[Libguestfs] [PATCH 43 0/7] v2v: switch to ocaml-libvirt
Hi, this series switches virt-2v to ocaml-libvirt, embedding the latest version of it from git. This way, it is possible to improve the way v2v connects to libvirt for both input, and output modules, and interacts with libvirt (e.g. no more virsh calls needed in virt-v2v). As side effect, virt-v2v now requires libvirt, as keeping it optional would create too much burden. I could not test all the libvirt input modes (like VDDK, and Xen), but VMware and libvirtxml work fine as before. Changes from v3: - rebase on master - update libvirt-ocaml from its master branch - use $(srcdir) in common/mllibvirt/Makefile.am - parse_libvirt_xml: open a libvirt connection only when needed (and only once) Changes from v2: - rebase on master Changes from v1: - rebase on master - update ocaml-libvirt from libvirt-ocaml.git on libvirt.org, and adjust the code to it - pass again the URI to input_libvirt_vddk, so an error message is preserved Pino Toscano (7): v2v: require libvirt common: Bundle the libvirt-ocaml library for use by virt-v2v v2v: switch to ocaml-libvirt v2v: -o libvirt: use a Lazy for the connection v2v: -o libvirt: switch away from virsh v2v: test-harness: stop using the external ocaml-libvirt build: stop looking for ocaml-libvirt .gitignore | 2 + Makefile.am | 5 +- common/mllibvirt/Makefile.am | 102 ++ common/mllibvirt/generator.pl | 908 +++++++++++++ common/mllibvirt/libvirt.README | 9 + common/mllibvirt/libvirt.ml | 1673 ++++++++++++++++++++++++ common/mllibvirt/libvirt.mli | 1647 ++++++++++++++++++++++++ common/mllibvirt/libvirt_c_epilogue.c | 462 +++++++ common/mllibvirt/libvirt_c_oneoffs.c | 1714 +++++++++++++++++++++++++ common/mllibvirt/libvirt_c_prologue.c | 134 ++ configure.ac | 1 + docs/C_SOURCE_FILES | 1 - m4/guestfs-ocaml.m4 | 4 - po/POTFILES | 1 - v2v/Makefile.am | 26 +- v2v/copy_to_local.ml | 7 +- v2v/input_libvirt.ml | 20 +- v2v/input_libvirt_other.ml | 27 +- v2v/input_libvirt_other.mli | 5 +- v2v/input_libvirt_vcenter_https.ml | 13 +- v2v/input_libvirt_vcenter_https.mli | 2 +- v2v/input_libvirt_vddk.ml | 15 +- v2v/input_libvirt_vddk.mli | 4 +- v2v/input_libvirt_xen_ssh.ml | 13 +- v2v/input_libvirt_xen_ssh.mli | 2 +- v2v/libvirt_utils-c.c | 539 -------- v2v/libvirt_utils.ml | 95 +- v2v/libvirt_utils.mli | 51 +- v2v/output_libvirt.ml | 56 +- v2v/parse_libvirt_xml.ml | 23 +- v2v/parse_libvirt_xml.mli | 11 +- v2v/test-harness/Makefile.am | 5 +- v2v/v2v.ml | 12 +- 33 files changed, 6893 insertions(+), 696 deletions(-) create mode 100644 common/mllibvirt/Makefile.am create mode 100755 common/mllibvirt/generator.pl create mode 100644 common/mllibvirt/libvirt.README create mode 100644 common/mllibvirt/libvirt.ml create mode 100644 common/mllibvirt/libvirt.mli create mode 100644 common/mllibvirt/libvirt_c_epilogue.c create mode 100644 common/mllibvirt/libvirt_c_oneoffs.c create mode 100644 common/mllibvirt/libvirt_c_prologue.c delete mode 100644 v2v/libvirt_utils-c.c -- 2.20.1
While there are input modes that do not use libvirt, making libvirt
mandatory for virt-v2v slightly simplifies the code now, and allow for
further improvements/integration with libvirt later on.

[Libguestfs] [PATCH v4 2/7] common: Bundle the libvirt-ocaml library for use by virt-v2v
Add a copy of the libvirt-ocaml library, currently available at:
https://libvirt.org/git/?p=libvirt-ocaml.git;a=summary
This is a snapshot at commit d3ed8dcf1b0a6a8a855ceecbe0bb97f21e6665e3,
which has all the features we need (and that builds fine).
It is expected to stay synchronized with upstream, until there is a new
upstream release, and it will be widespread enough.

