14:11	<_kaenat>	When I startup uml with con0=fd:0,fd:1 con1=xterm, I can log in successfully from the "Virtual Console #1" xterm, but trying to login from the con0 console always results in "Login incorrect". Any ideas?
14:13	<jdike>	kaenat, you don't have tty0 in /etc/securetty
14:14	<_kaenat>	of course. Thanks :)

15:30	\|-\|	dominik [~dominik@83.65.240.150] has quit [Ping timeout: 480 seconds]
15:33	<kaenat>	Why might I be seeing: "BUG: soft lockup detected on CPU#0!" followed by a call stack?
15:38	<jdike>	Because UML can go 10 seconds without seeing a timer tick
15:39	<jdike>	especially under heavy I/O load
15:44	<_kaenat>	There isn't a lot of I/O going on that as far as I can tell. My setup is Windows XP running VMWare Player running Ubuntu running UML. I wonder if the problem VMWare. Any experience with this?
15:44	\|-\|	kaenat [~ringlej@webadmin.keyvoice.com] has quit [Read error: Connection reset by peer]
15:44	<jdike>	Is it really a problem, aside from the ugly messages?
15:46	<_kaenat>	Other than the noise factor, it's not a problem as far as I can tell.
15:47	<jdike>	There's a config setting for it
15:47	<jdike>	CONFIG_SOFTLOCKUP or something
15:48	<_kaenat>	ok. thanks

16:16	<robl>	Hi, is it possible to limit the host uml machines cpu usage at all ?
16:16	<jdike>	limit how?
16:17	\|-\|	cndougla [~cndougla@bi01p1.nc.us.ibm.com] has joined #uml
16:17	<cndougla>	Hi, I'm having a problem with a guest 2.6.16.20 kernel
16:17	<robl>	so a guest uml machine cant overload/suck up all the resources of the host machine
16:18	<cndougla>	everything says it's ok, but nothing happens and the program exits
16:18	<robl>	or am I looking at it the wrong way ?
16:18	<cndougla>	It prints "UML running in SKAS3 mode" and then I get dumped back to the prompt
16:19	<jdike>	cndougla, add stderr=1 to the command line
16:20	<robl>	or I guess maybe the question should be, how can you secure the uml host in such a way that it's resources aren't all used by the uml guest machines ?
16:20	<jdike>	robl, if it's the only thing running, you want it to suck up all the host's resources
16:20	<cndougla>	Ahh, I get "Kernel panic - not syncing: Segfault with no mm"
16:20	<cndougla>	And then a stack trace
16:21	<cndougla>	what does that mean?
16:21	<jdike>	paste the stack trace to pastebin or something
16:21	<cndougla>	pastebin?
16:22	<caker>	10 GOTO 10
16:22	<robl>	i'm running (on the host) munin for some network monitoring and apache to display the results, so I'd like these to run 'normally' even when my uml guests are running at full whack - or is this something I don't need to worry about ?
16:23	<jdike>	pastebin.com
16:23	<jdike>	robl, just nice it up
16:23	<caker>	robl: I've found that Linux's CPU scheduler does a perfect job of not letting any one process storm the system
16:23	<robl>	ok - thought that might be the answer :)
16:23	<robl>	thanks guys
16:23	<caker>	robl: disk schedulers however, is an entirely different story
16:24	<jdike>	caker has long done battle with I/O schedulers
16:24	[~]	caker nods
16:24	<cndougla>	ok, I've pasted it
16:24	<cndougla>	as user: cndougla
16:25	[~]	caker is now running UMLs off LVM partitions on hardware raid
16:25	<caker>	good stuff
16:25	<jdike>	cndougla, what's the URL
16:25	<caker>	jdike: http://pastebin.com/705227
16:26	<robl>	Are there any host/guest kernel patches to mitigate I/O scheduler issues ?
16:26	<cndougla>	yep
16:27	<jdike>	cndougla, that's a new one
16:27	<jdike>	can you put the binary someplace I can grab it?
16:27	<cndougla>	hmmm, should I downgrade to something previous
16:27	<cndougla>	doesn't really matter if it's 2.6.16.10 or 2.6.16.20
16:27	<cndougla>	if you know of one that is supposed to be stable
16:27	<caker>	robl: http://www.theshore.net/~caker/patches/token-limiter.README , the patches are in that dir, too .. the v4-testing one should apply without much pain to a more recent kernel
16:28	<jdike>	cndougla, better to let me find the bug and fix it
16:28	<cndougla>	ok
16:28	<cndougla>	I have to leave now
16:28	<caker>	robl: however, they'll likely be rejects (a line or two) that should be easy enough to hand-merge in (sorry, I haven't updated that patch in a while)
16:28	<cndougla>	I wouldn't mind helping
16:28	<jdike>	since I haven't seen this before, I can't guarantee it's not present earlier
16:28	<cndougla>	could you e-mail me when you know anything?
16:28	<cndougla>	or if you need any help
16:28	<jdike>	send me the binaruy
16:28	<jdike>	binary
16:29	<jdike>	can't do much without it
16:29	<cndougla>	over irc?
16:29	<jdike>	email or http
16:29	\|-\|	tyler [~tyler@86.220.204.3] has quit [Ping timeout: 480 seconds]
16:29	<cndougla>	what's your http address?
16:30	<jdike>	uh
16:30	<robl>	thanks caker - I'll have a look :)
16:30	<jdike>	if you have web space of your own, you can put it there and send me the URL
16:30	<cndougla>	I see what you're saying
16:30	<cndougla>	sorry
16:30	<cndougla>	I don't have any http space that I can easily set up
16:30	<cndougla>	so what is your e-mail?
16:30	<jdike>	otherwise attach it to an email to jdike@addtoit.com
16:30	<cndougla>	ok
16:30	<cndougla>	thanks very much
16:33	<cndougla>	ok, e-mail's sent
16:33	<cndougla>	thanks again
