grub-install step failed due to this naming which is different with the other template (in there sda)...

Drop the specific vbox vbguest install step (no need here ¯\_(ツ)_/¯)

heads up @vlorentz (since you raise the license remark) @olasd (since you raised the question about vbox) @vsellier (since you are the original author ;)

template build process worked, that's a start, i guess.

up to line 9, that's the main differing part from the original template from D4136

(well that and the /dev/vda bootloader install instruction below and the qcow2 format at the end.)

33

explicitely /dev/sda is replaced by /dev/vda

68

.qcow2 format is different than the .box

That's huge. I'm guessing that does thin provisioning (i.e. it's not allocating 20 GB worth of zeroes)?

No idea, really. I started from the other vbox template which defined it as well.
I'll check.

[1] does not convey much information

I'll decrease to say 5G, hoping that's sufficient for the template build to pass.

  • Decrease disk_size to 5G
  • template build still ok (P800 updated)

so i should have realized earlier, as @vsellier made me notice the finalized template is about ~500Mib.
So it's not indeed allocating the 20Gb worth of zeroes.

And my tryout of a deposit-staging with a 5Gb disk is not enough space.
So i'll readapt this.
(Most possibly in another diff though, to avoid the rebase dance a bit, if you don't mind ;).

Thanks, it's really great.
I have tested locally the qemutest vm and converted the staging-webapp and staging-deposit vms, everything looks good.
The virtualbox and libvirt networks (with the same ip range) can't cohabit together but after a cleanup on the virtualbox side, everything works as expected.

The vm management itself (up / destroy / status) is really smooth compared to the virtualbox provider.

As discuss, I'm ok to completely remove the virtualbox usage to focus on only one provider.
