Issue with kernel 2.6.32-573.3.1.el6.x86_64?
by Michael Kleinpaste
So I patched my vhosts and updated the kernel
to 2.6.32-573.3.1.el6.x86_64. Afterwards the networking became unstable
for my vyatta firewall vm. Lots of packet loss and out of order packets
(based on my tshark at the time).
Has anybody else experienced this?

oVirt 4.0 wishlist: oVirt Engine
by Giuseppe Ragusa
Hi all,
I go on with my wishlist, derived from both solitary mumblings and community talks at the the first Italian oVirt Meetup.
I offer to help in coding (work/family schedules permitting) but keep in mind that I'm a sysadmin with mainly C and bash-scripting skills (but hoping to improve my less-than-newbie Python too...)
I've sent separate wishlist messages for oVirt Node and VDSM.
oVirt Engine:
*) add Samba/CTDB/Ganesha capabilities (maybe in the GlusterFS management UI); there are related wishlist items on configuring/managing Samba/CTDB/Ganesha on oVirt Node and on VDSM
*) add the ability to manage containers (maybe initially as an exclusive cluster type but allowing it to coexist with GlusterFS); there are related wishlist items on supporting containers on the oVirt Node and on VDSM
*) add Open vSwitch direct support (not Neutron-mediated); there are related wishlist items on configuring/managing Open vSwitch on oVirt Node and on VDSM
*) add DRBD9 as a supported Storage Domain type, HC/HE too, managed from the Engine UI similarly to GlusterFS; there are related wishlist items on configuring/managing DRBD9 on oVirt Node and on VDSM
*) add support for managing/limiting GlusterFS heal/rebalance bandwidth usage in HC setup [1]; this is actually a GlusterFS wishlist item first and foremost, but I hope our use case could be considered compelling enough to "force their hand" a bit ;)
Regards,
Giuseppe
[1] bandwidth limiting seems to be supported only for geo-replication on GlusterFS side; it is my understanding that on non-HC setups the heal/rebalance traffic could be kept separate from hypervisor/client traffic (if a separate, Gluster-only, network is physically available and Gluster cluster nodes have been peer-probed on those network addresses)

ovirt-engine-sdk-python too slow
by John Hunter
Hi guys,
I am using the ovirt-engine-sdk-python to communicate with the ovirt-engine,
I am ok to list the vms but the processing time is too long, like 4.5
seconds,
and this line:
from ovirtsdk.api import API
take almost 3 seconds.
This seems a little bit longer than I expected it to be, so I am asking is
there
a quicker way to communicate with the ovirt-engine?

Install ovirt locally
by John Hunter
Hi all,
Here is my situation: in my office, we can not access the website out of
China,
I have to grab my PC home to install the ovirt environment, this makes me
sad.
Can I download all the packages needed by ovirt at home, store them in my
U-disk, and back to office and install the enviroment? I am worry about the
package dependency.
Does anybody who has done this or does anybody has a better solution for
this?
Any help would be appreciated :)

Networking fails for VM running on Centos6.7.Works on Centos6.5
by mad Engineer
hello all i am having strange network issue with vms that are running on
centos 6.7 ovirt nodes.
I recently added one more ovirt node which is running centos6.7 and
upgraded from centos6.5 to centos6.7 on all other nodes.
All VMs running on nodes with centos6.7 as host Operating system fail to
reach network gateway,but if i reboot that same host to centos6.5 kernel
everything works fine(with out changing any network configuration).
Initially i thought it as configuration issue but its there on all nodes.if
i reboot to old kernel everything is working.
I am aware about ghost vlan0 issue in centos6.6 kernel.Not aware about any
issue in centos6.7 Also all my servers are up to date.
All physical interfaces are in access mode VLAN connected to nexus 5k
switches.
working kernel- 2.6.32-431.20.3.el6.x86_64
non working kernel- 2.6.32-573.8.1.el6.x86_64
Any idea?

3.6 vm from template with cloud-init. Not able to confirm OK button
by Gianluca Cecchi
Hello,
I have created a template based on a CentOS 7.1 VM where I installed
cloud-init.
Now I'm trying to create a VM from that template using cloud-init and
changing hostname and network parameters.
It seems that in "Initial Run" section there is something wrong because if
I press OK it doesn't happen anything but a sort of dotted square around
the ok button, but I'm not able to see what is the thing that is not ok and
correct it.....
Can I debug anywhere?
BTW: if I succeed in this preliminar test I would like to create a vm pool
from this same template where, for every started VM in the pool (stateless
is ok for them), a new hostname and a preconfigured static ip is set (I
have not and I can't set up a dhcp server on that network). Is something
configurable in vm pool with cloud init?
Thanks
Gianluca

oVirt 4.0 wishlist: oVirt Self Hosted Engine Setup
by Giuseppe Ragusa
Hi all,
I go on with my wishlist, derived from both solitary mumblings and community talks at the the first Italian oVirt Meetup.
I offer to help in coding (work/family schedules permitting) but keep in mind that I'm a sysadmin with mainly C and bash-scripting skills (but hoping to improve my less-than-newbie Python too...)
I've sent separate wishlist messages for oVirt Node, oVirt Engine and VDSM.
oVirt Self Hosted Engine Setup:
*) allow virtual hardware customizations for locally-created Engine vm, specifically: allow to add an arbitrary number of NICs (asking for MAC address and local bridge to connect to) and maybe also an arbitrary number of disks (asking for size) as these seem to be the only/most_useful items missing; maybe the prebuilt appliance image too may be inspected by setup to detect a customized one and connect any further NICs to custom local bridges (which the user should be asked for)

Giuseppe
