* 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.
Add dump_image_format[] to qemu.conf and support compressed dump
at virsh dump. coredump compression is important for saving disk space
in an environment where multiple guests run.
In general, "disk space for dump" is specially allocated and will be
a dead space in the system. It's used only at emergency. So, it's better
to have both of save_image_format and dump_image_format. "save" is done
in scheduled manner with enough calculated disk space for it.
This code reuses some of save_image_format[] and supports the same format.
Changelog:
- modified libvirtd_qemu.aug
- modified test_libvirtd_qemu.aug
- fixed error handling of qemudSaveCompressionTypeFromString()
When we mount any cgroup without "-o devices", we will fail to start vms:
error: Failed to start domain vm1
error: Unable to deny all devices for vm1: No such file or directory
When we mount any cgroup without "-o cpu", we will fail to get schedinfo:
Scheduler : posix
error: unable to get cpu shares tunable: No such file or directory
We should only use the cgroup controllers which are mounted on host.
So I add virCgroupMounted() for qemuCgroupControllerActive()

Don't disable the VirtualBox driver when configure can't find
VBoxXPCOMC.so, rely on detection at runtime again instead.
Keep --with-vbox=/path/to/virtualbox intact, added to for:
https://bugzilla.redhat.com/show_bug.cgi?id=609185
Detection order for VBoxXPCOMC.so:
1. VBOX_APP_HOME environment variable
2. configure provided location
3. hardcoded list of known locations
4. dynamic linker search path
Also cleanup the glue code and improve error reporting.
fix warning
CC libvirt_util_la-virtaudit.lo
cc1: warnings being treated as errors
util/virtaudit.c: In function 'virAuditEncode':
util/virtaudit.c:146: error: implicit declaration of function 'virAsprintf' [-Wimplicit-function-declaration]
util/virtaudit.c:146: error: nested extern declaration of 'virAsprintf' [-Wnested-externs]
The 2nd and 3rd hunk show the only double-closed file descriptor code part that I found while trying to clean up close(). The first hunk seems a harmless cleanup in that same file.
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.
During virtual network startup, the iptables rule that allows tftp
traffic is only added if network->def->tftproot is non-empty, but when
the virtual network is destroyed, we had been unconditionally trying
to delete the rule. This was harmless, except that it created a bogus
error message.
This patch conditionalizes the delete command in the same manner that
the insert command is already conditionalized.
Reordered the bindings into alphabetical order, added a link to
the php-libvirt source on Github, plus gave the direct package
names needed for Python usage on RHEL/Fedora, and Ubuntu.
Commit 9bd3cce0d2 added virFork and
virDriverLoadModule to libvirt_private.syms, but virFork didn't have
a body on Win32 and virDriverLoadModule was already correctly
exported conditional via libvirt_driver_modules.syms.
Add auditing of all initial disk/net assignments to QEMU guests
at startup. Add auditing for all hotplug & unplug events and
disk media changes.
* src/qemu/qemu_driver.c: Add disk/net resource auditing
Add a helper API for ecscaping the value in audit log
messages
* src/util/virtaudit.h, src/util/virtaudit.c,
src/libvirt_private.syms: Add virAuditEncode
Revert most of commit a8b5f9bd27.
The audit hooks will be re-added directly in the QEMU driver code
in a future commit
* daemon/remote.c: Remove all audit logging hooks
* src/qemu/qemu_driver.c: Remove all audit logging hooks
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.
When using 0-prefixed numbers, QEmu will interpret them as octal numbers
(as C convention says); this means that if you attach a device that has
addr > 10 (decimal) you're going to attach a different device.
* 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.
The default location for the XML catalog file, /etc/xml/catalog,
used when validating the generated html docs, isn't correct for
MacOS X.
This commit adds an option to the configure script, allowing the
default to be overridden:
--with-xml-catalog-file=/path/to/xml/catalog/file
When failing to start a virtual network, we have to cleanup,
tearing down any iptables rules. If the iptables rules were
not present yet though, this raises an error, which squashes
the original error we were handling.
* src/network/bridge_driver.c: When failing to start a virtual
network, don't squash the original error in cleanup
Previously, only the API docs were installed, rather than the
complete documentation set. This commit ensures the complete
documentation set is installed.
With SystemTap 1.0 a part of the generated macros in probes.h
expands to:
volatile __typeof__(((name))) arg2 = (name);
GCC reports an 'invalid initialize' error when name has type
char[]. Therfore, add casts to char* to avoid this.
The network address was being set to 192.168.122.0 instead
of 192.168.122.0/24. Fix this by removing the unneccessary
'network' field from virNetworkDef and just pass the
network address and netmask into the iptables APIs directly.
* src/conf/network_conf.h, src/conf/network_conf.c: Remove
the 'network' field from virNEtworkDef.
* src/network/bridge_driver.c: Update for iptables API changes
* src/util/iptables.c, src/util/iptables.h: Require the
network address + netmask pair to be passed in
* tools/virsh.c: add missing option from the CLI to allows setting
up the NIC model type when attaching an interface
* tools/virsh.pod: extend documentation
* AUTHORS: add Osier Yang to the list
So far, readonly=on option is used when qemu supports -device. However,
there are qemu versions which support readonly option with -drive
although they don't have support for -device.
