it was using atoi direct without checking leading to confusion
in case of flag error for example with -c
* tools/virsh.c: vshParseArgv() use virStrToLong_i and remove the
unchecked atoi used to parse teh parameter
After playing around with virsh setmaxmem for a bit,
I ran into some surprising behavior; if a hypervisor does
not support the virDomainSetMaxMemory() API, but the value
specified for setmaxmem is less than the current amount
of memory in the domain, the domain would be ballooned
down *before* an error was reported.
To make this more consistent, run virDomainSetMaxMemory()
before trying to shrink; that way, if an error is thrown,
no changes to the running domain are made.

The virsh command "setmem" takes as input a number that
should represent an unsigned long number of kilobytes. Fix
cmdSetmem to properly parse this as an unsigned long instead
of an int.

The virsh option error reporting was not being used
consistently; some commands would spit out errors on
missing required options while others would just silently fail.
However, vshCommandOptString knows which ones are required
and which ones aren't, so make it spit out an error where
appropriate. The rest of the patch is just cleaning up
the uses of vshCommandOptString to deal with the new error
reporting.

This patch removes the individual author names from the libvirtd and virsh
man pages, instead referring to the main AUTHORS file distributed with
libvirt. This approach is needed, as we can't guarantee unicode support
across all versions of pod2man used with libvirt.
Additionally, this patch includes the libvirtd man page in the spec file
used with "make rpm". Without this patch "make rpm" is broken.
When printing out size_t, we need to use %zu to make sure it
will continue to compile on both 32-bit and 64-bit platforms.

vshMalloc and friends always exit() on allocation failure,
so there is no reason to do checking for NULL in the code

This patch adds a new --details option to the virsh vol-list
command, making its output more useful when many luns are
present.
Addresses BZ # 605543
https://bugzilla.redhat.com/show_bug.cgi?id=605543
https://bugzilla.redhat.com/show_bug.cgi?id=609044 complained
that 'virsh help pool-create-as' didn't document the shortcut
that you can do 'virsh pool-create-as $name $type --target $target'
rather than having to supply the four optional source- arguments
in order to fill out the necessary positional arguments.
This one-liner changes the help output to hopefully make this more obvious:
NAME
pool-create-as - create a pool from a set of args
SYNOPSIS
pool-create-as <name> [--print-xml] <type> [<source-host>] [<source-path>] [<source-dev>] [<source-name>] [<target>] [--source-format <string>]
DESCRIPTION
Create a pool.
OPTIONS
[--name] <string> name of the pool
--print-xml print XML document, but don't define/create
[--type] <string> type of the pool
[--source-host] <string> source-host for underlying storage
[--source-path] <string> source path for underlying storage
[--source-dev] <string> source device for underlying storage
[--source-name] <string> source name for underlying storage
[--target] <string> target for underlying storage
--source-format <string> format for underlying storage
* tools/virsh.c (vshCmddefHelp): Make it more obvious that data
arguments may, but not must, be specified by option leaders.
This patch adds a new --details option to the virsh pool-list
command, making its output more useful to people who use virsh
for significant lengths of time.

