dump-guest-memory is a new dump mechanism, and it can work when the
guest uses host devices. This patch adds a API to use this new
monitor command.
We will always use json mode if qemu's version is >= 0.15, so I
don't implement the API for text mode.
If we migrate to fd, spec->fwdType is not MIGRATION_FWD_DIRECT,
we will close spec->dest.fd.local in qemuMigrationRun(). So we
should set spec->dest.fd.local to -1 in qemuMigrationRun().
Bug present since 0.9.5 (commit 326176179).
When qemu cannot start, we may call qemuProcessStop() twice.
We have check whether the vm is running at the beginning of
qemuProcessStop() to avoid libvirt deadlock. We call
qemuProcessStop() with driver and vm locked. It seems that
we can avoid libvirt deadlock. But unfortunately we may
unlock driver and vm in the function qemuProcessKill() while
vm->def->id is not -1. So qemuProcessStop() will be run twice,
and monitor will be freed unexpectedly. So we should set
vm->def->id to -1 at the beginning of qemuProcessStop().
Commit d336dbdb tried to refactor sanlock to avoid building it
on RHEL for architectures where it is not available, but used
the wrong conditional.
* libvirt.spec.in (with_sanlock): Use %ifarch, not %ifnarch.
commit 27908453 introduces a regression, and it will
cause libvirt crashed when starting network.
The reason is that tapfd may be NULL, but we dereference
it without checking whether it is NULL.
When I run 'make dist', I receive the following error messages:

The reason is that we use probes.h before generating it.
After supporting multi function pci device, we only reserve function 1 on slot 1.
The user can use the other function on slot 1 in the xml config file. We should
detect this wrong usage.
The cpu bandwidth is applied at the vcpu group level. We should apply it
at the vm group level too, because the vm may do heavy I/O, and it will affect
the other vm.
We apply cpu bandwidth at the vcpu and the vm group level, so we must ensure
that max(child_quota) <= parent_quota when we modify cpu bandwidth.
In the XML file we now have
<cputune>
<shares>1024</shares>
<period>90000</period>
<quota>0</quota>
</cputune>
But the schedinfo parameter are being named
cpu_shares: 1024
cfs_period: 90000
cfs_quota: 0
The period/quota is per-vcpu value, so these new tunables should be named
'vcpu_period' and 'vcpu_quota'.
This patch implements cfs_period and cfs_quota's modification.
We can use the command 'virsh schedinfo' to query or modify cfs_period and
cfs_quota.
If you query period or quota from config file, the value 0 means it does not set
in the config file.
If you set period or quota to config file, the value 0 means that delete current
setting from config file.
If you modify period or quota while vm is running, the value 0 means that use
current value.
We disable some drivers when building without libvirtd in configure,
but we do not do the same thing in libvirt.spec. It may break rpm
building without libvirtd.
If virDomainSaveConfig() failed, we will return NULL to source,
and the vm is still available to restart during confirm() step in
v3 protocol. So we should kill it off in qemuMigrationFinish().
In v2 protocol, we should not set vm to NULL, because we hold
a reference of vm and should unrefernce it.
If we pass VIR_DOMAIN_AFFECT_LIVE | VIR_DOMAIN_AFFECT_CONFIG to
qemuGetSchedulerParametersFlags() or *nparams is less than 1,
we will unlock qemu_driver without locking it. It's very dangerous.
We should lock qemu_driver after calling virCheckFlags().
virDomainVcpuPinDefFree() does not free def->cputune.vcpupin if nvcpupin
is 0, and does not set def->cputune.vcpupin to NULL.
If we set nvcpupin to 0 but do not free vcpupin, vcpupin will not be freed
when vm->def is freed.
Use VIR_FREE() instead of virDomainVcpuPinDefFree() to free the memory
and set def->cputune.vcpupint to NULL.
When building libvirt without libvirtd, we will receive the following error
message:

./src/.libs/libvirt.so: undefined reference to `numa_available'
./src/.libs/libvirt.so: undefined reference to `numa_max_node'
collect2: ld returned 1 exit status
The reason is that: we check numactl only when building qemu driver, and qemu
driver will not be built when bulding without libvirtd. So with_numactl's
value is check and we will not link libnuma.so.
In the other function, we call numa_available() and numa_max_node() only
when HAVE_NUMACTL is 1. We should do the same check in the function nodeGetMemoryStats().
If qemu supports multi function PCI device, the format of the PCI address passed
to qemu is "bus=pci.0,multifunction=on,addr=slot.function".
If qemu does not support multi function PCI device, the format of the PCI address
passed to qemu is "bus=pci.0,addr=slot".
Hot pluging/unpluging multi PCI device is not supported now. So the function
of hotplugged PCI device must be 0. When we hot unplug it, we should set release
all functions in the slot.
We save all used PCI address in the hash table. The key is generated by domain,
bus and slot now. We will support multi function PCI device, so the key should
be generated by domain, bus, slot and function.
We do not support to hot unplug multi function PCI device now. If the device is
one function of multi function PCI device, we shoul not allow to hot unplugg
it.
There is no need to redefine _GNU_SOURCE in tests that occur after
gl_INIT, since that macro already AC_DEFINE'd it for us.

This patch does the following things:
1. The return value of cmdSchedInfoUpdate() can be -1, 0 and 1. So the
type of return value should be int not bool.(This function is not a
entry of a virsh command, but the name of this function likes cmdXXX)
2. The type of cmdSchedinfo()'s, cmdFreecell()'s, cmdPoolList()'s and
cmdVolList()'s return value is bool not int, so change the type of
variable ret_val, func_ret and functionReturn.
3. Add a variable functionReturn for cmdMigrate(), cmdAttachInterface(),
cmdDetachInterface(), cmdAttachDisk() and cmdDetachDisk() to save the
return value.
4. Change the type of variable ret in the function cmdAttachDevice(),
cmdDetachDevice(), cmdUpdateDevice(), cmdAttachInterface(),
cmdDetachInterface(), cmdAttachDisk() and cmdDetachDisk() to int, as
we use it to save the return value of virXXX() and the type of virXXX()'s
return value is int not bool.
5. Do some cleanup when virBuff.error is 1.
The bug 1-4 were introduced by commit b56fa5bb.
Steps to reproduce this bug:
1. # cat net.xml # 00:03.0 has been used
<interface type='network'>
<mac address='52:54:00:04:72:f3'/>
<source network='default'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>
2. # virsh attach-device vm1 net.xml
error: Failed to attach device from net.xml
error: internal error unable to reserve PCI address 0:0:3
3. # virsh attach-device vm1 net.xml
error: Failed to attach device from net.xml
error: internal error unable to execute QEMU command 'device_add': Device 'rtl8139' could not be initialized
The reason of this bug is that: we can not reserve PCI address 0:0:3 because it has
been used, but we release PCI address when we reserve it failed.
When buf->error is 1, we do not return buf->content in the function
virBufferContentAndReset(). So we should free buf->content when
vsnprintf() failed.
This patch does the following two things:
1. hold an extra reference while handling watchdog event
If the domain is not persistent, and qemu quits unexpectedly before
calling processWatchdogEvent(), vm will be freed and the function
processWatchdogEvent() will be dangerous.
2. unlock qemu driver and vm before returning from processWatchdogEvent()
When the function processWatchdogEvent() failed, we only free wdEvent,
but forget to unlock qemu driver and vm, free dumpfile.
We do not lock qemu_driver when calling virThreadPoolNew(). If it failed,
we will unlock qemu_driver. It is dangerous.
We may use this pool during auto starting domains. So we must create it before
calling qemuAutostartDomains(). Otherwise, libvirtd will crash.
commit d4601696 introduces two more generated files: esx_vi.generated.h
and esx_vi.generated.h. But we do not include them into dist file.
It will break building if using dist file to build.
The libexec program libvirt_iohelper is only for libvirtd. If we build rpm

