The s390(x) architecture doesn't feature a PCI bus. For the purpose of
supporting virtio devices a virtual bus called virtio-s390 is used.
A new address type VIR_DOMAIN_DEVICE_ADDRESS_TYPE_VIRTIO_S390 is used to
distinguish the virtio devices on s390 from PCI-based virtio devices.

Rewrote the device assignment parts in tests to use qemuDomainAssignAddresses.
This way the tests will work for new device address types as they show

This is in preparation of the enablement of s390 guests with virtio devices.

The assignment of device addresses happens in different places, i.e. the
qemu driver and process modules as well as in the unit tests in slightly
different flavors. Currently, these are PPC spapr-vio and PCI
devices, virtio-s390 (not PCI based) will follow.

By optionally passing to qemuDomainAssignAddresses the domain
object and the capabilities it is now possible to call the function
from most of the places (except for hotplug) where address assignment
is done.

This makes the driver fail with a clear error message in case of UUID
collisions (for example if somebody copied a container configuration
without updating the UUID) and also raises an error on other hash map
failures.

OpenVZ itself doesn't complain about duplicate UUIDs since this
parameter is only used by libvirt.

Commit 5e6ce1 moved down detection of the ACPI feature in
qemuParseCommandLine. However, when ACPI is detected, it clears
all feature flags in def->features to only set ACPI. This used to
be fine because this was the first place were def->features was set,
but after the move this is no longer necessarily true because this
block comes before the ACPI check:

if (strstr(def->emulator, "kvm")) {
    def->virtType = VIR_DOMAIN_VIRT_KVM;
    def->features |= (1 << VIR_DOMAIN_FEATURE_PAE);
}

Since def is allocated in qemuParseCommandLine using VIR_ALLOC, we
can always use |= when modifying def->features

The only useful translation of "%s" as a format string is "%s" (I
suppose you could claim "%1$s" is also valid, but why bother).  So
it is not worth translating; fixing this exposes some instances
where we were failing to translate real error messages.  This makes
the fix of commit 097da1ab more generic, as well as ensuring no
future regressions.

Domains configured with autostart may fail to start if the host
network stack has not been started.  E.g. when using bridged
networking autostarting a domain can fail with

All the callers of virDirCreate are updated incidentally.

Instead of changing the existed virFileMakePath to accept mode
argument and modifying a pile of its uses, this patch introduces
virFileMakePathWithMode, and use it instead of mkdir() to create
the readline history dir.

Commit 122fa379 introduces option to
store more than one host entry in a storage pool source definition. That
commit causes a regression, where a check is added that only one host
entry should be present (that actualy is not present as the source
structure was just allocated and zeroed) instead of allocating memory
for the host entry.

As the storage pool sources are stored in a list of structs, the pointer
returned by virStoragePoolSourceListNewSource() shouldn't be freed as it
points in the middle of a memory block. This combined with a regression
that takes the error path every time on caused a double-free abort on
the src struct in question.

Previous commits added code to unmount the existing /proc,
/sys and /dev hierarchies on the root filesystem of the
container. This should only have been done if the container's
root filesystem was the same as the host's root. ie if
the root source is '/'.   As it is, this causes LXC containersr
to fail to start if their root source is not '/'

Recently the Ceph project defaulted auth_supported from 'none' to 'cephx'.

When no auth information was set for Ceph disks this would lead to librados defaulting to
