a267f01532 openvz: Check errors from virSocketAddrFormat
Commit id 'a4e86390' modified the command line to allow --ipadd multiple
times; however, it did not account for the condition where a NULL is
returned which will could lead to some interesting errors with multiple
--ipadd's without parameters.

a4e8639068 Openvz --ipadd can be provided multiple times
Vzctl man page says that --ipadd can be provided multiple times to add
several IP addresses. Looping over the configured ip addresses to add
one --ipadd for each. This would even handle the multiple IPs handled

virReportSystemError is reserved for reporting system errors, calling it
with VIR_ERR_* error codes produces error messages that do not make any

e3c626a61d openvz: fixed two memory leaks on migration code
The first one occurs in openvzDomainMigratePrepare3Params() where in
case no remote uri is given, the distant hostname is used. The name is
obtained via virGetHostname() which require callers to free the
returned value.
The second leak lies in openvzDomainMigratePerform3Params(). There's a
virCommand used later. However, at the beginning of the function
virCheckFlags() is called which returns. So the command created was
leaked.

b9dd878ff8 util: make it easier to grab only regular command exit
Auditing all callers of virCommandRun and virCommandWait that
passed a non-NULL pointer for exit status turned up some
interesting observations.  Many callers were merely passing
a pointer to avoid the overall command dying, but without
caring what the exit status was - but these callers would
be better off treating a child death by signal as an abnormal
exit.  Other callers were actually acting on the status, but
not all of them remembered to filter by WIFEXITED and convert
with WEXITSTATUS; depending on the platform, this can result
in a status being reported as 256 times too big.  And among
those that correctly parse the output, it gets rather verbose.
Finally, there were the callers that explicitly checked that
the status was 0, and gave their own message, but with fewer
details than what virCommand gives for free.

So the best idea is to move the complexity out of callers and
into virCommand - by default, we return the actual exit status
already cleaned through WEXITSTATUS and treat signals as a
failed command; but the few callers that care can ask for raw
status and act on it themselves.

d24677090f maint: avoid 'const fooPtr' in domain_conf
'const fooPtr' is the same as 'foo * const' (the pointer won't
change, but it's contents can).  But in general, if an interface
is trying to be const-correct, it should be using 'const foo *'
(the pointer is to data that can't be changed).

Fix up offenders in src/conf/domain_conf, and their fallout.

Several things to note: virObjectLock() requires a non-const
argument; if this were C++, we could treat the locking field
as 'mutable' and allow locking an otherwise 'const' object, but
that is a more invasive change, so I instead dropped attempts
to be const-correct on domain lookup.  virXMLPropString and
friends require a non-const xmlNodePtr - this is because libxml2
is not a const-correct library.  We could make the src/util/virxml
wrappers cast away const, but I figured it was easier to not
try to mark xmlNodePtr as const.  Finally, virDomainDeviceDefCopy
was a rather hard conversion - it calls virDomainDeviceDefPostParse,
which in turn in the xen driver was actually modifying the domain
outside of the current device being visited.  We should not be
adding a device on the first per-device callback, but waiting until
after all per-device callbacks are complete.

1c6d4ca557 Separate internal node device APIs from public API
The individual hypervisor drivers were directly referencing
APIs in src/nodeinfo.c in their virDriverPtr struct. Separate
these methods, so there is always a wrapper in the hypervisor
driver. This allows the unused virConnectPtr args to be

ACL checks will only be performed on invocations that are
directly associated with public API usage.

ead630319d Separate virGetHostname() API contract from driver APIs
Currently the virGetHostname() API has a bogus virConnectPtr
parameter. This is because virtualization drivers directly
reference this API in their virDriverPtr tables, tieing its
API design to the public virConnectGetHostname API design.

This also causes problems for access control checks since
these must only be done for invocations from the public
API, not internal invocation.

