[Engine-devel] RFC: Writeup on VDSM-libstoragemgmt integration
by Deepak C Shetty 26 Jun '12

26 Jun '12

Hello All, I have a draft write-up on the VDSM-libstoragemgmt integration. I wanted to run this thru' the mailing list(s) to help tune and crystallize it, before putting it on the ovirt wiki. I have run this once thru Ayal and Tony, so have some of their comments incorporated. I still have few doubts/questions, which I have posted below with lines ending with '?' Comments / Suggestions are welcome & appreciated. thanx, deepak [Ccing engine-devel and libstoragemgmt lists as this stuff is relevant to them too] -------------------------------------------------------------------------------------------------------------- 1) Background: VDSM provides high level API for node virtualization management. It acts in response to the requests sent by oVirt Engine, which uses VDSM to do all node virtualization related tasks, including but not limited to storage management. libstoragemgmt aims to provide vendor agnostic API for managing external storage array. It should help system administrators utilizing open source solutions have a way to programmatically manage their storage hardware in a vendor neutral way. It also aims to facilitate management automation, ease of use and take advantage of storage vendor supported features which improve storage performance and space utilization. Home Page: http://sourceforge.net/apps/trac/libstoragemgmt/ libstoragemgmt (LSM) today supports C and python plugins for talking to external storage array using SMI-S as well as native interfaces (eg: netapp plugin ) Plan is to grow the SMI-S interface as needed over time and add more vendor specific plugins for exploiting features not possible via SMI-S or have better alternatives than using SMI-S. For eg: Many of the copy offload features require to use vendor specific commands, which justifies the need for a vendor specific plugin. 2) Goals: 2a) Ability to plugin external storage array into oVirt/VDSM virtualization stack, in a vendor neutral way. 2b) Ability to list features/capabilities and other statistical info of the array 2c) Ability to utilize the storage array offload capabilities from oVirt/VDSM. 3) Details: LSM will sit as a new repository engine in VDSM. VDSM Repository Engine WIP @ http://gerrit.ovirt.org/#change,192 Current plan is to have LSM co-exist with VDSM on the virtualization nodes. *Note : 'storage' used below is generic. It can be a file/nfs-export for NAS targets and LUN/logical-drive for SAN targets. VDSM can use LSM and do the following... - Provision storage - Consume storage 3.1) Provisioning Storage using LSM Typically this will be done by a Storage administrator. oVirt/VDSM should provide storage admin the - ability to list the different storage arrays along with their types (NAS/SAN), capabilities, free/used space. - ability to provision storage using any of the array capabilities (eg: thin provisioned lun or new NFS export ) - ability to manage the provisioned storage (eg: resize/delete storage) Once the storage is provisioned by the storage admin, VDSM will have to refresh the host(s) for them to be able to see the newly provisioned storage. 3.1.1) Potential flows: Mgmt -> vdsm -> lsm: create LUN + LUN Mapping / Zoning / whatever is needed to make LUN available to list of hosts passed by mgmt Mgmt -> vdsm: getDeviceList (refreshes host and gets list of devices) Repeat above for all relevant hosts (depending on list passed earlier, mostly relevant when extending an existing VG) Mgmt -> use LUN in normal flows. 3.1.2) How oVirt Engine will know which LSM to use ? Normally the way this works today is that user can choose the host to use (default today is SPM), however there are a few flows where mgmt will know which host to use: 1. extend storage domain (add LUN to existing VG) - Use SPM and make sure *all* hosts that need access to this SD can see the new LUN 2. attach new LUN to a VM which is pinned to a specific host - use this host 3. attach new LUN to a VM which is not pinned - use a host from the cluster the VM belongs to and make sure all nodes in cluster can see the new LUN Flows for which there is no clear candidate (Maybe we can use the SPM host itself which is the default ?) 1. create a new disk without attaching it to any VM 2. create a LUN for a new storage domain 3.2) Consuming storage using LSM Typically this will be done by a virtualization administrator oVirt/VDSM should allow virtualization admin to - Create a new storage domain using the storage on the array. - Be able to specify whether VDSM should use the storage offload capability (default) or override it to use its own internal logic. 