not checking for those we
actually use (e.g. cpuset).

9cbd1ecc3e virsh: Correctly detect inserted media in change-media command
https://bugzilla.redhat.com/show_bug.cgi?id=1250331

It all works like this. The change-media command dumps domain
XML, finds the corresponding cdrom device we want to change media
in and returns it in the xmlNodePtr form. This way we don't have
to bother with keeping all the subelements or attributes that we
don't care about in the XML that is fed back to libvirt for the
update API.

Now, the problem is we try to be clever here and detect if disk
already has a source (indicated by <source/> subelement).
However, bare fact that the element is there does not mean disk
has source. Make our clever check better.

3bd2ee5d55 virsh: Don't fetch status for all domains in cmdList
We are getting the list of domains and after that we iterate over
the list and try to get status for each domain hoping it will
skip over domains that disappeared meanwhile. However, this
solution to race is bogus - domain may disappear right after we
have checked its state and before we exec another API over it
(e.g. virDomainHasManagedSaveImage()). Also, when printing just
names or uuids (list --name / --uuid) we issue APIs to obtain the
values, however these require no RPC call as all requested info
is in virDomain object that client already has.
Therefore move the status obtaining only to the place that really
needs it.

f99f79e380 wireshark: Drop DESTDIR from install path
In 50078cfbcb I've tried to fix distcheck but accidentally
broke rpm build. The problem is that rpm build not only sets
DESTDIR but also passes plugindir path. This results in double
DESTDIR being in the plugin path, Drop one.

e20dd2a4fd build: fix distdir with wireshark disabled
Even though the Makefile has WITH_WIRESHARK guards, the _SOURCES
variables are still processed when adding bits to the dist archive.

plugin.c is a generated file that is only built when wireshark is
enabled and it shouldn't be distributed, so use 'nodist'
