4edf01c92c Explicitly format the isa-fdc controller for newer q35 machines
Since QEMU commit ea96bc6 [1]:
i386: drop FDC in pc-q35-2.4+ if neither it nor floppy drives are wanted
the floppy controller is no longer implicit.

Specify it explicitly on the command line if the machine type version
is 2.4 or later.

Note that libvirt's floppy drives do not result in QEMU implying the
controller, because libvirt uses if=none instead of if=floppy.

4ef21ec192 Separate isa-fdc options generation
For the implicit controller, we set them via -global.
Separating them will allow reuse for explicit fdc controller as well.

No functional impact apart from one extra allocation.

f92f31213a storage: Fix regression in storagePoolUpdateAllState
Commit 2a31c5f0 introduced support for storage pool state XMLs, however
it also introduced a regression:

if (!virstoragePoolObjIsActive(pool)) {
    virStoragePoolObjUnlock(pool);
    continue;
}

The idea behind this was that since we've got state XMLs and the pool
wasn't marked as active by autostart routine (if the autostart flag had been
set earlier), the pool is inactive and we can leave it be and continue with
other pools. However, filesystem type pools like fs,dir, possibly netfs are
supposed to be active if the filesystem is mounted on the host. And this is
exactly where the regression occurs, e.g. pool type 'dir' which has been
previously destroyed and marked as !autostart gets filtered out
by the condition above.
The resolution should be simply to remove the condition completely,
all pools will get their 'active' flag updated by check callback and if
they do not support such callback, the logic doesn't change and such
pools will be inactive by default (e.g. RBD, even if a state XML exists).

e8c5f61e91 util: bitmap: Don't alloc overly large binary bitmaps
Optimize the virBitmap to array-of-char bitmap conversion by skipping
trailing zero bytes.

This also fixes a regression when requesting iothread information from a
live VM since after commit 825df8c315 the
bitmap returned from virProcessGetAffinity is too big to be formatted
properly via RPC. A user would get the following error:

0b3fcfb1ea qemu: move the guest status check before agent config and status check
When use setvcpus command with --guest option to a offline vm,
we will get error:

 # virsh setvcpus test3 1 --guest
 error: Guest agent is not responding: QEMU guest agent is not connected

However guest is not running, agent status could not be connected.
In this case, report domain is not running will be better than agent is
not connected. Move the guest status check more early to output error to
point out guest status is not right.

Also from the logic, a running vm is a basic requirement to use
agent, we cannot use agent if vm is not running.

302146b16d lxc: Don't pass a local variable address randomly
So, recently I was testing the LXC driver. You know, startup some
domains. But to my surprise, I was not able to start a single one:

  virsh # start --console test
  error: Reconnected to the hypervisor
  error: Failed to start domain test
  error: internal error: guest failed to start: unexpected exit status 125

So I've start digging. It turns out, that in virExec(), when I printed
out the @cmd, I got strange values: *(cmd->outfdptr) was certainly not
valid FD number: it has random value of several millions. This
obviously made prepareStdFd(childout, STDOUT_FILENO) fail (line 611).
But outfdptr is set in virCommandSetOutputFD(). The only place within
LXC driver where the function is called is in
virLXCProcessBuildControllerCmd(). If you take a closer look at the
function it looks like this:

static virCommandPtr
virLXCProcessBuildControllerCmd(virLXCDriverPtr driver,
                                ..
                                int logfd,
                                const char *pidfile)
{
    ...
    virCommandSetOutputFD(cmd, &logfd);
    virCommandSetErrorFD(cmd, &logfd);
    ...
}

Yes, you guessed it. @logfd is passed into the function by value.
However, in the function we try to get its address (an address of a
local variable) which is no longer valid once function is finished and
stack is cleaned. Therefore when cmd->outfdptr is evaluated at any
point after this function, we may get a random number, depending on
what's currently on the stack. Of course, this may work sometimes too
- it depends on the compiler how it arranges the code, when the stack
is wiped out.

In order to fix this, lets pass a pointer to @logfd instead of
figuring out (wrong) its value in a function.

The bug was introduced in e1de5521.

04597f8f0d libxl: Set def->vcpus after successfully modifying live vcpu count
def->vcpus was never updated after successfully changing the live
vcpu count of a domain. Subsequent queries for vcpu info would
return incorrect results.  E.g.:

virsh vcpucount test

maximum      live           4

maximum      live           4
current      config         4
current      live           4

After patch, live current config is reported correctly:

virsh vcpucount test
maximum      config         4
maximum      live           4
current      config         4
current      live           2

While fixing this, noticed that the live config was not saved
to cfg->stateDir via virDomainSaveStatus. Save the live config
and change error handling of virDomainSave{Config,Status} to
log a message via VIR_WARN, instead of failing the entire
DomainSetVcpusFlags operation.

https://bugzilla.redhat.com/show_bug.cgi?id=1232606

Since an mpath pool contains all the Multipath devices on a host, allowing
more than one defined on a host at a time should be disallowed under the
policy of disallowing duplicate source pools for the host.

Adjust to docs to clarify the Multipath target path value usage for both
the storage driver (only 1 pool per host) and formatstorage references
(ignore the target element in favor of the default target mapping of

c79ebf53b5 conf: Validate disk lun using correct types
https://bugzilla.redhat.com/show_bug.cgi?id=1201143

The formatdomain.html description for <disk> device 'lun' indicates that
it must be either a type 'block' or type 'network' with protocol 'iscsi';
however, we did not make that check until domain startup.

This caused issues for virt-manager which had an unexpected failure at
run time rather config time.

This patch adds a check in post part disk device checking for the specific
and supported lun types as well as adjusting the test failure to be for
parse config rather than run time.

Libvirt periodically refreshes all volumes in a storage pool, including

While cloning a storage volume from parent, we drop pool locks. Subsequent

to corrupt images.
Fix: Introduce a shadow volume that isolates the volume object under refresh

9a12b6cd8c qemu: ignore assumptions about hotplug requirement when address is from config
Certain PCI buses don't support hotplug, and when automatically
assigning PCI addresses for devices, libvirt is very conservative in
its assumptions about whether or not a device will need to be
hotplugged/unplugged in the future. But if the user manually assigns
an address, they likely are aware of any hotplug requirements of the
device (or at least they should be).

In short, after this patch, automatically PCI address assignment will
assume that the device must be plugged in to a hot-pluggable slot, but
manually assignment can place the device in any bus that is
compatible, regardless of whether or not it supports hotplug. If the
user makes a mistake and plugs the device into a bus that doesn't
support hotplug, then later tries to do a hot-unplug, qemu will give
an appropriate error.

(in the future we may want to add a "hotpluggable" attribute to all
devices, with default being "yes" for autoassign, and "no" for manual
assign).

1e15be1bbc qemu: always permit PCI devices to be manually assigned to a PCIe bus
When support for the pcie-root and dmi-to-pci-bridge buses on a Q35
machinetype was added, I was concerned that even though qemu at the
time allowed plugging a PCI device into a PCIe port, that it might not
be supported in the future. To prevent painful backtracking in the
possible future where this happened, I disallowed such connections
except in a few specific cases requested by qemu developers (indicated
in the code with the flag VIR_PCI_CONNECT_TYPE_EITHER_IF_CONFIG).

Now that a couple years have passed, there is a clear message from
qemu that there is no danger in allowing PCI devices to be plugged
into PCIe ports. This patch eliminates
VIR_PCI_CONNECT_TYPE_EITHER_IF_CONFIG and changes the code to always
allow PCI->PCIe or PCIe->PCI connection *when the PCI address is
specified in the config. (For newly added devices that haven't yet
been given a PCI address, the auto-placement still prefers using the
correct type of bus).

except pci-root and pcie-root has a check for index > 0 (since only
those two can have index==0), and the function should never be called
for those two anyway. If we move the check for !pci[e]-root to the top
of the pci case, then we can move the check for index > 0 out of the
individual model cases. This will save repeating that check for the
three new controller models about to be added.

