| 02:12 | mael | hi chrish01 |
| 02:13 | chrish01 | howdy |
| 02:13 | chrish01 | i think i found a gtk+ bug today with treeviews :( |
| 02:14 | mael | have you checked the work on gXenophilia? |
| 02:14 | mael | http://cosi.clarkson.edu/xen/screenshots/ |
| 02:14 | chrish01 | no i havent |
| 02:14 | mael | seems pretty much the same approach |
| 02:15 | chrish01 | there interface pretty much sucks though |
| 02:15 | mael | even though some of their choices for the interface are *weird* |
| 02:15 | mael | yeah |
| 02:15 | chrish01 | i think this will be feature comparitive by sunday |
| 02:16 | | * mael don't understand why they put the domain state in configuration for instance |
| 02:16 | mael | as you can't change it |
| 02:16 | chrish01 | i think i found a bug though today with treestores and them being updated by the gtk.timeout stuff |
| 02:16 | chrish01 | if a popup menu is shown it locks X :( |
| 02:16 | chrish01 | should have a test case done in a few |
| 02:17 | mael | chrish01: what are your plans for xenmanager? |
| 02:17 | mael | licence/goals/etc... |
| 02:17 | chrish01 | mael, i have two companies funding its development |
| 02:17 | chrish01 | GPL |
| 02:18 | chrish01 | i just started on monday, but medsphere wants it to manage the deployment platform they will be shipping with their medical software (im doing the platform as well) |
| 02:18 | chrish01 | and mosaix wants it for managing their virtual routers running on xen |
| 02:18 | mael | ok |
| 02:19 | mael | do you have a feature list somewhere? |
| 02:19 | chrish01 | ill setup a trac site over the weekend |
| 02:19 | --- | <<-- Tv [~Tv@hq.inoi.fi] has quit (Quit: Client exiting) |
| 02:19 | chrish01 | mael, to start with, i think everything that xm does would be nice |
| 02:19 | mael | cool |
| 02:19 | mael | yeah probably |
| 02:20 | chrish01 | but i want some plugins like snmp extensions as well |
| 02:20 | mael | thought I think xm is too much a low level stuff |
| 02:20 | chrish01 | so you could have something like gnome-system-monitor's cpu graph for domains :) |
| 02:20 | mael | yeah that could be useful |
| 02:21 | mael | along with memory and network graph |
| 02:21 | chrish01 | yea |
| 02:21 | mael | knowing how much ressources are used in a vm is a first start |
| 02:21 | chrish01 | i have it polling every 5 seconds right now |
| 02:21 | chrish01 | but that will be configurable |
| 02:21 | mael | then being able to apply policies is a second one |
| 02:21 | chrish01 | policies? |
| 02:22 | mael | not security ones |
| 02:22 | mael | but strong ressources partitionning |
| 02:22 | mael | with two different possible approach |
| 02:23 | chrish01 | i had some ideas with templates, but not sure where that is gonna go |
| 02:23 | mael | either you specify a global ressource sharing, either you do it for each ressource |
| 02:23 | chrish01 | well, if you know or can learn python, you are welcome to hack on this too. ill try to put code up tomorrow morning |
| 02:23 | chrish01 | i just started learning python on monday lol |
| 02:23 | chrish01 | but its pretty simple |
| 02:24 | mael | in the first case, you need a high level logic that will evaluate the bottleneck and adapt individual ressource sharing accordingly |
| 02:24 | mael | well I'm more a sysadmin |
| 02:24 | chrish01 | that sounds interesting |
| 02:24 | mael | I can think of usages but coding is another matter... |
| 02:25 | chrish01 | heh |
| 02:25 | | * mael is trying to write an article on xen usages and what's needed |
| 02:25 | chrish01 | cool |
| 02:26 | mael | but I have a lot of stuff happening in the same time, it's a bit in a "standby" mdoe |
| 02:26 | mael | -mdo+mode |
| 02:26 | mael | and I'm not a native english writer... |
| 02:27 | chrish01 | no biggy |
| 02:27 | mael | yeah but it's very frustrating :) |
| 02:27 | chrish01 | i run the seattle pop for mosaix (private isp for corporations). we use xen for our virtual routers there so we dont have to buy expensive alcatel or juniper routers |
| 02:27 | chrish01 | pretty sweet setup actually |
| 02:28 | mael | do you use Zebra? |
| 02:28 | chrish01 | yes |
| 02:28 | chrish01 | well quagga |
| 02:28 | mael | yup |
| 02:28 | chrish01 | we do full on dynamic routing, firewall, traffic shaping, ipsec, pptp, etc ... |
| 02:28 | mael | yeah I was thinking on a setup with quagga daemons running on domU |
| 02:29 | chrish01 | thats what we do :) |
| 02:29 | chrish01 | we used to do it on UML until around january |
| 02:30 | mael | the setup I think of would use vm "forking" to be able to ugrade the daemons with zero downtime |
| 02:30 | chrish01 | we use lvm, so migration still has some issues for us :( |
| 02:30 | mael | and that would allow rollback in case of problem (thought for now rollback will make you loose info) |
| 02:31 | tessier | Wow, someone who uses quagga. How does quagga compare to zebra? What's the difference? |
| 02:32 | mael | it's working :) |
| 02:32 | chrish01 | its simply the evolution |
| 02:32 | tessier | Wish I could get my company to look at quagga. |
| 02:32 | mael | tessier: you're using zebra? |
| 02:32 | tessier | Neither. Using Cisco. |
| 02:32 | tessier | And it sucks. |
| 02:32 | mael | zebra is a bit outdated |
| 02:32 | chrish01 | xen + quagga + linux saved us around a million dollars |
| 02:32 | chrish01 | and we are a startup |
| 02:32 | tessier | Cisco and Juniper. |
| 02:32 | chrish01 | junipers are so $$ |
| 02:32 | mael | well Juniper is not so bad |
| 02:32 | tessier | chrish01: You really should write up a basic whitepaper on that. That would be big. |
| 02:33 | chrish01 | tessier, i have one for investors right now |
| 02:33 | mael | actually some of my friends are running a small isp company |
| 02:33 | tessier | There are not nearly enough people documenting from first hand experience how Linux has saved them money. |
| 02:33 | chrish01 | tessier, maybe i get it /. and we get some cash |
| 02:33 | chrish01 | we need around 500k funding right now |
| 02:33 | chrish01 | to expand |
| 02:33 | tessier | chrish01: For investors? Is it something you can share with the general public? |
| 02:33 | mael | and they traded their quagga routers with a Juniper |
| 02:33 | chrish01 | tessier, yes |
| 02:33 | tessier | mael: Why did they get rid of quagga for juniper? |
| 02:33 | mael | for performance |
| 02:34 | chrish01 | tessier, maybe i write a whitepaper for this and release it at same time i publicly release xenmanager code :) |
| 02:34 | tessier | The only big reason to go with cisc/juniper: You are doing gigabits of bandwidth. |
| 02:34 | chrish01 | that could be helpful |
| 02:34 | mael | high availability |
| 02:34 | tessier | Someone needs to design some PCI router hardware for Linux that has a fast path. |
| 02:34 | chrish01 | juniper is rock solid |
| 02:34 | chrish01 | but |
| 02:34 | tessier | So the packets don't have to go through the cpu/bus. |
| 02:34 | chrish01 | since we are mostly oc3 and ds3, SBS has good pci card and linux SDK |
| 02:37 | mael | mmh my friend told me I was wrong :) |
| 02:37 | mael | they changed for foundry |
| 02:38 | mael | BGP route management is better, failover is handled more efficiently also at the ip level |
| 02:38 | chrish01 | foundry is nice too |
| 02:39 | chrish01 | we are gonna buy a foundry core router |
| 02:39 | chrish01 | err switch, not router |
| 02:39 | mael | well switch/routing is not so separate today |
| 02:39 | mael | as most of the routing stuff is done in asic |
| 02:40 | mael | like CEF on cisco |
| 02:40 | chrish01 | yup |
| 02:41 | mael | chrish01: are the nic/hd/memory icons on your interface relative to devices exported to the vm? |
| 02:42 | mael | is it intended to be similar to vmware interface? |
| 02:42 | chrish01 | yup |
| 02:42 | chrish01 | exactly |
| 02:42 | mael | (flashing when there's traffic for instance) |
| 02:42 | chrish01 | it gets the devices via the xend protocol |
| 02:42 | chrish01 | no :( |
| 02:42 | chrish01 | that would be overkill :) |
| 02:42 | mael | would it be possible to print the device name below then? |
| 02:43 | chrish01 | not from the config information |
| 02:43 | chrish01 | since that is specific to how the domain OS interprets them |
| 02:43 | mael | mmh :\ |
| 02:43 | mael | yeah |
| 02:43 | mael | sure |
| 02:43 | mael | well it's coffee time here :) |
| 02:44 | chrish01 | ok, have a good one |