4) VDSM potential changes: 4.1) How to represent a VM disk, 1 LUN = 1 VMdisk or 1 LV = 1 VMdisk ? which bring another question...1 array == 1 storage domain OR 1 LUN/nfs-export on the array == 1 storage domain ? Pros & Cons of each... 1 array == 1 storage domain - Each new vmdisk (aka volume) will be a new lun/file on the array. - Easier to exploit offload capabilities, as they are available at the LUN/File granularity - Will there be any issues where there will be too many LUNs/Files ... any maxluns limit on linux hosts that we might hit ? -- VDSM has been tested with 1K LUNs and it worked fine - ayal - Storage array limitations on the number of LUNs can be a downside here. - Would it be ok to share the array for hosting another storage domain if need be ? -- Provided the existing domain is not utilising all of the free space -- We can create new LUNs and hand it over to anyone needed ? -- Changes needed in VDSM to work with raw LUNs, today it only has support for consuming LUNs via VG/LV. 1 LUN/nfs-export on the array == 1 storage domain - How to represent a new vmdisk (aka vdsm volume) if its a LUN provisioned using SAN target ? -- Will it be VG/LV as is done today for block domains ? -- If yes, then it will be difficult to exploit offload capabilities, as they are at LUN level, not at LV level. - Each new vmdisk will be a new file on the nfs-export, assuming offload capability is available at the file level, so this should work for NAS targets ? - Can use the storage array for hosting multiple storage domains. -- Provision one more LUN and use it for another storage domain if need be. - VDSM already supports this today, as part of block storage domains for LUNs case. Note that we will allow user to do either one of the two options above, depending on need. 4.2) Storage domain metadata will also include the features/capabilities of the storage array as reported by LSM. - Capabilities (taken via LSM) will be stored in the domain metadata during storage domain create flow. - Need changes in oVirt engine as well ( see 'oVirt Engine potential changes' section below ) 4.3) VDSM to poll LSM for array capabilities on a regular basis ? Per ayal: - If we have a 'storage array' entity in oVirt Engine (see 'oVirt Engine potential changes' section below ) then we can have a 'refresh capabilities' button/verb. - We can periodically query the storage array. - Query LSM before running operations (sounds redundant to me, but if it's cheap enough it could be simplest). Probably need a combination of 1+2 (query at very low frequency - 1/hour or 1/day + refresh button) 5) oVirt Engine potential changes - as described by ayal : - We will either need a new 'storage array' entity in engine to keep credentials, or, in case of storage array as storage domain, just keep this info as part of the domain at engine level. - Have a 'storage array' entity in oVirt Engine to support 'refresh capabilities' as a button/verb. - When user during storage provisioning, selects a LUN exported from a storage array (via LSM), the oVirt Engine would know from then onwards that this LUN is being served via LSM. It would then be able to query the capabilities of the LUN and show it to the virt admin during storage consumption flow. 6) Potential flows: - Create snapshot flow -- VDSM will check the snapshot offload capability in the domain metadata -- If available, and override is not configured, it will use LSM to offload LUN/File snapshot -- If override is configured or capability is not available, it will use its internal logic to create snapshot (qcow2). - Copy/Clone vmdisk flow -- VDSM will check the copy offload capability in the domain metadata -- If available, and override is not configured, it will use LSM to offload LUN/File copy -- If override is configured or capability is not available, it will use its internal logic to create snapshot (eg: dd cmd in case of LUN). 7) LSM potential changes: - list features/capabilities of the array. Eg: copy offload, thin prov. etc. - list containers (aka pools) (present in LSM today) - Ability to list different types of arrays being managed, their capabilities and used/free space - Ability to create/list/delete/resize volumes ( LUN or exports, available in LSM as of today) - Get monitoring info with object (LUN/snapshot/volume) as optional parameter for specific info. eg: container/pool free/used space, raid type etc. Need to make sure above info is listed in a coherent way across arrays (number of LUNs, raid type used? free/total per container/pool, per LUN?. Also need I/O statistics wherever possible.

