[Users] iSCSI discovery not showing all LUNs - oVirt 3.1
by Trey Dockendorf 06 Jul '12

06 Jul '12

I have a Promise M300i iSCSI with 2 LUNs. A 2TB LUN with ID 2260-0001-557c-af0a and a 4TB LUN with ID 22d9-0001-553e-4d6a. What's strange, is the very first time I ran discovery I saw both LUNs. I checked the 2TB LUN and storage failed to add, I don't have logs at this time, but I went back to repeat the process and now only 1 LUN shows in the GUI (see attached image). Also the size it reports is way off. Looking at VDSM logs, I get this output when doing the login to a target {'devList': [ {'vendorID': 'Promise', 'capacity': '2188028149760', 'fwrev': '0227', 'partitioned': False, 'vgUUID': 'AZ1iMt-gzBD-2uug-xTih-1z0b-PqPy-xSP0A4', 'pathlist': [ { 'initiatorname': 'default', 'connection': '192.168.203.100', 'iqn': 'iqn.1994-12.com.promise.xxx', 'portal': '1', 'password': '******', 'port': '3260' } ], 'logicalblocksize': '512', 'pathstatus': [ { 'physdev': 'sde', 'type': 'iSCSI', 'state': 'active', 'lun': '0' } ], 'devtype': 'iSCSI', 'physicalblocksize': '512', 'pvUUID': 'v2N3ok-wrki-OQQn-1XFL-w69n-8wAF-rmCFWt', 'serial': 'SPromise_VTrak_M300i_000000000000000000000000F08989F89FFF6C42', 'GUID': '222600001557caf0a', 'productID': 'VTrak M300i' }, { 'vendorID': 'Promise', 'capacity': '20246190096384', 'fwrev': '0227', 'partitioned': False, 'vgUUID': '', 'pathlist': [ { 'initiatorname': 'default', 'connection': '192.168.203.100', 'iqn': 'iqn.1994-12.com.promise.xxx', 'portal': '1', 'password': '******', 'port': '3260' } ], 'logicalblocksize': '2048', 'pathstatus': [ { 'physdev': 'sdf', 'type': 'iSCSI', 'state': 'active', 'lun': '1' } ], 'devtype': 'iSCSI', 'physicalblocksize': '2048', 'pvUUID': '', 'serial': 'SPromise_VTrak_M300i_000000000000000000000000DA3FF8D8099662D7', 'GUID': '222d90001553e4d6a', 'productID': 'VTrak M300i' } ] } In that output both LUNs are seen. I couldn't tell from the code what format the "capacity" is in, but now the interface shows only the LUN with the "4d6a" GUID as being 18TB. I've attached the VDSM Logs from the point of selecting my datacenter to after clicking "Login". Any suggestions? node - vdsm-4.10.0-2.el6.x86_64 Thanks - Trey

[Users] What is it going to take to get EL6 builds?
by Robert Middleswarth 06 Jul '12

06 Jul '12

I know there are a few things that don't work under oVirt on EL6 but there are unofficial builds out there and they seem to work pretty well. What is the major stopper from getting EL6 builds? Is it just a mater of getting patches submitted for building the spec files? Is there a need for EL 6 based slaves? Is there a concern about the features that don't work like Live Migration? I guess a good starting point is to build a todo list of what has to be done. Thanks Robert

Hi, Is it possible to create some sort of virtual desktop for teaching/vpn purposes where we can use ldap for login credential for every virtual desktop? -- Regards, Umarzuki Mochlis http://debmal.my

[Users] Getting some 3.1 screencasts
by Dave Neary 05 Jul '12

05 Jul '12

Hi everyone, At the team meeting today Jason Clift suggested that it would be great to have some screencasts for the 3.1 release. I agree. So let's see if we can make some! To spread the load as much as possible, here's what I propose: 1. We come up with a set (5-10) of demo stories we want to tell in the wiki. These should contain: * The feature we want to demo * The "before recording" set-up that needs to be done * The steps to demo the feature * A quick script that someone can follow to explain what they're doing. I'd like a few of these scripts to be for existing oVirt features (say, migrating a VM to a different node) and a few to be for features which are new in 3.1 (see the release notes at http://ovirt.org/wiki/Release_Notes_Draft for details there, we should pick one or two nice visible features like all-in-one install). 2. From the scripts, we record the demos as .ogv using RecordMyDesktop or GNOME Shell's built-in desktop recording 3. Finally, we do voice-overs to add a sound track to the demo (and if we have any skilled sound engineers, some tasteful CC licenced background music would be great!) This way, we've broken down the creation of 5 screencasts into 15 different byte-sized tasks - script, video, voiceover - none of which should take someone more that 20 minutes or half an hour - which hopefully will make it easier to get them done together. How does this plan sound? If it sounds good, which features do you think we should screencast as top priority? Thanks! Dave. -- Dave Neary Community Action and Impact Open Source and Standards Team, Red Hat Phone: +33 9 50 71 55 62

[Users] What are you looking for from oVirt?
by Dave Neary 05 Jul '12

05 Jul '12

Hi everyone, That is a grand subject for my first "proper" email to the Users list, and it definitely needs some context! So let me introduce myself. My name is Dave Neary, and I recently started working for a group which is being formed inside Red Hat called OSAS (open source and standards). The role of my group is to help make any open source projects that Red Hat works in successful, and I would really like to help take oVirt to the next level in terms of adoption and contribution. One of the things I'm still figuring out is what the natural audience for oVirt is, and what you all like about oVirt, and would like to see improved. Based on that, I would like to propose areas we as a community can concentrate on related to the product, the website, and our marketing and promotion, but the first step is still to get a better idea what the target audience for oVirt is, and should be. So - how are you using oVirt? Why did you choose it over alternatives? What do you like about it? and what would you like to see change, whether that is in terms of technical, process, or marketing changes? I'm here to help, but to do so I need your help first! Please feel free to reply to me on-list (if you'd like to start discussion) or off-list (if you'd like your feedback to be more discrete). Any feedback at all will be helpful. Thank you very much - I look forward to hearing from as many of you as possible. Regards, Dave. PS. I'm still figuring out proper mailing list etiquette for this project - I've added board@ and arch@ to CC since I expect our work to have project-wide consequences, but it's more to keep people informed at this point. Please let me know off-list if I'm doing something I shouldn't! -- Dave Neary Community Action and Impact Open Source and Standards Team, Red Hat Phone: +33 9 50 71 55 62

Hi everyone, I created a Desktop VM1 with all default settings and added a 2G Disk to the VM1 in WebAdmin. But when I run the vm, it returns failure with the follow error message in WebAdmin. "VM VM1 is down. Exit message: Unable to create cgroup for VM1" My DateCenter contains one host(with OS is CentOS 6, VDSM version is 4.9.6 and libvirt version is 0.9.4) and one NFS domain. And The cgroup Directory have already exits on the host. But why cannot I run the VM1? There are some error message in VDSM log -------- File "/usr/lib64/python2.6/site-packages/libvirt.py", line 2087, in createXML if ret is None: raise libvirtError('virDomainCreateXML() failed', conn=self) libvirtError: Unable to create cgroup for VM1: No such file or directory ---------- There are some error message in libvirt log --------- error : virNetClientProgramDispatchError:170 : Unable to create cgroup for VM1: No such file or directory" --------- There are log files in attachment Best wishes, Xuejie Chen
