[Engine-devel] oVirt and Quantum
by Gary Kotton 22 May '12

22 May '12

Hi, As part of a POC we have integrated Quantum (http://wiki.openstack.org/Quantum) into oVirt (http://www.ovirt.org/) This has been tested with the OVS and Linux Bridge plugins. The details of the integration can be found at - https://fedoraproject.org/wiki/Quantum_and_oVirt. Any comments and suggestions would be greatly appreciated. Thanks Gary

[Engine-devel] Storage Device Management in VDSM and oVirt
by Shireesh Anjal 09 May '12

09 May '12

Hi all, As part of adding Gluster support in ovirt, we need to introduce some Storage Device management capabilities (on the host). Since these are quite generic and not specific to Gluster as such, we think it might be useful to add it as a core vdsm and oVirt feature. At a high level, this involves following: - A "Storage Devices" sub-tab on "Host" entity, displaying information about all the storage devices* - Listing of different types of storage devices of a host - Regular Disks and Partitions* - LVM* - Software RAID* - Various actions related to device configuration - Partition disks* - Format and mount disks / partitions* - Create, resize and delete LVM Volume Groups (VGs) - Create, resize, delete, format and mount LVM Logical Volumes (LVs) - Create, resize, delete, partition, format and mount Software RAID devices - Edit properties of the devices - UI can be modeled similar to the system-config-lvm tool The items marked with (*) in above list are urgently required for the Gluster feature, and will be developed first. Comments / inputs welcome. Thanks, Shireesh

[Engine-devel] Updating ovirt engine from 3.0 to the 3.1.0 version
by Shu Ming 02 May '12

02 May '12

Hi, I built a set of ovirt engine RPM packages from near the latest ovirt engine source code. However, when I try to access the engine server with URL "http://ovirt-engine-112:80", the browser displayed a blank page without http error returned. Any clue about what is going on here? Why didn't the engine administrator home page be shown? And the packages were also installed successfully in my target system, checked this by "rpm -q -a|grep engine". I) upgraded the packages to the 3.1 [root@ovirt-engine-112 ~]# rpm -q -a |grep engine ovirt-engine-restapi-3.1.0_0001-1.8.fc16.x86_64 ovirt-engine-dbscripts-3.1.0_0001-1.8.fc16.x86_64 ovirt-engine-log-collector-3.0.0_0001-1.6.fc16.x86_64 ovirt-engine-genericapi-3.1.0_0001-1.8.fc16.x86_64 ovirt-engine-backend-3.1.0_0001-1.8.fc16.x86_64 ovirt-engine-setup-3.1.0_0001-1.8.fc16.x86_64 ovirt-engine-jbossas-1.2-2.fc16.x86_64 ovirt-engine-jboss-deps-3.1.0_0001-1.8.fc16.x86_64 ovirt-engine-config-3.1.0_0001-1.8.fc16.x86_64 ovirt-engine-3.1.0_0001-1.8.fc16.x86_64 ovirt-engine-webadmin-portal-3.1.0_0001-1.8.fc16.x86_64 ovirt-engine-userportal-3.1.0_0001-1.8.fc16.x86_64 ovirt-engine-tools-common-3.1.0_0001-1.8.fc16.x86_64 ovirt-engine-image-uploader-3.1.0_0001-1.8.fc16.x86_64 ovirt-engine-notification-service-3.1.0_0001-1.8.fc16.x86_64 ovirt-engine-iso-uploader-3.1.0_0001-1.8.fc16.x86_64 gtk2-engines-2.20.2-2.fc15.x86_64 Step II) Then I used "engine-setup" to setup the engine.