70d75ffc79 qemuBuildMemoryBackendStr: Honour passed @pagesize
So far the argument has not much meaning and was practically ignored.
This is not good since when doing memory hotplug, the size of desired
hugepage backing is passed in that argument. Taking closer look at the
tests I'm fixing reveals the bug. For instance, while the following is
in the test:

    <memory model='dimm'>
      <source>
        <nodemask>1-3</nodemask>
        <pagesize unit='KiB'>4096</pagesize>
      </source>
      <target>
        <size unit='KiB'>524287</size>
        <node>0</node>
      </target>
      <address type='dimm' slot='0' base='0x100000000'/>
    </memory>

the generated commandline corresponding to this XML was:

    -object memory-backend-ram,id=memdimm0,size=536870912,\
    host-nodes=1-3,policy=bind

Have you noticed? Yes, memory-backend-ram! Nothing can be further away
from the right answer. The hugepage backing is requested in the XML
and we happily ignore it. This is just not right. It's
memory-backend-file which should have been used:

    -object memory-backend-file,id=memdimm0,prealloc=yes,\
    mem-path=/dev/hugepages4M/libvirt/qemu,size=536870912,\
    host-nodes=1-3,policy=bind

The problem is, that @pagesize passed to qemuBuildMemoryBackendStr
(where this part of commandline is built) was ignored. The hugepage to
back memory was searched only and only by NUMA nodes pinning. This
works only for regular guest NUMA nodes.

Then, I'm changing the hugepages size in the test XMLs too. This is
simply because in the test suite we create dummy mount points just for
2M and 1G hugepages. And in the test 4M was requested. I'm sticking to
2M, but 1G should just work too.

f8e9deb1d4 qemuBuildMemoryBackendStr: Fix hugepages lookup process
https://bugzilla.redhat.com/show_bug.cgi?id=1196644

This function constructs the backend (host facing) part of the
memory device.  At the beginning, the configured hugepages are
searched to find the best match for given guest NUMA node.
Configured hugepages can have a @nodeset attribute to specify on
which guest NUMA nodes should be the hugepages backing used.
There is, however, one 'corner case'. Users may just tell 'use
hugepages to back all the nodes'. In other words:

  <memoryBacking>
    <hugepages/>
  </memoryBacking>

  <cpu>
    <numa>
      <cell id='0' cpus='0-1' memory='1024000' unit='KiB'/>
    </numa>
  </cpu>

Our code fails in this case. Well, since there's no @nodeset (nor
any <page/> child element to <hugepages/>) we fail to lookup the
default hugepage size to use.

7cd991b74c json: reject trailing garbage
Yajl 2 has a nice feature that it can be configured whether to
allow multiple JSON objects parsed from a single stream, defaulting
to off.  And yajl 1.0.12 at least provided a way to tell if all
input bytes were parsed, or if trailing bytes remained after a
valid JSON object was parsed.  But we target RHEL 6 yajl 1.0.7,
which has neither of these.  So fake it by always parsing '[...]'
instead, so that trailing garbage either trips up the array parse,
or is easily detected when unwrapping the result.

54dbba5bc3 json: reject javascript comments
We have been allowing javascript style comments in JSON ever
since commit 9428f2c (v0.7.5), but qemu doesn't send them, and
they are not strict JSON.  Reject them for now; if we can later
prove that it is worthwhile, we can reinstate it at that point
(or even make it conditional, by adding a bool parameter to
the libvirt entry point).

f2acaebd40 json: cope with older yajl semantics
Commit ceb496e5 fails on RHEL 6, with yajl 1.0.7, because that
version of yajl returns yajl_status_insufficient_data when the
parser is waiting for the rest of a token (this enum value was
dropped in yajl 2, so we have to wrap it).  It also exposes a
problem where older yajl silently ignores trailing garbage after
a successful parse, so this patch works around that by changing
the testsuite.  Another more invasive patch can add tighter
semantics to json parsing, but this is sufficient for a minimal
clean backport.

While touching this, fix up our error message cleanup. Yajl
documents that error messages produced by yajl_get_error()
MUST be cleaned with yajl_free_error(); this is certainly
true if we were to pass non-NULL allocator callbacks during
yajl_alloc(), but probably harmless in our usage of passing
NULL.  But better safe than sorry.

* src/util/virjson.c (virJSONValueFromString): Allow different
error code.  Use canonical cleanup of error message.
(VIR_YAJL_STATUS_OK): New helper macro.
* tests/jsontest.c (mymain): Wrap text to avoid difference in
trailing garbage handling

In this patch we add VIR_DOMAIN_DEVICE_NET handlers implementation

As soon as we don't support this operation for hypervisor type domains,
we implement this functionality for containers only.

In detach procedure we find network device by MAC address.
Because PrlVmDevNet_GetMacAddress() returns MAC as a UTF-8 encoded
null-terminated string, we use memcmp() to compare it.
Also we remove corresponding virtual network by prlsdkDelNetAdapter call.