http://bugzilla.redhat.com/601143, part 1 - document existing
behavior. Ever since Mar 2010 (commit ced154cb), the use of
'attach-disk' or 'attach-device' to change cdrom/floppy media has been
documented but deprecated, but the replacement to use 'update-device'
was not documented.
* tools/virsh.c (cmdAttachInterface, cmdAttachDisk): Fix bad error
message.
* tools/virsh.pod (attach-device, attach-disk): Refer to
update-device for cdrom and floppy behavior.
(update-device): Add documentation.
This patch adds the persistence status (yes/no) to the output of the virsh
dominfo and pool-info commands. This patch also adds the autostart status
to the output of the virsh pool-info command.
Red Hat BZ for this:
https://bugzilla.redhat.com/show_bug.cgi?id=603696
Presently the vol-key command only supports being provided with
a volume path.
This patch adds support for providing it with a pool and volume
identifier pair as well.
virsh # vol-key --pool <pool-name-or-uuid> <vol-name-or-path>
Make 'start --paused' mirror 'create --paused'.
* tools/virsh.c (cmdStart): Use new virDomainCreateWithFlags API
when needed.
* tools/virsh.pod (start): Document --paused.
This patch adds two new parameters to the vol-create-as command:
--backing-vol <volume-name-or-key-or-path>
--backing-vol-format <format-of-backing-vol>
virsh # vol-create-as guest_images_lvm snapvol1 5G --backing-vol \
rhel6vm1lun1
Vol snapvol1 created
virsh # vol-create-as image_dir qcow2snap2 5G --format qcow2 \
--backing-vol imagevol1.qcow2 \
--backing-vol-format qcow2
Vol qcow2snap2 created
Additionally, the virsh man page update fixes incorrect snapshot
parameters that were included in my prior bulk volume command patch.
This patch adds a new "vol-pool" command to virsh, to round out the
identifier conversion functions for volumes in virsh. Now it is
possible to work with volumes when starting from just a volume key
or volume path.
When creating pools from dedicated disks, the existing pool-define-as
and pool-create-as commands are a bit non-optimal.
Ideally, a person would be able to specify all of the required options
directly on the command line instead of having to edit the XML.
At the moment, there is no way to specify the format type (ie gpt) so it
gets included in the XML the pool is constructed with.
Please find attached a simple (tested) patch to add an optional
"--source-format 'type'" to virsh. This is patched against current git
master and will apply cleanly.
Also created a Red Hat BZ ticket for this (#597790) for tracking.
This is just a trivial patch to virsh.pod (from git master). It adds the
following pieces to the virsh man page:
+ Shows the --inactive and --all optional parameters for the list
command.
Closes Bugzilla #575512, reported by Renich Bon Ciric
https://bugzilla.redhat.com/show_bug.cgi?id=575512
+ Corrects the existing description of the list command, to now say
that only running domains are listed if no domains are specified.
The man page up until this point has said all domains are listed if
no domains are specified, which is incorrect.
+ Adds the "shut off" state to the list of states for the list
command.
+ Adds a missing =back around line 755, that pod2man was complaining
was missing.
Matthias noted that the line:
virt_aa_helper_LDFLAGS = $(WARN_CFLAGS)
looks inconsistent, so I did an audit.
Currently, the set of compiler warning flags passed to gcc as $CC are
equally permitted as the set of linker flags passed to gcc as $LD, so
there was no problem with that usage. But if we ever get in a
situation where $CC and $LD treat particular flags differently, using
the right variable form will make it easier.
In the process, I spotted a couple of typos that were omitting useful
flags, as well as specifying a -l under the wrong variable.
* acinclude.m4 (LIBVIRT_COMPILE_WARNINGS): Define WARN_LDFLAGS as
an alias for WARN_CFLAGS.
* tools/Makefile.am (virsh_LDFLAGS): Use more canonical spelling.
* proxy/Makefile.am (libvirt_proxy_LDFLAGS): Likewise. Move
library...
(libvirt_proxy_LDADD): ...here.
* src/Makefile.am (virt_aa_helper_LDFLAGS): Use more canonical
spelling of WARN_LDFLAGS.
(libvirt_parthelper_LDFLAGS, libvirt_lxc_LDFLAGS): Likewise. Use
correct spelling of COVERAGE_LDFLAGS.
Reported by Matthias Bolte.
For example, virsh -c test:///default schedinfo 1 --set P=k would
mistakenly exit successfully, giving no indication that it had failed
to set the scheduling parameter "P".
* tools/virsh.c (cmdSchedinfo): Diagnose an invalid --set j=k option,
rather than silently ignoring it.
* tests/virsh-schedinfo: New test for the above.
* tests/Makefile.am (test_scripts): Add it.

Support for live migration between hosts that do not share storage was
added to qemu-kvm release 0.12.1.
It supports two flags:
-b migration without shared storage with full disk copy
-i migration without shared storage with incremental copy (same base image
shared between source and destination).
I tested the live migration without shared storage (both flags) for native
and p2p with and without tunnelling. I also verified that the fix doesn't
affect normal migration with shared storage.
WIN32 is always defined when __MINGW32__ is defined, but the
converse is not true. WIN32 is more generic, if someone were
to ever attempt porting to a microsoft compiler. This does
not affect Cygwin, which intentionally does not define WIN32.
* src/qemu/qemu_driver.c (qemuDomainGetBlockInfo): Use more
generic flag macro.
* src/storage/storage_backend.c
(virStorageBackendUpdateVolTargetInfoFD)
(virStorageBackendRunProgRegex): Likewise.
* tools/console.h (vshRunConsole): Likewise.
This applies a fix to thos functions similar to that made to cmdEdit
in 270895063d, thus fnixing a memory
leak - if tmp is unlinked and NULLed early in the function, the memory
used by tmp is never freed. Since we will always unlink tmp prior to
freeing its memory at the end of the function, just remove the earlier
code and let cleanup: do the cleanup.
Ubuntu's gntls package generates an Issuer line that looks like this:
Issuer: C=US,ST=NY,L=Rochester,O=example.com,CN=example.com CA,EMAIL=hostmaster@example.com
While Red Hat's looks like this
Issuer: CN=Red Hat Emerging Technologies
Note the leading whitespace, and the additional fields in the former.
This patch updates the regular expression to:
* trim leading characters before "Issuer:"
* trim anything between Issuer: and CN=
* trim anything after the next ,
I've tested this against the certool output of both RH and Ubuntu
generated certs.
