How to get ubuntu server raw image

  • 772

I want ubuntu as VM in KVM with qcow2 format.

currently I can get the .iso format want can convert to the qcow2 format but this doesn't work.

so for this there cloud image with .img format and can be converted to the qcow2 format with qemu-img command and it works but the problem is that it has cloud-init which gives errors with the on-prem deployment in KVM

so, conclusion: qcow2 from .iso not working with KVM and qcow2 with .img is working but it has cloud init.

I want server ubuntu image with .img format with cloud-init.

server kvm

    after trying for the whole day, I found out there is no way to provision the Ubuntu VM in KVM with CLI virsh command even if you have perfect qcow2 image.

    because the ubuntu wants GUI input to otherwise it will be blocked

    and you cannot access the root ssh and virsh console without explicitly configuring for this

    the only solution is to take ubuntu server iso and use GUI to install and configure the Ubuntu with the above capability and copy the generated .qcow2 and form the basic virsh XML template and then use the copied .qcow2 image to provision the VM with the virsh command and get the console access.
