debvm 0.3 autopkgtest fails: Copying files into the device: __populate_fs: Could not allocate block in ext2 filesystem while writing file

[Benjamin Drung]

The autopkgtest fails:

```
Copying files into the device: __populate_fs: Could not allocate block in ext2 filesystem while writing file "ftpmaster.internal_ubuntu_dists_oracular_universe_source_Sources"
mkfs.ext4: Could not allocate block in ext2 filesystem while populating file system
```

Full log: https://autopkgtest.ubuntu.com/results/autopkgtest-oracular/oracular/amd64/d/debvm/20240503_075137_28b17@/log.gz

This can be fixed by increasing the image size from 1G to 2G.

Installed-Size:

linux-firmware: 473705
linux-image-6.8.0-31-generic: 14604
linux-modules-extra-6.8.0-31-generic: 109988

These three packages already consume 598,297 KB. So I suggest to increase the default size to 2G.

[Benjamin Drung (bdrung)]

An alternative is to avoid installing the linux-firmware and linux-modules-extra on Ubuntu.

This bug was fixed in the package debvm - 0.3ubuntu1

---------------
debvm (0.3ubuntu1) oracular; urgency=medium

  * tests/create-and-run.sh: Increase timeout by 300 seconds (for ppc64el)
    (LP: #2046544)
  * debvm-create: Increase default VM size to 2G (LP: #2064921)
