Because it's a valid combination. p2p still uses a separate channel
for qemu migration, so there's value in letting the user specify a manual
migrate URI for overriding auto-port, or libvirt's FQDN lookup.
What _isn't_ allowed is --migrateuri and TUNNELLED, since there is
no separate migration channel. Disallow that instead

Introduced by commit 1daa4ba33a. vshCommandOptStringReq returns
0 on *success* or the option is not required && not present, both
are right result. Error out when returning 0 is not correct.

Automake already passes all CFLAGS to the linker too, so it
is not necessary to set WARN_LDFLAGS in addition to the

These all existed before virfile.c was created, and for some reason
weren't moved.
This is mostly straightfoward, although the syntax rule prohibiting
write() had to be changed to have an exception for virfile.c instead
of virutil.c.
This movement pointed out that there is a function called
virBuildPath(), and another almost identical function called
virFileBuildPath(). They really should be a single function, which
I'll take care of as soon as I figure out what the arglist should look
like.
Recent commit '53531e16' resulted in a new Coverity warning regarding
a missing break in the ':' options processing. Adjust the commit to
avoid the issue.
The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.
Mention file/volume contents instead of just 'file'/'volume'.
Also change Download->download in vol-download help,
to be consistent with other volume commands.

For long options, print:
* the option as specified by the user if it's unknown
* the canonical long option if its argument is not
a number (and should be)
And for missing arguments, print both the short and
the long option name.
(Doing only one of those would require either parsing
argv ourselves or let getopt print the errors, since
we can't tell long and short options apart by optopt
or longindex)

'virsh help | grep nodedev-det' shows only nodedev-detach, but
'virsh help nodedev | grep nodedev-det' also shows the old alias
nodedev-dettach that we intentionally hid in commit af3f9aab.

The virsh nodedev-detach command has a new --driver option. If it's
given virsh will attempt to use the new virNodeDeviceDetachFlags API
instead of virNodeDeviceDettach. Validation of the driver name string
is left to the hypervisor (qemu accepts "kvm" or "vfio". The only
other hypervisor that implements these functions is xen, and it only
accepts NULL).
This patch factors out the vCPU count retrieval including fallback means
into vshCPUCountCollect() and removes the duplicated code to retrieve
individual counts.
The --current flag (this flag is assumed by default) now works also with
--maximum or --active without the need to explicitly specify the state
of the domain that is requested.
This patch also fixes the output of "virsh vcpucount domain" on inactive
domains:
Before:
$ virsh vcpucount domain
maximum config 4
error: Requested operation is not valid: domain is not running
current config 4
error: Requested operation is not valid: domain is not running
After:
$virsh vcpucount domain
maximum config 4
current config 4
.. and for transient domains too:
Before:
$ virsh vcpucount transient-domain
error: Requested operation is not valid: cannot change persistent config of a transient domain
maximum live 3
error: Requested operation is not valid: cannot change persistent config of a transient domain
current live 1
After:
$ virsh vcpucount transient-domain
maximum live 3
current live 1
Using of a incorrect value for the --holdtime option was silently
ignored and 0 was used. In case a negative number was used, it
overflowed as the API expects a unsigned int.
Fix the data type and getter function type and report errors on
incorrect values.
With this patch, include public headers in "" form is only allowed
for "internal.h". And only the external tools (examples|tools|python
|include/libvirt) can include the public headers in <> form.
Explicitly state that using incomplete XML definition snippets for hot-management
commands may have unexpected results due to autogenerating values for some of
the fields if they aren't specified explicitly.
Newer pod (hello rawhide) complains if you attempt to mix bullets
and non-bullets in the same list:
virsh.pod around line 3177: Expected text after =item, not a bullet
As our intent was to nest an inner list, we make that explicit to
keep pod happy.
* tools/virsh.pod (ENVIRONMENT): Use correct pod syntax.
This patch improves the error message after disconnecting from the
hypervisor and adds the close callback operations required not to leak
the callback reference.
The function is used to establish connection so it should be in the main
virsh file. This movement also enables further improvements done in next
patches.
Note that the "connect" command has moved from the host section of virsh to the
main section. It is now listed by 'virsh help virsh' instead of 'virsh help
host'.
Before closing the connection we unregister the close callback
to prevent a reference leak.
Further, the messages on virConnectClose != 0 are a bit more specific
now.

By passing the flags -z relro -z now to the linker, we can force
it to resolve all library symbols at startup, instead of on-demand.
This allows it to then make the global offset table (GOT) read-only,
which makes some security attacks harder.

PIE (position independent executable) adds security to executables
by composing them entirely of position-independent code (PIC. The
.so libraries already build with -fPIC. This adds -fPIE which is
the equivalent to -fPIC, but for executables. This for allows Exec
Shield to use address space layout randomization to prevent attackers
from knowing where existing executable code is during a security
attack using exploits that rely on knowing the offset of the
executable code in the binary, such as return-to-libc attacks.

virsh schedinfo was able to set only one parameter at a time (not
counting the deprecated options), but it is useful to set more at
once, so this patch adds the possibility to do stuff like this:
virsh schedinfo <domain> cpu_shares=0 vcpu_period=0 vcpu_quota=0 \
emulator_period=0 emulator_quota=0
Invalid scheduler options are reported as well. These were previously
reported only if the command hadn't updated any values (when
cmdSchedInfoUpdate returned 0).

The virsh(1) man page wasn't saying anything about the 'migrateuri'
parameter other than it can be usually omitted. A patched version of
docs/migrate.html.in is taken in this patch to fix that up in the man
page.
