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
12:23	@riel	looks like I might be able to get xen in a very nice shape for fedora core 4, test 2

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	@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	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

22:01	Andrew_	ah, strange... thats not in the one thats in the binary dist?
22:02	@riel	dunno, I don't use the binary dist from xensource
22:02		* riel builds the Fedora RPMs ;)
22:02	Andrew_	ah haha
22:03	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
22:03	@riel	(and those seem to work)
22:03	Andrew_	cool
22:03	@riel	if you find a problem with the Fedora RPMs, file a bugreport and I'll look into it
22:03	Andrew_	I was trying to get it working quick for some tests and used knoppix and installed to HD
22:03	rusty	Andrew_: I had this same problem w/o Xen.
22:03		* riel hopes the xensource people can focus on xen development, and not on packaging issues ;)
22:04	Andrew_	I might try that, Ive never been font of redhat/fedora though hehe
22:04	Andrew_	rusty: ah ok
22:04	@riel	Andrew_: you could use Debian's xen 1.2 RPMs ;)
22:04		* riel runs
22:04	@riel	ummm s/RPMs/debs/
22:04	Andrew_	wow, I think Ill try the debs
22:04	@riel	they're only 2 years out of date
22:04	Andrew_	if I say gentoo next, are you going to tell me theres an ebuild? :-D
22:05	Andrew_	oh haha, right 1.2
22:08	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
22:08	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
22:10	@riel	Xen seems to be working pretty well so far
22:10	@riel	I've put some reasonably heavy stress tests on the RPMs that will go into FC4 test 2
22:10	Andrew_	nice
22:11	Andrew_	Im amazed that its open source, it seems to be a very elegant solution, which OSS is not usually known for ;-)
22:11		* riel starts another aim7 run ;)
22:11	Andrew_	aim7?
22:12	@riel	you've never seen proprietary software from nearby, have you? ;)
22:12	@riel	OSS is surprisingly clean compared to some other software
22:12	@riel	you can see that every time some piece of formerly closed source software is released as open source
22:12	Andrew_	haha you are correct, I guess the proprietary stuff is only elegant as far as its the standard
22:13	@riel	just look at the original Mozilla codebase
22:13	@riel	as one example
22:13	@riel	or some of the device drivers that have been opened up by vendors
22:14	Andrew_	oh I meant elegant only as far as the user experience hehe
22:14	Andrew_	but Im also not complaining, everything I use is open source except vmware
22:15	Andrew_	and hopefully if I ever release any software it will be OSS
22:15	@riel	I've seen user experience improve across the board, both open and closed software
22:16	Andrew_	agreed, like installing knoppix the other day, that was the easiest operating system install Ive ever worked with :)
