12:20 < riel> ahhh, gotta love the subtleties of context switching code
12:20  * riel tries Keir's smp bugfix in the Fedora kernel
12:22 < Sir_Ahzz> mmm smp
12:22 < riel> looks like I might be able to get xen in a very nice shape for fedora core 4, test 2
12:59 -!- MarkW [~MarkWilli@hebble.cl.cam.ac.uk] has joined #xen
13:02 < Arnald> is there any way to control the vif numbers?
13:03 < Arnald> my gkrellm net window is about six feet wide ;)
13:04 < Arnald> if I could just stop them incrementing each time I do an xm create . . .
13:04 < Sir_Ahzz> heh
13:04 < mikegrb> EEE
13:05 < Sir_Ahzz> use the agregate gkrelm net monitor then.
13:05 < Arnald> so far up to vif76.0 ;)
13:06 < Arnald> Sir_Ahzz: I have a little tidying up to do first!
13:07 < Arnald> Sir_Ahzz: BTW, never heard of it, is it part of gkrellm, or an add-on?
13:07  * Arnald wonders if the counter eventually wraps around, or just blows up! ;)
13:07 < riel> only one way to find out
13:08 < Arnald> riel: or I could ask you ;)
13:09 < riel> I might test it after the Xen summit

13:10 < Arnald> riel: I will keep going as long as the machine stays up - at least Xen appears to be fairly stable ATM
13:10 < riel> yes, it would appear so
13:10 -!- hebutterworth [~harry@blueice1n1.uk.ibm.com] has quit [Remote host closed the connection]
13:10 < riel> the only thing that keeps driving me nuts is the incompatible changes in the kernel/hypervisor interface ;)
13:12 < Arnald> er, right - good luck with that ;)

13:14  * riel wonders when the RHN people will notice that 3 CPU RHEL4 system in their statistics
13:26 < MarkW> Arnald: I think the theory is that Xen domain IDs don't wrap
13:27 < MarkW> so it's only going to get worse for your gkrellm :-)
13:27 -!- MadMethod [Method@pcp0010742058pcs.howard01.md.comcast.net] has joined #xen
13:27 < MarkW> I don't actually know how large an integer Linux can cope with as an ethernet device number.  presumably quite large...

13:34 < cw> it's really a string, you can even change it on the fly
13:35 < cw> i think the limit is 16 chars but i would have to check
13:38 < Arnald> MarkW: OK thanks, I'll bear that in mind ;)
13:39 < MarkW> i think domids are 16 bits these days
13:40 < MarkW> so i guess it might fit in there
13:40 < MarkW> for your own sanity with gkrellm, you could maybe hack the network scripts to rename the devices (i think you can do that...)
13:43 < Arnald> MarkW: yes, just checked, gkrellm seems to create virtual interfaces on-the-fly ie. no config files I can edit
13:44 < MarkW> i meant the Xen network scripts
13:44 < MarkW> there's a script that's called every time a vif is created, maybe there's something you can do with that
13:44 < Arnald> MarkW: yes, I know - just pointing out that the alternative is not an option
13:45 < Arnald> thanks
13:45 < MarkW> ah ok
13:45 < MarkW> cheers
13:56 < knewt> Arnald: gkrellm doesn't get rid of the old vifs when the old domains are shut down?
15:17 < MarkW> knewt: i think his problem is the length of the Xen domain IDs over time
15:17 < MarkW> when the domain IDs get big, so do the vif numbers

19:25 < Arnald> knewt: sorry for the delay, but no ;)
19:25 < Arnald> anyway, bedtime here - g'night all
19:34 < MarkW> Arnald: good night
19:36  * riel is looking forward to the xen summit
19:39 < knewt> gah. have a good time.
19:41 < riel> doubtful ;)
19:41 < riel> we're flying out overnight from tuesday to wednesday
19:42 < riel> I'll probably feel pretty bad most of the time
19:43 < knewt> hmm. thinking about it, yeah. i always feel worse when going east compared to going west. well, on long haul anyway
19:44  * riel is counting on 2-3 hours resting time between arrival in cambridge and the start of the xen summit
19:44 < Sir_Ahzz> owww. 
19:44 < riel> after skipping a night
19:44 < Sir_Ahzz> finally got the stump chopped out, but my back hurts now. 8-P