We should bind pci device to original driver when pciBindDeviceToStub() failed.
If the pci device is not bound to any driver before calling pciBindDeviceToStub(),
we should only unbind it from pci-stub. If it is bound to pci-stub, we should not
unbind it from pci-stub.
This patch do the following things:
1. rename the function as 'Unbind' is better than 'UnBind'.
2. pciUnbindDeviceFromStub() will be used in the function pciBindDeviceToStub() in
next patch. Float it up, instead of having to have a forward declaration
If strdup("x509dname") or strdup("saslUsername") success, but
strdup(x509dname) or strdup(saslUsername) failed, subject->nidentity
is not the num elements of subject->identities, and we will leak some
memory.
We create a temporary file to save memory, and we will remove it after reading
memory to buffer. But we free the variable that contains the temporary filename
before we remove it. So we should free tmp after unlinking it.
If qemu quited unexpectedly when we call qemuMonitorJSONHMP(),
libvirt will crash.
Steps to reproduce this bug:
1. use gdb to attach libvirtd, and set a breakpoint in the function
qemuMonitorSetCapabilities()
2. start a vm
3. let the libvirtd to run until qemuMonitorJSONSetCapabilities() returns.
4. kill the qemu process
5. continue running libvirtd

We have reported error in the function prepareCall(), and
the error is not only OOM error. So we should not report
OOM error in the function call() when prepareCall() failed.
Steps to reproduce this bug:
# cat test.sh
#! /bin/bash -x
virsh start domain
sleep 5
virsh qemu-monitor-command domain 'cpu_set 2 online' --hmp
# while true; do ./test.sh ; done
Then libvirtd will crash.
The reason is that:
we add a reference of obj when we open the monitor. We will reduce this
reference when we free the monitor.
If the reference of monitor is 0, we will free monitor automatically and
the reference of obj is reduced.
But in the function qemuDomainObjExitMonitorWithDriver(), we reduce this
reference again when the reference of monitor is 0.
It will cause the obj be freed in the function qemuDomainObjEndJob().
Then we start the domain again, and libvirtd will crash in the function
virDomainObjListSearchName(), because we pass a null pointer(obj->def->name)
to strcmp().

QEMUD_CMD_FLAG_PCI_MULTIBUS should be set in the function

testCompareXMLToArgvFiles() in qemuxml2argvtest.c.
So we should set QEMUD_CMD_FLAG_PCI_MULTIBUS in the function

If the memory of guest OS is changed constantly, the live migration
can not be ended ever for ever.
We can use the command 'virsh migrate-setmaxdowntime' to control the
live migration. But the value of maxdowntime is diffcult to calculate
because it depends on the transfer speed of network and constantly
changing memroy size. We need a easy way to control the live migration.
This patch adds the support of forcing guest to suspend at timeout.
With this patch, when we migrate the guest OS, we can specify a
timeout. If the live migration timeouts, auto-suspend the guest OS,
where the migration will complete offline.
Steps to reproduce this bug:
1. service libvirtd start
2. virsh start <domain>
3. kill -STOP $(cat /var/run/libvirt/qemu/<domain>.pid)
4. service libvirtd restart
5. kill -9 $(cat /var/run/libvirt/qemu/<domain>.pid)
Then libvirtd will core dump or be in deadlock state.
Make sure that json is built into libvirt and the version
of qemu is newer than 0.13.0.
The reason of libvirtd cores dump is that:
We add vm->refs when we alloc the memory, and decrease it
in the function qemuHandleMonitorEOF() in other thread.
We add vm->refs in the function qemuConnectMonitor() and
decrease it when the vm is inactive.
The libvirtd will block in the function qemuMonitorSetCapabilities()
because the vm is stopped by signal SIGSTOP. Now the vm->refs is 2.
Then we kill the vm by signal SIGKILL. The function
qemuMonitorSetCapabilities() failed, and then we will decrease vm->refs
in the function qemuMonitorClose().
In another thread, mon->fd is broken and the function
qemuHandleMonitorEOF() is called.
If qemuHandleMonitorEOF() decreases vm->refs before qemuConnectMonitor()
returns, vm->refs will be decrease to 0 and the memory is freed.
We will call qemudShutdownVMDaemon() as qemuConnectMonitor() failed.
The memory has been freed, so qemudShutdownVMDaemon() is too dangerous.
We will reference NULL pointer in the function virDomainConfVMNWFilterTeardown():
=============
void
virDomainConfVMNWFilterTeardown(virDomainObjPtr vm) {
int i;
if (nwfilterDriver != NULL) {
for (i = 0; i < vm->def->nnets; i++)
virDomainConfNWFilterTeardown(vm->def->nets[i]);
}
}
============
vm->def->nnets is not 0 but vm->def->nets is NULL(We don't set vm->def->nnets
to 0 when we free vm).
We should add an extra reference of vm to avoid vm to be deleted if
qemuConnectMonitor() failed.
