If this proposal is accepted (see my comments below about both
proposals), one solution might be to get rid of the network details
tooltip. Most people probably don't use MTU,


Just a FYI there Lior; we do:) And when 10GbE becomes available, Jumbo Frames 
is going to be required to use all that bandwidth. Otherwise you are capped at 
about half(500MB/s as opposed to 1,2GB/s).

and the rest is just
explaining the network role icons; so maybe not that useful.

That sounds bad to me regardless of the other alternatives.

I like the gear icon because it's noticeable and easily recognizable.
However, keep in mind that bonds should also have the same icon to keep
a consistent design. Now imagine a configuration with several bonds on
the left-hand-side and quite a few networks on the right-hand-side; I'm
no designer, but it could get cluttered with all those gear icons.

It MIGHT be preferable to use the other design (tooltip with action bar)
and risk the odd person not easily finding it (no disrespect intended,
Jason). I have no idea, however, if it's gonna be just the odd person or
most people. I'd love to hear others' opinions.

Hi,

This is about attempting to address the difficulty of finding the edit-action in
the Setup Host Network dialog, as documented in "Bug 984737 - usability: 
webadmin
difficulty in assigning client ip, no gateway possible" in bugzilla.
We have a suggestion from Eldan (see attached 
"HostSetupNetworks-HoverPopUp.png")
which was described in the BZ (comment #3) and seemed acceptable by the reporter
(comment #4), however IIUC - one of the main pain points described in the BZ was
the fact that the user could not find the option to Edit the connection 
properties
since he was looking in the wrong place, and needed to hover on the correct 
place,
in order to find that option.
So although the idea is somewhat helpful, my concern is that this solution is 
not
enough (comment #5).

Another proposal from Malini (comment #6) is to add an "actions" drop-down menu 
in
the form of a small "gear" icon-button - see attached 
"HostSetupNetworks-DropDownMenu.png".
This proposal addresses my concern, however I have a question about another 
concern
with this solution:
would the actions-drop-down menu-items panel be revealed appear upon click or 
upon
hover?

if it will be upon hover, it might seem weird/be conflicted/be somewhat 
confusing
with the hover functionality that reveals the logical-network details pop-up.
The suggestion from Lior did include redesigning the tooltip frame to 
include an "Edit" command, which is certainly more intuitive than a 
pencil.   That being said, I do agree that the gear solution which has 
been proposed is *more* intuitive and honestly more in line with what I 
was expecting.  I didn't complain about Lior's response even though it 
didn't completely address my issue because it came from a designer, and 
I realized, looking at my desktop, that configurable elements often *do 
not* have hints that they are configurable.

if it will be upon click, it means that in order to edit a logical network, two
clicks will be required in order to get to the edit dialog, as opposed to one 
click
in the current state and in Eldan's suggestion.
maybe having two clicks in order to get to the edit dialog is acceptable, 
however
there may be some solutions for that:

one possible solution would be to combine both attached suggestions, i.e. the 
actions
within the hover pop-up, as well as the actions drop-down menu, however it 
means that
there will be some redundancy of the actions availability.

That sounds bad to me regardless of the other alternatives.


another possible solution is to keep only the gear + down-arrow icon (or maybe 
only
the down-arrow icon), without the actual drop-down menu there, just in order to 
indicate
that there are some options available in that area, and have Eldan's pop-up 
appear when
hovering on that icon (or even on the entire logical-network area, as happens 
today with
the current details pop-up)

thoughts?

I like the gear icon because it's noticeable and easily recognizable.

Having not used bridging/multiple VLANS prior to my experimentation with 
ovirt, it's always been the network interface itself that I have 
configured with IP/subnet/etc (eg. 
/etc/sysconfig/network-scripts/ifcfg-eth0).  Most of my machines 
(hundreds) have single network interfaces, and I've never needed to use 
bonding/bridging/etc which kept my network configuration very simple.  
After experimenting with oVirt, and doing my share of reading, I 
certainly understand the concept of logical networks and their 
configuration with oVirt, and yes, it all makes a lot of sense NOW 
(well, except for the fact that really when it comes down to it, the 
Linux configuration for anything but basic networking is, in my opinion, 
anything but intuitive.)  Nonetheless, please keep in mind that a 
concept which might be completely crystal clear to someone who uses it 
on a daily basis might be a little less intuitive to someone who is 
using it for the first time.  Fortunately, I've got *plenty* of patience. :)

Einav

Hm, this makes sense.
I managed now to create a payload cd and can also access it from my vm
as expected.

Re: [Users] received packet with own address as source address

While I see the messages even with no VMs running, I don't see any messages 
before installing oVirt. Additionally, is there any reason that the school 
network would selectively affect some nodes but not others?

