We have updated our distribution images and netboot installers with new releases and two new additions. Here is a list of what is new.
- Ubuntu Bionic Beaver 18.04
- Fedora 28
- Alpine Linux 3.7 (HVM netboot installer only)
- NixOS 18.03 (HVM netboot installer only)
If you decide to install Ubuntu Bionic, we’ve made a couple of changes
to the default install. The distribution originally shipped with
systemd-networkd and systemd-resolved, used for network management
and name resolution, respectively. We have disabled them both
in our image. Network interfaces are instead configured with the
widely-known ifupdown method used in several other distros we support,
and resolvconf is used for managing the
We’ve added two new netboot installers due to customer request: Alpine Linux 3.7 and NixOS 18.03. These two are only available for guests with HVM virtualization. If you have an HVM guest, you can find them in the Linux netboot installers submenu from the set bootloader or rescue mode menu of the management console.
We have removed Debian Wheezy from this release, as it is now end-of-life.
We have switched back to the stock CentOS 7 kernel. For a few months, we used the CentOS Plus kernel in our CentOS 7 releases, because the stock kernel would not boot for a paravirtualized guest. The kernel bug that caused the stock kernel not to boot is fixed as of CentOS 7.5, so we have gone back to using it in our releases.
For Debian-based distributions, CentOS 7, and Fedora, we have updated our sshd configuration. By default, sshd now generates ED25519 and ECDSA host keys, as well as the RSA host key. We’ve also updated the lists of ciphers, MACs, and key exchange algorithms to support and favor newer algorithms.
These distribution images and netboot installers are available from the management console.
