[Users] Opaque oVirt/RHEV/Proxmox client and source code released
by i iordanov 07 Feb '14

07 Feb '14

Hello! Apologies for the cross-post. I've released Opaque into production on Google Play: https://play.google.com/store/apps/details?id=com.undatech.opaque and on Blackberry World for devices running Blackberry OS 10.2.1 or newer: http://appworld.blackberry.com/webstore/content/46004889 The source code is now part of the renamed (formerly bVNC) repository: https://github.com/iiordanov/remote-desktop-clients The old name of the repository links to the new one. I didn't think it's a good idea to keep calling it bVNC given that it already contains code to build 4 different remote desktop clients. If you are an oVirt or RHEV admin, please ensure that Opaque works in your environment before recommending it to your users. Please start by reading the KNOWN ISSUES section in the description of the application. Thanks for all the feedback I received from the beta test community! I will still be releasing new features to be beta-tested before pushing them to production. Sincerely, iordan -- The conscious mind has only one thread of execution.

[Users] VNC Console
by ml ml 07 Feb '14

07 Feb '14

Hello List, i am running ovirt 3.3.3-2.el6. It looks really cool and nice. However, the VNC Console drives me Crazy. I can seem to get a proper Key Mapping. My VNC Keyboard Layout is set to "en-us" and i am booting a live cd, also with en-us key mapping. However the keys such as / or = are not working and its driving me carzy that i am failing on this simple task. Can anyone help? What Client do you use in Mac and Windows? Is there anything else i need to take care of? Thanks, Mario

Hi Dave (and everyone else who responded), Thank you for your explanations. It was the objectiveness I was looking for, even though you work for Red Hat :-) At least the benefits of RHEV are way more clear to me now, which is what I needed. The choice is still a tough one, expecially since the oVirt users mailing list is one of most helpful ones I know. Thanks again, Martijn.

Hi René, Sorry for top-posting, but I just wanted to say that this was a really helpful answer, and it actually made me rethink yesterday's decision:-). Thank you very much. Cheers, Martijn.

[Users] SPICE behind NAT
by Alan Murrell 07 Feb '14

07 Feb '14

I have setup a test All-In-One install but it is behind a Linux NAT firewall (IPTables). I have been reading about Spice-Proxy and know the basics of setting it up (install squid, configure the ovirt engine SpiceProxyDefault), however I just wanted to know how I would do this in a NAT situation? Would I install Squid on the firewall? When I configure SpiceProxyDefault on the ovirt-engine, I set it to use the internal IP of the firewall/Squid? Anything else I would possibly need to do? -Alan

