[Engine-devel] AsyncTaskManager and the irsbroker
by Laszlo Hornyak 24 Oct '12

24 Oct '12

hi, I have just noticed that AsyncTaskManager is - almost all of the public methods are synchronized - and it is singleton - calling to VDS operations (line 291) Therefore this may be a performance bottleneck. Even when you want to create an asynchronous task or query a task's state, you may have to wait till a remote vdsm responds. Would it be ok to remove the synchronization from e.g. the query-like methods? Or the one initiating remote calls? Laszlo

[Engine-devel] Quota in 3.2 - design
by Ofri Masad 23 Oct '12

23 Oct '12

Hi, The new design for quota in 3.2 is available here: http://wiki.ovirt.org/wiki/Features/Design/Quota-3.2 Most of the changes would be in the backend. Feedbacks would be more than welcome. We are trying to make quota more inherent (more framework like) and easier to handle when you create a new command. Other than the design described in the wiki, we thought of two other designs which would help us identify the commands which are dependent on quota: 1. Using annotations - by this approach we would add an annotation to the command class telling us it's a quota consumer and a second annotation to the method returning the consumption parameters. 2. Using just interfaces without the markings in VdcActionType (this is the current implementation) - in this case the implemented interfaces are inherited by extending commands. So if one inherits some command without handling the quota parameters - we get wrong quota consumption and even holes in the quota. again, any feedbacks would be more than welcome. Thanks ahead, Ofri

[Engine-devel] git-review
by Saggi Mizrahi 22 Oct '12

22 Oct '12

I've recently encountered more and more people not using the git-review tool and manually pushing their changes to Gerrit using raw git commands. Even though there is nothing wrong with doing things the hard way. I prefer not using an overly complicated error prone way to interact with Gerrit. Last I checked the version of git-review in Fedora is broken but I suggest using pip anyway as it is always synced with the master branch. Also, please use topics. Either use a BZ# or a topic codename (eg. live_migration, vdsm_api, nfs4_support) so people can skim the review list for topics they might want to review. Be careful, it automatically uses current the branch name (unless you use -t) so if you giving your branches funny names (I know I do) don't forget to manually specify a topic. More information. http://wiki.openstack.org/GerritWorkflow https://github.com/openstack-ci/git-review

[Engine-devel] Strange input from oVirt-engine for create (VM) API
by Adam Litke 22 Oct '12

22 Oct '12

Hi all, Today I was watching the vdsm log as ovirt-engine started a VM and I saw something peculiar with how VM device addresses were specified. Here is a sample of the python dictionary for the VM from vdsm.log (I reformatted it with pprint for readability): {'address': {' bus': '1', ' controller': '0', ' target': '0', ' type': 'drive', 'unit': '0'}, Notice the whitespace in the 'controller', 'target', and 'type' keys. Could someone explain why this is happening? Is it deliberate or a bug? Thanks! -- Adam Litke <agl(a)us.ibm.com> IBM Linux Technology Center

[Engine-devel] Couple of small Feature Requests
by Dead Horse 19 Oct '12

19 Oct '12

Would like to make a couple of small feature requests. 1) Allow for the SPICE or VNC password to be set in the UI by admin's or power users. Benefit: (Assumes spice SSL has been disabled) allows user or admin to set a password for access by a standalone remote session via vncviewer or remote-viewer or the spice html5 implementation which is WIP, or standalone HW thin client - This may also assume that vdsm is running with SSL disabled as well to have had vdsm make the neccesary changes to the qemu spice configuration 2) Display currently configured OR generated password and IP/Port for either VNC or SPICE console of the VM within the PUP and Admin UI Benefit: At the very least a standalone remote client can be used to connect once the password and IP/PORT is known for spice or VNC - Currently VNC will display a dialog that shows the this info but it would be more useful to have it displayed in the UI given proper privilege 3) Display the UUID of a VM in the Admin UI (similar to the how the disks tab breaks down and shows DISK UUID mappings) - Benefit: Easier for administrators to map UUID to VM config file data in the data stores or export domains - DHC

I guess the next time point I'll be hit by this issue is live migration, but not sure about that (I don't remember if libvirt still validates the host name before migration). > > Any idea? > > Thanks, > Simon. > > ----- Original Message ----- > > From: "Mike Burns" <mburns(a)redhat.com> > > To: "node-devel" <node-devel(a)ovirt.org>, "users" <users(a)ovirt.org> > > Sent: Friday, October 5, 2012 6:23:11 PM > > Subject: [Users] oVirt Node 2.5.2 ISO released > > > > The long awaited and much anticipated oVirt Node 2.5.2 ISO is now > > available on ovirt.org.

[Engine-devel] Network related hooks in vdsm
by Igor Lvovsky 18 Oct '12

18 Oct '12

Hi everyone, As you know vdsm has hooks mechanism and we already support dozen of hooks for different needs. Now it's a network's time. We would like to get your comments regarding our proposition for network related hooks. In general we are planning to prepare framework for future support of bunch network related hooks. Some of them already proposed by Itzik Brown [1] and Dan Yasny [2]. Below you can find the additional hooks list that we propose: Note: In the first stage we can implement these hooks without any parameters, just to provide an entry point for simple hooks. Networks manipulation: - before_add_network(conf={}, customProperty={}) - after_add_network(conf={}, customProperty={}) - before_del_network(conf={}, customProperty={}) - after_del_network(conf={}, customProperty={}) - before_edit_network(conf={}, customProperty={}) - after_edit_network(conf={}, customProperty={}) - TBD Bondings manipulations: - before_add_bond(conf={}, customProperty={}) - after_add_bond(conf={}, customProperty={}) - before_del_bond(conf={}, customProperty={}) - after_del_bond(conf={}, customProperty={}) - before_edit_bond(conf={}, customProperty={}) - after_edit_bond(conf={}, customProperty={}) - TBD General purpose: - before_persist_network - after_persist_network Now we just need to figure out the use cases. Your input more than welcome... [1] http://gerrit.ovirt.org/#/c/7224/ - Adding hooks support for NIC hotplug [2] http://gerrit.ovirt.org/#/c/7547/ - Hook: Cisco VM-FEX support Regards, Igor Lvovsky