This is a multi-part message in MIME format. --------------060000080308030607050901 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Hi all, Now I'm using the code generation suites of ovirt-engine-sdk, I find it is very troublesome. IMO, we can simplify the process. And I want to engaged in it. there are two tools parse the api.xsd and generate the params.py code. They are generateds_gui.py and generateDS.py. but there still some code can not be generate by these tools. now we should add these codes manually. the not NOT_GENERATED codes are as follow in the current params.py code: 1. import python module 2. a new attribute of GeneratedsSuper class 3. modify the get_root_tag function. 4. modify the parseString function to shut up the stdout. 5. _rootClassMap 6 . _elementToClassMap 7. findRootClass And I have two ideas about the code generation. For we should not modify the generateDS.py tools. But we can improve it. I think the 1, 2, 3, 7, can be hard-code, and 4, 5 and 6 can be configured. So I want to add an configure file to tell how to add the extra code that are not generated by generateDS.py tools. And new python program, as extension of generateDS.py to read the configure file and generate these codes. Or without the configure file, just make the new python program that supports an interactive commands. --------------060000080308030607050901 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit <html> <head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000"> Hi all, Now I'm using the code generation suites of ovirt-engine-sdk, I find it is very troublesome.

[Engine-devel] Maven 3 here we come!
by Doron Fediuck 03 Jun '12

03 Jun '12

Hi all, As discussed last month[1], we had to deal with some issues which turned out to be a Maven bug. Thanks to Juan and Asaf's work, our current sources now build properly using Maven 3. So you're all invited to migrate into Maven 3. Other than upgrading your local maven package no other action is needed. For now, Maven 2 will also work for you, but I expect in the future we'd like to make use of some advanced features, so migration to 3 is recommended. Talking about advanced features, an interesting challenge is feedback on parallel builds [2]. So whoever wants to try it out and report if it improves run time without breaking anything, will be appreciated. Happy migration! [1]http://lists.ovirt.org/pipermail/arch/2012-April/000490.html [2] https://cwiki.apache.org/MAVEN/parallel-builds-in-maven-3.html -- /d "Email returned to sender -- insufficient voltage."

[Engine-devel] Build and run with Fedora 17 jboss-as packages
by Juan Hernandez 31 May '12

31 May '12

Hello, The changes required to build and run the engine using the jboss-as packages in Fedora 17 have been recently merged: http://gerrit.ovirt.org/4416 This means that from now on in order to install the RPMs you will need a Fedora 17 machine. In addition this also changes how the application server is used. We have been running the engine as an application deployed to the default instance of the application server. Starting now the engine will run a private instance of the application server owned by the user ovirt ovirt and managed by systemd, so please remember that you don't longer need/should start the jboss-as service, but the ovirt-engine systemd service: systemctl start ovirt-engine.service systemctl stop ovirt-engine.service The locations of the files/directories used by this private instance of the application server are also different: 1. You are probably familiar with the standalone.xml file. This is no longer used, we use the /etc/ovirt-engine/engine-service.xml instead. 2. The location of the engine.ear file is still the same (/usr/share/ovirt-engine/engine.ear), but the deployment marker file engine.ear.dodeploy is not created in the same directory. Instead of that a symlink to the engine.ear file is created in /var/lib/ovirt-engine/deployments directory and the engine.ear.dodeploy file is created there by the start/stop script. 3. Locations of log files are also slightly different. The main log file is still /var/log/ovirt-engine/engine.log, but the server.log file is no longer in the jboss-as directory, but in /var/log/ovirt-engine as well. In addition there is a /var/log/ovirt-engine/console.log file that stores the standard and error output of the engine. There are other changes, but probably less relevant to most of you. I made many tests, but I am sure that issues will appear, so please keep an eye on this and let me know of any issues you may encounter. Regards, Juan Hernandez

