<0> kernel should be backward compatible.
<1> That's what I just said.
<0> isn't always.
<0> holy monkey balls
<1> Anything that byp***es libc shouldn't be using the headers in /usr/include.
<0> it broke big time
<0> there's no include in the linux directory i pointed it at now..
<2> the headers are not necessarily backward compatible. in reality, userspace apps shouldn't be using kernel headers
<0> O_o
<2> the blessed thing to do is to copy the headers into the app and maintain them along with the app
<0> ok maybe this will work.
<0> woot, it worked
<0> i had to reinstall some kernel headers.
<0> also, now qemu can't seem to get a 1024Hz timer
<0> i am having difficulty with -smb option now
<0> it will connect to the local smbd on 10.0.2.4 but won't give me a share
<0> the default share name is qemu, yes? it doesn't seem to function
<3> Tefad: still having trouble?
<0> meh
<0> smb is so inefficient
<0> and then it locked up qemu
<0> i couldn't release my input devices.
<0> had to shell in and kill. then it still had my mouse
<0> had to run misc SDL program to get that back.
<0> yay windows.
<0> i'm going to install SFU's NFS client
<0> and hope that works better
<4> new to linux - wish to compile qemu - what is recommended distro?
<5> if you mean what distro compiles it best, none should have problems
<5> but you probably want a gcc-3.x set up
<6> mogguh
<4> thanks punk-***, i noticed though that a few I tried have gcc4 on it, what do i need to do to get rid of gcc4 and install gcc3.x?
<7> that's distro-specific
<7> but, why should gcc4 not work?
<3> sellenoff: different gcc installations can usually co-exist fine. be sure to p*** to qemu configure --cc=gcc-3.x once gcc 3 is installed.
<0> nice, qemu exploded
<0> lots of ff's
<3> it has something to do with how qemu relies on the structure of code output by gcc 3 (dyngen specifically).
<4> thanks dignome, i'll give it a try and see what happens.. just out of curiosity what distro do u use?
<3> debian stable (3.1)
<4> thanx
<4> what's the best place to ask questions on how i can extend/change qemu, such as emulating some different hardware?
<4> what i mean is - i want to emulate a pc that is using a ton of custom hardware. I've already reverse engineered the hardware, and just need to find the right places in qemu to change the code to handle it.
<4> of course, i could eventually figure it out, but not having looked at the qemu source yet, i'd prefer a point in the right direction.. ;)
<3> http://cvs.savannah.nongnu.org/viewcvs/?root=qemu ;p
<3> devs to talk in here quite often though so this is a good place to ask such things.
<3> not much dev activity during this time though.
<3> there is also qemu-devel list for qemu specific questions.
<3> s/to/do
<3> there are also the technical docs: http://fabrice.bellard.free.fr/qemu/tech-doc.html
<4> thanks.. i think i read the tech doc once, have to check it agian
<8> moin dignome
<3> lo iamlost
<9> howdy all
<9> trying to add kqemu as a device, manually it works fine(mknod /dev/kqemu;mknod /dev/kqemu c 250 0;chmpd 666). When I add kernel module to /etc/modules and following rule KERNEL="kqemu", NAME="%k" GROUP="kqemu", MODE="0660" (group exists) to /etc/udev/rules.d/... and reboot I still dont get the damn device generated. Any ideas?
<8> Chameleon22: you might have better luck asking in ur distro's channel (e.g. #gentoo)
<9> ubuntu, those guys know how to type ls (well majority)
<9> although, adding a dev should be the same i think on all distros
<1> Chameleon22: You shouldn't need the rule.
<1> If you're using udev just p*** major=0. I'm fairly sure that's documented.
<9> well doing slight tweaking now, see how i go.
<9> well rule should at least set correct permissions i suppose
<10> hi
<11> moin
<8> moin nox-
<11> moin iamlost
<12> QEMU RULEZ
<11> heh yeah :)
<8> moin aliguori

<2> howdy iamlost, nubuntu

<2> hey nox-
<0> i'm trying to partition a hard drive outside of qemu, using linux's fdisk
<0> it wants cylinders, how do i figure this out?
<11> try cfdisk
<0> no dice
<0> cannot get disk size
<11> hmm
<11> oh an qemu image?
<0> no, a raw image
<0> i was a dork and made a partition image
<0> then i realized i needed a disk image for it to work
<0> i'm trying to p*** 8G files back and forth
<0> so i'm doing ext2 loopback in linux, and ext2 driver for win2k
<0> i guess i could partition it in win2k
<0> then format it in linux
<13> cfdisk -z ... i think
<0> but i'd really like to know how to partition properly without relying on another OS doing it thinking the image is hardware
<0> no dice
<11> you could always use a linux livecd in qemu...
<13> cfdisk always worked on files, for me
<0> i started with a /dev/zero based image
<0> (dd if=/dev/zero of=image bs=1024 skip=$SIZE count=0)
<13> it seems you need to ***ign some number of cyulinders
<0> right
<0> i've got no idea where to pull that number from
<0> or which value is the one that qemu uses
<1> Tefad: Normal geometry (for large disks that use LBA at least) is 63 sectors, 16 heads
<1> And however many cylinders you need to get the size right.
<0> ok.
<0> what's the formula for that
<0> C*H*512 ?
<1> yes
<0> woot.
<0> rounded down of course
<0> sectors is pretty much ignored?
<1> Huh?
<0> my equation has no sector value
<1> Oh, no, I misread.
<0> ok.
<0> CHS*512?
<1> size = C*H*S*512
<0> ok doke.
<0> 20805 is what i get for 10GB
<0> hmm actually this will probably need to be larger.
<0> fdisk silly.
<0> try to reread partition table for changing a file instead of device
<12> has anyone compared the speed of the newest vmware vs qemu+kqemu for winxp?
<12> vmware player
<12> hacked for xp
<11> does the vmware license still forbid to publish benchmarks?
<12> who cares
<12> i know i dont
<11> :)
<2> nox-: it's a bit different now. they allow you to publish as long as you let them approve them first
<2> benchmarks@vmware.com i believe
<11> ah
<2> seems kind of silly to me :-)
<1> It's fairly normal.
<0> they don't want idiots to do it, then say vmware ****s
<0> because they had some unoptimized whozit involved
<2> actually, i'm pretty sure it's prevent comparision of different virtualization techniques
<2> for instance, paravirtualization to vmware-style rewritting
<12> well...any idiots know if its faster than kqemu? should i waste my time testing it tonight or not
<1> I'd be surprised if kqemu was faster.
<2> nubuntu, there is more to speed than just cpu virtualization. vmware almost certainly has better io and graphics drivers.
<12> yarly
<12> i think i believe that
<12> graphics are a lot of it
<12> but im on a 1.1ghz..and kqemu is fast for xp...would vmware stand a chance?
<1> nubuntu: Also, benchmarks are very subjective. If you care about speed then presumably you have some way of quantifying that speed try it and see. They're both available for no money.
<12> yeah, simcity 2000 is my benchmark
<0> ok, what's the algorithm for telling mount how far to skip before looking for data
<0> i'm trying to mount a partition inside a disk image
<14> # fdisk -lu yourimage.dd
<14> and look for the start of partition
<0> with proper -C -H -S p***ed in?
<14> or try # disktype yourimage.dd
Return to
#qemu
