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.

When running virsh edit, we are unlinking and setting
the tmp variable to NULL before going to the end of the
function, meaning that we never free tmp. Since the
exit to the function will always unlink and free tmp,
just remove this bit of code and let it get done at the
end.

A few fixes will help make tools/virt-pki-validate.in useful on Debian
and Ubuntu. And one fix should be useful to everyone (see #3).
1) note our gnutls-bin package (in addition to your gnutls-utils
package) in the no-certtool error text
2) fix a bashism, == should be = in the case where /bin/sh is a symlink
to dash
3) $(SYSCONFDIR) cannot evaluate; set a single shell SYSCONFDIR
variable to the autoconf @SYSCONFDIR@ value, and use $SYSCONFDIR
everywhere

Noticed because virt-pki-validate was very inconsistent on
using tabs vs. 8 spaces, sometimes mixing both paradigms on
a single line.
'git diff -b' shows significant changes only in cfg.mk.
* cfg.mk (sc_TAB_in_indentation): Add a few files.
* daemon/libvirtd.init.in: Avoid tabs.
* tools/virt-pki-validate.in: Likewise.
* tools/virsh.c (vshCommandRun): Test only the initial value of
ctl->timing, so that static analyzers don't have to consider that
it might be changed by cmd->def->handler.
With Eric Blake's spelling corrections applied.
Unfortunately after the 0.8.0 release, but here's a beginning of the
documentation of the nwfilter functionality.
The network filter / snapshot / hooks code introduced some
non-portable pices that broke the win32 build
* configure.ac: Check for net/ethernet.h required by nwfile config
parsing code
* src/conf/nwfilter_conf.c: Define ethernet protocol constants
if net/ethernet.h is missing
* src/util/hooks.c: Disable hooks build on Win32 since it lacks
fork/exec/pipe
* src/util/threads-win32.c: Fix unchecked return value
* tools/virsh.c: Disable SIGPIPE on Win32 since it doesn't exist.
Fix non-portable strftime() formats
Document several missing commands. There's more work that could be
done, but incremental improvements is better than no patch at all.
* tools/virsh.pod (autostart, connect): Improve grammar.
(create): Improve example.
(domjobabort, domjobinfo, domxml-from-native, domxml-to-native):
Document.
(storage pool commands): New section.
When hitting failures in virsh, a common idiom is
to jump to a cleanup label, free some resources, and
then return a FALSE error code to vshCommandRun.
In theory, vshCommandRun is then supposed to print
out the last error. The problem is that many of
the cleanup paths have library calls to free resources,
and all of those library calls clear out the last error.
This is leading to situations where no error is being
reported at all.
This patch remedies the situation somewhat by
printing out the errors inside the command methods
themselves when we know it will go through a cleanup
path that will lose the error.

A lot of syntax check rules have to be rewritten, but the
result is easier to maintain. I tested each syntax rule
by intentionally introducing a temporary violation of the rule.
Additionally, some false positives for unmarked_diagnostics
crept in, and an improved copyright_format test caught some bugs.
* .gnulib: Update to latest.
* cfg.mk (sc_prohibit_test_minus_ao): Delete, it was moved into
gnulib's maint.mk.

Call me lazy: some shells use exit (e.g. sh), others use quit (e.g. ftp),
but I never remember which. So it's faster to write a patch to make
virsh take both than it is to take a 50-50 guess, and get it wrong
in half of my attempts.
* tools/virsh.c (commands): Add 'exit'.
* tools/virsh.pod: Document it.
Common Unix practice is to prefer VISUAL over EDITOR, particularly if
the editor of choice spawns a new window. Thus, it is also common to
see settings like EDITOR='emacs -nw', with the expectation that the
shell will parse this as an argument to 'emacs' and not try to invoke
a file containing a space.
If a user puts junk in EDITOR, they deserve what they get (much more
than virsh will misbehave); furthermore, sudo scrubs EDITOR by
default. So the blind use of metacharacters in EDITOR should not be
considered too much of a security issue.
* tools/virsh.c (editFile): Prefer VISUAL over EDITOR. Don't
reject shell metacharacters in EDITOR.
* tools/virsh.pod (edit, net-edit, ENVIRONMENT): Document VISUAL.
