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).

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:
error: Unable to get domain IOThreads information
error: Unable to encode message payload

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.

We support only one IPv4 and one IPv6 default gateway.
If static IPs are not present in instance config,
then we switch on DHCP for this adapter.
PrlVmDevNet_SetAutoApply to makes necessary settings within guest OS
In linux case it creates network startup scripts
/etc/sysconfig/network-scripts/ifcfg-ethN and fills it with necessary
parameters.
There should be at least one domain for each guest
in cababilities. And in current code we don't add
domain for this guest for example.
if ((guest = virCapabilitiesAddGuest(caps, VIR_DOMAIN_OSTYPE_HVM,
VIR_ARCH_X86_64,
"vz",
NULL, 0, NULL)) == NULL)
Anyway, with two virt types it looks a litte messy, so let's
move adding guest and domain to a separate function.

Current version of SDK event dispatcing is incorrect. For most VM events (add,

doesn't have any benifints so this patch get rid of it. All dispatching is done
only on event type.

Avoid a false positive since Coverity find a path in virResizeN which
could return 0 prior to the allocation of memory and thus flags a
possible NULL dereference. Instead allocate the output buffer based
on 'nparams' and only fill it partially if need be - shouldn't be too
much a waste of space. Quicker than multiple VIR_RESIZE_N calls or
two loops of STREQ's sandwiched around a single VIR_ALLOC_N using
'n' matches from a first loop to generate the 'n' addresses to return

Commit id '81dd81e' caused a regression when attempting to print a
specific vcpuid that is out of the range of the maximum vcpus for
the guest, such as:
$ virsh vcpupin $dom 1000
VCPU: CPU Affinity
----------------------------------
$
Rather than just recover the old message, let's adjust the message based
on what would be displayed for a similar failure in the set path, such as:
$ virsh vcpupin $dom 1000
error: vcpu 1000 is out of range of persistent cpu count 2
$ virsh vcpupin $dom 1000 --live
error: vcpu 1000 is out of range of live cpu count 2

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.

Using a custom device tree image may cause unexpected behavior in
architectures that use this approach to detect platform devices. Since
usually the device tree is generated by qemu and thus it's not normally
used let's taint VMs using it to make it obvious as a possible source of
problems.
Since the balloon driver does not guarantee that it returns memory to
the host, using the value in the audit message is not a good idea.
This patch removes auditing from updating the balloon size and reports
the total physical size at startup.