[Engine-devel] CPU topology in the API
by Simon Grinberg 30 Apr '12

30 Apr '12

Hi list, The current status is that though they look the same, CPU topology for hosts and VMs differ. In both you have <topology cores="N" sockets="Y"/> for hosts: Cores = Total cores on the host, Y=number of sockets for VMs: Cores = Cores per socket, Y=number of sockets This means that for a hosts that has 4 sockets with 8 cores per socket the topology will be presented as: <topology cores="32" sockets="4"/> While for VM with the same requested topology will show: <topology cores="8" sockets="4"/> I think they should not be different to avoid confusion but: * The information we displayed for the host can't count on the fact that cores are distributed evenly across sockets, because theoretically a host could contain several different CPUs, so it can't be displayed as a multiplication. * On the other hand changing the VM topology will break the API though it will make it aligned both with hosts and with the 'New VM' dialogue in the UI. For oVirt 3.x it may be that nothing can be changed however for oVirt it is allowed in theory to break the API (a bit :)) so the options as I see it are: 1. Don't touch, leave the confusion. 2. Make host align to VMs with the risk that on some hosts this may be a bit misleading - should be rare. 3. Make host topology looks like VM but allow multiple CPU topologies in the CPUs sub collection of the host. (This also requires change in VDSM API) 4. Align VMs to Hosts I would go for 4 or 2 Current CPU topology for the hosts is a new commit, thus it may be allowed to change it now since no one is using it yet. This works in favour of 2. In any case only 3 discloses all the information in all possible cases. Thoughts? Thanks, Simon.

[Engine-devel] Moving oVirt engine to Jboss AS 7.1.1
by Oved Ourfalli 29 Apr '12

29 Apr '12

Hey all, We have pushed patches that make the necessary adjustments to allow working with the newest Jboss version, Jboss AS 7.1.1 Final. After fetching please do the following: * Download Jboss AS 7.1.1.Final from http://download.jboss.org/jbossas/7.1/jboss-as-7.1.1.Final/jboss-as-7.1.1.F… * Change the JBOSS_HOME wherever you defined it. * Change the Jboss Home in ~/.m2/settings.xml. * Run a full build, including setup: mvn clean install -DskipTests -Psetup,dep (consider using flags -Dgwt.userAgent=gecko1_8 and -Dgwt.draftCompile=true to avoid compiling GWT on all permutations). * Run jboss as usual. If you have any issues, reply here and we'll do anything to help. The oVirt engine wiki page (http://www.ovirt.org/wiki/Building_oVirt_engine) was changes accordingly. Thank you, Oved

Hi, Just an idea for the gerrit reviews: if you review a patch and give "+1 Looks good to me, but someone else must approve", then please add someone as reviewer, who might be the right person. And then after a while the patch will get to someone who knows if the patch is good or not. Laszlo

[Engine-devel] namingcontexts getting ignored.
by Sharad Mishra 29 Apr '12

29 Apr '12

Hi, I enter "getDefaultNamingContextFromNamingContexts()" with namingContexts set to - namingcontexts: CN=SCHEMA, CN=LOCALHOST, CN=IBMPOLICIES, O=IBM.COM, O=DELETED.IBM.COM But this method only takes the first case "CN=SCHEMA" and ignores the rest. Actually I am interested in "O=IBM.COM". Is this working as designed or needs improvement? -Sharad Mishra IBM public class RootDSEData { private String domainDN = null; private LdapProviderType ldapProviderType = null; private final static String RHDS_NAMING_CONTEXT = "o=netscaperoot"; public static String getDefaultNamingContextFromNamingContexts(Attribute namingContexts) { for (int index = 0; index < namingContexts.size(); ++index) { String namingContext; try { namingContext = (String) namingContexts.get(index); } catch (NamingException e) { return null; } if (!RHDS_NAMING_CONTEXT.equalsIgnoreCase(namingContext)) { return namingContext; } } return null; }

[Engine-devel] upstream/downstream compat
by Ryan Harper 23 Apr '12

23 Apr '12

I've submitted some changes to start some of the work of removing the RHEV/RHEVM names throughout the vdsm code. In one of the patches, there's a good discussion on compatibility with downstream[1] And I wanted to continue that on the mailing list so we could have more eyes; it's not clear to me if everyone is able to see/participate in an inline thread to just one of my patches. To the point; as we look at moving toward an upstream vdsm which may be used stand-alone; ie, it may or may not having ovirt-engine/RHEVM driving actions. I'm interested in hearing details what our requirements for compatibility are and which parts of the tree might be affected. I'd like to posit that downstream compat is the responsibility of the distro versus the upstream community; though that's not a license to make things difficult. IMHO, this means we can do things that help clean up the code or move the project in a particular direction without having to always worry about what the package looks like in a particular distro. The other aspect to compatibility I'd like to hear details/discussion on the interfaces (explicit or implicit) between vdsm and ovirt-engine. I rekindled a discussion[2] on at least one known issue around engine including the qemu machine type in the database; Any pointers to other places would be helpful as I'm wrapping my head around the back and forth between vdsm and engine. 1. http://gerrit.ovirt.org/#patch,unified,3287,1,vds_bootstrap/vds_bootstrap.py 2. http://lists.ovirt.org/pipermail/engine-devel/2012-April/001209.html -- Ryan Harper Software Engineer; Linux Technology Center IBM Corp., Austin, Tx ryanh(a)us.ibm.com

