Here is the recipe for my first successful build and run through to an error... StackVM.unikernel: could not find any display driver This is done under 32-bit Debian 8 Jessie. Attached is StackRumpXenUnikernelConfig.st # Built the Rumprun Platform $ mkdir -p cogunikernel $ git clone http://repo.rumpkernel.org/rumprun $ cd rumprun $ git submodule update --init $ CC=cc ./build-rr.sh xen >> toolchain tuple: i486-rumprun-netbsdelf >> cc wrapper: i486-rumprun-netbsdelf-gcc >> installed to "/home/ben/Repos/cogunikernel/rumprun/./rumprun" # Generated Cog VM sources $ cd ../../cogunikernel $ git clone https://github.com/pharo-project/pharo-vm.git $ cd pharo-vm/image $ ./newImage.sh $ ./pharo-ui generator.image Tools > File Browser Filed in StackRumpXenUnikernelConfig.st From class comment, evaluated... StackRumpXenUnikernelConfig new generateSources; generate. # Built the StackVM and StackVM.unikernel $ bash build.sh # Tested them... $ cd ../results $ ./StackVM > bash: ./StackVM: cannot execute binary file: Exec format error Good. That was the expected result. $ rumprun xen -i StackVM.unikernel > StackVM.unikernel: could not find any display driver # Stop unikernel machine running, from another terminal... $ xl list $ xl destroy rumprun-StackVM.unikernel ================ Now I basically just poked, cut and slashed the config until it could compile and boot up the unikernel, without regard for what that may break. Making the VM *actually* work is bigger step that for now is beyond me, but I'll have a bite at it. Really my motivation in doing this after I stumbled on the rumprun tutorial, was I wanted to crack the seal on it to interest others capable :). I'd be interested if the above recipe is successful for others. Todo: * incorporate rumprun as an auto-built third party library, rather than outside, perhaps using git submodule like the rump kernel already does (if these can be nested) * determine how to deal with different rumprun toolchains (depending on which platform the target) * move the baking step from the build script to the generated CMake configuration * determine how to deal with lack of display * determine how an image file might be passed to the VM - maybe baking the VM and image into a ram disk (?) cheers -ben |

There were a couple of minor log errors below, so I attach a script that does it all, tested on 32-bit Debian Jessie. cheers -ben On Sat, Dec 12, 2015 at 2:57 PM, Ben Coman <[hidden email]> wrote: > Here is the recipe for my first successful build and run through to an error... > StackVM.unikernel: could not find any display driver > > This is done under 32-bit Debian 8 Jessie. > Attached is StackRumpXenUnikernelConfig.st > > # Built the Rumprun Platform > > $ mkdir -p cogunikernel > $ git clone http://repo.rumpkernel.org/rumprun > $ cd rumprun > $ git submodule update --init > $ CC=cc ./build-rr.sh xen >>> toolchain tuple: i486-rumprun-netbsdelf >>> cc wrapper: i486-rumprun-netbsdelf-gcc >>> installed to "/home/ben/Repos/cogunikernel/rumprun/./rumprun" > > > # Generated Cog VM sources > > $ cd ../../cogunikernel > $ git clone https://github.com/pharo-project/pharo-vm.git > $ cd pharo-vm/image > $ ./newImage.sh > $ ./pharo-ui generator.image > Tools > File Browser > Filed in StackRumpXenUnikernelConfig.st > From class comment, evaluated... > StackRumpXenUnikernelConfig new > generateSources; generate. > > > # Built the StackVM and StackVM.unikernel > > $ bash build.sh > > > # Tested them... > > $ cd ../results > $ ./StackVM > > bash: ./StackVM: cannot execute binary file: Exec format error > Good.