[Users] Constant lopping log of task activity
by Matt Warren 07 Feb '14

07 Feb '14

I'm seeing a constant loop of task issues in the vdsm.log Host is a CentOS 6.5 server otherwise setup as a db lab server. Engine is a CentOS 6.5 vm running on vmware esx host. The host has local storage only. Not sure if related, but I've been trying to attach a Win2k8-hosted NFS share for ISO's and failing. I can manually mount it just fine from the host os, but the ovirt-engine complains of privileges errors. I also had trouble getting the host recognized in ovirt dues to a messed up sudoers file. With that sorted, it added and report fine. Any troubleshooting tips? -------------------------------------------- Thread-84::DEBUG::2014-02-02 16:08:55,459::BindingXMLRPC::167::vds::(wrapper) client [10.1.9.11] Thread-84::DEBUG::2014-02-02 16:08:55,459::task::579::TaskManager.Task::(_updateState) Task=`cc9c6dac-ed6e-4cc9-a3e4-b741c5137caf`::moving from state init -> state preparing Thread-84::INFO::2014-02-02 16:08:55,460::logUtils::44::dispatcher::(wrapper) Run and protect: getSpmStatus(spUUID='b780d909-b6a0-4a38-82e2-3d7fd3a2b745', options=None) Thread-84::INFO::2014-02-02 16:08:55,460::logUtils::47::dispatcher::(wrapper) Run and protect: getSpmStatus, Return response: {'spm_st': {'spmId': 1, 'spmStatus': 'SPM', 'spmLver': 1}} Thread-84::DEBUG::2014-02-02 16:08:55,460::task::1168::TaskManager.Task::(prepare) Task=`cc9c6dac-ed6e-4cc9-a3e4-b741c5137caf`::finished: {'spm_st': {'spmId': 1, 'spmStatus': 'SPM', 'spmLver': 1}} Thread-84::DEBUG::2014-02-02 16:08:55,460::task::579::TaskManager.Task::(_updateState) Task=`cc9c6dac-ed6e-4cc9-a3e4-b741c5137caf`::moving from state preparing -> state finished Thread-84::DEBUG::2014-02-02 16:08:55,460::resourceManager::939::ResourceManager.Owner::(releaseAll) Owner.releaseAll requests {} resources {} Thread-84::DEBUG::2014-02-02 16:08:55,461::resourceManager::976::ResourceManager.Owner::(cancelAll) Owner.cancelAll requests {} Thread-84::DEBUG::2014-02-02 16:08:55,461::task::974::TaskManager.Task::(_decref) Task=`cc9c6dac-ed6e-4cc9-a3e4-b741c5137caf`::ref 0 aborting False Thread-85::DEBUG::2014-02-02 16:08:55,470::BindingXMLRPC::167::vds::(wrapper) client [10.1.9.11] Thread-85::DEBUG::2014-02-02 16:08:55,470::task::579::TaskManager.Task::(_updateState) Task=`59aa1ec2-64b9-4c6d-bdb8-66154f73915d`::moving from state init -> state preparing Thread-85::INFO::2014-02-02 16:08:55,470::logUtils::44::dispatcher::(wrapper) Run and protect: getStoragePoolInfo(spUUID='b780d909-b6a0-4a38-82e2-3d7fd3a2b745', options=None) Thread-85::DEBUG::2014-02-02 16:08:55,471::resourceManager::197::ResourceManager.Request::(__init__) ResName=`Storage.b780d909-b6a0-4a38-82e2-3d7fd3a2b745`ReqID=`7bbb6abd-006b- 4b7b-b540-322dfdda7644`::Request was made in '/usr/share/vdsm/storage/hsm.py' line '2553' at 'getStoragePoolInfo' Thread-85::DEBUG::2014-02-02 16:08:55,471::resourceManager::541::ResourceManager::(registerResource) Trying to register resource 'Storage.b780d909-b6a0-4a38-82e2-3d7fd3a2b745' for lock type 'shared' Thread-85::DEBUG::2014-02-02 16:08:55,471::resourceManager::600::ResourceManager::(registerResource) Resource 'Storage.b780d909-b6a0-4a38-82e2-3d7fd3a2b745' is free.

[Users] Will this two node concept scale and work?
by ml ml 06 Feb '14

06 Feb '14

Hello List, my aim is to host multiple VMs which are redundant and are high available. It should also scale well. I think usually people just buy a fat iSCSI Storage and attach this. In my case it should scale well from very small nodes to big ones. Therefore an iSCSI Target will bring a lot of overhead (10GBit Links and two Paths, and really i should have a 2nd Hot Standby SAN, too). This makes scalability very hard. This post is also not meant to be a iscsi discussion. Since oVirt does not support DRBD out of the box i came up with my own concept: http://oi62.tinypic.com/2550xg5.jpg As far as i can tell i have the following advantages: -------------------------------------------------------------------- - i can start with two simple cheap nodes - i could add more disks to my nodes. Maybe even a SSD as a dedicated drbdresource. - i can connect the two nodes directly to each other with bonding or infiniband. i dont need a switch or something between it. Downside: --------------- - i always need two nodes (as a couple) Will this setup work for me. So far i think i will be quite happy with it. Since the DRBD Resources are shared in dual primary mode i am not sure if ovirt can handle it. It is not allowed to write to a vm disk at the same time. The Concept of Linbit ( http://www.linbit.com/en/company/news/333-high-available-virtualization-at-…) seems to much of an overhead with the iSCSI Layer and pacemaker setup. Its just too much for such a simple task. Please tell me that this concept is great and will work and scale well. Otherwise i am also thankful for any hints or critical ideas. Thanks a lot, Mario

Thank you, this is what I thought. It's still a hard decision.
