* src/xen/xend_internal.c (xenDaemonFormatSxpr): Hoist verify
outside of function to avoid a -Wnested-externs warning.
* src/xen/xm_internal.c (xenXMDomainConfigFormat): Likewise.
Reported by Daniel P. Berrange.
* src/xen/xen_hypervisor.c (MAX_VIRT_CPUS): Move...
* src/xen/xen_driver.h (MAX_VIRT_CPUS): ...so all xen code can see
same value.
* src/xen/xend_internal.c (sexpr_to_xend_domain_info)
(xenDaemonDomainGetVcpusFlags, xenDaemonParseSxpr)
(xenDaemonFormatSxpr): Work if MAX_VIRT_CPUS is 64 on a platform
where long is 64-bits.
* src/xen/xm_internal.c (xenXMDomainConfigParse)
(xenXMDomainConfigFormat): Likewise.
https://bugzilla.redhat.com/show_bug.cgi?id=638285 - when migrating
a guest, it was very easy to provoke a race where an application
could query block information on a VM that had just been migrated
away. Any time qemu code obtains a job lock, it must also check
that the VM was not taken down in the time where it was waiting
for the lock.
* src/qemu/qemu_driver.c (qemudDomainSetMemory)
(qemudDomainGetInfo, qemuDomainGetBlockInfo): Check that vm still
exists after obtaining job lock, before starting monitor action.
A missing shell was noisy, and the use of command to decipher a
shell's absolute path requires "" rather than ''.
* configure.ac (lv_cv_wrapper_shell): Fix logic errors if candidate
shell is not available.
* .gitignore: Ignore file created when /bin/sh is old dash.
Reported by Matthias Bolte.
* cfg.mk (sc_prohibit_trailing_blank_lines): Delete; this is
adequately covered by maint.mk's sc_prohibit_empty_lines_at_EOF.
* .x-sc_prohibit_empty_lines_at_EOF: New file, to exempt raw
patches.
* Makefile.am (EXTRA_DIST): Include new exemption.
* tools/virsh.c (opts_freecell, opts_memtune, opts_vcpupin)
(opts_setvcpus, opts_setmaxmem, opts_setmem)
(opts_migrate_setmaxdowntime): Use VSH_OT_INT when only an integer
is expected.
(vshCmddefHelp, vshCmddefGetData): Allow mandatory VSH_OT_INT
arguments.
Older dash mistakenly truncates regular files when using <> redirection;
this kills our use of double dd to reduce storage overhead when
saving qemu images. But qemu insists on running a command through
/bin/sh, so we work around it by having qemu run $sh -c 'real command'
when we have a replacement $sh in mind.
* configure.ac (VIR_WRAPPER_SHELL): Define to a replacement shell,
if /bin/sh is broken on <> redirection.
* src/qemu/qemu_monitor.h (VIR_WRAPPER_SHELL_PREFIX)
(VIR_WRAPPER_SHELL_SUFFIX): New macros.
* src/qemu/qemu_monitor_text.c (qemuMonitorTextMigrateToFile): Use
them.
* src/qemu/qemu_monitor_json.c (qemuMonitorJSONMigrateToFile):
Likewise.
* src/libvirt_private.syms: Sort by header name, then within
header, and drop duplicate virNetworkDefParseNode,
virFileLinkPointsTo and virXPathBoolean.
This patch series focuses on xendConfigVersion 2 (xm_internal) and 3
(xend_internal), but leaves out changes for xenapi drivers.
See this link for more details about vcpu_avail for xm usage.
http://lists.xensource.com/archives/html/xen-devel/2009-11/msg01061.html
This relies on the fact that def->maxvcpus can be at most 32 with xen.
* src/xen/xend_internal.c (xenDaemonParseSxpr)
(sexpr_to_xend_domain_info, xenDaemonFormatSxpr): Use vcpu_avail
when current vcpus is less than maximum.
* src/xen/xm_internal.c (xenXMDomainConfigParse)
(xenXMDomainConfigFormat): Likewise.
* tests/xml2sexprdata/xml2sexpr-pv-vcpus.sexpr: New file.

* tests/qemuxml2xmltest.c (mymain): Likewise.
