inconsistency in json api vs xml/other apis
by Sven Kieske 05 May '14

05 May '14

Hi, there's an inconsistent use of plural vs singular form regarding the "vm" collection in the apis. in json you got a collection named "vm" which contains a list of vms. in xml and via gui you got a collection "vms" which contains a list of vms. I just stumbled upon it, as I used json api already in 3.3.3. and didn't had time to test 3.4 until now. the upgrade itself went very well, but know I have to deal with this api change and the other entity renamings done in json api. what would make this less painful would be an consistent way of getting the ovirt-version via api, so I could easily split my codepath by first querying the api version. unfortunately also this one got changed in json so I'll need to call for every version that might be there. I understand that part of this problem comes from using json when it was not "official supported", but at least this inconsistence use in different apis makes not really much sense to me. should I file a BZ for this? -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

RHEVM 3.2 ReST API VM memory used statistic
by Vikas Kokare 05 May '14

05 May '14

The "memory.used" statistic on a virtual machine is returning a negative value , ie. <statistic href="/api/vms/260f8508-2bea-4202-9b93-f8f0dcddc334/statistics/b7499508-c1c3-32f0-8174-c1783e57bb08" id="b7499508-c1c3-32f0-8174-c1783e57bb08"><name>memory.used</name><description>Memory used (agent)</description><values type="INTEGER"><value><datum>*-2061584303*</datum></value></values><type>GAUGE</type><unit>BYTES</unit><vm href="/api/vms/260f8508-2bea-4202-9b93-f8f0dcddc334" id="260f8508-2bea-4202-9b93-f8f0dcddc334"/></statistic> by the RHEVM 3.2 ReST API. while, in the Web Administration Console, memory consumption for the same VM, shows a positive percentage value. Is this an issue with the ReST API?

I believe that the motivation for the current packaging was that - yajsonrpc is not strictly vdsm-related. It is a candidate for a spin-off - jsonrpc is sever-side only - api might be needed by clients, too. But I hope we'd have reasonable inspection to avoid this need. As long as vdsm can work without jsonrpc, I'd rather that it does not require the package. When we move away of xmlrpc, we could drop the xmlrpc requirement, too. Dan.

Saggi, are you thinking about something similar to fence_sanlockd http://linux.die.net/man/8/fence_sanlockd and its client fence_sanlock? Using them, instead of reimplementing parts of them within Vdsm, seem reasonable in first glance. However http://www.ovirt.org/Features/Sanlock_Fencing#Why_not_use_fence_sanlockd.3F claim that it wastes 2G of storage and requires explicit master domain upgrade. Nir, could you explain why so much space is required by sanlockd?

[Features] Special Request for Feature Page Cleanup Projecy
by Brian Proffitt 01 May '14

01 May '14

All: It has been requested that we add date/timestamps to the Features pages in order to highlight the age of each page and assist users in determining how fresh information is. After investigating various options to do this within the database or using automated code, it seems that the old-fashioned manual way is still the best option. This is because an automated solution would only insert the needed strings, but not the actual data that pertains to that feature. To divide this work among the community, I have made an inventory of all of the features pages in the oVirt.org site as of 3/30/14, located at http://bit.ly/1iA1HQ3. If everyone can take a look at this sheet (check the tabs on the bottom, too) and find the pages they created or for which they are responsible, the following steps should be taken for pages that are marked "Yes" in "Needs Datestamp": 1. Add the following line to the top of each page, under the first heading: {{Feature|name=[Name of Feature]}|modules=[Node(s) of feature]|version=[oVirt version number]|status=Released}} 2. On the Feature page spreadsheet on Google Docs, change the "Yes" in "Needs Datestamp" to "No." This new Feature template string will add the time and date information to the page automatically. If, along the way, you find features that have been deprecated, or feature pages that are duplicates, these pages should be cleaned up as well. Ideally, this should not take too much time for each individual, and the effort will be a big step towards documentation consistency on the oVirt site. If you have any questions/concerns, send them my way.

Remove bad tag in your local mom git repos
by Adam Litke 01 May '14

01 May '14

Hi all, Recently it was discovered that the MOM repo git://gerrit.ovirt.org/mom had a bogus 'HEAD' tag. This is dangerous for obvious reasons. We have removed the tag from the server but you may still have it present in your local repository. To remove it just issue the following command from inside your mom source tree: git tag -d HEAD Please let me know if you experience any further issues. -- Adam Litke
