[libvirt] libvirt [PATCHv2 2/2] Add iSCSI backend storage driver for ESX.
by Ata E Husain Bohra
The patch adds the backend driver to support iSCSI format storage pools
and volumes for ESX host. The mapping of ESX iSCSI specifics to Libvirt
is as follows:
1. ESX static iSCSI target <------> Libvirt Storage Pools
2. ESX iSCSI LUNs <------> Libvirt Storage Volumes.
The above understanding is based on http://libvirt.org/storage.html.
The operation supported on iSCSI pools includes:
1. List storage pools & volumes.
2. Get xml descriptor operaion on pools & volumes.
3. Lookup operation on pools & volumes by name, uuid and path (if applicable).
iSCSI pools does not support operations such as: Create / remove pools
and volumes.

[libvirt] [PATCH] conf: fix virDomainNetGetActualDirect*() and BridgeName()
by Laine Stump
This resolves:
https://bugzilla.redhat.com/show_bug.cgi?id=881480
These three functions:
virDomainNetGetActualBridgeName
virDomainNetGetActualDirectDev
virDomainNetGetActualDirectMode
return attributes that are in a union whose contents are interpreted
differently depending on the actual->type and so they should only
return non-0 when actual->type is 'bridge' (in the first case) or
'direct' (in the other two cases, but I had neglected to do that, so
...DirectDev() was returning bridge.brname (which happens to share the
same spot in the union with direct.linkdev) if actual->type was
'bridge', and ...BridgeName was returning direct.linkdev when
actual->type was 'direct'.
How does this involve Bug 881480 (which was about the inability to
switch between two networks that both have "<forward mode='bridge'/>
<bridge name='xxx'/>"? Whenever the return value of
virDomainNetGetActualDirectDev() for the new and old network
definitions doesn't match, qemuDomainChangeNet() requires a "complete
reconnect" of the device, which qemu currently doesn't
support. ...DirectDev() *should* have been returning NULL for old and
new, but was instead returning the old and new bridge names, which
differ.
(The other two functions weren't causing any behavioral problems in
virDomainChangeNet(), but their problem and fix was identical, so I
included them in this same patch).
were supposed to only return non-0 values when

[libvirt] [PATCHv2 0/2] qemu: support live update of an interface's filter
by Laine Stump
These two patches enable making a live change to the nwfilter of a
guest's interface via virDomainUpdateDeviceFlags (virsh
update-device).
Differences from V1:
1) add patch from Stefan Berger to do a proper comparison of the
values stored in the filterparams hashtable.
2) simplify virNWFilterHashTableEqual to use Stefan's new function, and
remove a couple of pointless comparisons based on Stefan's review.

[libvirt] [PATCH] virsh: Report errors if arguments of the schedinfo command are incorrect
by Peter Krempa
Libvirt's helper API's when called directly don't raise the error so
that virsh remembers it. Subsequent calls to libvirt API's might reset
the error.
In case of schedinfo virDomainFree() in the cleanup section resets the
error when virTypedParameterAssignFromStr() fails.
This patch adds function vshSaveLibvirtError() that can be called after
calling libvirt helper APIs to ensure the error is remembered.

[libvirt] [PATCHv2 0/3] IPv6 enhancements; put dnsmasq parameters in conf-file
by Gene Czarcinski
Rebased 30 Nov 2012
These three patch files are packaged together because they serially
depend on each other. These files have been rebased to "v3" of
the dnsmasq capabilities and bind-dynamic patches.
The DHCPv6 support checks dnsmasq's version and requires a minimum of 2.64.
Also, using dnsmasq for providing the RA service is checked against the
dnsmasq version and is currently 2.64.
As with IPv4, IPv6 DHCP is only one subnetwork on an interface. Additionally,
if other IPv6 addresses are defined, a warning message is issued since
the Router Advertisement service will support only state-full (DHCP) or
state-less (SLAAC) addressing on a network interface (not both). Thus, the
additional subnetworks will need to be manually configured to properly function.
If dnsmasq provides the RA service, it also points to itself as a RDNSS
(Recursive DNS Server) as part of the information is supplies.
If IPv6 DHCP is not being run, then SLAAC addressing is supported for
any IPv6 addresses specified.
Gene Czarcinski (3):
v1: allow guest to guest IPv6 without gateway definition
v8.1 add support for DHCPv6
v7.9: put dnsmasq parameters into conf-file