* tests/qemuxml2argvdata/qemuxml2argv-smp.args: New file.
* tools/virsh.c (cmdSetvcpus): Add new flags. Let invalid
commands through to driver, to ease testing of hypervisor argument
validation.
(cmdMaxvcpus, cmdVcpucount): New commands.
(commands): Add new commands.
* tools/virsh.pod (setvcpus, vcpucount, maxvcpus): Document new
behavior.
Although this patch adds a distinction between maximum vcpus and
current vcpus in the XML, the values should be identical for all
drivers at this point. Only in subsequent per-driver patches will
a distinction be made.
In general, virDomainGetInfo should prefer the current vcpus.
* src/conf/domain_conf.h (_virDomainDef): Adjust vcpus to unsigned
short, to match virDomainGetInfo limit. Add maxvcpus member.
* src/conf/domain_conf.c (virDomainDefParseXML)
(virDomainDefFormat): parse and print out vcpu details.
* src/xen/xend_internal.c (xenDaemonParseSxpr)
(xenDaemonFormatSxpr): Manage both vcpu numbers, and require them
to be equal for now.
* src/xen/xm_internal.c (xenXMDomainConfigParse)

* src/qemu/qemu_driver.c (qemudDomainHotplugVcpus): Likewise.
* src/opennebula/one_conf.c (xmlOneTemplate): Likewise.
Note - this wrapping is completely mechanical; the old API will
function identically, since the new API validates that the exact
same flags are provided by the old API. On a per-driver basis,
it may make sense to have the old API pass a different set of flags,
but that should be done in the per-driver patch that implements
the full range of flag support in the new API.
* src/esx/esx_driver.c (esxDomainSetVcpus, escDomainGetMaxVpcus):
Move guts...
(esxDomainSetVcpusFlags, esxDomainGetVcpusFlags): ...to new
functions.
(esxDriver): Trivially support the new API.
* src/openvz/openvz_driver.c (openvzDomainSetVcpus)

* src/xenapi/xenapi_driver.c (xenapiDomainSetVcpus)
(xenapiDomainSetVcpusFlags, xenapiDomainGetMaxVcpus)
(xenapiDomainGetVcpusFlags, xenapiDriver): Likewise.
(xenapiError): New helper macro.
Factors common checks (such as nonzero vcpu count) up front, but
drivers will still need to do additional flag checks.
* src/libvirt.c (virDomainSetVcpusFlags, virDomainGetVcpusFlags):
New functions.
(virDomainSetVcpus, virDomainGetMaxVcpus): Refer to new API.
API agreed on in
https://www.redhat.com/archives/libvir-list/2010-September/msg00456.html,
but modified for enum names to be consistent with virDomainDeviceModifyFlags.
* include/libvirt/libvirt.h.in (virDomainVcpuFlags)
(virDomainSetVcpusFlags, virDomainGetVcpusFlags): New
declarations.
* src/libvirt_public.syms: Export new symbols.
Syntax agreed on in
https://www.redhat.com/archives/libvir-list/2010-September/msg00476.html
<domain ...>
<vcpu current='x'>y</vcpu>
...
can now be used to specify 1 <= x <= y current vcpus, in relation
to the boot-time max of y vcpus. If current is omitted, then
current and max are assumed to be the same value.
* docs/schemas/domain.rng: Add new attribute.
* docs/formatdomain.html.in: Document it.
* tests/qemuxml2argvdata/qemuxml2argv-smp.xml: Add to
domainschematest.
* tests/xml2sexprdata/xml2sexpr-pv-vcpus.xml: Likewise.
* tools/virsh.c (vshCmdOptType): Add VSH_OT_ARGV. Delete
unused VSH_OT_NONE.
(vshCmddefGetData): Special case new opt flag.
(vshCmddefHelp): Display help for argv.
(vshCommandOptArgv): New function.
https://bugzilla.redhat.com/show_bug.cgi?id=623903 documents a qemu
bug that causes libvirt to hang if virt-manager happens to be
querying balloon info when a guest is paused. Until the qemu bug
is fixed, people need to know how to avoid the issue.