As 'configmake.h' defines DATADIR and 'datatypes.h' transitively
includes 'winsock.h' that uses 'DATADIR' as a name for a struct,
it's enough to reorder those.

Even though this might be worked around in gnulib later on, this

treated the input string of "1" as invalid JSON.  It turns out
that YAJL specifically documents that it buffers input, and that
if the last input read could be a prefix to a longer token, then
you have to explicitly tell the parser that the buffer has ended
before that token will be processed.

It doesn't help that yajl 2 renamed the function from what it was

cc99d240f5 libxl: avoid freeing an uninitialised bitmap
If vm->def->cputune.nvcpupin is 0 in libxlDomainSetVcpuAffinities (as
seems to be the case on arm) then the VIR_FREE after cleanup: would be
operating on an uninitialised pointer in map.map.

Fix this by using libxl_bitmap_init and libxl_bitmap_dispose in the
appropriate places (like VIR_FREE, libxl_bitmap_dispose is also
idempotent, so there is no double free on exit from the loop).

libxl_bitmap_dispose is slightly preferable since it also sets
map.size back to 0, avoiding a potential source of confusion.

This fixes the crashes we've been seeing in the Xen automated tests on
ARM.

I had a glance at the handful of other users of libxl_bitmap and none
of them looked to have a similar issue.

Well, if a server is being destructed, all underlying services and
their sockets should disappear with it. But due to bug in our
implementation this is not the case. Yes, we are closing the sockets,
but that's not enough. We must also:

1) Unregister them from the event loop
2) Unref the service for each socket

The last step is needed, because each socket callback holds a
reference to the service object. Since in the first step we are
unregistering the callbacks, they no longer need the reference.

case, weird things may happen.

Also, there's a little bug I'm fixing too, upon

cb7297c150 qemuMigrationDriveMirror: Force raw format for NBD
When playing with disk migration lately, I've noticed this warning in
domain logs:

WARNING: Image format was not specified for 'nbd://masina:49153/drive-virtio-disk0' and probing guessed raw.
         Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.

So I started digging into qemu source code to see what has triggered
the warning. I'd expect qemu to know formats of guest's disks since we
tell them on command line. This lead me to qmp_drive_mirror() where
the following can be found:

    if (!has_format) {
        format = mode == NEW_IMAGE_MODE_EXISTING ? NULL : bs->drv->format_name;
    }

So, format is automatically initialized from the disk iff mode !=
"existing". Unfortunately, in migration we are tied to use this mode
(NBD doesn't support creating new images). Therefore the only way to
avoid this warning is to pass format. The discussion on the mail-list [1]
resulted in the code that always forces NBD export as "raw" format.

63aaf69bbe conf: Fix virDomainObjGetDefs when getting persistent config on a live vm
If @flags contains only VIR_DOMAIN_AFFECT_CONFIG and @vm is active, the
function would return the active config rather than the persistent one
that it should return. This happened due to the fact that
virDomainObjGetDefs was checking the updated flags which may not contain
VIR_DOMAIN_AFFECT_LIVE if it is not requested even if @vm is active.

Additionally the function would not take the flags into account when
setting the pointers which was later used to determine whether the code
needs to update the given configuration.

The mistake was caught by the virt-test suite.

beca509e43 qemu: Report all supported machine types in capabilities
Some machine types are only reported as canonical names for other
machine types, which make it a bit harder to find what machine types are
supported by a specific QEMU binary. Ideally, one would just use
/capabilities/guest/arch[@name='...']/machine/text() XPath to get a list
of all supported machine types, but it doesn't work right now.

For example, we report

    <machine canonical='pc-i440fx-2.3' maxCpus='255'>pc</machine>

in guest capabilities, but the corresponding

    <machine maxCpus='255'>pc-i440fx-2.3</machine>

is missing.

This is a result of QMP probing. With "-machine ?" parsing QEMU sends
us two lines:

pc                   Standard PC (i440FX + PIIX, 1996) (alias of pc-i440fx-2.3)
pc-i440fx-2.3        Standard PC (i440FX + PIIX, 1996) (default)

while query-machines QMP command reports both in the same entry:

{"name": "pc-i440fx-2.3", "is-default": true, "cpu-max": 255, "alias": "pc"}

Let's make sure we always report separate <machine/> for both the
canonical name and its alias and using the canonical name as the default
machine type (i.e., inserting it before its alias) in case is-default is
true.
