Linefeed is missed in the help of node-memory-tune.
This patch just adds '\n' to get a correct help message.

The QEMU specific APIs all operate on domains, not the host,
so should be in the virsh-domain.c file / group

The virNodeSuspend API allows for a duration of 0, to mean no
timed wakup. virsh needlessly forbids this though

The libvirt coding standard is to use 'function(...args...)'
instead of 'function (...args...)'. A non-trivial number of
places did not follow this rule and are fixed in this patch.

We always expose individual bits from flags as separate options rather
than exposing a raw flags options. Since virNodeSuspendForDuration does
not currently support any flags, the only way of using this --flags
options that would not fail is "--flags 0", which is equivalent to
omitting the option. Thus it is highly unlikely anyone would actually be
using it and removing it should be safe.
Upstream kernel introduced new sysfs knob "merge_across_nodes" to
specify if pages from different numa nodes can be merged. When set
to 0, only pages which physically reside in the memory area of
same NUMA node can be merged. When set to 1, pages from all nodes
can be merged.
This patch supports the tuning by adding new param field
"shm_merge_across_nodes".
I was using qemu-monitor-command during development, and found it quite
hard to use. Compare the results of this patch on ease of reading:
$ virsh qemu-monitor-command dom '{"execute":"query-version"}'
{"return":{"qemu":{"micro":1,"minor":12,"major":0},"package":"(qemu-kvm-0.12.1.2)"},"id":"libvirt-7683"}
$ virsh qemu-monitor-command --pretty dom '{"execute":"query-version"}'
{
"return": {
"qemu": {
"micro": 1,
"minor": 12,
"major": 0
},
"package": "(qemu-kvm-0.12.1.2)"
},
"id": "libvirt-7674"
}
* tools/virsh-host.c (cmdQemuMonitorCommand): New option.
* tools/virsh.pod (qemu-monitor-command): Document it.
https://www.gnu.org/licenses/gpl-howto.html recommends that
the 'If not, see <url>.' phrase be a separate sentence.
* tests/securityselinuxhelper.c: Remove doubled line.
* tests/securityselinuxtest.c: Likewise.
* globally: s/; If/. If/
New command node-memory-tune to get/set the node memory parameters,
only two parameters are allowed to set (pages_to_scan, and sleep_millisecs,
see documents in this patch for more details).
Example of node-memory-tune's output:
Shared memory:
pages_to_scan 100
sleep_millisecs 20
pages_shared 0
pages_sharing 0
pages_unshared 0
pages_volatile 0
full_scans 0
Now that vshCommandRun() checks for the connection automaticaly, remove
all of the redundant checks in the code.
vshConnectionUsability() no longer needs to be exported and this patch
marks it static.
Although virsh command raises a correct error information, the command status
returns 0(true), this patch is used for fixing this issue.

In preparation for splitting virsh-interface.c, I found these
functions need to be declared in virsh.h, as well as one that
belongs more properly in virsh-domain.h. Also, since we
use the VSH_BY* flags in more than one function, I improved
how they are used.
* tools/virsh.h (vshNameSorter, vshCmdHasOption): Declare.
(VSH_BYID): Turn into enum.
(vshCommandOptDomainBy): Move...
* tools/virsh-domain.h): ...here.
* tools/virsh.c: (vshNameSorter): Export.
(cmd_has_option): Rename...
(vshCmdHasOption): ...and export.
(vshCommandOptDomainBy): Move...
* tools/virsh-domain.c (vshCommandOptDomainBy): ...here, adjust
signature, and check flags.
* tools/virsh-network.c (vshCommandOptNetworkBy): Update callers.
* tools/virsh-nwfilter.c (vshCommandOptNWFilterBy): Likewise.
* tools/virsh-secret.c (vshCommandOptSecret): Likewise.
* tools/virsh-domain-monitor.c (includes): Likewise.
* tools/virsh-host.c (includes): Likewise.
The splits are getting easier, with fewer cleanups needed in virsh.h.
* tools/virsh-host.h: New file.
* tools/Makefile.am (virsh_SOURCES): Build it.
* tools/virsh-host.c: Use new header.
* tools/virsh.c: Likewise.
List:
- some old libvir/libvirt rename leftovers (the only problem can be
if somebody parses 'virsh version' output really badly)
- remove pointless tags specified in some pages that are not used
Change the permissible minimum value of nodesuspend duration time
to 60 seconds. If option is less than the value, reports error.
Update virsh help and manpage the infomation.
Commands in host group moved from virsh.c to virsh-host.c,
* virsh.c: Remove commands in host group.
* virsh-host.c: New file, filled with commands in host group
* po/POTFILES.in: Add virsh-host.c
* cfg.mk: Skip to check config.h including for virsh-host.c