* docs/formatdomain.html.in (Memory balloon device): Mention
model='none'.
* .gnulib: Update to latest, for termios fix.
* configure.ac (AC_CHECK_HEADERS): Drop redundent check.
* bootstrap: Synchronize from upstream.
Reported by Daniel P. Berrange.
'make -C src rpcgen' is supposed to be idempotent. But commit
f928f43b7b mistakently manually edited a generated file rather
than fixing the upstream file.
* src/remote/remote_protocol.x (remote_memory_param_value): Use
correct spelling of enum values.
* src/remote/remote_protocol.c: Regenerate.
This makes 'virsh --conn test:///default help help' work right;
previously, the abbreviation confused our hand-rolled option parsing.
* tools/virsh.c (vshParseArgv): Use getopt_long feature, rather
than (incorrectly) reparsing options ourselves.
* tools/virsh.c (malloc, calloc, realloc, strdup): Enforce that
within this file, we use the safe vsh wrappers instead.
(cmdNodeListDevices, cmdSnapshotCreate, main): Fix violations of
this policy.
* .gnulib: Update to latest, for bootstrap fixes.
* bootstrap: Synchronize with upstream.
* bootstrap.conf: Add pkg-config pre-requisite.
* autogen.sh: Tweak wording message.
Reported by Justin Clift, and with feedback from Bruno Haible.
The <vcpu cpuset=...> attribute has been available since commit
e193b5dd, but without documentation or RNG validation.
* docs/schemas/domain.rng (vcpu): Further validate cpuset.
* docs/formatdomain.html.in: Document it.
* src/conf/domain_conf.c: Fix typos.
Partial reversion of commit 76d87a59, now that bootstrap is smarter.
* .gnulib: Update to latest, for poll and bootstrap fixes.
* bootstrap: Resync from gnulib.
* autogen.sh: Drop redundant tool checks; bootstrap does them
better, by honoring environment variables.
* examples/domain-events/events-c/Makefile.am (INCLUDES)
(event_test_LDADD): Use gnulib library during build.
* bootstrap.conf (gnulib_tool_option_extras): Revert --libtool
addition, now that updated bootstrap does it for us.

Before this patch, the testsuite was noisy:
TEST: qemuargv2xmltest
........................................ 40
................20:41:28.046: warning : qemuParseCommandLine:6565 : unknown QEMU argument '-unknown', adding to the qemu namespace
20:41:28.046: warning : qemuParseCommandLine:6565 : unknown QEMU argument 'parameter', adding to the qemu namespace
. 57 OK
PASS: qemuargv2xmltest
It's not a real failure (which is why the test was completing
successfully), so much as an intentional warning to the user that use
of the qemu namespace has the potential for undefined effects that
leaked through the default logging behavior. After this patch series,
all tests can access any logged data, and this particular test can
explicitly check for the presence or absence of the warning, such that
the test output becomes:
TEST: qemuargv2xmltest
........................................ 40
................. 57 OK
PASS: qemuargv2xmltest
* tests/testutils.h (virtTestLogContentAndReset): New prototype.
* tests/testutils.c (struct virtTestLogData): New struct.
(virtTestLogOutput, virtTestLogClose, virtTestLogContentAndReset):
New functions.
(virtTestMain): Always capture log data emitted during tests.
* tests/qemuargv2xmltest.c (testCompareXMLToArgvHelper, mymain):
Use flag to mark which tests expect noisy stderr.
(testCompareXMLToArgvFiles): Add parameter to test whether stderr
was appropriately silent.
I got tired of seeing this.
config.status: executing libtool commands
/bin/rm: cannot remove `libtoolT': No such file or directory
config.status: executing po-directories commands
While I was at it, there were a couple other unused variables.
* configure.ac (RM, MV, TAR): Drop; nothing in libvirt directly uses
this, and assigning RM interferes with libtool.
* src/Makefile.am (libvirt.def, libvirt_qemu.def): '\}' and '\t'
are not required by POSIX. Use '}' and literal tab instead.
(install-data-local): Avoid sed -i.
* tests/read-bufsiz: Likewise.
