<0> can someone point me to a way to initialize a qemu-img without running a linux install on it? I know it can be done but how?
<1> can it?
<1> i'd run qemu -cdrom debian-installer.iso -hda hda.img -boot d
<1> or somesuch
<0> rpath rbuilder does this online.
<1> wouldn't really know another way
<2> lbrigman: what do you mean by initializing it?
<0> I would like the partition table setup for booting and place an ext2 filesystem on the file and then populated that filesystem.
<0> If I can get the first two done. Mounting it and populating it are not a problem.
<3> kind of like debootstrap?
<4> lbrigman: creating the partition table can be done with fdisk
<0> Palats:fdisk will work on a file from a script?
<0> dignome: I don't know what debootstrap is.
<4> I dunno waht you mean in "from a script" but fdisk works fine on a file, yep
<4> deboostrap populate the filesystem with a miniam debian system
<2> lbrigman: fdisk does not care if you feed it a file
<4> In fact, if this is for a simple linux setup, you don't really have to create a full blown disk with partition table and so on, you can just use a bare filesystem in a file (and use something like root=/dev/hda)
<0> Will that work for qemu? Does the booting linux expect a partition table in qemu?
<4> nop; the easiest way to do that is to specify your kernel thourgh -kernel option
<0> I don't have to have the kernel in the image. Actually I don't want the kernel in the image
<4> so, if you don't need multiple partition in your system, bare partition is the easiest way to go
<0> And qemu doesn't care what the file looks like? Example: cramfs or squashfs on bare partition? As long as the kernel understands how to read (and possible write it).
<4> qemu presents a bare disk to the system, it doesn't care about what's writed on
<2> I have strange segfault with ps using guest installed recent opensuse factory
<2> guiest opcode starts with 0f 1f ...
<0> Palats: thanks, I'll give it a try.
<2> what is hinting nops? does qemu support them?
<0> Palats: Tried it. It works with what I have. Thanks again.
<4> :)
<2> heh seems like this is a problem with x86 translate
<2> prefetch 1f 08 cases 0...3 are handled normally, 4...7 are illegal ops - that should be nops instead
<2> and 0f 1f are multibyte nops; seems like these are now generated with gcc-4.1.1
<2> which explains my problems with ps in opensuse factory/qemu
<2> 0f 1f are illegal ops for qemu AFAICS
<2> valgrind rulez volumes :) I'm able to execute ps with valgrind :D
<2> pbrook: will new translator be able to understand these multibyte nops?
<5> The insn decoding is exactly the same.
<2> since qemu pretends to support 686, these nops are somewhat required
<5> My copy of the ia32 sdm says they're undefined.
<5> Err, I mean unspecified.
<2> yet they are in gcc
<5> I think you mean gas.
<2> yes
<5> Sounds like a gas bug.
<2> I bet there is a small footnote to treat these insns as nops
<2> what made me think about footnote: http://softwareforums.intel.com/ISN/Community/en-US/forums/thread/980709.aspx
<2> oh well, the last message suggests an NDA
<5> The amd64 architecture docs specify them as nops. I've yet to find anything conclusive in teh intel docs.
<2> pbrook: do you use NDA material? :)
<5> All my x86 documentation is publicly available.
<5> I agree qemu should implement them as nops though.
<5> I'm just trying to figure out whether Intel screwed up the documentation. They probably did.
<2> now a real work for fabrice :)
<5> It's fairly trivial to fix.
<2> i see one just decode the two-byte insn 0f 1f and ignore it, right?
<2> otherwise older processors are screwed (they work in real life)
<5> Aha! "All blanks in the opcode map shown in table A-3 are reserved and should not be used. Do not depend on teh operation of these undefined or reserved opcodes". And the entry in Table A-3 for 0f 1f is blank.
<6> pbrook: in the current docs it's listed as NOP
<2> heh
<6> "NOP Ev" to be precise
<6> and page 4-4 of volume 2b (description of NOP) lists them too, "0f 1F/0 NOP r/m16 ... " and "0f 1F/0 NOP r/m32 ... "
<6> it also has a table of "recommended multi-byte sequence of NOP instruction" on that page
<5> My docs are from dated 2004. They were released after the Pentuim4.
<6> intel just updated these a few months ago
<2> now, anyone to prepare the patch? :)
<6> my copy is from March 2006
<5> garrison: Does gas generate these nops with -march=i586?