19:47 < knewt> well, if not a good time then have a productive time. wish i was going to be there, but can't be helped.
19:47 < MarkW> Sir_Ahzz: well done, chainsaw fixed?
19:47 < Sir_Ahzz> yeah, too much sandy dirt to use it on the lower roots though. 8-P
19:47 < Sir_Ahzz> it'll be usefull to cut up the stump though. :)
19:47 < Sir_Ahzz> 2.5 ft diameter.
19:48 < Sir_Ahzz> the chansaw has an 18" blade. barely long enough to get 1/2 way through it.
19:49 < MarkW> problematic!
19:50 < Sir_Ahzz> nah. slice down one side, turn it 90 deg, slice, repeat till cut.
19:52 < Sir_Ahzz> the sucky part is the sunburn I got yesterday.
19:52 < Sir_Ahzz> but, no more rotten smelly stump right next to the front door. :)
19:52 < Sir_Ahzz> it was starting to really smell.
19:52 < MarkW> ewww!
19:53 < Sir_Ahzz> gonna play some lbreakout2 before I have to go fix dinner.
19:53  * knewt ponders going to sleep, it being almost 2am
19:59 < MarkW> knewt: the night is still young!

21:34 < Andrew_> hi, has anyone here had problems enabling dma on an ide drive after booting with the xen kernel?  after I use xen I get an operation not permitted when I try to enable dma
21:39 < rusty> Andrew_: CONFIG_PCI_IDE=y?
21:54 -!- mael [~mael@nat.inha.fr] has quit [Ping timeout: 480 seconds]
22:57 < Andrew_> rusty: sure, does that mean I have to recompile xen? or is that an option somewhere else?
22:59 < riel> in the dom0 kernel
23:01 -!- MarkW [~MarkWilli@hebble.cl.cam.ac.uk] has quit [Quit: Kopete 0.9.2 : http://kopete.kde.org]
23:01 < Andrew_> ah, strange... thats not in the one thats in the binary dist?
23:02 < riel> dunno, I don't use the binary dist from xensource
23:02  * riel builds the Fedora RPMs ;)
23:02 < Andrew_> ah haha
23:03 < Andrew_> ok, well Ill definitely check that... the only hint I had before was that I might need to specify the exact chipset or something
23:03 < riel> (and those seem to work)
23:03 < Andrew_> cool
23:03 < riel> if you find a problem with the Fedora RPMs, file a bugreport and I'll look into it
23:03 < Andrew_> I was trying to get it working quick for some tests and used knoppix and installed to HD
23:03 < rusty> Andrew_: I had this same problem w/o Xen.
23:03  * riel hopes the xensource people can focus on xen development, and not on packaging issues ;)
23:04 < Andrew_> I might try that, Ive never been font of redhat/fedora though hehe
23:04 < Andrew_> rusty: ah ok
23:04 < riel> Andrew_: you could use Debian's xen 1.2 RPMs ;)
23:04  * riel runs
23:04 < riel> ummm s/RPMs/debs/
23:04 < Andrew_> wow, I think Ill try the debs
23:04 < riel> they're only 2 years out of date
23:04 < Andrew_> if I say gentoo next, are you going to tell me theres an ebuild? :-D
23:05 < Andrew_> oh haha, right 1.2
23:08 < Andrew_> I haven't actually played with Xen much... I was working with something called coLinux which works very similar to Xen (with less protection) but couldn't manage to get it to compile with linux as the host
23:08 < Andrew_> and then I recently found out about Xen and its binary distribution worked out of the box so I figured that would be worth a try
23:10 < riel> Xen seems to be working pretty well so far
23:10 < riel> I've put some reasonably heavy stress tests on the RPMs that will go into FC4 test 2
23:10 < Andrew_> nice
23:11 < Andrew_> Im amazed that its open source, it seems to be a very elegant solution, which OSS is not usually known for ;-)
23:11  * riel starts another aim7 run  ;)
23:11 < Andrew_> aim7?
23:12 < riel> you've never seen proprietary software from nearby, have you? ;)
23:12 < riel> OSS is surprisingly clean compared to some other software
23:12 < riel> you can see that every time some piece of formerly closed source software is released as open source
23:12 < Andrew_> haha you are correct, I guess the proprietary stuff is only elegant as far as its the standard
23:13 < riel> just look at the original Mozilla codebase
23:13 < riel> as one example
23:13 < riel> or some of the device drivers that have been opened up by vendors
23:14 < Andrew_> oh I meant elegant only as far as the user experience hehe
23:14 < Andrew_> but Im also not complaining, everything I use is open source except vmware
23:15 < Andrew_> and hopefully if I ever release any software it will be OSS
23:15 < riel> I've seen user experience improve across the board, both open and closed software
23:16 < Andrew_> agreed, like installing knoppix the other day, that was the easiest operating system install Ive ever worked with :)