+
+(**
+ {2 Introduction and examples}
+
+ This is a set of bindings for writing OCaml programs to
+ manage virtual machines through {{:https://libvirt.org/}libvirt}.
+
+ {3 Using libvirt interactively}
+
+ Using the interactive toplevel:
+
+{v
+$ ocaml -I +libvirt
+ Objective Caml version 3.10.0
+
+# #load "unix.cma";;
+# #load "mllibvirt.cma";;
+# let name = "test:///default";;
+val name : string = "test:///default"
+# let conn = Libvirt.Connect.connect_readonly ~name () ;;
+val conn : Libvirt.ro Libvirt.Connect.t = <abstr>
+# Libvirt.Connect.get_node_info conn;;
+ : Libvirt.Connect.node_info +{Libvirt.Connect.model = "i686";
Libvirt.Connect.memory = 3145728L;
+ Libvirt.Connect.cpus = 16; Libvirt.Connect.mhz = 1400;
+ Libvirt.Connect.nodes = 2; Libvirt.Connect.sockets = 2;
+ Libvirt.Connect.cores = 2; Libvirt.Connect.threads = 2}
+v}
+
+ {3 Compiling libvirt programs}
+
+ This command compiles a program to native code:
+
+{v
+ocamlopt -I +libvirt mllibvirt.cmxa list_domains.ml -o list_domains
+v}
+
+ {3 Example: Connect to the hypervisor}
+
+ The main modules are {!Libvirt.Connect}, {!Libvirt.Domain} and
+ {!Libvirt.Network} corresponding respectively to the
+ {{:https://libvirt.org/html/libvirt-libvirt-host.html}virConnect*},
+ {{:https://libvirt.org/html/libvirt-libvirt-domain.html}virDomain*}, and
+ {{:https://libvirt.org/html/libvirt-libvirt-network.html}virNetwork*}
+ functions from libvirt.
+ For brevity I usually rename these modules like this:
+
+{[
+module C = Libvirt.Connect
+module D = Libvirt.Domain
+module N = Libvirt.Network
+]}
+
+ To get a connection handle, assuming a Xen hypervisor:
+
+{[
+let name = "xen:///"
+let conn = C.connect_readonly ~name ()
+]}
+
+ {3 Example: List running domains}
+
+{[
+open Printf
+
+let domains = D.get_domains conn [D.ListActive] in
+List.iter (
+ fun dom ->
+ printf "%8d %s\n%!" (D.get_id dom) (D.get_name dom)
+) domains;
+]}
+
+ {3 Example: List inactive domains}
+
+{[
+let domains = D.get_domains conn [D.ListInactive] in
+List.iter (
+ fun dom ->
+ printf "inactive %s\n%!" (D.get_name dom)
+) domains;
+]}
+
+ {3 Example: Print node info}
+
+{[
+let node_info = C.get_node_info conn in
+printf "model = %s\n" node_info.C.model;
+printf "memory = %Ld K\n" node_info.C.memory;
+printf "cpus = %d\n" node_info.C.cpus;
+printf "mhz = %d\n" node_info.C.mhz;
+printf "nodes = %d\n" node_info.C.nodes;
+printf "sockets = %d\n" node_info.C.sockets;
+printf "cores = %d\n" node_info.C.cores;
+printf "threads = %d\n%!" node_info.C.threads;
+
+let hostname = C.get_hostname conn in
+printf "hostname = %s\n%!" hostname;
+
+let uri = C.get_uri conn in
+printf "uri = %s\n%!" uri
+]}