[Engine-devel] StorageHelperDirector "factory" and StorageType
by Yair Zaslavsky 23 Apr '12

23 Apr '12

Hi all, StorageHelperDirector.java implements a mechanism that creates instances of classes implementing IStorageHelper based on String value of StorageType enum. Although the InitializeHelpers method has an "automated" mechanism for creating the helpers, I think it causes some bad practice - It creates a tight coupling between the StorageType values and the class names of storage helpers, and a result of that, Java naming convention is broken (we use upper case enum literals at StorageType which yield class names such as LOCALFSStorageHelper. I think that this mechanism is an overkill, and during addition of new storage type, its easily to detect during development if one has forgotten to add the helper to the factory (if done manually). Thoughts about this issue are more than welcome Yair

Re: [Engine-devel] Floating Disks implementation in REST-API
by Ori Liel 19 Apr '12

19 Apr '12

I'd like us to move forward with this. The option of using 'attach' action does not exist, because, as Eoghan observed, we would be executing an action on an entity which doesn't exist in the collection: (.../api/vms/{vm:id}/disks/???-no entity-???/attach) There are two options left on the table; let's see if we can agree on one of them: 1) POST/api/vms/{vm:id}/disks <disk id="{disk:id}"/> => attach disk DELETE .../api/vms/{vm:id}/disks/{disk:id} <disk><detach>true</detach><disk> => detach disk Pros: symmetrical Cons: risky (if user wants to detach but forgot to give parameter, disk will be deleted). 2) POST/api/vms/{vm:id}/disks <disk id="{disk:id}"/> => attach disk DELETE .../api/vms/{vm:id}/disks/{disk:id}/detach => detach disk Pros: not dangerous Cons: asymmetrical, attach done like add, but detach done using action. No solution is perfect but we need to decide. Thanks, Ori.

[Engine-devel] Jar versions in ovirt-engine
by Ofer Schreiber 19 Apr '12

19 Apr '12

Ever wondered why the version of oVirt's first release is 3.0.0_0001? The answer is simple - We use ovirt-engine jar's version as our "main" release version. Personally, I think the current versioning scheme is ugly. Actually, I can't name even one open-source project using "_" in it's version. What can we do about it? We have couple of options: 1. Leave the engine alone, and use a separate versioning scheme (e.g - use just 3.1.0 as the main version for next release) 2. Remove "_" from engine jars 3. Do nothing. I'd like to hear your thoughts, as well as the reasons to use such an unusual versioning scheme. --- Ofer Schreiber oVirt Release Manager

[Engine-devel] Maven 3 here we come!
by Doron Fediuck 18 Apr '12

18 Apr '12

Hi guys, We're trying to be as updated as possible in oVirt development. In order to catch up with recent changes in major distro's, we'd like to move to Maven 3. Current oVirt engine code actually can be built with Maven 3 now, but we still need to handle some minor issues. Also we need to update our wiki's accordingly. To make this move coordinated, and give everyone some time to play with Maven 3, I suggest we do it in 2 weeks from now, and move on April 29. Basically the code should remain the same, other than minor changes we may need to do. If you have substantials considerations against maven3, please share. -- /d "Who's General Failure and why's he reading my disk?"

[Engine-devel] ovirt-engine deployment method
by Ofer Schreiber 18 Apr '12

18 Apr '12

As decided earlier, oVirt next release (3.1) is targeted for Fedora 17. Since the engine uses JBoss, we have two deployment options: 1. Continue working with ovirt-engine-jbossas package PROS: Single rpm. known upgrade method. CONS: Maintaining un-natural zip based rpm. No official support. Can't be pushed into Fedora. 2. Move to JBoss F17 official packages: PROS: Fully supported F17 rpms (including bug fixes, security fixes, etc). "The right thing to do". CONS: Upgrade from first release (relaying on old jboss) will be almost impossible, Some open issues (will it work just as as normal service? or will we need to code a new one?), Might cause a delay to Feature Freeze. Thought? Comments? Share them with us! --- Ofer Schreiber oVirt Release Manager

[Engine-devel] java enum syntax trick
by Laszlo Hornyak 18 Apr '12

18 Apr '12

Hi, In java enums, you can leave a coma before the semicolon closing the names in the enum. e.g. enum Foo { bar, baz, // <!-- last, still with a coma ; //and there is no more } I don't know if this fits in the code formating requirements, but maybe it could help us to waste less time on merging because you did not have to change the last line to add some more.

