Re: [ovirt-devel] [node-devel] Node Design ideas - And what you would like to see in or how you would like to see Node
by Doron Fediuck 25 Apr '14

Sharing with ovirt devel list to get additional awareness. ----- Original Message ----- From: "Fabian Deutsch" <fabiand(a)redhat.com> To: "node-devel" <node-devel(a)ovirt.org> Sent: Thursday, April 24, 2014 5:57:07 PM Subject: [node-devel] Node Design ideas - And what you would like to see in or how you would like to see Node Hey, lately - well for some time now - I noticed how often I asked myself why we had this or that bug, or why it was so hard to implement some features. For example. Getting iSCSI and EFI right in our installer is still "fragile". Because it's hard to get right. Or enabling and disabling services easily with standard tools at runtime on our Fedora based images is not possible, because it's not easily implementable with bind mounts (well, cumbersome). Or enable "live plugins" - plugins which can be installed at runtime. They are also difficult because of our use of bind mounts. Because of this I thought about how we could - from the ground up - change some designs to leverage more existing code (and have less code to maintain) and make some feature development easier. The two areas I looked at are already mentioned. It's the (a) installer - which is complex because of all the storage enumeration [0], EFI, iSCSI and it's age - and (b) how we work with the read-only rootfs - aka the LiveCD based design. For (a) I looked into Fedora's anaconda [1]. It has support for EFI, iSCSI and so one. Even high-level features to configure networking or add users (for which we also maintain some code). And for (b) I thought about a design based around LVM and thin volumes [2][3]. But changing parts of Node might result in Node having different properties. For example - Using the LVM based approach above would increase the size of the runtime rootfs to ~1GB. OTOH it would allow an arbitrary number of "layers" (for e.g. live plugins). And thus - before I start to think (only to think) about bigger changes in Node - I would like to know what properties of Node _you_ like, and which you would like to keep. Some ideas about what you could like or not: - installation size (~250MB)? - runtime size (~250MB)? - way of installation (kargs)? - TUI (simple instaler, setup)? - "firmware-like" feeling (read-only rootfs)? - ... And also - what changes you would like to see which ain't there yet!

Feature AAA JDBC password hashing
by Sven Kieske 24 Apr '14

24 Apr '14

Hi, I got a question/remark regarding this page: http://www.ovirt.org/Features/AAA_JDBC It states: Account Password Hash function, default sha256 Well this is not a secure default. I don't know if nothing better can be used but here are some viable alternatives, in decreasing order (when we talk about security): scrypt, bcrypt, PBKDF2 Would it be possible to use one of these as a default? -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

[ACTION REQUESTED] please review new oVirt look-and-feel patch
by Greg Sheremeta 23 Apr '14

23 Apr '14

Hi, A while back, I sent out an email for the new oVirt look-and-feel feature [1]. The new look and feel patch is ready for both code and UI review. At this point we're not looking for design review, although you are welcome to suggest design improvements. I'm mostly looking for help regression testing the entire UI. Especially if you're an oVirt *UI* developer, please download the patch and try it [2]. The patch introduces some new CSS globally, and I had to adjust many screens and dialogs. It's quite possible that there are dialogs that I don't know about, so if you maintain any especially-hidden dialogs, please try the patch and verify your dialogs look good. And you can also just try out the patch to see the amazing new look and feel! Thanks for your feedback.

[vdsm] NUMA support broken on UMA machines

Hi, Commit 9d3311320f6fcf190c99068b3f566e2bf9a49d99 "caps: Collect numa information" bruce <xiao-lei.shi(a)hp.com> Introduced reporting of numa-related information in the getVdsCaps verb. Unfortunately it also introduced a bug in machines without NUMA support. On my mini-dell, the getVdsCaps verb is failing with the following exception: Thread-13::ERROR::2014-04-21 11:57:09,908::BindingXMLRPC::1068::vds::(wrapper) l ibvirt error Traceback (most recent call last): File "/usr/share/vdsm/BindingXMLRPC.py", line 1061, in wrapper res = f(*args, **kwargs) File "/usr/share/vdsm/BindingXMLRPC.py", line 388, in getCapabilities ret = api.getCapabilities() File "/usr/share/vdsm/API.py", line 1193, in getCapabilities c = caps.get() File "/usr/share/vdsm/caps.py", line 458, in get caps['numaNodes'] = _getNumaTopology() File "/usr/lib64/python2.7/site-packages/vdsm/utils.py", line 958, in __call__ value = self.func(*args) File "/usr/share/vdsm/caps.py", line 189, in _getNumaTopology memInfo = _getMemoryStatsByNumaCell(int(cellIndex)) File "/usr/share/vdsm/caps.py", line 203, in _getMemoryStatsByNumaCell return libvirtconnection.get().getMemoryStats(cell, 0) File "/usr/lib64/python2.7/site-packages/vdsm/libvirtconnection.py", line 92, in wrapper ret = f(*args, **kwargs) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 3405, in getMemoryStats if ret is None: raise libvirtError ('virNodeGetMemoryStats() failed', conn=self) libvirtError: internal error: NUMA isn't available on this host I guess we need to catch this error and respond appropriately. -- Adam Litke

Re: [ovirt-devel] [Engine-devel] ui plugin problems, cannot read from a file.
by Vojtech Szocs 18 Apr '14

18 Apr '14

Hi guys, > hey, am trying to display the contents of a text file in a java > applet as a ui plugin in ovirt. > The same applet performs successfully when run as a standalone, but > fails to deliver when the it is run through ovirt. UI plugins are written in JavaScript and HTML. UI plugin is technically standalone web application sandboxed within invisible <iframe> element under WebAdmin's DOM. UI plugin uses API to extend existing WebAdmin functionality through custom UI components (main tab, dialog, etc). Java applet technology cannot be used to implement UI plugin because plugin vs. WebAdmin integration happens on JavaScript/HTML level. I suggest to check out samples-uiplugins git repo for examples: http://www.ovirt.org/Features/UIPlugins#Sample_UI_plugins If you really want to write UI plugin in Java language, you can use GWT (as suggested by Greg) which yields JavaScript/HTML output. In general, any technology/language that ultimately yields JavaScript code can be used to implement UI plugin. > isn't one of the points of a uiplugin it doesn't have to be GWT based > (as its not going to be part of the codebase)? In fact, UI plugins can be written in GWT, if desired. However, as you mentioned, plugins are decoupled from WebAdmin code base through the plugin infra/subsystem.