1. Following the discussion at users this week about clustered engine + load 
balancing, what about a feature in which each engine will manage X data centers 
(let's call this a "site" - I took the term from past experience), but using 
the web admin you will be able to view/manage data centers that belong to 
different "sites"?

2. Keystone authentication?

Re: [Users] so, what do you want next in oVirt?

[Dotan Paz]

Hi Itamar , 
I would be happy to throw in an idea . 

I think oVirt is lacking the ability to assign permissions on multiple VMs at 
once . 
For example , if I want to grant permissions to a certain user on 30 
VMs , I need to do it manually (or with some script). 
I think this feature is essential for an enterprise aimed product. 
Also it would be really cool to have an ability to create groups within oVirt 
and not in the directory, and 
grant a group permissions on a vm instead of adding them one by one . 
For example , creating a group called Dev and give the group 
permissions on all relevant VMs instead of adding each user one by one . 


Hope to see this feature in the next versions . 
Thanks, 


Dotan Paz ,

Subject: [Users] so, what do you want next in oVirt? 

earlier in the year we did a survey for feature requests / improvements 
/ etc. 

since a lot of things were added, and priorities usually change, I'd 
like to ask again for "what do you need the most from oVirt / what are 
your pain points" next? 

below[1] I've listed my understanding of what already went in from 
previous survey requests (to various degrees of coverage). 

Thanks, 
Itamar 

[1] from the top 12 
V Allow disk resize 
V Integrate Nagios/Zabbix monitoring - via a ui plugin 
V Highly Available engine - via hosted engine[2] 
V Open vSwitch integration - via neutron integration 
X Allow cloning VMs without template 
? Enable hypervisor upgrade/updates through engine[3] 
V Allow engine on an oVirt hosted VM - via hosted engine[2] 
V Enable guest configuration (root password, SSH keys, network) via 
guest agent in engine - via cloud-init 
X Integrate v2v into engine 
? Bond/extend ovirtmgmt with a second network for HA/increased 
bandwidth[4] 
X Integrate scheduling of snapshots and VM export for backups in 
engine[5] 
V Spice – support Google Chrome - via mime based launch 


Other items mentioned in previous survey which should be covered by now: 
- Fix timeout when adding local host during all-in-one configuration 
- Fix engine set-up when SELinux is disabled 
- Provide packages for el6 (CentOS, Red Hat Enterprise Linux) 
- Allow multiple VMs to be deployed from the same template at the same 
time 
- ISO domains on local/GlusterS 
- Show IP addresses in Virtual Machines->Network Interfaces 
- OpenStack Quantum support (now called Neutron) 
- noVNC support 
- Support spice.html5 and websocket proxy 
- Add other guest OSes to list 
- Port oVirt guest agent to Ubuntu[6] 
- SLA - Allow resource time-sharing 
- Spice - Mac client (via mime based launch) 
- Spice - port XPI plug-in to Windows (not sure this will happen, but 
mime based launch allows using firefox now) 
- Spice - client for Ubuntu/Debian (should be covered via mime based 
launch) 


[2] hosted engine is in active development, but not released yet. 
[3] host update is supported, but not for general yum update. 
[4] a lot of improvements were done in this space, but i'm not sure if 
they cover this exact use case 
[5] backup api is now being pushed to master, and orchestration of 
backups should probably happen via 3rd part backup vendors? 
[6] I'm not sure packaging exists yet, but ubuntu is covered for the 
basic functionality of the guest agent.

can you explain the use case a bit?

I have 4 graphic workstations with 3 graphic cards on each. I wanna
passthrough graphic cards to the VMs one by one, since one workstation
has only 3 cards,  I must limit the number of running VM on a host to 3.


1. I assume you use a hook for the graphic passthrough?
you can just fail it if no more devices, and engine will try to 
schedule on next host.


2. (ab)use the reserved RAM. if you allocate to each VM reserved RAM 
so 3 VMs can fit a host but 4 can't, engine won't try to schedule more 
than 3 on the same host as it would violate the reserved rAM


3. not a hook, but a filter. in 3.3 you can write a new filter to the 
pluggable scheduler of "MaxNumberOfVms" and pass a property of 3 to it.

Thank you very much, I think the filter is very suitable for this senerio.

Now from the client C1 which cert should i place in
/etc/pki/CA/cacert.pem so that i can access from the client using the URI
qemu+tls://ovpxen.ind.hp.com/system .
  Please note the host IWFVM00772.hpswlabs.adapps.hp.com
 is ovirt managed host. It is
not the client.