I guess this was done because this method is primarily intended to validate the action parameters passed to a BLL action, using the validation annotations on the parameter class. However I think this method can be useful for general use as well. e.g. I cannot add a "@Valid" annotation on a "list" or a "map" in a parameter class. So I need to iterate over the list/map, and validate each element inside the loop. The validation inside the loop can also utilize the above method if the restriction "extends VdcActionParametersBase" is removed.

[Engine-devel] Getting into memory allocation problems in git?
by Yair Zaslavsky 16 Apr '12

16 Apr '12

Hi all, I got a strange error while trying to fetch a patch from ovrit gerrit. The error looked like this - git fetch http://gerrit.ovirt.org/p/ovirt-engine refs/changes/41/3541/1 && git checkout FETCH_HEAD error: Could not resolve host: gerrit.ovirt.org; Cannot allocate memory while accessing http://gerrit.ovirt.org/p/ovirt-engine/info/refs fatal: HTTP request failed Could not find anything interesting in google, and out of despair started to pass on manual of git. I then encountered git gc. My java instincts told me to give it a shot (after all, garbage collection sounds good), and it worked! (Nothing helped before - not removing local branches, not trying to perform this from various branches, etc...) FYI Yair

[Engine-devel] Issue with XML namespaces in engine-setup
by Juan Hernandez 14 Apr '12

14 Apr '12

Hello, The code that we use in engine-setup to modify JBoss AS XML configuration files uses the following pattern: datasourceStr = ''' <datasource ...> ... </datasource> ''' xmlObj.addNodes("//datasource:subsystem/datasource:datasources", datasourceStr) This looks correct but is in fact generating a incorrect XML document, as the tags being added are not associated to a namespace. The resulting XML file will be correct, but the temporary representation in memory is not. This causes problems if you later, before writing out the modified file, try to use xpath expressions matching the added nodes: there will be no match. I would suggest that we change the pattern to something like this: datasourceStr = ''' <any_dummy_tag xmlns="urn:jboss:domain:datasources:1.0"> <datasource ...> ... </datasource> </any_dummy_tag> ''' datasourceNodes = libxml2.parseDoc(datasourceStr).getRootElement().children xmlObje.addNodes("//datasource:subsystem/datasource:datasources", datasourceNodes) This way both the representation in memory and the resulting file are correct. Le me know what you think. Regards, Juan Hernandez -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif. Gorbea 3, planta 3ºD, 28016 Madrid, Spain Inscrita en el Reg. Mercantil de Madrid – C.I.F.

[Engine-devel] Hot-plug of disks and nics
by Ori Liel 11 Apr '12

11 Apr '12

On the subject of activate/deactivate disks and nics ("hot-plug"), I'd like to hear opinions about the correct modelling. I see two possible options (I will use disks as an example, but the chosen modelling should be the same for nics and disks). Option 1 - update: ================= PUT .../api/vms/{vm:id}/disks/{disk:id} <disk> <activated>true</activated> </disk> Pros: ----- * RESTful, no need for new action Cons: ----- * Inconsistent with other flows. We do not normally update status fields to perform actions. For example to run a VM, we do not update it's status to 'activated', we run an action (start). * Enables user to update disk properties AND activate/deactivate in the same operation. Updating certain disk properties is forbidden while the VM is up, but activating/deactivating the disk is allowed always. This requires business-logic in REST-API: if the user activates the disk and changes properties on it - REST-API must first change the properties and then activate the disk (if disk is activated first, update properties will fail). If, on the other hand, the user *deactivates* the disk and changes properties on it - REST-API must first deactivate the disk and then change the properties (changing properties while disk is still active will fail). This bug-prone logic is only necessary because when activate/deactivate is merged with update. Option 2 - action ================= .../api/vms/{vm:id}/disks/{disk:id}/attach Pros: ---- * Less RESTful Cons: ----- * Consistent with other flows * Does not have the drawback of the additional business-logic described above Opinions? Thanks, Ori.