+ objects should be completely safe. If you find any safety issues
+ or if your pure OCaml program ever segfaults, please contact the author.
+
+ You can force a libvirt object to be freed early by calling
+ the {!Libvirt.Connect.close} function on the object. This shouldn't
+ affect the safety of garbage collection and should only be used when
+ you want to explicitly free memory. Note that explicitly
+ closing a connection object does nothing if there are still
+ unclosed domain or network objects referencing it.
+
+ Note that even though you hold open (eg) a domain object, that
+ doesn't mean that the domain (virtual machine) actually exists.
+ The domain could have been shut down or deleted by another user.
+ Thus domain objects can raise odd exceptions at any time.
+ This is just the nature of virtualisation.
+
+ {3 Backwards and forwards compatibility}
+
+ OCaml-libvirt requires libvirt version 1.2.8 or later. Future
+ releases of OCaml-libvirt will use newer features of libvirt
+ and therefore will require later versions of libvirt. It is always
+ possible to dynamically link your application against a newer
+ libvirt than OCaml-libvirt was originally compiled against.
+
+ {3 Get list of domains and domain infos}
+
+ This is a very common operation, and libvirt supports various
+ different methods to do it. We have hidden the complexity in a
+ flexible {!Libvirt.Domain.get_domains} and
+ {!Libvirt.Domain.get_domains_and_infos} calls which is easy to use and
+ automatically chooses the most efficient method depending on the
+ version of libvirt in use.
+
+ {3 Threads}
+
+ You can issue multiple concurrent libvirt requests in
+ different threads. However you must follow this rule:
+ Each thread must have its own separate libvirt connection, {i or}
+ you must implement your own mutex scheme to ensure that no
+ two threads can ever make concurrent calls using the same
+ libvirt connection.
+
+ (Note that multithreaded code is not well tested. If you find
+ bugs please report them.)
+
+ {3 Initialisation}
+
+ Libvirt requires all callers to call virInitialize before
+ using the library. This is done automatically for you by
+ these bindings when the program starts up, and we believe
+ that the way this is done is safe.

+ *------------------------------------------------------------------
+ *
+ * Libvirt does some tricky reference counting to keep track of
+ * virConnectPtr's, virDomainPtr's and virNetworkPtr's.
+ *
+ * There is only one function which can return a virConnectPtr
+ * (virConnectOpen*) and that allocates a new one each time.
+ *
+ * virDomainPtr/virNetworkPtr's on the other hand can be returned
+ * repeatedly (for the same underlying domain/network), and we must
+ * keep track of each one and explicitly free it with virDomainFree
+ * or virNetworkFree. If we lose track of one then the reference
+ * counting in libvirt will keep it open. We therefore wrap these
+ * in a custom block with a finalizer function.
+ *
+ * We also have to allow the user to explicitly free them, in
+ * which case we set the pointer inside the custom block to NULL.
+ * The finalizer notices this and doesn't free the object.
+ *
+ * Domains and networks "belong to" a connection. We have to avoid
+ * the situation like this:
+ *
+ * let conn = Connect.open ... in
+ * let dom = Domain.lookup_by_id conn 0 in
+ * (* conn goes out of scope and is garbage collected *)
+ * printf "dom name = %s\n" (Domain.get_name dom)
+ *
+ * The reason is that when conn is garbage collected, virConnectClose
+ * is called and any subsequent operations on dom will fail (in fact
+ * will probably segfault). To stop this from happening, the OCaml
+ * wrappers store domains (and networks) as explicit (dom, conn)
+ * pairs.
+ *
+ * Update 2008/01: Storage pools and volumes work the same way as
+ * domains and networks.

[Libguestfs] [PATCH v4 3/7] v2v: switch to ocaml-libvirt
Currently virt-v2v has few custom C-based functions for libvirt
operations, which are limited in what they do, and there is a lot of
duplicated code.
Instead, switch to ocaml-libvirt for all the libvirt interaction
currently done by the Libvirt_utils module. This has few advantages:
- each input & output module now opens a libvirt connection only once,
only when needed
- no need to pass URIs and passwords around, if not needed
- a wider range of libvirt APIs can now be used, with no need to create
bindings manually
The hierarchy of input_libvirt* classes is changed to take a Lazy object
with the libvirt connection, accessing it through a "proctected"
method:
this way, the connection is opened only at the first access.
Also, the Libvirt_utils module now is just helpers around the Libvirt
module, to centralize error handling, and few common operations.

Now that we have a proper libvirt connection object, use it directly to
refresh the storage pool, and define the final guest. This avoids
spawning a new virsh process twice, with no possibility to even share a
possible authentication required.

Re: [Libguestfs] [PATCH v4 2/7] common: Bundle the libvirt-ocaml library for use by virt-v2v
So for patches 2, 6 and 7 ... I think for 2, we really need a plan, written down, about how and when we're going to remove the bundled library. It might be included as a README in the common/mllibvirt/ directory. But it needs to be clear about when it goes and how we're going to work towards that. For patch 6, I really need to either get rid of the test harness or move it out somewhere, but your change is fine. Patch 7 is fine, but depends on patch 2.
