The bandwidth units for blockpull and blockcopy are in Megabytes per
Second, not Megabits per Second.

This patch adds two macros: VIR_DOMAIN_SCHEDULER_EMULATOR_PERIOD,
VIR_DOMAIN_SCHEDULER_EMULATOR_QUOTA for controlling cpu bandwidth
for emulator activities not tied to vcpus
Since the move to systemd libvirt-guests doesn't output this progress
information anymore. This patch brings back this feature.
It is helpful to show the admin what the system is waiting for and what
is left of the timeout (e.g. for calibrating the shutdown timing of a ups).
Rewriting the current line with \r doesn't work anymore in the context
of systemd. So always write new lines, but move to 5 second intervals
to avoid flooding the console.
Last of the file splits.

* tools/Makefile.am (virsh_SOURCES): Build it.
* tools/virsh.c: Use new header.
* tools/virsh-nwfilter.c: Likewise.
Another worthwhile split, needed one more public function.
* tools/virsh-nodedev.h: New file.
* tools/Makefile.am (virsh_SOURCES): Build it.
* tools/virsh-nodedev.c: Use new header.
* tools/virsh.c: Likewise.
(vshTreePrint): Export.

* tools/Makefile.am (virsh_SOURCES): Build it.
* tools/virsh.c: Use new header.
* tools/virsh-network.c: Likewise.
(vshCommandOptNetworkBy): Update signature.
Another relatively easy split, since helper functions were fixed
in the previous patch.
* tools/virsh-interface.h: New file.
* tools/Makefile.am (virsh_SOURCES): Build it.
* tools/virsh.c: Use new header.
* tools/virsh-interface.c: Likewise.
(vshCommandOptInterfaceBy): Check flags.
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.
Another file worth compiling on its own instead of by .c inclusion.
* tools/virsh-domain-monitor.h: New file.
* tools/Makefile.am (virsh_SOURCES): Build it.
* tools/virsh.h (vshGetDomainDescription): Move to correct
header.
* tools/virsh-domain-monitor.c: Use new header.
* tools/virsh.c: Likewise.
* tools/virsh-domain.c: Likewise.
C99 says that __foo naming is reserved for the compiler. Besides,
we had several different styles in use; this consolidates things
to set up the typedefs up front then declare the types with
consistent naming.
* tools/virsh.h: Use consistent struct naming.
* tools/virsh.c (_vshCommandParser): Likewise.
The virsh-domain.c file was pretty self-contained; the only
entry point was the table of command definitions. The bulk
of this patch is making more functions in virsh.c reusable.
A later patch will clean up poor naming choices.
* tools/Makefile.am (virsh_SOURCES): Build virsh-domain.c.
* tools/virsh-domain.h: New file.
* tools/virsh.h (virshReportError, vshResetLibvirtError)
(vshAskReedit, vshStreamSink): Declare.
* tools/virsh.c: Switch from using .c to .h.
(virshReportError, vshResetLibvirtError, vshAskReedit)
(vshStreamSink, prettyCapacity): Export.
(vshCatchInt): Move...
* tools/virsh-domain.c: ...into sole user. Use header.
Having one .c file include another does not give any compilation
benefits; move towards modular .o files by first splitting out
reused declarations into a new virsh.h. This patch doesn't try
very hard to see which functions are used or not, to make it
easier to review the file split. Future patches can further trim
the header to be smaller.
* tools/Makefile.am (virsh_SOURCES): List new file, and prepare
for others.
* tools/virsh.c: Split declarations...
* tools/virsh.h: ...into new file, and make several functions
non-static.
* tools/virsh-domain-monitor.c (vshGetDomainDescription): Make
non-static.
It's easier to order things in topological order than it is to
forward declare in one file for use only by one other file.
* tools/virsh.c (vshWatchJob, parseRateStr)
(vshDomainStateToString, vshDomainStateReasonToString)
(vshDomainControlStateToString, vshDomainVcpuStateToString): Drop
useless prototypes.
* tools/virsh-domain.c (vshWatchJob): Move earlier.
The '#endif' for a WIN32 conditional was placed one function
too high, leaving the impl of the console command enabled
and referencing functions that were disabled
* tools/virsh.c: New macro vshStrcasecmp
* tools/virsh-domain-monitor.c: Use vshStrcasecmp instead of
strcasecmp
* tools/virsh-snapshot.c: Likewise
* cfg.mk: Only avoid doing strcase checking for virsh.c
As the consensus in:
https://www.redhat.com/archives/libvir-list/2012-July/msg01692.html,
this patch is to destroy conf/virdomainlist.[ch], folding the
helpers into conf/domain_conf.[ch].
* src/Makefile.am:
- Various indention fixes incidentally
- Add macro DATATYPES_SOURCES (datatypes.[ch])
- Link datatypes.[ch] for libvirt_lxc
* src/conf/domain_conf.c:
- Move all the stuffs from virdomainlist.c into it
- Use virUnrefDomain and virUnrefDomainSnapshot instead of
virDomainFree and virDomainSnapshotFree, which are defined
in libvirt.c, and we don't want to link to it.
- Remove "if" before "free" the object, as virObjectUnref
is in the list "useless_free_options".
* src/conf/domain_conf.h:
- Move all the stuffs from virdomainlist.h into it
- s/LIST_FILTER/LIST_DOMAINS_FILTER/
* src/libxl/libxl_driver.c:
- s/LIST_FILTER/LIST_DOMAINS_FILTER/
- no (include "virdomainlist.h")
* src/libxl/libxl_driver.c: Likewise
* src/lxc/lxc_driver.c: Likewise

