“initramfs unpacking failed: write error” due to stupid typo in virsh-install

i’ve been trying to set up a new vm using:

virt-install --name manticore1.test --vcpus 4 --ram 128 --disk /mnt/kvm/manticore1.test/vda.qcow2,bus=virtio -c /mnt/iso/firmware-11.0.0-amd64-netinst.iso --noautoconsole --accelerate --network=bridge:br0,model=virtio --graphics vnc --os-type linux

trying and trying, and each time i got the same boot failure:

Initramfs unpacking failed: write error

root cause? allocating 128MB instead of intended 128GB of RAM for the VM. hopefully this post helps some poor soul who runs into a similar issue.
