Ok , I do have a qemu-system-i386 : address@hidden
/ $ qemu-system-i386 --version
My intention is to run an old application , that used to run on
FedoraCore2,also a modified version of the app runs on Centos
5.1/6.3 also Fedora 14 .QEMU emulator version 1.1.2 (Debian 1.1.2+dfsg-6a), Copyright (c) 2003-2008 Fabrice Bellard The problem lies with glibc. The glibc in newer kernels , is backwards compatible up to a certain point, but not far enough. The version I require is GLIBC.2.0 also, the app never ran on debian , always fedora/Red hat and Centos , hence the emulation of i386 on ARM. So it requires ld-linux.so.2 , libc.so.6 and so on. The RPM Package for glibc-2.12.90-1mgc25.i686.rpm , is the package for fc14. - in the /lib directory of FC14 : address@hidden lib]# ls -al libc.so.6 lrwxrwxrwx. 1 root root 15 Oct 22 2010 libc.so.6 -> libc-2.12.90.so Now there are only a few of these libraries, like /lib/ld-linux.so.2 /lib/libm.so.6 that are needed to run. Do you mean there's a possibility that I'd be able to run the libraries, via the qemu-i386 and manage to get the app working? Also should i try and use qemu-system-i386 and try it the same way I did with only qemu? I have a Model B pi, 512 MB RAM ,Disk space : rootfs 3.6G 2.0G 1.5G 57% / (the puppy iso is 130 MB , the centos one is +- 300 ) This should suffice right ? Thank you so much for your response Regards Hi, Am 04.04.2013 13:06, schrieb Benito:I know this might absurd, but I'm trying to run a 32-bit guest on a Raspberry Pi - Raspbian OS - Debian Wheezy ARM I have used : qemu-img create -f raw harddrive.raw 700M qemu -hda harddrive.raw -cdrom fedora14.iso I've installed qemu via apt-get install qemu on the Pi.You're not providing sufficient details for the upstream community to help you, so CC'ing the Debian maintainer. "qemu" sounds rather old, it's qemu-system-i386 since several versions already. Did you check that you have sufficient RAM on your Raspi? Or disk space on your SD card / USB disk? Disk images are created sparse, and when the host runs out of resources lots of things can happen.After I do the 2nd command, the guest os starts up , but soon consumes 100% cpu , and then hangs. Tried with puppy 511 , centos6.3 minimal , fedora14 Is there a way to run any of these in "invisible" mode or user mode , and get past this obstacle.. ?qemu-i386 can execute individual Linux binaries, with a bunch of known issues. Might or might not work for you - you don't say what you actually want to do.Can I create this guest on a faster machine , and clone itto the Pi's qemu that runs ARM ?Yes. The disk image is just a file. Regards, AndreasAlso am I missing something regarding the creation of the guest? I don't need a GUI for the guest, just need to be able to get to it and execute commands. Please could someone point me in the right direction ? Kind Regards Benito |
