Generic virtual machine target. This is particularly useful when doing development and testing.
Installation
https://maedevu.maemo.org/images/virtual-machines/
There are three different types of images: VirtualBox (.box), QEMU (.qcow2, .vdi) and Vagrant. The VirtualBox image may be converted to a VMware VMDK image which has been reported to perform better and have good hardware acceleration. Converting the qcow2 image to raw allows it to be used on real hardware.
VirtualBox
Download latest .vdi.xz image, unpack it with "xz -d" command. Create new Virtual Machine, select "Debian (64-bit)" and 1024MB RAM. Use the downloaded file as virtual hard disk. You are done!
QEMU
In general something like
qemu-system-x86_64 -hda maemo-leste-1.0-amd64.qcow2 -enable-kvm -cpu host -smp cores=2 -m 1024
should work. But there seem to be issues with some QEMU versions, for more details see issue#198.
To set up a port forward for SSH, add:
-nic user,hostfwd=tcp:127.0.0.1:7722-:22
And then log in like this (password: toor):
ssh root@localhost -p 7722
If the mouse pointer is grabbed and no cursor shows, you can add
-usb -device usb-tablet
to the command line
If you have a USB modem you can also use that in QEMU. You can either use sudo to elevate your privileges to be able to use it:
sudo qemu-system-x86_64 -hda maemo-leste-1.0-amd64-virtual-20200324.qcow2 -enable-kvm -cpu host -smp cores=2 -m 1024 \ -nic user,hostfwd=tcp:127.0.0.1:7722-:22 \ -usb -device usb-ehci,id=ehci \ -device usb-host,bus=ehci.0,vendorid=0x0bdb,productid=0x193e
Or you can make a udev rule for your device. For example, with a Lenovo Ericsson N5321 gw you can create "/etc/udev/rules.d/45-n5321.rules" with this in it:
# Lenovo Ericsson N5321 gw simple udev rule
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0bdb", ATTRS{idProduct}=="193e", \
MODE:="0666"
And then activate it by running these two commands as root:
# udevadm control --reload-rules # udevadm trigger
Now you can run QEMU without the need for sudo!
Initial configuration
On the first run you may want to generate ssh host keys and set the timezone. To do so open the "X Terminal" application and run:
sudo su - dpkg-reconfigure openssh-server dpkg-reconfigure tzdata
Make the system up-to-date:
apt update apt upgrade apt install linux-image-amd64 reboot
To get networking to work (at least in virtualbox), launch a shell and do
sudo ifconfig eth0 up sudo dhclient eth0
