Create qemuBuildCommandLineValidate to make some checks before trying
to build the command. This will move some logic from much later to much
earlier - we shouldn't be adjusting any data so that shouldn't matter.

Since the code is changing the source image path by modifying the
existing XML snippet the <backingStore> stays in place.
As <backingStore> is relevant to the <source> part of the image, the
update of that part makes the element invalid.
CD/floppy images usually don't have a backing chain and the element is
currently ignored though but it might start being used in the future so
let's start behaving correctly.
Drop the <backingStore> subtree once we want to update the XML.
Before this patch, you'd get:
$ virsh change-media --eject --print-xml 10 hdc
<disk type="file" device="cdrom">
<driver name="qemu" type="qcow2"/>
<backingStore type="file" index="1">
<format type="qcow2"/>
<source file="/var/lib/libvirt/images/vm.1436949097"/>
<backingStore/>
</backingStore>
<target dev="hdc" bus="ide"/>
...
</disk>
After:
$ virsh change-media --eject --print-xml 10 hdc
<disk type="file" device="cdrom">
<driver name="qemu" type="qcow2"/>
<target dev="hdc" bus="ide"/>
...
</disk>
This was only used for test 'xml blanking', which has now all
been removed, and isn't an ideal paradigm anyways since it
inhibits easy XML regeneration.
The memory XML blanking is only there to avoid the unit= churn that
was added by default a long time ago.
Drop the blanking, switch over to using the standard comparison
helpers, and regenerate the output with VIR_TEST_REGENERATE_OUTPUT.
If a qemuargv has iscsi or ceph secrets on the command line, we will
convert that to XML like:
<auth username='myname'>
<secret type='iscsi'/>
</auth>
This is not valid XML, as either a UUID or usage must be specified in
the secret block. It's not clear though how the argv2xml code can do
anything correct here, since XML like this requires a libvirt secret
object to have already been defined.
The current test suite handles this by blanking out any <secret> block
in the XML. This avoids domainschematest failures.
Instead of blanking, let's hardcode a usage= name. This lets us test
the other bits of generated <secret> XML, and is a step towards wiring
up VIR_TEST_REGENERATE_OUTPUT
Now that the file migration doesn't require us to use 'dd' and other
legacy stuff for too old qemus we don't even have to calcuate the
offsets and other stuff.
With the currently supported qemus we always migrate to file
descriptors so the old function is not required any more.
Additionally QEMU_MONITOR_MIGRATE_TO_FILE_TRANSFER_SIZE macro is now
unused.
In cf113e8d we changed the declaration of
virCgroupAllowDevicePath() and virCgroupDenyDevicePath().
However, while updating the stub for non-cgroup platforms for the
former we forgot to update the latter too causing a build
failure.

This reverts commit 611a278fa4.
According to the original commit message, this is dead code:
It is highly unlikely that a backend will know how to create a
volume from a different volume (buildVolFrom) and not know how to
create an empty volume (createVol).
Since we introduced listing API earlier in these series, it's time
to wire up the API to the virt-admin client.
Signed-off-by: Erik Skultety <eskultet@redhat.com>
This API is merely a convenience API, i.e. when managing clients connected to
daemon's servers, we should know (convenience) which server the specific client
is connected to. This implies a client-side representation of a server along
with a basic API to let the administrating client know what servers are actually
available on the daemon.

This is the key structure of all management operations performed on the
daemon/clients. An admin client needs to be able to identify
another client (either admin or non-privileged client) to perform an
action on it. This identification includes a server the client is
connected to, thus a client-side representation of a server is needed.
Signed-off-by: Erik Skultety <eskultet@redhat.com>
This change is merely because admin_server would contain all the code
from dispatchers and helpers to the actual APIs. Admin should have
similar structure to the daemon-side remote driver - dispatchers and
helpers in a separate module, APIs in a separate module.
Best viewed with -M.

Since the daemon can manage and add (at fresh start) multiple servers,
we also should be able to add them from a JSON state file in case of a
daemon restart, so post exec restart support for multiple servers is also
provided. Patch also updates virnetdaemontest accordingly.

The method will now return 0 on success and -1 on error, rather than number of
items which it iterated over before it returned back to the caller. Since the
only place where we actually check the number of elements iterated is in
virhashtest, return value of 0 and -1 can be a pretty accurate hint that it
iterated over all the items. However, if we really want to know the number of
items iterated over (like virhashtest does), a counter has to be provided
through opaque data to each iterator call. This patch adjusts return value of
virHashForEach, refactors the body, so it returns as soon as one of the
iterators fail and adjusts virhashtest to reflect these changes.
Signed-off-by: Erik Skultety <eskultet@redhat.com>
Our existing virHashForEach method iterates through all items disregarding the
fact, that some of the iterators might have actually failed. Errors are usually
dispatched through an error element in opaque data which then causes the
original caller of virHashForEach to return -1. In that case, virHashForEach
could return as soon as one of the iterators fail. This patch changes the
iterator return type and adjusts all of its instances accordingly, so the
actual refactor of virHashForEach method can be dealt with later.

When adding disk images to ACL we may call those functions on NFS
shares. In that case we might get an EACCES, which isn't really relevant
since NFS would not hold a block device. This patch adds a flag that
allows to stop reporting an error on EACCES to avoid spaming logs.
Currently there's no functional change.
Since commit 47e5b5ae virCgroupAllowDevice allows to pass -1 as either
the minor or major device number and it automatically uses '*' in place
of that. Reuse the new approach through the code and drop the duplicated
functions.
After removing capability check for fd migration the code that was left
behind didn't make quite sense. The old exec migration would be used in
case when pipe() failed. Remove the old code and make failure of pipe()
a hard error.
This additionally removes usage of virCgroupAllowDevicePath outside of
qemu_cgroup.c.
Since no value in the virGICVersion enumeration is negative, a clever
enough compiler can report an error such as
src/conf/domain_conf.c:15337:75: error: comparison of unsigned enum
expression < 0 is always false [-Werror,-Wtautological-compare]
if ((def->gic_version = virGICVersionTypeFromString(tmp)) < 0 ||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~
virGICVersionTypeFromString() can, however, return a negative value if
the input string is not part of the enumeration, so we definitely need
that check.
Work around the problem by storing the return value in a temporary int
variable.
Create new modules qemu_domain_address.c and qemu_domain_address.h to
contain all the new functions and header data. Additionally move any
supporting static functions.
Make qemuDomainSupportsPCI non static.
Also, move and rename the following:
qemuSetSCSIControllerModel to qemuDomainSetSCSIControllerModel
qemuCollectPCIAddress to qemuDomainCollectPCIAddress
qemuValidateDevicePCISlotsPIIX3 to qemuDomainValidateDevicePCISlotsPIIX3
qemuAssignDevicePCISlots to qemuDomainAssignDevicePCISlots