[Engine-devel] Shared Memory
by Amador Pahim 31 May '12

31 May '12

Hello, Not sure if it was already discussed, but I'd like to talk about oVirt "Shared Memory". Webadmin has the Shared Memory percent information in host general tab [1]. Initially, I thought that Shared Memory was the KSM de-duplication results. But comparing with my KSM stats, it does not make sense. My env: 3,5 GB virt-host. 6 identical VMs running with 1GB RAM each. Webadmin host details: Memory Sharing: Active Shared Memory: 0% KSM - How many shared pages are being used: $ cat /sys/kernel/mm/ksm/pages_sharing 109056 KSM - How many more sites are sharing them i.e. how much saved $ cat /sys/kernel/mm/ksm/pages_sharing 560128 Converting to Mbytes: $ echo $(( (109056 * $(getconf PAGE_SIZE)) / (1024 * 1024) )) 426 $ echo $(( ( 560128 * $(getconf PAGE_SIZE)) / (1024 * 1024) )) 2188 With those KSM results, I could expect something but 0 in "Shared Memory". Tracing the origin of "Shared Memory" in oVirt code, I realized it's coming from memShared value (from getVdsStats vdsm command), which is provided in Mbytes: $ vdsClient -s 192.168.10.250 getVdsStats | grep memShared memShared = 9 Finding memShared function in vdsm, we have: $VDSM_ROOT/vdsm/API.py ... stats['memShared'] = self._memShared() / Mbytes ... def _memShared(self): """ Return an approximation of memory shared by VMs thanks to KSM. """ shared = 0 for v in self._cif.vmContainer.values(): if v.conf['pid'] == '0': continue try: statmfile = file('/proc/' + v.conf['pid'] + '/statm') shared += int(statmfile.read().split()[2]) * PAGE_SIZE_BYTES except: pass return shared ... memShared is calculated adding the shared pages value (3rd field) from /proc/<VM_PID>/statm file from all running VMs, converting to bytes through PAGE_SIZE value and transforming to Mbytes at the end. This field in statm file currently is (it changed along kernel history) the count of pages instantiated in the process address space which are shared with a file, including executable, library or shared memory. Despite vdsm code comment, KSM shared pages are not accounted here. KSM works de-duplicating and sharing memory pages without process awareness. Engine is calculating the percent considering total physical memory - memSize value from getVdsCapabilities vdsm command: $ vdsClient -s 192.168.10.250 getVdsCapabilities | grep memSize memSize = 3574 Calculating the percent: $ echo "scale=2; 9 * 100 / 3574" | bc .25 So, we have arround 0,25%, rounded to 0%. "Shared Memory" is coherent, but not reflecting the real page deduplication benefits. And unnoticed administrators - me included - are led to think that Shared Memory is related with KSM results. IMO, memShared is not providing any representative information. On the other hand, the missing KSM results are really important to oVirt administrators, providing information about how much memory they are over committed by, for capacity management, and how much money oVirt is saving in memory. In order to offer those KSM stats to engine, I sent a patch [2] (waiting approval) adding "ksmShared" and "ksmSharing" values to vdsm getVdsStats command in a standard way, with key names that fits with existing KSM ones (ksmCpu, ksmPages and ksmState). Before patch: $ vdsClient -s 192.168.10.250 getVdsStats | grep ksm ksmCpu = 1 -> the ksmd process cpu load ksmPages = 664 -> pages to scan before ksmd goes to sleep ksmState = True -> is ksm running? With the patch: $ vdsClient -s 192.168.10.250 getVdsStats | grep ksm ksmCpu = 1 ksmPages = 664 ksmShared = 426 -> how many Mbytes of memory are being shared ksmSharing = 2188 -> how many more sites are sharing them i.e. how much Mbytes are being saved ksmState = True Finally my questions: 1 - Is sharedMem value (from /proc/PID/statm) that significant to be kept in host details? If yes, why? 2 - What about - and how (%, Mb, ...) - to add the vdsm new ksmShared and ksmSharing stats in host details? Sorry about my long history. I look forward to hearing your comments. All the best, -- Pahim [1] - http://www.pahim.org/wp-content/uploads/2012/05/Screenshot-oVirt-Enterprise… [2] - http://gerrit.ovirt.org/4755

[Engine-devel] Adding atomic restore snapshot command at backend
by Michael Pasternak 31 May '12

31 May '12

Currently 'restore snapshot' done in two steps on a client side: 1. TryBackToAllSnapshotsOfVm 2. RestoreAllSnapshots This implementation creates race condition on 1 and therefore unstable & bug prone, i suggested refactoring 2 to include 1 as single atomic operation at backend. -- Michael Pasternak RedHat, ENG-Virtualization R&D

[Engine-devel] Using 3.1.0 instead of 3.1.0-0001 for next release?
by Juan Hernandez 30 May '12

30 May '12

Hello, I think we have the opportunity now to clean the version number and use 3.1.0 instead of 3.1.0-0001 for the next release. I submitted the corresponding change to gerrit for review: http://gerrit.ovirt.org/4914 As far as I can tell there are no issues introduced by this change and it allows a cleaner versioning schema for the RPM packages. Please let me now if you foresee any issue. Regards, Juan Hernandez

by Doron Fediuck 30 May '12

30 May '12

Hi All, In the following wiki, there's a design for enabling the balloon device, which is currently disabled in engine setups. Other than enabling the device, this is also a step forward in the path to vdsm and MoM sub-project integration. More details can be found here: http://www.ovirt.org/wiki/Features/Design/memory-balloon P.S. UI mockups should be updated soon. -- /d “Funny,” he intoned funereally, “how just when you think life can't possibly get any worse it suddenly does.” --Douglas Adams, The Hitchhiker's Guide to the Galaxy