[Engine-devel] Floating Disks implementation in REST-API
by Ori Liel 11 Apr '12

11 Apr '12

The "Floating Disks" feature makes disks into stand-alone entities: a given disk may be attached to a VM (as all disks are today), or it may be not attached to any VM, which makes it a floating disk (http://www.ovirt.org/wiki/Features/FloatingDisk) To implement attach/detach of disk to/from VM in REST-API, we intend to introduce two new actions: POST .../api/vms/{vm:id}/disks/{disk:id}/attach POST .../api/vms/{vm:id}/disks/{disk:id}/detach Since we try not to add new actions unless we have to, I want to explain why I believe that these actions are necessary. The other implementation would use existing add/remove flows: POST .../api/vms/{vm:id}/disks - if the disk was passed with an ID, attach it to this VM. If no id - create a new disk. DELETE .../api/vms/{vm:id}/disks/{disk:id} - *ambiguity problem, need to add a flag* We can't break existing API, so regular DELETE must remove the disk, as it does today. To detach a disk using DELETE we'd have to add a flag to the DETELE command. This is quite risky, because if the user forgets to pass this flag, the disk which he wanted to detach will actually be deleted. Theoretically, if we could break the API, the following modelling would resolve the ambiguity and perhaps be ideal: - POST/DELETE disk in root context means create or delete it. - POST/DELETE disk in VM context means attach or detach it. But we don't have the privilege of breaking the API. Considering all of the above - and the fact that attach/detach nics to/from host is also implemented using actions - I believe that the new actions are justifiable. Any comments? Thanks, Ori

[Engine-devel] "add permission to user" dialog - nothing shown by default
by Einav Cohen 11 Apr '12

11 Apr '12

[https://bugzilla.redhat.com/show_bug.cgi?id=810287] When opening the "add permission to user" dialog, no user is shown in the grid by default; user has to enter something in the search text-box within the dialog (or leave it empty) and hit "Go"; only then the list of users is being filled (according to the search text-box contents). This behavior is by design. Do you think that this behavior should change? i.e. do you think that the users grid should be filled right after opening the dialog with a list of all users? Please consider the following: - calling to the search query and rendering its results may take a while, so user may open the dialog, but will be able to do something only after waiting a while (when originally, all he intended to do was to search a very particular user, which would have taken a short time). - we may have several domains, so grid will be filled with results of the first domain selected (which might not be the domain that the user intended to search originally), so this may be annoying. Due to the reasons above, my personal take is that the current behavior is OK and shouldn't be changed (i.e. BZ should be closed). Any comments?

[Engine-devel] Is there a preferred workflow when adding additional error messages to VDSM _and_ Engine?
by Lee Yarwood 10 Apr '12

10 Apr '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello all, I'm currently working on a patch to correct the logic used by vdsm when reviewing the logical and physical block size of physical volumes [1]. Once/If this is approved I'd like to look into making the exceptions thrown from vdsm and the errors displayed within engine more descriptive. Before I start throwing patches into gerrit I was wondering *if* there is a preferred workflow when adding additional exceptions and error messages across both projects. For example, committing changes to vdsm before engine, engine before vdsm or both at the same time. I'm also wondering if there is a way to say that vdsm gerrit changeid x relies on engine gerrit changeid y etc?

[Engine-devel] deprecating auto-detection of Ldap provider types
by Roy Golan 09 Apr '12

09 Apr '12

auto-detection featured few bugs lately which convinced me that it must be deprecated/removed from the code in favor of adding manual set of the provider type. main reasons for that: a. the provider is type is known by the user b. identifying a provider by the rootDSE attributes is error-prone, not reliable etc... specially if the support matrix is growing c. auto-detection logic is duplicated (and not shared) between the backend code and the manage-domains tool (nevermind the reasons now) A manual set of the provider type requires a new configuration field for a domain and the question is the upgrade path which may look like * set the provider type to default Active Directory (because its more likely to be the provider type) * things not working - use the engine-manage-domains and choose the provider type. * optionally - keep the auto-detection (of the tool only!) if user wants to use it. your suggestion and thoughts... Thanks, Roy