My problem here is i can't change the hypervisor hosts as there are too
many of them and it is configured by vdsm . What certs should i take
from host so that i can use it in the client so that i can connect to
multiple hosts from the client using virsh or virt-manager . I need tls
as remote protocol as i'm trying to automate commands.



you should be able to do read-only access without special config iirc.
taking actions requires the vdsm password, but worth discussing if you 
want to take actions under the feet of vdsm what they would be.

there are actually a lot of tables that have a reference to the image in

I am adding Liron who might be able to give you the patch needed for

[Dafna Ron]

deleting illegal objects from UI was added to the latest ovirt/vdsm
are you getting any errors when trying to delete them now?

Re: [Users] received packet with own address as source address

[Assaf Muller]

I'd enable STP on all ports, including the port connecting your switch to the 
school switch.

VSDSM configures the ovirtmgmt bridge on installation. The reason I'm 
suggesting that it's not VDSM at fault but rather the school network having a 
loop is that you mentioned
that you get these messages even with no VMs running.

The switch is connected to the internet via the school's switch. Currently (as 
well as when I received the error messages last time) portfast is disabled for 
all ports, and STP enabled for all ports except for the port connecting my 
switch to the school's.

Absolutely agree that this would be the best solution, but unfortunately
there's no config option for openibd to use credentials when connecting
to libvirt :(

I have 4 graphic workstations with 3 graphic cards on each. I wanna

Hi,

Does anyone have oVirt (or a plain KVM hypervisor) running on Infiniband
where the virtual machines are bridged to an Infiniband interface (with
EoIB kernel module)?


As far as I recall the EoIB module is not yet in upstream kernel. Could
you give more details on your setup (distro, kernel, module)?
Do you get connectivity between the hosts? Maybe Itzik and his
colleagues could help us here.



Thanks for your answer.

That's right - EoIB isn't in the kernel.
I installed module from Mellanox OFED package and even there it's marked as 
unstable...
OS is CentOS 6.4.

At the moment I've also an open support case with Mellanox trying to solve the 
connectivity issue.
So I have support from official site, but was thinking maybe someone has 
already experience with such a setup and also had some issues/tipps for me...

My problem is some sort of a bridge or maybe MAC translation issue (unsure 
cause of a lot of unanswered ARP requests in tcpdump and bridge is working on 
Ethernet interfaces).
I have bridge ovirtmgmt on eth2 interface (eth2 is a (virtual) ethernet 
interface bound to the Infiniband-interface) with an IP address configured on 
it.
Hosts can reach each other, so ethernet to infiniband translation seems to work.
But when I create a vm in oVirt this vm can only communicate with IPs/vms on 
the bridge.
This mean I can ping the IP of the host and other vms on this bridge, but no 
host behind the bridge (like e.g. other hosts or vms on other hosts)...




Mellanox support team found the issue:
Daemon openibd requires write access to libvirt which is restricted by
oVirt per default.

When changing auth_unix_rw to "none" networking of the vms is working fine
over the inifinband network.

So my question is now:
I think there's a good reason why write access to libvirt is restricted.
In my particular setup no one will do a virsh start/stop/whatever so
from a user point I can live with an open libvirt.

But are there any troubles I can run into from oVirt side with
auth_unix_rw="none" beside users doing evil virsh stuff?

Today I tested it and ran into a first issue which I didn't investigate
so far (will do this week):
- Started vm from oVirt on node
- Changed auth_unix_rw to "none"
- Restarted libvirt on node
- VM was running according to "virsh list"
- VM was stopped in oVirt
- Started vm in oVirt on another node
- vm was running twice
Will have a look at the logs what append exactly this vm...



isn't the right thing is to configure openibd to use same credentials 
vdsm is using (or with their own credentials)?






Regards,
René






I'm having issues in such a setup where vms can't communicate over this
bridge...

René

Re: [Users] cant remove disks from iscsi domain

you said that the disks are deleted although an exception is given but

I think that I remember a bug reported and fixed on that as well but I 
can't seem to find it.

What we need to understand is how did we get into
this state; Did you have network issues or relevant crashes?
Well, I had a few power loss events (its my test env, so no ups 
installed yet) with storage, engine and nodes powered off unclean; my 
storage is kinda slow - just raid5 from 3 sata hdd. But there were no 
network issues i'm aware of, iscsi network is in separate vlan with 
1gbps physical.

Apart from power loss events I had no crashes of engine or nodes.

Yuri,
just to clarify the quota part, the stack trace you provided
was resolved as the bz Greg described- 
https://bugzilla.redhat.com/show_bug.cgi?id=905891

This is unrelated to the storage issue, as the quota caching
is an independent procedure running in parallel.

So what we now need to focus on is this part:
[Errno 2] No such file or directory:
'/rhev/data-center/mnt/blockSD/d786e2d5-05ab-4da6-95fc-1af791a3c113/images/5344ca63-302a-43de-9193-da7937fbdfad/dfefc573-de85-4085-8900-da271affe831'

What we need to understand is how did we get into
this state; Did you have network issues or relevant crashes?
