1 2 How to install and configure a QEMU mips64-linux installation. 3 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 4 5 Last updated 04 May 2015 6 7 This gives an apparently stable, but extremely slow, mips64-linux 8 install. It has the advantage that the idle loop works right and so 9 when the guest becomes idle, qemu uses only very little host cpu, so 10 you can leave the guest idling for long periods without bad 11 performance effects on the host. 12 13 More or less following 14 https://gmplib.org/~tege/qemu.html section 8 (for mips64) 15 16 Build qemu-2.2.1 with --target-list including mips64-softmmu 17 18 mkdir Mips64-1 19 cd Mips64-1 20 21 wget ftp://ftp.sunet.se/pub/Linux/distributions/debian/dists/wheezy/main/installer-mips/current/images/malta/netboot/vmlinux-3.2.0-4-4kc-malta 22 23 wget ftp://ftp.sunet.se/pub/Linux/distributions/debian/dists/wheezy/main/installer-mips/current/images/malta/netboot/initrd.gz 24 25 md5sum initrd.gz vmlinux-3.2.0-4-4kc-malta 26 71f05a4aaf24671fa72e903abd76a448 initrd.gz 27 307fc61d36cb370ea2b697d587af45a6 vmlinux-3.2.0-4-4kc-malta 28 29 # Note. 4G is easily enough to install debian and do a build of Valgrind. 30 # If you envisage needing more space, now is the time to choose a larger 31 # number. 32 33 /path/to/Qemu221/bin/qemu-img create disk4G.img 4G 34 35 /path/to/Qemu221/bin/qemu-system-mips64 \ 36 -M malta -cpu 5Kc -m 256 -hda disk4G.img \ 37 -net nic,macaddr=52:54:00:fa:ce:08 -net user,hostfwd=tcp::5555-:22 \ 38 -kernel vmlinux-3.2.0-4-4kc-malta -initrd initrd.img-3.2.0-4-4kc-malta \ 39 -append "root=/dev/sda1 console=ttyS0 --" -nographic 40 41 Do an install, be as vanilla as possible, allow it to create a user 42 "username", and do not ask it to install any extra software. But, 43 when you get to here 44 45 [!!] Finish the installation 46 47 Installation complete 48 Installation is complete, so it is time to boot into your new system. 49 Make sure to remove the installation media (CD-ROM, floppies), so 50 that you boot into the new system rather than restarting the 51 installation. 52 53 <Go Back> <Continue> 54 55 56 57 do "Go Back" 58 then in the next menu "Execute a shell", "Continue" 59 60 This gives you a root shell in the new VM. In that shell: 61 62 mount -t proc proc /target/proc 63 mount --rbind /sys /target/sys 64 mount --rbind /dev /target/dev 65 chroot /target bash 66 /etc/init.d/ssh start 67 ls /boot 68 System.map-3.2.0-4-5kc-malta initrd.img-3.2.0-4-5kc-malta 69 config-3.2.0-4-5kc-malta vmlinux-3.2.0-4-5kc-malta 70 71 Then on the host, copy out the vmlinux and initrd: 72 73 ssh -p 5555 username@localhost \ 74 "tar -c -f - --exclude=lost+found /boot" | tar xf - 75 76 exit 77 exit 78 Select "Finish the installation" 79 Continue 80 81 When it reboots, kill qemu from another shell, else it will try to reinstall. 82 83 Now start the installation: 84 85 /path/to/Qemu221/bin/qemu-system-mips64 \ 86 -M malta -cpu 5Kc -m 256 -hda disk4G.img -net nic,macaddr=52:54:00:fa:ce:08 \ 87 -net user,hostfwd=tcp::5555-:22 -kernel boot/vmlinux-3.2.0-4-5kc-malta \ 88 -initrd boot/initrd.img-3.2.0-4-5kc-malta \ 89 -append "root=/dev/sda1 console=ttyS0" -nographic 90 91 System seems to have 256MB memory no matter how much you request. 92 93 This is basically a 32 bit system at this point. To get something 94 that can build 64 bit executables, it is necessary to install 95 gcc-multilib and g++-multilib. 96 97 Now you can ssh into the VM and install stuff as usual: 98 99 ssh -XC -p 5555 username@localhost 100 101 (on the guest) 102 become root 103 104 apt-get install make g++ gcc subversion emacs gdb automake autoconf 105 apt-get gcc-multilib g++-multilib 106 107 Configuring V on the guest: 108 109 ./autogen.sh 110 CFLAGS="-mips64 -mabi=64" CXXFLAGS="-mips64 -mabi=64" \ 111 ./configure --prefix=`pwd`/Inst 112
