Ubuntu Core on SUSE

WARNING!

Ubuntu requires mandatory "store account" - even for testing - once you boot image for the 1st time there will appear:

==================...
Profile setup
==================...
Enter an email address from your account in the store.                      
                                                                              
Email address:                                                              
                If you do not have an account, visit                        
                 https://login.ubuntu.com to create one.

Therefore I abandoned evaluation of this product. Sorry...

I was curios what is Ubuntu Core for so I visited these 2 pages to try it:

However SUSE LEAP has no /usr/share/OVMF/OVMF_CODE.secboot.fd nor /usr/share/OVMF/OVMF_VARS.ms.fd

On SUSE we need to install this most close package:

  • sudo zypper in qemu-ovmf-x86_64
  • now put image to some read-write directory
  • additionally copy to that directory: 
    cp /usr/share/qemu/ovmf-x86_64-smm-code.bin .
cp /usr/share/qemu/ovmf-x86_64-smm-vars.bin .
  • at least -vars.bin must be read-write because UEFI modify its (it is like non-volatile memory)

Before running QEMU you should be sure that you can access /dev/kvm device (normally group kvm required). If you want to setup only "on demand" access you can:

  • as root run gpasswd kvm to set Group(!) password for kvm group access
  • as normal user than use newgrp kvm and specify above password to get kvm group access
  • use command groups to verify that you are really now in kvm group

Here is final QEMU command I tried:

qemu-system-x86_64 \
 -enable-kvm \
 -smp 1 \
 -m 2048 \
 -machine q35 \
 -cpu host \
 -global ICH9-LPC.disable_s3=1 \
 -net nic,model=virtio \
 -net user,hostfwd=tcp::8022-:22,hostfwd=tcp::8090-:80  \
 -drive file=ovmf-x86_64-smm-code.bin,if=pflash,format=raw,unit=0,readonly=on \
 -drive file=ovmf-x86_64-smm-vars.bin,if=pflash,format=raw,unit=1 \
 -drive file=ubuntu-core-24-amd64.img,if=none,format=raw,id=disk1 \
 -device virtio-blk-pci,drive=disk1,bootindex=1 \
 -serial mon:stdio