Remove the bogus virConnectPtr parameter, and make each
hypervisor driver provide a dedicated function for the
driver API impl. This will allow access control checks
to be easily inserted later.

482e5f159c virCaps: get rid of defaultConsoleTargetType callback
This patch refactors various places to allow removing of the
defaultConsoleTargetType callback from the virCaps structure.

A new console character device target type is introduced -
VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_NONE - to mark that no type was
specified in the XML. This type is at the end converted to the standard
VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_SERIAL. Other types that are
different from this default have to be processed separately in the
device post parse callback.

Without configuration the KVM mac prefix is used by default. I chose it

This gets rid of the parameter in favor of using the new callback
infrastructure to do the same stuff.

driver and moves the check from the parser to a new validation method in

43b99fc4c0 conf: Add post XML parse callbacks and prepare for cleaning of virCaps
This patch adds instrumentation that will allow hypervisor drivers to
fill and validate domain and device definitions after parsed by the XML
parser.

With this patch, after the XML is parsed, a callback to the driver is
issued requesting to fill and validate driver specific details of the
configuration. This allows to use sensible defaults and checks on a per
driver basis at the time the XML is parsed.

Two callback pointers are stored in the new virDomainXMLConf object:
* virDomainDeviceDefPostParseCallback (devicesPostParseCallback)
  - called for a single device parsed and for every single device in a
    domain config. A virDomainDeviceDefPtr is passed along with the
    domain definition and virCaps.

* virDomainDefPostParseCallback, (domainPostParseCallback)
  - A callback that is meant to process the domain config after it's
  parsed.  A virDomainDefPtr is passed along with virCaps.

Both types of callbacks support arbitrary opaque data passed for the
callback functions.

Errors may be reported in those callbacks resulting in a XML parsing
failure.

27cf98e2d1 virCaps: conf: start splitting out irrelevat data
The virCaps structure gathered a ton of irrelevant data over time that.
The original reason is that it was propagated to the XML parser
functions.

This patch aims to create a new data structure virDomainXMLConf that
will contain immutable data that are used by the XML parser. This will
allow two things we need:

1) Get rid of the stuff from virCaps

2) Allow us to add callbacks to check and add driver specific stuff
after domain XML is parsed.

This first attempt removes pointers to private data allocation functions
to this new structure and update all callers and function that require
them.

b1c88c1476 capabilities: defaultConsoleTargetType can depend on architecture
For S390, the default console target type cannot be of type 'serial'.
It is necessary to at least interpret the 'arch' attribute
value of the os/type element to produce the correct default type.

Therefore we need to extend the signature of defaultConsoleTargetType
to account for architecture. As a consequence all the drivers
supporting this capability function must be updated.

Despite the amount of changed files, the only change in behavior is
that for S390 the default console target type will be 'virtio'.

N.B.: A more future-proof approach could be to to use hypervisor
specific capabilities to determine the best possible console type.
For instance one could add an opaque private data pointer to the
virCaps structure (in case of QEMU to hold capsCache) which could
then be passed to the defaultConsoleTargetType callback to determine
the console target type.
Seems to be however a bit overengineered for the use case...

I noticed this while auditing all calls to virCommandRun that request
an exit status from virCommandRun. Two functions in the openvz driver

  openvzDomainGetBarrierLimit
  openvzDomainSetBarrierLimit

request an exit status from virCommandRun (thus assuring that
virCommandRun won't log any errors just due to a non-0 exit status),
but then fail to examine that exit status. This could result in the
functions believing that the call to "vzlist" was successful, even
though it may have encountered an error.

768007aedc maint: don't permit format strings without %
Any time we have a string with no % passed through gettext, a
translator can inject a % to cause a stack overread.  When there
is nothing to format, it's easier to ask for a string that cannot
be used as a formatter, by using a trivial "%s" format instead.

In the past, we have used --disable-nls to catch some of the
offenders, but that doesn't get run very often, and many more
uses have crept in.  Syntax check to the rescue!