[Engine-devel] qemu machine type / datacenter machine version
by Ryan Harper 08 Apr '12

08 Apr '12

I was playing around with ovirt-engine datacenter definitions and I seems that the capatibility version in the gui controls the qemu machine type specified (3.0 -> pc-0.14). I was wondering where that's configured setup. I grepped through my deployed system and saw a hit here: [root@f16-engine ovirt-engine]# rpm -qf /usr/share/ovirt-engine ovirt-engine-3.0.0_0001-1.2.fc16.x86_64 [root@f16-engine ovirt-engine]# grep -nri "pc-0.14" * db-backups/tmprN1EDt.sql:12119:INSERT INTO vdc_options (option_id, option_name, option_value, version) VALUES (236, 'EmulatedMachine', 'pc-0.14', '3.0'); db-backups/tmpj4XRCI.sql:12138:INSERT INTO vdc_options (option_id, option_name, option_value, version) VALUES (236, 'EmulatedMachine', 'pc-0.14', '3.0'); dbscripts/upgrade/03_00_0530_update_EmulatedMachine_config_to_pc.sql:2:select fn_db_update_config_value('EmulatedMachine','pc-0.14','3.0'); dbscripts/create_db.sh.log:7571:select fn_db_update_config_value('EmulatedMachine','pc-0.14','3.0'); dbscripts/create_db.sh.log:25529:select fn_db_update_config_value('EmulatedMachine','pc-0.14','3.0'); dbscripts/create_db.sh.log:43487:select fn_db_update_config_value('EmulatedMachine','pc-0.14','3.0'); Is there any way to define different compatibiilty versions or edit that? If I've got a new end-point running qemu-kvm that doesn't have pc-0.14 defined (Say RHEL6.x) the machines won't lauch when you specific -M pc-0.14.

[Engine-devel] Purpose of Attached Inactive/Maintenance state of export domain?
by David Jaša 08 Apr '12

08 Apr '12

Hi, As I'm using export domain to shove VMs and templates betweend RHEV setups pretty often lately, I'm wondering about $SUBJ. What is it good for? Is it just for situation when main Data storage domain goes down? If so, I'll probably file a RFE to be able to get the domain from Unattached to Active state and vice versa via single click as having to wait half minute before I can do a successive click is quite a big annoyance.

Re: [Engine-devel] qemu machine type / datacenter machine version
by Andrew Cathrow 08 Apr '12

08 Apr '12

It is only configured in the database today. A good short term solution would be exposing this in the engine-config tool to save users having to hack the database, and potentially set this during setup. But long term we need to incorporate the notion of per VM config versions, right now we take the config version from the cluster, which isn't the best approach. We need to merge the two concepts - host/cluster capabilities and VM config version.

[Engine-devel] VDSM REST API
by Adam Litke 06 Apr '12

06 Apr '12

Hi all, At the oVirt Workshop in Beijing I learned about how the ovirt-shell dynamically discovers: the collections, resource schemas, and allowed actions based on an RSDL file and API xsd schema. I am working on a REST API for vdsm and would like to make my API compatible with the ovirt-engine api such that the same ovirt-shell program could work with either the engine api or the vdsm api. There are many differences between ovirt-engine and vdsm (namely that one is implemented in Java and the other in Python). I think the easiest way to test whether this is possible is to try and create a new, minimalist REST service with python Cherrypy. Such a service would have a root URL with no collections or actions. From my understanding I will need to write the following files: /api - A basic XML representation of the API root resource /api?schema - An xsd that describes the simple API /api?rsdl - An rsdl (XML file) that describes the available links for /api, I want to start with something dead-simple: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <api> <messages> <message id='foo' href='bar'> Hello from vdsm! </message> </messages> </api> Once I can use ovirt-shell to list messages and show messages I will be happy to build on it. Can anyone help me figure out the minimal xsd and rsdl that would be needed for such an API to be consumable by ovirt-shell?

[Engine-devel] Storage Domain level 3

Hi all, this is about supporting of I18N (https://bugzilla.redhat.com/show_bug.cgi?id=786448) The VDSM already supports it, but only for storage domain level 3. >From Dan Kenigsberg's mail: "I hope ovirt-Engine learns to do storage domain upgrade, and uses level 3, so that this feature can be used." So, how is it with supporting this in the engine? Thank you, Tomas
