[libvirt] [PATCH] qemu: Don't update count of vCPUs if hot-unplug has failed
by Peter Krempa
After live change of cpu counts, the number of processor threads is
verified. This patch makes use of this approach to check if qemu ignored
the request for cpu hot-unplug and report an appropriate message.

[libvirt] [PATCH 00/10] Resolve CHECKED_RETURN errors found by Coverity
by John Ferlan
Bug: https://bugzilla.redhat.com/show_bug.cgi?id=880388
This set of patches resolves the "CHECKED_RETURN (CWE-252)" errors found
by Coverity.
John Ferlan (10):
interface: Check and handle error for virAsprintf() calls.
parallels: Check and handle error for virAsprintf() calls. Ignore the return
inparallelsMakePoolName() since subsequent check validates name
was allocated.
rpc: Check status when attempting to set SO_REUSEADDR flag on outgoing
connection. On failure, VIR_WARN(), but continue to connect.
vmware: Ignore the return status check for vmwareUpdateVMStatus in
convenience routine vmwareDomainObjListUpdateDomain
xen: Check return status for setting TCP_NODELAY option and generate a
VIR_DEBUG message on failure. Allow connection to continue.
virlockspacetest: Check return on mkdir for LOCKSPACE_DIR
vmx2xmltest: Check and handle error for virAsprintf() calls.
xml2vmxtest: Check and handle error for virAsprintf() calls.
virsh: Ignore error returns for virBufferTrim().
phyp: Check and handle select() errors from waitsocket().

anyone with pdwtags installed:
make[3]: *** No rule to make target `lxc_protocol-structs', needed by `check-protocol'. Stop.

[libvirt] [PATCH 0/8] *Persistent vHBA support in storage pool
by Osier Yang
This is the 3rd part to implement NPIV migration support [1].
Part 1:
https://www.redhat.com/archives/libvir-list/2013-January/msg00859.html
Part 2: (Already ACKed by Michal)
https://www.redhat.com/archives/libvir-list/2013-January/msg00859.html
The patches are based on Part 2.
The new XMLs might be too long, might be deserved to have them as
sub-elements of <adapter>. But I'd like to see the feedback first.
Osier Yang (8):
New XML attributes for storage pool source adapter
storage: Make the adapter name be consistent with node device driver
storage: Move virStorageBackendSCSIGetHostNumber into iscsi backend
phyp: Prohibit fc_host adapter for phyp driver
util: Add helper to get the scsi host name by iterating over sysfs
util: Fix bug of managing vport
storage: Add startPool and stopPool for scsi backend
storage: Guess the parent if it's not specified for vHBA

[libvirt] Libvirt node is not getting booted through network
by Varun Bhatnagar
Hi,
I am trying to boot my node through network with the following
configuration:
But I am getting an error message saying:
Even my network setting is not getting reflected in the Virtualbox.
Can anyone suggest me what is wrong with this configuration. I think to
boot a node from network we need to define a boot server but where shall I
add that, I am confused....
Any help will be appreciated. Thanks in advance.
Regards,
Varun
