Introduces several new public API options for migration
- VIR_MIGRATE_PEER2PEER: With this flag the client only
invokes the virDomainMigratePerform method, expecting
the source host driver to do whatever is required to
complete the entire migration process.
- VIR_MIGRATE_TUNNELLED: With this flag the actual data
for migration will be tunnelled over the libvirtd RPC
channel. This requires that VIR_MIGRATE_PEER2PEER is
also set.
- virDomainMigrateToURI: This is variant of the existing
virDomainMigrate method which does not require any
virConnectPtr for the destination host. Given suitable
driver support, this allows for all the same modes as
virDomainMigrate()
The URI for VIR_MIGRATE_PEER2PEER must be a valid libvirt
URI. For non-p2p migration a hypervisor specific migration
URI is used.
virDomainMigrateToURI without a PEER2PEER flag is only
support for Xen currently, and it involves XenD talking
directly to XenD, no libvirtd involved at all.
* include/libvirt/libvirt.h.in: Add VIR_MIGRATE_PEER2PEER
flag for migration
* src/libvirt_internal.h: Add feature flags for peer to
peer migration (VIR_FEATURE_MIGRATE_P2P) and direct
migration (VIR_MIGRATE_PEER2PEER mode)
* src/libvirt.c: Implement support for VIR_MIGRATE_PEER2PEER
and virDomainMigrateToURI APIs.
* src/xen/xen_driver.c: Advertise support for DIRECT migration
* src/xen/xend_internal.c: Add TODO item for p2p migration
* src/libvirt_public.syms: Export virDomainMigrateToURI
method
* src/qemu/qemu_driver.c: Add support for PEER2PEER and
migration, and adapt TUNNELLED migration.
* tools/virsh.c: Add --p2p and --direct args and use the
new virDomainMigrateToURI method where possible.
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.

* cfg.mk: use $(srcdir)/ prefix for Makefile.nonreentrant include
* examples/domain-events/events-c/Makefile.am tools/Makefile.am
examples/hellolibvirt/Makefile.am: extend the include paths to
use $(top_srcdir)/include too.
* tools/virsh.c: it was possible to get vshDeinit to call itself back
via vshError, remove the doexit parameter of vshError to avoid the
possibility and make sure to exit directly after in those case.
* docs/pki_check.sh: Move to tool/virt-pki-validate.in and add
in POD man page documentation
* tools/.gitignore: Ignore generated virt-pki-validate file
* tools/Makefile.am: Install & build virt-pki-validate and
virt-pki-validate.1
* docs/remote.html, docs/remote.html.in: Refer to new tool
name virt-pki-validate
* libvirt.spec.in, mingw32-libvirt.spec.in: Add virt-pki-validate
and virt-pki-validate.1 to files list
Move the virsh tool and its man page into the tools directory
* Makefile.am: Remove rules for virsh.1 man page
* virsh.1: Remove auto-generated file
* docs/Makefile.am: Remove rules for virsh.pod man page
* docs/virsh.pod: Move to tools/ directory
* src/Makefile.am, src/.gitignore: Remove rules for virsh
* src/console.c, src/console.h, src/*.ico, src/virsh_win_icon.rc,
src/virsh.c: Move into tools/ directory
* tools/Makefile.am: Add rules for building virsh
* tools/.gitignore: Ignore virsh built files

virsh location
