63166a4e0c Add virIndexToDiskName and fix mapping gap
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

43d0ba5f95 Clarify documentation for private symbols
The instruction "See Makefile.am" in libvirt.private_syms
always makes me think that this file is autogenerated
and should not be touched manually. This patch spares
every reader of libvirt.private_syms the hassle of
reading Makefile.am before augmenting libvirt.private_syms.

e7c78b0a94 Support QEMU's virtual FAT block device driver
Introduce a new type="dir"  mode for <disks> that allows use of
QEMU's  virtual FAT block device driver. eg

    <disk type='dir' device='floppy'>
      <source dir='/tmp/test'/>
      <target dev='fda' bus='fdc'/>
      <readonly/>
    </disk>

b827338a72 qemu-kvm needs -enable-kvm flag for VT optimization
Recent qemu releases require command option '-enable-qemu' in order
for the kvm functionality be activated. Libvirt needs to pass this flag
to qemu when starting a domain. Note that without the option,
even if both the kernel and qemu support KVM, KVM will not be activated
and VMs will be very slow.

  line option from help and add it when running kvm

f2f656d426 Removing devicePath member from dev struct
I realized that I inadvertently added a member to the def struct to
contain each device's sysfs path when there was an existing member in the
dev struct for "OS specific path to device metadat, eg sysfs"  Since the
udev backend needs to record the sysfs path while it's in the process of
creating the device, before the dev struct gets allocated, I chose to
remove the member from the dev struct.

645f4acafe esx: Fix MAC address formatting
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.

5313dc372b Fix incorrect reference counting logic in qemu monitor open
The QEMU monitor open method would not take a reference on
the virDomainObjPtr until it had successfully opened the
monitor. The cleanup code upon failure to open though would
call qemuMonitorClose() which would in turn decrement the
reference count. This caused the virDoaminObjPtr to be mistakenly
freed and then the whole driver crashes

e6cbadd588 Remove capng_lock() call when spawning LXC container init process
The capng_lock() call sets the SECURE_NO_SETUID_FIXUP and SECURE_NOROOT
bits on the process. This prevents the kernel granting capabilities to
processes with an effective UID of 0, or with setuid programs. This is
not actually what we want in the container init process. It should be
allowed to run setuid processes & keep capabilities when root. All that
is required is masking a handful of dangerous capabilities from the
bounding set.