Reported by Mitchell Hashimoto.
snprintf is currently implicitly picked up by getaddrinfo, but we
might as well make it explicit so that mingw doesn't break if
getaddrinfo changes to drop the dependency.
func doesn't matter for gcc compilation, but may help other compilers
cope with our use of __func__.
* bootstrap.conf (gnulib_modules): Add snprintf and func.
* src/xenapi/xenapi_driver.c (xenapiDomainGetInfo): Avoid using
XEN_VM_POWER_STATE_UNKNOWN, which disappeared in newer xenapi.
* src/xenapi/xenapi_utils.c (mapPowerState): Likewise.
* src/uml/uml_driver.c (umlMonitorCommand): Validate that enough
bytes were read to dereference both res.length, and that many
bytes from res.data.
Reported by Soren Hansen.
node_device/node_device_driver.c: In function 'nodeDeviceVportCreateDelete':
node_device/node_device_driver.c:423: error: implicit declaration of function 'stat' [-Wimplicit-function-declaration]
* src/node_device/node_device_driver.c (includes): Add <sys/stat.h>.
Add documentation for features added a while ago.
* docs/formatdomain.html.in (Time keeping): Update documentation
of <clock> element to match 0.8.0 addition.
https://bugzilla.redhat.com/622515 - When hot-unplugging CPUs,
libvirt failed to start a guest that had been pinned to CPUs that
were still online.
Tested on a dual-core laptop, where I also discovered that, per
http://www.cyberciti.biz/files/linux-kernel/Documentation/cpu-hotplug.txt,
/sys/devices/system/cpu/cpu0/online does not exist on systems where it
cannot be hot-unplugged.
* src/nodeinfo.c (linuxNodeInfoCPUPopulate): Ignore CPUs that are
currently offline. Detect readdir failure.
(parse_socket): Move guts...
(get_cpu_value): ...to new function, shared with...
(cpu_online): New function.
There has been a frequent complaint of:
make[2]: Entering directory `/home/remote/eblake/libvirt/po'
make[2]: *** No rule to make target `/config.status', needed by `Makefile'. Stop.
It happens after nuking and regenerating the po directory,
which is a common action after running anything like
'make dist' or 'make rpm' that dirties all the .po files.
Teach autogen.sh that it must regenerate po/Makevars to avoid
the missing variable declaration, and teach cfg.mk to recognize
that a nuked po directory is cause to rerun autogen.sh.
* cfg.mk (_update_required): Check for po/Makevars.
* autogen.sh (bootstrap): Run bootstrap if it got lost.
Diagnosed by Justin Clift.
Found by clang. Clang complained that virStorageBackendProbeTarget
could dereference NULL if backingStoreFormat was NULL, but since all
callers passed a valid pointer, I added attributes instead of null
checks.
* src/storage/storage_backend.c
(virStorageBackendQEMUImgBackingFormat): Kill dead store.
* src/storage/storage_backend_fs.c (virStorageBackendProbeTarget):
Likewise. Skip null checks, by adding attributes.
'./autobuild.sh' with lcov installed discovered that our
coverage support has been bit-rotting for a while. This
restores it back to a successful state, although I have
not yet spent any time looking through the resulting files to
look for low-hanging fruit in the unit test coverage front.
* configure.ac: Clear COMPILER_FLAGS at right place.
* Makefile.am (cov): Newer genhtml no longer likes plain -s.
* m4/compiler-flags.m4 (gl_COMPILER_FLAGS): Don't AC_SUBST
COMPILER_FLAGS; it is a shell variable for use in configure only.
* src/Makefile.am (AM_CFLAGS, AM_LDFLAGS): New variables, to make
it easier to provide global flag additions. Use throughout, to
uniformly apply coverage flags.
* .gitignore: Globally ignore gcov output.
* daemon/.gitignore: Simplify.
* src/.gitignore: Likewise.
* tests/.gitignore: Likewise.
The recent switch to enable -Wlogical-op paid off again.
gcc 4.5.0 (rawhide) is smarter than 4.4.4 (Fedora 13).
* src/xen/xend_internal.c (xenDaemonAttachDeviceFlags)
(xenDaemonUpdateDeviceFlags, xenDaemonDetachDeviceFlags): Use
correct operator.
