19:09	Chules	Hello All
19:10	JonasNZ	hi
19:11	solarce	As you gaze into the all encompassing All, try to find yourself, but get lost in the bottomless abyss of meaninglessness that is you
19:11	Chules	lol
19:11	Chules	I have a few questions about uml
19:11	solarce	there is no uml, only the All
19:12	Chules	In the HOWTO sections about "Compiling the Kernel", which kernel are we compiling? The host's kernel or the "virtual machine"'s kernel?
19:12	Chules	OK ... is just "Hello" better?
19:12	Chules	I am very new to UML
19:12	Chules	JonasNZ and I are trying to set it up
19:13	JonasNZ	whaoh am I?
19:13	JonasNZ	oh yeah thats right
19:13	Chules	In the HOWTO sections about "Compiling the Kernel", which kernel are we compiling? The host's kernel or the "virtual machine"'s kernel?
19:13	solarce	Chules: the virtual
19:13	solarce	although "instance" is a better term
19:13	Chules	ok
19:14	solarce	it took me a loooooooooong time to figure that :)
19:14	Chules	Have you ever compiled it on a 64-bit machine?
19:14	solarce	no sir
19:14	solarce	only on my pdp11
19:14	solarce	;)
19:14	Chules	heh
19:14	Chules	I'm having problems with it on a 64 bit machine
19:15	Chules	It says it can't find the makefile for x86_64
19:16	solarce	I'd consult the mailing list tbh
19:16	solarce	possibly the wiki, if they fixed it
19:16	Chules	Where can I find the wiki?
19:17	JonasNZ	chules: http://uml.harlowhill.com
19:17	solarce	Chules: /topic
19:17	solarce	still broke :/
19:17	Chules	:(
19:18	Chules	Mailing list it is, then
19:19	JonasNZ	how stable are the 2.6 kernels with UML?
19:23	Chules	I believe UML is included by default with 2.6
19:26	JonasNZ	[uml@w00t linux]$ make config ARCH=um # Not forgetting it this time ...
19:27	JonasNZ	arch/um/Makefile:18: arch/um/Makefile-x86_64: No such file or directory
19:27	JonasNZ	make: *** No rule to make target `arch/um/Makefile-x86_64'. Stop.
19:27	JonasNZ	any ideas?
19:27	Chules	[uml@w00t linux]$ make config ARCH=um
19:27	Chules	arch/um/Makefile:18: arch/um/Makefile-x86_64: No such file or directory
19:27	Chules	make: *** No rule to make target `arch/um/Makefile-x86_64'. Stop.
19:27	Chules	[uml@w00t linux]$
19:28	JonasNZ	lol Chules i already pasted it
19:28	Chules	o well

23:30	Chules	Hello Everyone - Can someone here tell me exactly how UML works? I don't mean how to use it, I mean how it actually works.
23:38	Chules	Anyone?
23:38	Chules	Please?
23:39	Newsome	Chules, UML works by translating system calls
23:40	Chules	Which system calls?
23:40	Chules	Just to the hardware?
23:42	Newsome	for example, to write to the disk, you normally use a system call that does the hardware write.
23:42	Newsome	Anything that's not purely virtual, I believe
23:43	Chules	I'm still trying to get it to run
23:44	Chules	I've tried all combinations of an amd64 host, i686 host, 2.4 uml kernel, and 2.6 uml kernel and none will compile. They all give different errors.
23:45	Chules	What uml kernel version do you use?
23:45	Newsome	Most recent 2.x
23:45	Chules	So, 2.6.* ?
23:46	Newsome	Currently 2.6.11 should run a very stable UML
23:46	Chules	Is there a 2.6.11 patch?
23:46	Newsome	no patches necessary for 2.6.11
23:47	Chules	For the guest kernel?
23:48	Newsome	yes
23:48	Chules	cool
23:49	Newsome	There are some host patches that will significantly improve performance, but they're not absolutely required
23:49	Chules	The host is running 2.6.10
23:49	Chules	Are the patches included?
23:50	Newsome	No, look at the links in the channel topic for the SKAS patch
23:50	Chules	ok
23:51	Chules	So, to compile the 2.6 kernel for uml, I just do: make menuconfig ARCH=um && make linux ARCH=um
23:51	Chules	right?
23:52	Newsome	yep
23:52	Chules	:)
23:52	Chules	Thanks a lot!
23:55	Chules	Hmmm
23:55	Chules	Are you still here?
