Replace free(virBufferContentAndReset()) with virBufferFreeAndReset().
Update documentation and replace all remaining calls to free() with
calls to VIR_FREE(). Also add missing calls to virBufferFreeAndReset()
and virReportOOMError() in OOM error cases.
esxVMX_IndexToDiskName handles indices up to 701. This limit comes
from a mapping gap in virDiskNameToIndex:
sdzy -> 700
sdzz -> 701
sdaaa -> 728
sdaab -> 729
This line in virDiskNameToIndex causes this gap:
idx = (idx + i) * 26;
Fixing it by altering this line to:
idx = (idx + (i < 1 ? 0 : 1)) * 26;
Also add a new version of virIndexToDiskName that handles the inverse
mapping for arbitrary indices.
* src/esx/esx_vmx.[ch]: remove esxVMX_IndexToDiskName
* src/util/util.[ch]: add virIndexToDiskName and fix mapping gap
* tests/esxutilstest.c: update test to verify that the gap is fixed
VMware uses two MAC address prefixes: 00:0c:29 and 00:50:56. The 00:0c:29
prefix is used for ESX server generated addresses. The 00:50:56 prefix is
split into two parts. MAC addresses above 00:50:56:3f:ff:ff are generated
by a vCenter. The rest of the 00:50:56 prefix can be assigned manually.
Any MAC address within the 00:0c:29 and 00:50:56 prefix can be specified
in a domain XML config and the driver will handle the details internally.

There is currently no way to determine the libvirt version of a remote
libvirtd we are connected to. This is a useful piece of data to enable
feature detection.
Introduce a number of new APIs to expose some boolean properties
of objects, which cannot otherwise reliably determined, nor are
aspects of the XML configuration.
* virDomainIsActive: Checking virDomainGetID is not reliable
since it is not possible to distinguish between error condition
and inactive domain for ID of -1.
* virDomainIsPersistent: Check whether a persistent config exists
for the domain
* virNetworkIsActive: Check whether the network is active
* virNetworkIsPersistent: Check whether a persistent config exists
for the network
* virStoragePoolIsActive: Check whether the storage pool is active
* virStoragePoolIsPersistent: Check whether a persistent config exists
for the storage pool
* virInterfaceIsActive: Check whether the host interface is active
* virConnectIsSecure: whether the communication channel to the
hypervisor is secure
* virConnectIsEncrypted: whether any network based commnunication
channels are encrypted
NB, a channel can be secure, even if not encrypted, eg if it does
not involve the network, like a UNIX socket, or pipe.

A character device's target (it's interface in the guest) had only a
single property: port. This patch is in preparation for adding targets
which require other properties.
Since this changes the conf type for character devices this affects
a number of drivers:
* src/conf/domain_conf.[ch] src/esx/esx_vmx.c src/qemu/qemu_conf.c
src/qemu/qemu_driver.c src/uml/uml_conf.c src/uml/uml_driver.c
src/vbox/vbox_tmpl.c src/xen/xend_internal.c src/xen/xm_internal.c:
target properties are moved into a union in virDomainChrDef, and a
targetType field is added to identify which union member should be
used. All current code which touches a virDomainChrDef is updated both
to use the new union field, and to populate targetType if necessary.
If an error occurs between the allocation of an item and appending it
to the list, the item leaks. Free such orphaned items in error cases.
* src/esx/esx_vi.c: free orphaned items in error cases
The default transport for the VI API is HTTPS. If the server redirects
from HTTPS to HTTP the driver would silently follow that redirection.
The user assumes to communicate with the server over a secure transport
but isn't.
This patch disables automatical redirection following. The driver reports
an error if the server tries to redirect.
* src/esx/esx_vi.c: refactor the call to curl_easy_perform() into a
function and do error handling there, disable automatical redirection
following for curl
* src/esx/esx_vi.h: change the type of responseCode to int
Unified function naming scheme:
- 'lookup' functions query the ESX or vCenter for information
- 'get' functions return information from a local object
* src/esx/esx_driver.c, src/esx/esx_vi.[ch]: unify function naming
In order to register a new virtual machine the ESX driver needs to upload
a VMX file to a datastore. Try to put this file beside the main VMDK file
of the virtual machine. Change the disk selection for datastore detection
to choose the first file-based harddisk instead of just the first disk.
The first disk may be a CDROM disk and ISO images are normaly not located
in the virtual machine's directory.
* src/esx/esx_driver.c: change disk selection for datastore detection
This allows to use domain-xml-from-native with VMX files that reference
unavailable datastores.
* src/esx/esx_vmx.c: fallback to the preliminary name if the datastore
cannot be found
Implementation of tunnelled migration, using a Unix Domain Socket
on the qemu backend. Note that this requires very new versions of
qemu (0.10.7 at least) in order to get the appropriate bugfixes.

Add the virStrncpy function, which takes a dst string, source string,
the number of bytes to copy and the number of bytes available in the
dest string. If the source string is too large to fit into the
destination string, including the \0 byte, then no data is copied and
the function returns NULL. Otherwise, this function copies n bytes
from source into dst, including the \0, and returns a pointer to the
dst string. This function is intended to replace all unsafe uses
of strncpy in the code base, since strncpy does *not* guarantee that
the buffer terminates with a \0.

While trying to remove uses of unsafe strncpy in the tree, I came
across a couple of usages in the ESX driver. To my eyes, the snprintf
replacements do the same thing in less code, and are also safer.
