[PATCH] [TEST] Fix VSMS 09_procrasd_persist and 11_define_memrasdunits
by Eduardo Lima (Etrunko)
From: Eduardo Lima (Etrunko) <eblima(a)br.ibm.com>
Both tests were failing due to reusing an instance of the class for defining
domains in a loop. The error message was the following:
ERROR - Got CIM error CIM_ERR_FAILED: ResourceSettings Error: VirtualDevice
property must be unique for each DiskResourceAllocationSettingData in a
single guest with return code 1
A recent change in XenKvmLib/vxml.py necessary for the new test
32_modify_cdrom_media.py triggered this bug. To avoid this error we simply
create a new instance of that class in each iteration of the loop.

[PATCH] Avoid connection to libvirt if previous attempt fails
by Eduardo Lima (Etrunko)
From: Eduardo Lima (Etrunko) <eblima(a)br.ibm.com>
This is a workaround to avoid libvirt flooding error messages in syslog. This
happens often if a client submits queries for CIM_ superclasses, which then will
translate to a query for each registered class. In our case KVM_, LXC_ and XEN_.
Ideally, there should be a way to ask libvirt if a given URI or hypervisor is
enabled/supported. A patch for that feature is on the works, and as soon as it
is integrated to libvirt tree this feature will be updated.

[PATCH] Fix qos bug when retrieving SettingsDefineCapabilites RASDs for primordial Network/0 pool
by Gareth S. Bestor
# HG changeset patch
# User Gareth S. Bestor <bestor(a)us.ibm.com>
# Date 1320049754 25200
# Node ID e1660ac9b5fc44b863b438b6b483edf66784453e
# Parent 862bcd60ae449932205b15ba42b37e06e6834de4
Fix qos bug when retrieving SettingsDefineCapabilites RASDs for primordial Network/0 pool
For some reason, when retreiving at SettingsDefinesCapabilites for only the
primordial network pool 'Network/0' the qos code is called for the
'Minimum' RASDs (?!), which because the associated ID is a constant causes
the string substitution code for renaming the qos 'Point/...' RASDs to
crash. This patch fixes this qos code so that the InstanceID string is only
manipulated for Point RASDs.

It first looked like the problem mentioned here @
https://bugs.launchpad.net/ubuntu/+source/libgcrypt11/+bug/751142
But trying to update libgcrypt via apt-get says I already have the latest
library installed and apt-get does nothing.
I also put this obs and some workarounds I tried to get over this issue in
the launchpad defect, hoping to see some response.
I would like to know if anybody can point me to what i am missing
thanx,

[PATCH] Patch to add network qos (bandwidth) support for KVM guests using tc
by Gareth S. Bestor
# HG changeset patch

Patch to add network qos (bandwidth) support for KVM guests using tc
This patch adds network qos support into libvirt-cim for setting network
bandwidth limits on KVM guests' MAC addrs, using existing tc (traffic control)
host support. Patch is a bit hack-ish because it is mostly for older versions
of libvirt which do not have any qos support in libvirt itself. I am finishing
a new, and cleaner, patch to libvirt-cim that will exploit the native support
for qos present in latest libvirt versions.
Patch is a bit ugly because (1) it must manage all the qos data associated with
KVM guest's network device completely *outside* of libvirt (since no support
and existing mgmt data available to handle this in older libvirts).
And (2) because the tc commands themselves needed to query, retreive, add and
delete tc bandwidth setting for a MAC addr are themselves quite messy scripts.
This patch assume all the necessary tc performance classes have been setup
externally.
Because it must screen-scrape tc command output to get
performance class and associated bandwith values, this patch will be very
sensitive to change in output format of tc commands. It has been tested
successfully on RHEL6.1.
I dont not recommend exploiting this new feature unless you know
what you are doing...

When I wrote "older rev" above, I meant rev 879.
I did not see 31_ and 32_ in rev 879 and that is understandable since those
tests were added in later rev.
I am trying to understand why above tests are failing with 883 + cimtest
patches on list (the three I pointed out above)?
