Drivers load running persistent and transient domain configs before
inactive persistent domain configs, however only the latter would set a
domain's autostart flag. This mismatch between the loaded and on-disk
state could later cause problems with "virsh autostart":
# virsh autostart example
error: Failed to mark domain example as autostarted
error: Failed to create symlink '/etc/libvirt/qemu/autostart/example.xml to '/etc/libvirt/qemu/example.xml': File exists
This patch ensures the autostart flag is set correctly even when the
domain is already defined.

commit f0443765 which replaced openvz_readline to getline(3)
broke OpenVZ driver as it changed semantics of EOF-handling
when parsing OpenVZ configuration.
There're several other issues reported with current OpenVZ driver:
#1: unclear error message when parsing "CPUS=" line
#2: openvz driver goes into crashing loop
#3: "NETIF=" line in configuration is not parsed correctly
#4: aborts even when optional parameter is missing
#5: there's a potential memory leak
This updated patch to fix #[145]. This patch does not fix #[23]
as I haven't verified these yet, but this at least got me to run
OpenVZ on libvirt once again.
Originally most of libvirt domain-specific calls were blocking
during a migration.
A new mechanism to allow specific calls (blkstat/blkinfo) to be
executed in such condition has been implemented.
In the long term it'd be desirable to get a more general
solution to mark further APIs as migration safe, without needing
special case code.
* src/qemu/qemu_migration.c: add some additional job signal
flags for doing blkstat/blkinfo during a migration
* src/qemu/qemu_domain.c: add a condition variable that can be
used to efficiently wait for the migration code to clear the
signal flag
* src/qemu/qemu_driver.c: execute blkstat/blkinfo using the
job signal flags during migration

Users often edit XML file stored in configuration directory
thinking of modifying a domain/network/pool/etc. Thus it is wise
to let them know they are using the wrong way and give them hint.
Commit 36deff04 introduced a regression due to which virsh is not able
to log to a file - msg_buf was changed from an array to a pointer
without corresponding change to usage of "sizeof()".

Reattaching pci device back to host without destroying guest or
detaching device from guest would cause host to crash. This patch adds
a check before doing device reattach. If the device is being assigned
to guest, libvirt refuses to reattach device to host. The patch only
works for Xen, for it just checks xenstore to get pci device
information.

gcc 4.6 warns when a variable is initialized but isn't used afterwards:
vmware/vmware_driver.c:449:18: warning: variable 'vmxPath' set but not used [-Wunused-but-set-variable]
This patch fixes these warnings. There are still 2 offending files:
- vbox_tmpl.c: the variable is used inside an #ifdef and is assigned several
times outside of #ifdef. Fixing the warning would have required wrapping
all the assignment inside #ifdef which hurts readability.
vbox/vbox_tmpl.c: In function 'vboxAttachDrives':
vbox/vbox_tmpl.c:3918:22: warning: variable 'accessMode' set but not used [-Wunused-but-set-variable]

This patch enables the relative backing file path support provided by
qemu-img create.
If a relative path is specified for the backing file, it is converted
to an absolute path using the storage pool path. The absolute path is
used to verify that the backing file exists. If the backing file exists,
the relative path is allowed and will be provided to qemu-img create.
Currently libvirt's default logging is limited and it is difficult to
determine what was happening when a proglem occurred (especially on a
machines where one don't know the detail.) This patch helps to do that
by making additional logging available for the following events:
creating/defining/undefining domains
creating/defining/undefining/starting/stopping networks
creating/defining/undefining/starting/stopping storage pools
creating/defining/undefining/starting/stopping storage volumes.

The current description suggests that you always have to provide
a valid typeVer pointer. But if you want only the libvirt version
it's also possible to set type and typeVer to NULL to skip the
hypervisor part.
This patch introduces a new libvirt API (virDomainSetMemoryFlags) and
a flag (virDomainMemoryModFlags).

When compiling libvirt with GCC 3.4.6 the following warning is being triggered quite a lot:
util/memory.h:60: warning: declaration of 'remove' shadows a global declaration
/usr/include/stdio.h:175: warning: shadowed declaration is here
Fix this by renaming the parameter to 'toremove'.
Depending if the qemu binary supports multiple pci-busses, the device
options will contain "bus=pci" or "bus=pci.0".
Only x86_64 and i686 seem to have support for multiple PCI-busses. When
a guest of these architectures is started, set the
QEMUD_CMD_FLAG_PCI_MULTIBUS flag.

I added a host definition to a network definition:
<network>
<name>Lokal</name>

<bridge name='virbr1' stp='on' delay='0' />

<host mac='23:74:00:03:42:02' name='somevm' ip='192.168.180.10' />
</dhcp>
</ip>
</network>
But due to the wrong if-statement the argument --dhcp-hostsfile doesn't get
added to the dnsmasq command. The patch below fixes it for me.
While not technically a double free (since VIR_FREE NULLs the
pointer), this is unnecessary extra code.
This crept in when the function was converted from virRun to virCommand.

Changes common to all network disks:
-Make source name optional in the domain schema, since NBD doesn't use it
-Add a hostName type to the domain schema, and use it instead of genericName, which doesn't include .
-Don't leak host names or ports
-Set the source protocol in qemuParseCommandline

When dumping a domain, it's reasonable to save dump-file in raw format
if dump format is misconfigured or the corresponding compress program
is not available rather then fail dumping.
When we set migrate_speed by json, we receive the following
error message:
libvirtError: internal error unable to execute QEMU command
'migrate_set_speed': Invalid parameter type, expected: number
The reason is that: the arguments of migrate_set_speed
by json is json number, not json string.