The syntax check can catch uses such as
virReportError(code,
               _("split "
                 "string"));
by using a sed script to fold context lines into one pattern
space before checking for a string without %.

33dc8cf018 drivers: Implement virListAllDomains for drivers using virDomainObj
This patch adds support for listing all domains into drivers that use
the common virDomainObj implementation: libxl, lxc, openvz, qemu, test,
uml, vmware.

For drivers that don't support managed save images the guests are
treated as if they had none, so filtering guests that do have such an
image on this driver succeeds and produces 0 results.

4888f0fb56 xml: use better types for memory values
Using 'unsigned long' for memory values is risky on 32-bit platforms,
as a PAE guest can have more than 4GiB memory.  Our API is
(unfortunately) locked at 'unsigned long' and a scale of 1024, but
the rest of our system should consistently use 64-bit values,
especially since the previous patch centralized overflow checking.

for memory.  Change hugepage_backed to a bool.

9f748277bb Fixed URI parsing
Function xmlParseURI does not remove square brackets around IPv6
address when parsing. One of the solutions is making wrappers around
functions working with xmlURI*. This assures that uri->server will be
always properly assigned and it doesn't have to be changed when used
on some new place in the code.
For this purpose, functions virParseURI and virSaveURI were
added. These function are wrappers around xmlParseURI and xmlSaveUri
respectively.
Also there is one new syntax check function to prohibit these functions
anywhere else.

File changes:
 - src/util/viruri.h        -- declaration
 - src/util/viruri.c        -- definition
 - src/libvirt_private.syms -- symbol export

Add a new API virDomainShutdownFlags and define:

    VIR_DOMAIN_SHUTDOWN_ACPI_POWER_BTN = (1 << 0),
    VIR_DOMAIN_SHUTDOWN_GUEST_AGENT    = (1 << 1),

Also define some flags for the reboot API

    VIR_DOMAIN_REBOOT_DEFAULT        = 0,
    VIR_DOMAIN_REBOOT_ACPI_POWER_BTN = (1 << 0),
    VIR_DOMAIN_REBOOT_GUEST_AGENT    = (1 << 1),

Although these two APIs currently have the same flags, using
separate enums allows them to expand separately in the future.

209c2880b9 Fix default console type setting

OS type.

failure to the caller, without wasting efforts to check the call.

4b15aad0d6 openvz: Handle getline failures in openvzReadConfigParam properly
The regression fix in 3aab7f2d6b altered the error handling.
getline returns -1 on failure to read a line (including EOF). The

treated EOF as not-found. The current getline version treats all
getline failures as not-found.

failures.

3aab7f2d6b openvz: Fix regression in config file parsing
As reported by Diego Blanco in

  https://bugzilla.redhat.com/show_bug.cgi?id=702602

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.

b046c55d40 Implement domain state reason
Only in drivers which use virDomainObj, drivers that query hypervisor
for domain status need to be updated separately in case their hypervisor
supports this functionality.

The reason is also saved into domain state XML so if a domain is not
running (i.e., no state XML exists) the reason will be lost by libvirtd
restart. I think this is an acceptable limitation.

34639a3f6b domain: Require <init> for container guests
Use capabilities to allow a driver to register a default <init> if none
is specified in the XML. Openvz was already open-coding this to be /sbin/init

LXC currently falls over if no init is specified, so an explicit error is
an improvement IMO.

(Side note: I don't think we can set a default value for LXC. If we use
/sbin/init but the user doesn't specify a separate root FS for their guest,
the container will rerun the host's init which can be traumatic :). For
virt-install I'm thinking of defaulting to /sbin/init if a root FS has
been specified, otherwise require the user to manually specify <init>)

b65f37a4a1 libvirt,logging: cleanup VIR_XXX0()
These VIR_XXXX0 APIs make us confused, use the non-0-suffix APIs instead.

