244ebb8f2b Do not try to release virtio serial addresses
Return 0 instead of 1, so that qemuDomainAttachChrDevice does not
assume the address neeeds to be released on error.

No functional change, since qemuDomainReleaseDeviceAddress has been a noop
for virtio serial addresses since the address cache was removed
in commit 19a148b.

ac518960a6 Introduce virDomainVirtioSerialAddrAutoAssign again
This time do not require an address cache as a parameter.

0512dd26ee Add 'FromCache' to virDomainVirtioSerialAddrAutoAssign
Commit 19a148b dropped the cache from QEMU's private domain object.
Assume the callers do not have the cache by default and use
a longer name for the internal ones that do.

This makes the shorter 'virDomainVirtioSerialAddrAutoAssign'
name availabe for a function that will not require the cache.

debf2f0b8a wireshark: Strip prefix correctly
Even when we're building $plugindir ourselves because we can't
retrieve it using pkg-config, we still want to strip the prefix,

0701abcb3b qemu: Add support for using AES secret for SCSI hotplug
Support for virtio disks was added in commit id 'fceeeda', but not for
SCSI drives. Add the secret for the server when hotplugging a SCSI drive.
No need to make any adjustments for unplug since that's handled during
the qemuDomainDetachDiskDevice call to qemuDomainRemoveDiskDevice in
the qemuDomainDetachDeviceDiskLive switch.

Added a test to/for the command line processing to show the command line
options when adding a SCSI drive for the guest.

8550e8585e qemu: Add secret object hotplug for TCP chardev TLS
https://bugzilla.redhat.com/show_bug.cgi?id=1300776

Complete the implementation of support for TLS encryption on
chardev TCP transports by adding the hotplug ability of a secret
to generate the passwordid for the TLS object for chrdev, RNG,
and redirdev.

Fix up the order of object removal on failure to be the inverse
of the attempted attach (for redirdev, chr, rng) - for each the
tls object was being removed before the chardev backend.

Likewise, add the ability to hot unplug that secret object as well
and be sure the order of unplug matches that inverse order of plug.

daf5c651f0 qemu: Add a secret object to/for a char source dev
Add the secret object so the 'passwordid=' can be added if the command line
if there's a secret defined in/on the host for TCP chardev TLS objects.

Preparation for the secret involves adding the secinfo to the char source
device prior to command line processing. There are multiple possibilities
for TCP chardev source backend usage.

Add test for at least a serial chardev as an example.

f830674bf3 libxl: fix leaking of allocated migration ports
Although the migration port is immediately released in the
finish phase of migration, it was never set in the domain
private object when allocated in the prepare phase. So
libxlDomainMigrationFinish() always released a 0-initialized
migrationPort, leaking any allocated port. After enough
migrations to exhaust the migration port pool, migration would
fail with

error: internal error: Unable to find an unused port in range
       'migration' (49152-49216)

Fix it by setting libxlDomainObjPrivate->migrationPort to the
port allocated in the prepare phase. While at it, also fix
leaking an allocated port if the prepare phase fails.

ab9202e431 qemu: replace calls to virDomainPCIAddressReserveNext*() with static function
An upcoming commit will remove the "flag" argument from all the calls
to reserve the next available address|slot, but I don't want to change
the arguments in the hypervisor-agnostic
virDomainPCIAddressReserveNext*() functions, so this patch places a
simple qemu-specific wrapper around those functions - the new
functions don't take a flags arg, but grab it from the device's
info->pciConnectFlags.

848e7ff2b3 conf: new function virDomainPCIAddressReserveNextAddr()
There is an existing virDomainPCIAddressReserveNextSlot() which will
reserve all functions of the next available PCI slot. One place in the
qemu PCI address assignment code requires reserving a *single*
function of the next available PCI slot. This patch modifies and
renames virDomainPCIAddressReserveNextSlot() so that it can fulfill
both the original purpose and the need to reserve a single function.

(This is being done so that the abovementioned code in qemu can have
its "kind of open coded" solution replaced with a call to this new
function).

7c8df1e82f domain: fix migration to older libvirt
Since TLS was introduced hostwide for libvirt 2.3.0 and a domain
configurable haveTLS was implemented for libvirt 2.4.0, we have to
modify the migratable XML for specific case where the 'tls' attribute
is based on setting from qemu.conf.

The "tlsFromConfig" is libvirt internal attribute and is stored only in
status XML to ensure that when libvirtd is restarted this internal flag
is not lost by the restart.

That flag is used to decide whether we should put *tls* attribute to
migratable XML or not.
