Bug Description

For Ubuntu 23.04:

* I created a VM in virt-manager with 0,0 GiB (the unit used by virt-manager, only one decimal is allowed -- but this is not related to this filed issue) to find out about the required disk space. Ubiquity says that it requires 18 GB
* Created a new VM in virt-manager with 16,8 GiB (18.03886 GB). Tried to re-install. Uqiquity: "Not enought disk space to install Ubuntu. Required: 18 GB. Available: 17: GB"
* Created a new VM in virt-manager with 17,7 GiB (19.00523 GB). Tried to re-install. Uqiquity: "Not enought disk space to install Ubuntu. Required: 18 GB. Available: 18: GB"
* Created a new VM in virt-manager with 18,4 GiB (19.75685 GB). Tried to re-install. Uqiquity: "Not enought disk space to install Ubuntu. Required: 18 GB. Available: 18: GB"
* Created a new VM in virt-manager with 18,5 GiB (19.86423 GB). Tried to re-install. Uqiquity: No complaint, I could install the distro.

Also, please add a decimal to the required disk space even for whole numbers ("19.9" in this case) to make it convenient to evaluate it.

I tested this myself as you set out, and it did indeed fail with 16.8GiB. However when I bumped the storage up to 17.7GiB, it succeeded. Do you have any more details on reproducing this I might be missing?

Another thing to add - using virt-install instead of virt-manager, I created a storage disk with 16.8GiB, and I did not get the "not enough space" error as described above.

```
qemu-img create -f qcow2 image.qcow2 16.8G
Formatting 'image.qcow2', fmt=qcow2 cluster_size=65536 extended_l2=off compression_type=zlib size=18038862643 lazy_refcounts=off refcount_bits=16
```

```
virt-install --os-variant ubuntu23.10 --name myvm --memory 2048 --disk image.qcow2 --cdrom mantic-desktop-amd64.iso
```

Additionally, these screenshots are of the new desktop installer, which runs Subiquity, not Ubiquity. Just checking as I've also been testing with the new desktop installer!

Thank you for your report.

I used Ubuntu 23.04, so your release, mantic-desktop-amd64.iso (Ubuntu 23.10) is ahead of mine. Perhaps this has been fixed?

As stated, this is the new ubuntu-desktop-installer, it is not ubiquity. Assigning back to the correct project.