<2> pbrook: can't check now, but opensuse is built for i586
<2> pbrook: and qemu pretend i686, so why?
<5> garrison: Technically thet aren't defined for i686.
<5> Most likely someone decided that all intel cpus happen to implement them as nops so they're going to use them anyway.
<2> :)
<2> ok, I'll now let yast to ruin my opensuse factory installation in qemu, for I know how to fix it tomorrow :)
<7> anyone heres compiles qemu with GCC4
<7> ?
<2> TLF: me (but op.c with gcc-3.4.6)
<7> garrison: why?
<2> because it's in a faq
<7> mmm, what fAQ?
<2> dyngen is easily confused
<8> hmm
<9> hello all
<9> i just bought a LEGAL copy of windows XP and im trying to install it into qemu, no luck, always fails on a CRC error trying to copy SXP.DLL file, any ideas as to whats going on?
<3> qemu version? what is the command line used?
<9> im not using the kernel module
<9> qemu -m 128 -kernel-kqemu -boot d -no-acpi -std-vga -win2k-hack -cdrom /dev/cdrom winxp.img
<9> qemu 0.8,2-1
<9> qemu 0.8.2-1
<9> its a brand new spanish copy of windows xp service pack 2
<3> right - so how do you know kqemu is not being used?
<3> does it say something like "acceleration layer not activated on console"
<3> erm "QEMU acceleration layer not activated" on console
<9> QEMU acceleration layer not activated
<9> i dont load the module
<9> as i understand: to install DONT use kqemu, and when installed use if you want to
<3> ok. for one -win2k-hack is only necessary for windows 2000 install.
<3> right, -kernel-kqemu can't be used for the install as of yet. user accel. is fine.
<9> dignome, ive tried without the -win2k-hack... just wanted to see if it would change any
<9> result is the same
<8> my win2k3ss installation has been sat at 'Installing Windows' 39mins remain for ages :/
<8> I like how it's still scrolling through its billboards :)
<3> samuel: ok. so either it is a qemu bug or a problem with your install media.
<9> dignome, ive gone back to the store to change the disk, same result
<9> same result also with vmware
<9> when i try to access the files it seems to want my cdrom drive seeks forever
<9> from linux
<3> ok. maybe the physical cdrom drive is to blame
<9> is this some sort of fu$%^& up DRM?
<9> or the cdrom
<3> does microsoft drm their cds?
<9> dunno, im asking
<9> dont see why with "product activation"
<10> maybe try making an image file out of it? will be faster anyway
<9> joga, same problem with using gnomebaker, cant seem to seek that point
<9> ill try nero
<10> hmm filthy cd hopefully..
<9> whats the legality of downloading a copy of windows xp from gnutella?
<10> illegal, I guess
<9> ive a valid legal copy, can i get an image?
<10> though, you *did* pay for it
<10> well, I don't know, guess it depends on the legislation of the country you're in :p
<9> wouldnt it fall under "fair use"?
<10> I'd say it's fair use but microsoft may have a different opinion
<10> or your isp, or whoever..
<11> i think that is right for the law to have a copy for personal use but
<11> it's not fair for ms license
<9> well i dont care, as far as i can tell its fair use, im only using one copy and no more... ill try that and then activating it with the licence i got from the box
<10> does gnutella distribute bandwidth so downloading it would help other, non-legitimate users to download it faster? ;)
<5> samuel: The answer to your question almost certainly depends where you live, and who you ask. I doubt there's anyone qualified to answer your question on this channel.
<10> ask microsoft, heh
<9> pbrook, fair enough...
<9> im installing again, in a second ill paste the exact error
<10> samuel have you simply tried cat /dev/cdrom > winxp.iso ?
<10> or dd
<9> joga, dd failed
<9> didnt try cat
<10> does dmesg show anything peculiar?
<11> samuel: i had a laptop with a regular ms license
<11> when i formatted i used a copy of a cd
<11> iand used my serial
<9> THATS what pisses me off too... i threw away my CD!!!
<11> it didn't work too
<11> s/iand/and i
<9> is qemu with kqemu comparable to vmware?
<10> samuel not as fast but a lot better
<9> joga, i like that net and sound works out of the box
<9> no problems
<9> do i need to use the -win2k-hack to install windows 2000?
<3> just for the install