| 03:02 | chrish01 | yea, no more treeview problem :) |
| 03:08 | mael | chrish01: so where was the bug? |
| 03:09 | chrish01 | in my timeout loop |
| 03:10 | chrish01 | i chock it up to knowing pythong for only 4 days |
| 03:10 | mael | you knew gtk before? |
| 03:10 | chrish01 | yes |
| 03:10 | chrish01 | i hack on the gtk# bindings for mono |
| 03:11 | chrish01 | and slightly familiar with gobject and gtk+ in C |
| 03:11 | chrish01 | obviously the use the the libxen-python outweighed the benefits of a comfortable language :) |
| 03:13 | mael | chrish01: you use http to connect to xen, right? |
| 03:13 | chrish01 | yes, i hope to support ssh tunnels at some point too |
| 03:15 | mael | that mean your interface hopefully don't have to run on the server, so you don't need python on dom0 |
| 03:15 | chrish01 | as long as a xend compatable api is running |
| 03:15 | chrish01 | which xend is written in python, so if vmtools replaces that then i would say yes |
| 03:16 | chrish01 | from what i can tell, the xend api is absolutely beautiful |

| 09:31 | doremifa | hi. in unstable, libxutil was moved into tools/vnet, so it is used only by vnet? |
| 09:34 | aliguori | doremifa: yes, that's a recent change |
| 09:35 | doremifa | aliguori: hi. but i dont see it get compiled? |
| 09:35 | aliguori | doremifa: vnet might not get compiled by default... |
| 09:35 | doremifa | tools/Makefile doesnt try to compile it |
| 09:35 | aliguori | doesn't surprise me. |
| 09:35 | aliguori | vnet is not normally used |
| 09:35 | doremifa | aliguori: ah, so how to compile it? cd vnet;make ? |
| 09:35 | aliguori | probably |
| 09:36 | doremifa | vnet stands for VPN? |
| 09:36 | doremifa | so they move libxutil into vnet because only vnet uses it? |
| 09:37 | aliguori | other stuff used to use it, but now only vnet does |
| 09:37 | aliguori | so they moved it |
| 09:38 | doremifa | aliguori: after the registry stable, do we still need xcs? |
| 09:38 | aliguori | it'll probably stay around for a while |

| 16:57 | ghpolo | but cant balloon raise aswell ? |
| 16:57 | ghpolo | after you decrease |