Similar to the previous patch, prepending 'help' to a partial
command string doesn't cut us any slack.
$ virsh help pool-define-as --name foo --type dir
error: command 'help' doesn't support option --name
This patch adds a few hacks to make 'help' ignore everything after the
first data bit, so the above command shows help output for pool-define-as.
Often times I find myself halfway through typing a long command when
I want to see 'help' output. I instinctively append '--help' to the
command I'm typing, only to get an error:
$ virsh vol-create-as foo --help
error: command 'vol-create-as' doesn't support option --help
This patch makes --help work in a pretty hacky way. One missing piece
here is that --help isn't listed as an option in the actual 'help <cmd>'
output, but maybe this can be a starting point for someone.
For some reason I only get this after applying subsequent upcoming
patches that touch virsh, but don't seem to actually cause the warning.
virsh.c: In function ‘vshCommandParse’:
virsh.c:2014:46: error: ‘opt_index’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
cc1: all warnings being treated as errors
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
I originally postet this into the Fedora bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=843836
Currently gracefully shutting down guest vms on host shutdown does not work on
Fedora 17, the guests are killed hard on system shutdown.
The reason is systemd considers libvirt-guests.service to be stopped when the
system is running:
$ systemctl status libvirt-guests.service
libvirt-guests.service - Suspend Active Libvirt Guests
Loaded: loaded (/usr/lib/systemd/system/libvirt-guests.service;
enabled)
Active: deactivating (stop) since Fri, 27 Jul 2012 15:47:31 +0200;
2min 48s ago
Process: 1085 ExecStart=/etc/init.d/libvirt-guests start
(code=exited, status=0/SUCCESS)
Control: 1150 (libvirt-guests)
CGroup: name=systemd:/system/libvirt-guests.service
└ control
├ 1150 /bin/sh /etc/init.d/libvirt-guests stop
└ 2257 sleep 1
libvirt-guests.service is defined as type "simple" in systemd (the default).
That means systemd will shut down the service when the start executable is
terminated after starting is done. Systemd will not call stop again on system
shutdown because it thinks it is already stopped.
The solution is to define it as type "oneshot" and set the flag
"RemainAfterExit". Then systemd will consider the service as active after
startup and will call the stop function on host shutdown.
This is a follow up patch of commit f9ce7dad6, it modifies all
the files which declare the copyright like "See COPYING.LIB for
the License of this software" to use the detailed/consistent one.
And deserts the outdated comments like:
* libvirt-qemu.h:
* Summary: qemu specific interfaces
* Description: Provides the interfaces of the libvirt library to handle
* qemu specific methods
*
* Copy: Copyright (C) 2010, 2012 Red Hat, Inc.
Uses the more compact style like:
* libvirt-qemu.h: Interfaces specific for QEMU/KVM driver
*
* Copyright (C) 2010, 2012 Red Hat, Inc.
On some fallback paths in virsh, error reported by the previously failed
API is cleared by virResetLastError() that doesn't free error stored by
virsh. This patch changes this to clear it using vshResetLibvirtError().
Virsh uses an error handler to save errors from libvirt. On some code
paths it's needed to clear libvirt errors and continue on fallback code
paths without reporting failure.
This patch adds function vshResetLibvirtError() that clears error
returned by libvirt and updates all places where the old two-line method
was used.
When undefining a domain and removing associated storage using "virsh
undefine --storage" the domain was at first undefined and after that the
storage removal proces was started. If the user specified an invalid
disk to remove, the error could not be corrected.
This patch moves enumeration and filtering of volumes that should be
removed before the domain is undefined, but the removal process is still
kept after the domain has been undefined.
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.