[Engine-devel] Question about host compatibility version
by Ashok Vemuri 29 May '12

29 May '12

Hello, I have a newbie question regarding host/cluster compatibility versions. I hope someone could clarify this for me. We have an old lab setup in which we were managing KVM hostnodes using RHEV Manager (version 2.2.4.51796) . We are now trying to upgrade to the latest version of oVirt Engine (version 3.1.0_0001-1.8.el6). Now, when I add the old KVM node to oVirt Engine, I am getting following error message: Host's Compatibility Version doesn't match the Cluster's Compatibility Version Can someone tell me if oVirt Engine is backward-compatible with older hostnodes? Or do I need to upgrade one or more components (such as VDSM) on the hostnode to be compatible with new engine? Here is the version information from the hostnode I'm trying to add: OS : RHEV Hypervisor - 5.6 - 9.3.el5_6 Kernel : 2.6.18 - 238.5.1.el5 KVM : 83 - 224.el5 VDSM : 2.2.63.23 SPICE : 0.3.0 - 54.el5_5.2 Thanks, Ashok

by Yair Zaslavsky 29 May '12

29 May '12

Hi, After seeing an email regarding api/capabilities and looking at the code, and dealing regardless of that with VDSM versions - I have a question - is it interesting for us to display the list of supported VDSM versions under api/capabilities? Kind regards, Yair

[Engine-devel] REST-API: Exposing correlation-ID
by Ori Liel 29 May '12

29 May '12

Correlation-ID feature allows 'tagging' a call to a Backend command with a String ID, and this ID will be appended to all log messages that result from this command. http://www.ovirt.org/wiki/Features/TaskManagerDetailed In REST-API, we would like to enable the user to pass a correlation-ID when he activates actions. I have two questions: 1) what's the name you'd give this parameter? job-id? batch-id? flow-id? command-id? correlation-id??? 2) I've already implemented this as a url parameter. Are there objections? The only viable alternative I see is as an http header, which doesn't feel right. It's not an option to pass it in the XML body, because sometimes there is no body, for example, in DELETE commands. Thanks Ori.

25 May '12

Hi, I need a reasonable test suites to test VDSM APIs. I know most of tests are done from the engine side manually. But I think we need a reasonable test suites to define the typical workflows of engine usage calling into VDSM APIs and make sure all the functions are doing well. As engine publics REST-APIs, an automated test suites can be created on top of the REST-APs without much difficult. Any other comments about this idea? -- Shu Ming<shuming(a)linux.vnet.ibm.com> IBM China Systems and Technology Laboratory

Then I do the following on the host (running vdsm): #brctl addbr mynetwork #brctl addif mynetwork eth3 The refresh rate as indicated by ovirt-engine GUI is 5 seconds. I don't see that the network is attached to the interface until I manually = restart vdsm. Any suggestion?

[Engine-devel] CPU Pinning @engine
by Doron Fediuck 24 May '12

Hi All, Currently the VDSM has a CPU pinning hook. We'd like to add better support of it into the engine itself. Here's a design draft to cover it: http://www.ovirt.org/wiki/Features/Design/cpu-pinning Please review and comment if needed. Thanks! -- /d Never say "OOPS!" always say "Ah, Interesting!"

[Engine-devel] restapi: New params for import VM/Template
by Gilad Chaplik 23 May '12

23 May '12

Hi All, I am adding the ability to import a VM or a Template to a storage-domain, when this VM or Template already exists in the destination storage domain. Until now, Backend failed this. Now I want to enable the user to specify that he wishes this VM/Template will be created again by a different name, i.e - cloned. [feature page: http://www.ovirt.org/wiki/Features/ImportMoreThanOnce] I plan to achieve this using a new parameter, but I want to reach an agreement about this parameter's name. I thought simply to call it "clone". Another thing that I'll do in the patch-set is add the currently-missing ability to specify whether the snapshots of the VM, which is being imported, will be collapsed into a single snapshot (we have this ability in GUI). I am also deliberating about the name of this parameter. I thought about "collapse_snapshots" (same as in GUI). Does anyone think "clone" and "collapse_snapshots" are inappropriate and has better suggestions? Thanks, Gilad