How do these coversions works? The magic is using the gcc extension of ##.
When __VA_ARGS__ is empty, "##" will swallow the "," in "fmt," to
avoid compile error.

example: origin				after CPP
	high_level_api("%d", a_int)	low_level_api("%d", a_int)
	high_level_api("a  string")	low_level_api("a  string")

About 400 conversions.

8 special conversions:
VIR_XXXX0("") -> VIR_XXXX("msg") (avoid empty format) 2 conversions
VIR_XXXX0(string_literal_with_%) -> VIR_XXXX(%->%%) 0 conversions
VIR_XXXX0(non_string_literal) -> VIR_XXXX("%s", non_string_literal)
  (for security) 6 conversions

68ea80cfdd maint: rename virBufferVSprintf to virBufferAsprintf
We already have virAsprintf, so picking a similar name helps for
seeing a similar purpose.  Furthermore, the prefix V before printf
generally implies 'va_list', even though this variant was '...', and
the old name got in the way of adding a new va_list version.

global rename performed with:

$ git grep -l virBufferVSprintf \
  | xargs -L1 sed -i 's/virBufferVSprintf/virBufferAsprintf/g'

then revert the changes in ChangeLog-old.

When an openvz domain is defined with virDomainDefineXML,
domain id is set to -1. A call to virDomainGetInfo after
starting the domain would then fail because this invalid
id is passed to openvzGetProcessInfo.

21adf03c2d Qemu Monitor API entry point.
Add the library entry point for the new virDomainQemuMonitorCommand()
entry point.  Because this is not part of the "normal" libvirt API,
it gets its own header file, library file, and will eventually
get its own over-the-wire protocol later in the series.

Changes since v1:
 - Go back to using the virDriver table for qemuDomainMonitorCommand, due to
   linking issues
 - Added versioning information to the libvirt-qemu.so

Changes since v2:
 - None

Changes since v3:
 - Add LGPL header to libvirt-qemu.c
 - Make virLibConnError and virLibDomainError macros instead of function calls

Changes since v4:
 - Move exported symbols to libvirt_qemu.syms

460ca88b98 libvirt: introduce domainCreateWithFlags API
Persistent domain creation needs the same features as transient
domains, but virDomainCreate lacks the flags argument present in
virDomainCreateXML.  virDomainCreateFlags is already claimed as
a public enum, so we have to break convention and expose
virDomainCreateWithFlags.

* include/libvirt/libvirt.h.in (virDomainCreateWithFlags): Add.
* src/driver.h (virDrvDomainCreateWithFlags): Internal API.
* src/libvirt.c (virDomainCreateWithFlags): Glue public API to
driver API.

29045d88ed Fix build of openvz on RHEL-5.
When building libvirt on RHEL-5, I saw this error:

cc1: warnings being treated as errors
openvz/openvz_conf.c: In function 'openvzGetVPSUUID':
openvz/openvz_conf.c:835: warning: 'saveptr' may be used uninitialized in this function
make[3]: *** [libvirt_driver_openvz_la-openvz_conf.lo] Error 1

gcc in RHEL-5 gets upset about this usage of strtok_r (even though
it is perfectly valid).  Just set *saveptr to NULL at the
start to quiet it down.

15c647a91e Add managed save API entry points
virDomainManagedSave() is to be run on a running domain. Once the call
complete, as in virDomainSave() the domain is stopped upon completion,
but there is no restore counterpart as any order to start the domain
from the API would load the state from the managed file, similary if
the domain is autostarted when libvirtd starts.
Once a domain has restarted his managed save image is destroyed,
basically managed save image can only exist for a stopped domain,
for a running domain that would be by definition outdated data.

* include/libvirt/libvirt.h.in src/libvirt.c src/libvirt_public.syms:
  adds the new entry points virDomainManagedSave(),
  virDomainHasManagedSaveImage() and virDomainManagedSaveRemove()
