When wiping a volume we just rewrite all the data of the volume, not
only the content.  Since format gets overridden, we need to recreate the
volume.  However we can't do that for every possible format out there.
Since it was only coded for the ploop volume type, let's document what
might be the consequences instead of forbidding it for every other
format out there.

  This patch reflects cases when <interface> element and its <source>
subelement for network type are formated based on actual type resolved
from referenced network instead of original one. networkAllocateActualDevice
and virDomainActualNetDefContentsFormat are taken as reference.

Ever since virDomainCreateWithFlags() was introduced by de3aadaa
[drivers: add virDomainCreateWithFlags if virDomainCreate exists], the
domain ID retrieved with virDomainGetID() was incorrect for several
drivers after virDomainCreateWithFlags() was called. The API consumer
had to look up the domain anew to retrieve the correct ID.

For the ESX driver, this was fixed in 6139b274 [esx: Update ID after
starting a domain]. For the openvz driver, it was fixed in fd81a097
[openvzDomainCreateWithFlags: set domain id to the correct value]. The
test driver, the OpenNebula driver (removed in the meantime) and the
vbox driver were already updating the domain ID correctly in
domainCreate().

Copy over the ID in qemuDomainCreateWithFlags() to fix this for the qemu
driver, too.

The original name 'admin_uri_default' was introduced to our code by commit
dbecb87f. However, at that time we already had a separate config file for
admin library but the commit mentioned above didn't properly adjust the
config's option name. The result is that when we're loading the config, we
check a non-existent config option (there's not much to do with the URIs
anyway, since we only allow local connection). Additionally, virt-admin's man
page documents, that the default URI can be altered by setting
admin_uri_default option. So the fix proposed by this patch leaves the
libvirt-admin.conf as is and adjusts the naming in the code as well as in the
virt-admin's man page.

The virJSONValueObjectCreate only consumes the object on success, so on
failure we must free - from commit id 'f4441017' (found by Coverity).

https://bugzilla.redhat.com/show_bug.cgi?id=1356436

Commit id '56057900' altered the discovery of iSCSI node targets by
using the "--op nonpersistent". This caused issues for clean environments
or if by chance a "-m node -o delete" was executed.

Since each iSCSI Storage Pool has the required iSCSI target path, use
that and the virISCSINodeNew API in order to generate the iSCSI node record.

https://bugzilla.redhat.com/show_bug.cgi?id=1356436

According to RFC 3721 (https://www.ietf.org/rfc/rfc3721.txt), there are
two ways to "discover" targets in/for the iSCSI environment. Discovery
is the process which allows the initiator to find the targets to which
it has access and at least one address at which each target may be
accessed.

The method currently implemented in libvirt using the virISCSIScanTargets
API is known as "SendTargets" discovery. This method is more useful when
the target IP Address and TCP port information are available, e.g. in
libvirt terms the "portal". It returns a list of targets for the portal.
From that list, the target can be found. This operation can also fill an
iSCSI node table into which iSCSI logins may occur. Commit id '56057900'
altered that filling by adding the "--op nonpersistent" since it was
not necessarily desired to perform that for non libvirt related targets.

The second method is "Static Configuration". This method not only needs
the IP Address and TCP port (e.g. portal), but also the iSCSI target name.
In libvirt terms this would be the device path field from the iSCSI pool
<source> XML. This patch implements the second methodology using that
required device path as the targetname.

Since commit 834c5720 which extracted the generic functionality out of virsh
and made it available for other clients like virt-admin to make use of it, it
also introduced a bug when it renamed the original VIRSH_ environment variables
to VSH_ variables. Virt-admin of course suffers from the same bug, so this
patch modifies the generic module vsh.c to construct the correct name for
environment variables of each client from information it has.

Well, the reason behind this change is that if the function is extended in some
way that e.g. would involve allocation we do not have a way of telling it to
the caller. More specifically, vshInitDebug only relies on some hardcoded
environment variables (by a mistake) that aren't documented anywhere so neither
virsh's nor virt-admin's documented environment variables take effect. One
possible solution would be duplicate the code for each CLI client or leave the
method be generic and provide means that it could figure out, which client
called it, thus initializing the proper environment variables but that could
involve operations that might as well fail in certain circumstances and the
caller should know that an error occurred.

The current LUKS support has a "luks" volume type which has
a "luks" encryption format.

This partially makes sense if you consider the QEMU shorthand
syntax only requires you to specify a format=luks, and it'll
automagically uses "raw" as the next level driver. QEMU will
however let you override the "raw" with any other driver it
supports (vmdk, qcow, rbd, iscsi, etc, etc)

IOW the intention though is that the "luks" encryption format
is applied to all disk formats (whether raw, qcow2, rbd, gluster
or whatever). As such it doesn't make much sense for libvirt
to say the volume type is "luks" - we should be saying that it
is a "raw" file, but with "luks" encryption applied.

IOW, when creating a storage volume we should use this XML

  <volume>
    <name>demo.raw</name>
    <capacity>5368709120</capacity>
    <target>
      <format type='raw'/>
      <encryption format='luks'>
        <secret type='passphrase' uuid='0a81f5b2-8403-7b23-c8d6-21ccd2f80d6f'/>
      </encryption>
    </target>
  </volume>

and when configuring a guest disk we should use

  <disk type='file' device='disk'>
    <driver name='qemu' type='raw'/>
    <source file='/home/berrange/VirtualMachines/demo.raw'/>
    <target dev='sda' bus='scsi'/>
    <encryption format='luks'>
      <secret type='passphrase' uuid='0a81f5b2-8403-7b23-c8d6-21ccd2f80d6f'/>
    </encryption>
  </disk>

This commit thus removes the "luks" storage volume type added
in

    util: Add 'luks' to the FileTypeInfo

The storage file probing code is modified so that it can probe
the actual encryption formats explicitly, rather than merely
probing existance of encryption and letting the storage driver
guess the format.

The rest of the code is then adapted to deal with
VIR_STORAGE_FILE_RAW w/ VIR_STORAGE_ENCRYPTION_FORMAT_LUKS
instead of just VIR_STORAGE_FILE_LUKS.

The commit mentioned above was included in libvirt v2.0.0.
So when querying volume XML this will be a change in behaviour
vs the 2.0.0 release - it'll report 'raw' instead of 'luks'
for the volume format, but still report 'luks' for encryption
format.  I think this change is OK because the storage driver
did not include any support for creating volumes, nor starting
guets with luks volumes in v2.0.0 - that only since then.
Clearly if we change this we must do it before v2.1.0 though.

So, when building wireshark plugin, we get the plugindir variable
from the wireshark.pc as well as prefix. Then we replace the

building to:

  plugindir="${prefix}${plugindir#ws_prefix}"

However, as you can see, there's '$' missing in front of the
ws_prefix variable. This results in the mangled plugindir, for
instance like this:
