by Atsushi SAKAI
Hello, Dan Smith
May I commit this patch for MinGW compilation?
veth.c is not necessary for MinGW.
Thanks

[Libvir] [PATCH] Add bus attribute to disk target definition
by Soren Hansen
Hi!
I'd like to propose that the following patch gets applied against
libvirt. It adds the option of putting a bus attribute on a disk target.
To acommodate this, it also changes the way drives are defined for kvm
from the old "-hda /path/to/file -boot c" style to the new "-drive
file=/path/to/file,if=ide,boot=on". This makes it possible to specify
virtio, scsi, and ide disks.

[libvirt] [PATCH] Return VIR_ERR_NO_SUPPORT in qemu SetMemory()/SetVcpus() if domain is active.
by Kaitlin Rupert
qemu doesn't support setting the memory or vcpus of an active guest. In
this case, use the VIR_ERR_NO_SUPPORT return code to indicate that the
action failed because its not supported.

[libvirt] PATCH: Generic internal API for network XML parser/formatter
by Daniel P. Berrange
We currently have two drivers which handle the networking XML containing
duplicated parsers and formatters for the XML, and very similar structs.
This patch introduces a new general purpose internal API for parsing and
formatting network XML, and representing it as a series of structs.
This code is derived from the current equivalent code in the QEMU driver
for networks.
The naming conventions I'm adopting in this patch follow those in the
storage driver:
- virNetworkPtr - the public opaque object in libvirt.h
- virNetworkObjPtr - the primary internal object for network state
- virNetworkDefPtr - the configuration data for a network
A virNetworkObjPtr contains a reference to one or two virNetworkDefPtr
objects - the current live config, and potentially a secondary inactive
config which will become live at the next restart.
The structs are defined in network_conf.h, along with a bunch of APIs for
dealing with them. These APIs are the same as similarly named ones from
the current qemu driver, but I'll go over them again for a reminder:
virNetworkObjPtr virNetworkFindByUUID(const virNetworkObjPtr nets,
const unsigned char *uuid);
virNetworkObjPtr virNetworkFindByName(const virNetworkObjPtr nets,
const char *name);
Allow lookup of a virNetworkObjPtr object based on its name or UUID, as
typically obtained from the public virNetworkPtr object.
The 'nets' parameter to both of thse is a linked list of networks which
are currently known to the driver using this API.
void virNetworkDefFree(virNetworkDefPtr def);
void virNetworkObjFree(virNetworkObjPtr net);
Convenience APIs to totally free the memory associated with these
objects.
virNetworkObjPtr virNetworkAssignDef(virConnectPtr conn,
virNetworkObjPtr *nets,
const virNetworkDefPtr def);
Given a virNetworkDefPtr object, it'll search for a pre-existing
virNetworkObjPtr object with matching config. If one is found, its
config will be updated, otherwise a new object will be allocated.
void virNetworkRemoveInactive(virNetworkObjPtr *nets,
const virNetworkObjPtr net);
Convenience for removing and free'ing a virNetworkObjPtr object in
the current list of active networks.
virNetworkDefPtr virNetworkDefParse(virConnectPtr conn,
const char *xmlStr,
const char *displayName);
Given an XML document describing a network, parses the doc and generates
a virNetworkDefPtr to represent it in memory.
char *virNetworkDefFormat(virConnectPtr conn,
const virNetworkDefPtr def);
Given a virNetworkDefPtr object, generate a XML document describing the
network.
As a mentioned earlier, the impl of these APIs is just copied from the QEMU
driver, but instead of using pre-declared char[PATH_MAX] fields, we allocate
memory for strings as required.
Regards,
Daniel

[libvirt] libvirt-java patch
by Tóth István
This patch contains:
-random bugfixes
-gcc -Wall "fixes"
-a few new constants for 4.x
-Implementation of virConnectAuth
-javah build fixes (One .class file can generate many .h files.)
It is NOT a full update for 4.x, the only major new feature is
authentication support.
I've attached the patch, and the new files. (Is there some way to
generate patches with new files?)
Please remove the
/src/jni/org_libvirt_VirDomain_CreateFlags.h
/src/jni/org_libvirt_VirDomain_MigrateFlags.h
files from the CVS, as these are auto-generated.
regards
István

[libvirt] HTTP-API for libvirt
by Stefan de Konink
New thread.
> Honnestly I'm still lost trying to understand what you wanted to do.
I have implemented a webserver plugin that allows (by mDNS) to access
all 'VMs' on the network.
http://xen.bot.nu/virt/ <- demo
> I didn't understand the point, I just noted you wanted to put things
> in libvirtd, something about event API while to me i don't see the even side
> of the proposal.
Using mDNS, mDNS events can be used on the network to subscribe to
certain VM changes. Reboot/Shutdown/etc.
> Now suggesting to convey this as part of Java *bindings* sounds even more
> confusing, how does that relate at all ?
You proposed (new) bindings for Java. I have written new bindings using
the HTTP protocol. I wonder what should be done to get it adapted into
libvirt, or standardize the format (like any other API).

[libvirt] LXC veth.c issue
by Atsushi SAKAI
Hello, Dan Smith
Please check your moveInterfaceToNetNs on veth.c
**rc** and **len** have warning problem.
http://builder.virt-manager.org/logs/modules/libvirt--devel-build-output.log
P.S.
Many Dan stay in this mailing list.
Also My previous patch save this problem for general users
but not for LXC users :-)
Thanks
