Re: [Users] Bug: adding LocalStorage Data Centers
Hi Maor, thanks for this hint. It definitely could be some kind of an issue of that bug. Iirc we had this error in our logs but I also tried to change the path - same results. I'm also curious about the fact that the first two host have this same path and they work. If I delete one of those I can add another one but the deleted host can't be readded until I delete another one (no matter what node you select). btw: Our storage connection output was ok - one connection per domain - no orphan connections. Fabian Deutsch already assumed that it might have been a bug with a non deleted storage connection. Sadly that wasn't the reason. The sc output posted by Sven was from a later stage of this project where we already had experimented with several export domains. The "local storage bug" occured before that with a fresh installation of oVrit 3.3. Regards Daniel PS: I work with Sven on the same project.

[Users] Default route on hosts
Before I ask my question, I want to make sure I'm using the right terms: engine == the system that manages the ovirt environment. Runs the web interface, etc host(s) == the physical machine(s) the engine uses to deploy virtual machines on. Sometimes referenced as a node? vm(s) == the guest systems that are controlled by the engine and run on the hosts, that do the stuff you present to the world at large, whatever your world at large would be. Is that correct? In my environment, I have a customer facing network and another network that's on a set of isolated switches. I desire to use the isolated network as the management network, and am naming the other network "public" in the web management interface. In the interface, I see these labeled as ovirtmgmt and public, for the management network (private) and the customer facing network (public). >From what I can tell from poking at the configuration files, and from a couple >references in other threads, the 'DEFROUTE' setting in the ifcfg-* files gets set to 'yes' only for the ovirtmgmt network, not for any other bridged network. I can override this by hand as I deploy hosts, but am hoping for a way to do so within the ovirt management framework, so I have less bits that can go wrong. Is there a way for me to get the DEFROUTE set to no for the ovirtmgmt interface and to yes on the public interface as I deploy hosts? Is there a reason I'm not seeing for avoiding this behavior? --Chris ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [Users] oVirt-guest-agent EL6 vioserial question
Hi, well I don't know what you really try to achieve? Your first question assumed that virtio serial was missing and you wanted to know how to install it. It turned out, it is installed, so what do you want to achieve exactly through virtio-serial? if the guest agent reports the ip to engine then virtio_serial should work as expected (afaik, I'm no ovirt-dev!)

Re: [Users] Live storage migration snapshot removal (fails)
I can open a bug on this. Should I file it for the entire "snapshot removal fails"-problem or just this error? I've looked at the parsing error and the problem seems to be that the qemuImg.check() function expects a qemu-img version that outputs a string like: "Image end offset: 262144". The only version I could find that does that is the one in the F19 virt-preview repository. Stock F19 qemu-img doesn't have this output. Nor do the stock EL6 or qemu-img-rhev EL6 versions. The only function that calls qemuImg.check is blockVolume.shrinkToOptimalSize() this function needs (and uses) the parsed offset to shrink the LV containing the qcow2 image.

Re: [Users] *SAN LUNs* thin-provisioning : Reclaiming block device storage
On 11/05/2013 09:49 AM, Nicolas Ecarnot wrote: [This post is *not* about *VM* thin-provisioning] Hi, Our setup is made of an Equalogic SAN (PS6100) connected via a dedicated iSCSI network, an oVirt 3.3.0-4.el6 manager and CentOS nodes. This is working fine (thank you all). I usually create a LUN for the master storage domain, configure in thin-provisioned mode on the SAN side, and fill it with VMs until it reaches some 90%. Then I create another LUN the same way, add it as an additional storage domain, move some VM on it from the first domain and it's OK. The issue there is I have no mean to reclaim any freed storage on the master storage LUN. So the question (not *master* domain specific - any storage domain is concerned) is how to reclaim space on these domains. I began to have a closer look at how a storage domain is setup (PV, VG, LVs). I also found some hints about some mount option (unmap) that could be passed when mounting ext4 filesystems. But I guess the issue is way more complex, as LVM may add a layer between ext4 and the block device. How is the LVM setup working? I saw there was one LV by disk (and some metadata LVs), in one big VG in one big PV. Is the entire disk space allocated for the PV, or is only a partial of it is used first, then an extension (growing) is made each time some more space is needed by adding VMs? I have the opportunity to test and play with a test LUN in a test oVirt, so I fear no crash. If the only answer is "Unavailable feature", it's ok, but I just have to know. other than the LV for the masterfs, there is a disk for each "volume" (disk or snapshot). a snapshot is copy-on-write and usually thinly-provisioned. a disk can be pre-allocated or thinly provisioned. a thinly provisioned is done by creating a small LV, then extending it as-needed while the VM is running. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Correct, new URI layout takes effect in oVirt 3.4, not sure about RHEV but I
think "ovirt-engine" in URI might change there.

I assume the URI layout change BZ [https://bugzilla.redhat.com/961677] will
have some release notes attached.
For UI plugins, I was talking with Alon about this, we could promote the use of
relative URIs to make UI plugins unaware of absolute URI layout.
For example, in plugin descriptor:
"url": "plugin/ExamplePlugin/start.html" // relative to WebAdmin base context
path, i.e. /ovirt-engine/webadmin
would result in:
custom content could be added like this:
api.addMainTab('Example Tab', 'example-tab', 'plugin/ExamplePlugin/tab.html');
and any content within the iframe (either start.html or tab.html) could use:
