14:51	<kmacy>	aliguori: I found two problems
14:51	<kmacy>	guess what
14:51	<aliguori>	k
14:51	<aliguori>	?
14:51	<kmacy>	1) older hvmloader doesn't work
14:51	<aliguori>	yeah, i saw your note
14:51	<kmacy>	needed to rebuild
14:51	\|-\|	womble [~mpalmer@eth359.nsw.adsl.internode.on.net] has joined #xen
14:52	<kmacy>	2) disk format change between qemu 0.6.1 and 0.7.2
14:52	<aliguori>	ahhh
14:52	<aliguori>	you were using an old qemu :-)
14:52	<kmacy>	No YOU're using an old qemu
14:52	<aliguori>	heh
14:52	<kmacy>	I used 0.7.2 and 0.8.0
14:52	[~]	aliguori is confused
14:52	<aliguori>	oh
14:52	<kmacy>	which work fine with the image I created last night
14:52	<aliguori>	you're saying qemu-dm is based on 0.6.1?
14:52	<kmacy>	qemu-dm is 2 years old
14:52	<kmacy>	yes
14:52	<aliguori>	oh
14:52	<aliguori>	i see
14:53	<aliguori>	i always use raw format with hvm
14:53	<aliguori>	so i've not had that problem
14:53	\|-\|	xterminus [nobody@00104bc8bd59.click-network.com] has quit [Ping timeout: 480 seconds]
14:53	<kmacy>	I found that, although not listed, I could still grab 0.6.1 form Fabrice's site
14:53	<kmacy>	It won't accept raw scsi
14:54	<kmacy>	it looks like it will only accept raw ide
14:54	<aliguori>	ah
14:54	<kmacy>	anyway tried booting my image with 0.6.1 and I got the same error
14:54	<kmacy>	so now I'm installing XP with 0.6.1
14:55	<aliguori>	ah
14:55	<aliguori>	you can always use qemu-img convert
14:55	<aliguori>	to convert it to a raw format
14:55	<kmacy>	hmm
14:56	<kmacy>	for example?
14:56	<aliguori>	qemu-img convert myimage.img -O raw myimage.raw
14:57	<kmacy>	ahh
14:57	<kmacy>	how is "raw" different
14:57	<aliguori>	raw is like a hard disk image
14:57	<aliguori>	so it's the same in all qemu versions
14:58	<kmacy>	Alright
15:00	<kmacy>	converting now
15:05	<kmacy>	well I'll see if you're right now
15:05	<aliguori>	so little faith...
15:05	<aliguori>	:-)
15:06	\|-\|	xterminus [nobody@00104bc8bd59.click-network.com] has joined #xen
15:09	<kmacy>	nope
15:09	<kmacy>	no dice
15:09	<kmacy>	The current install will finish in about an hour
15:09	<kmacy>	I'll try that
15:12	<cfreak>	can i use the same virtual mac address twice on the same server?
15:15	<kmacy>	cfreak: a mac address is a mac address
15:15	<felix>	cfreak: I think it'll be dangerous
15:15	<kmacy>	everything arps to map IPs to MACs
15:16	<kmacy>	there is no way that that could work reliably
15:16	<kmacy>	unless you never ran the two VMs at the same time

16:56	<kmacy>	aliguori: has anyone use a cdrom with HVM?
16:56	<kmacy>	they appear to have messed it up
16:56	<kmacy>	0.6.1 is a bit crippled in that it can only do it from a file, but HVM appears to not even be able to do that

18:32	<kmacy_>	aliguori: I just download linux-test from qemu
18:33	<kmacy_>	I've never seen anything boot so fast
19:19	<aliguori>	:)
19:19	<aliguori>	and it worked under hvm?
19:19	<aliguori>	or just qemu

21:21	<kmacy_>	aliguori: ping
21:22	<kmacy_>	aliguori: it worked under both
21:22	<kmacy_>	aliguori: My current supposition is that HVM currently doesn't really support xp
21:25	<kmacy_>	actually that 0.6.1 doesn't support xp
21:25	<kmacy_>	the screen will pop up
21:25	<kmacy_>	then go away
21:30	<aliguori>	hrmm
21:30	\|-\|	mdday [~mdday@cpe-024-163-120-222.nc.res.rr.com] has quit [Quit: mdday]
21:30	<aliguori>	you should try win2k
21:30	<kmacy_>	at least I can say:
21:31	<kmacy_>	1) I've successfully booted an OS on SVM
21:31	<kmacy_>	2) I've tried every permutation conceivable with XP
21:33	<kmacy_>	I now feel I've earned my box - and definitely want a more recent rev of the microcode
21:33	<kmacy_>	this bites
21:34	<aliguori>	:-D
21:34	<kmacy_>	well that would be a headache
21:34	<aliguori>	?
21:34	<kmacy_>	as best I can tell the CDROM option doesn't work with their qemu-dm
21:35	<kmacy_>	0.7.2 can use a real cd drive
21:35	<kmacy_>	0.6.1 needs a file
21:35	<aliguori>	yes
21:35	<kmacy_>	and qemu-dm won't even boot the file I give it
21:35	<aliguori>	even with a proper -boot d?
21:35	<kmacy_>	It will try
21:35	<kmacy_>	but it gets error 0003
21:35	<aliguori>	hrm
21:43	<kmacy_>	another thing
21:43	<kmacy_>	qemu won't do slices or grub
21:44	<aliguori>	?
21:44	<kmacy_>	boot off a partition or copy of a partition in a file hangs
21:44	<aliguori>	huh
21:44	<kmacy_>	booting directly off the hard drive appears to work
21:44	<kmacy_>	but XP will weird out
21:44	<kmacy_>	when selected from GRUB
21:45	<kmacy_>	and Xen will panic when constructing dom0 - but that might just be inadequate memory
21:52	<kmacy_>	CDROM boot failure code : 0003
21:52	<kmacy_>	Boot from CD-Rom failed
21:52	<kmacy_>	FATAL: Could not read the boot disk
21:53	<kmacy_>	this is what it gives me when I give an argument to cdrom, and set boot to d
21:55	<kmacy_>	aliguori: question
22:09	<kmacy_>	aliguori: ping

23:19	<kmacy_>	Is the linux console really unresponsive when booting under hvm?
23:19	<kmacy_>	for you I mean
23:20	<kmacy_>	hvm boots 10x faster than qemu but its console is 100x less responsive
23:20	<kmacy_>	I have a theory that 0.6.1 use 32-bit file pointers
23:21	<kmacy_>	aliguori: you still there?
23:25	<aliguori>	kmacy_, yeah, sorry :-)
23:25	<aliguori>	what do you mean by "console"
23:25	<aliguori>	are you using vnc?
23:25	<aliguori>	libvncserver (which is what we use for vnc) sucks the big one
23:26	<kmacy_>	when I boot the linux test image from Maurice's site
23:26	<kmacy_>	the vga console
23:26	<aliguori>	s/Maurice/Fabrice/g
23:26	<aliguori>	yeah, are you using vnc or sdl?
23:26	<kmacy_>	you press return and it takes forever
23:26	<kmacy_>	yes
23:26	<kmacy_>	good question
23:27	<aliguori>	try using sdl
23:27	<aliguori>	it should be pretty responsive
23:27	<kmacy_>	ok I'll try that
23:27	<kmacy_>	qemu is much more responsive
23:27	<kmacy_>	but it boots much slower
23:27	<aliguori>	qemu is using sdl
23:27	<aliguori>	not vnc (unless you apply patches)
23:27	<kmacy_>	yes
23:36	<kmacy_>	have you seen anyone using a disk over 2GB with HVM?
23:37	<aliguori>	uh
23:37	<aliguori>	i'm not sure
23:37	<aliguori>	my images are probably 2GB
23:39	<kmacy_>	It occurred to me that that might be why 0.6.1 appears to install XP OK on my 3.3GB image but won't boot off of it
23:41	<kmacy_>	oh well
23:41	<kmacy_>	I guess I'll start on the PV guest sound driver tomorrow
23:41	<kmacy_>	I'll glance at Linux and FreeBSD to see which is easier
23:45	<aliguori>	kmacy_, did you try sdl?
23:47	<kmacy_>	it is still slightly slower than qemu, but it is actually usable
23:48	<kmacy_>	thanks
23:48	<kmacy_>	why is VNC the default?
23:49	<aliguori>	i dunno
23:49	<kmacy_>	even on a remote machine SDL is better
23:49	<kmacy_>	100Mbit at that
