Fix fallocate issue on cloud-init 19.4 for Fedora 33 cloud images
by Federico Ressi 27 Apr '21

27 Apr '21

Hello all, I am writing to this list because I found out F33 cloud image cloud init support for creating swap files looks to be broken probably because of a known Linux 5.7+ kernel issue [1]. The problem is cloud-init is trying to create a new swap file by using fallocate command that is not working well (kernel is complaining the file has holes when executing swapon command just later). The easy workaround for this issue is to use dd command instead of fallocate command in cloud-init. Because I don't know the whole procedure required for submitting a patch I am writing to you in the hope you can help me in having the F33 cloud image fixed. Please find attached to this e-mail the simple fix for cloud init 19.4 I just wrote. The patch should apply the procedure documented in Fedora docs [2] Thank you in advance.

systemd update breaks DNS resolution on Fedora 33 cloud instances
by Tadej Janež 19 Apr '21

19 Apr '21

Hi all! I was recently hit by this and it took me some time to figure out what was going on. I provisioned a fresh Fedora 33 cloud instance on DigitalOcean. After completing the initial upgrade via 'dnf update' and rebooting the system, DNS resolution stopped working. I did a little debugging and saw that no DNS servers were configured: $ resolvectl dns Global: Link 2 (eth0): Link 3 (eth1): $ resolvectl status Global Protocols: LLMNR=resolve -mDNS -DNSOverTLS DNSSEC=no/unsupported resolv.conf mode: stub Link 2 (eth0) Current Scopes: LLMNR/IPv4 LLMNR/IPv6 Protocols: -DefaultRoute +LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported Link 3 (eth1) I was confused how could that happen since running 'dnf update' on the first boot clearly required DNS resolution to work. It turns out a recent systemd update, namely systemd-246.7-2.fc33 (https://bodhi.fedoraproject.org/updates/FEDORA-2020-3616681a70) includes this commit: https://src.fedoraproject.org/rpms/systemd/c/ed795fb1fc9a2c20ebcac34bdf7e7c… which removes the fallback DNS server list (i.e. Cloudflare's and/or Google's DNS servers) due to concerns over DNS requests being personally identifying information (PII) in the sense of GDPR? In combination with NetworkManager's DNS server handling being disabled via cloud-init: $ cat /etc/NetworkManager/conf.d/99-cloud-init.conf # Created by cloud-init on instance boot automatically, do not edit. # [main] dns = none this results in no DNS servers being configured on the system. The consequence is that Fedora 33 cloud instances are broken after updating the systemd package to version 246.7-2.fc33. (I haven't checked but if Fedora 34 cloud images include this version of systemd, then DNS resolution won't work even on first boot.) Please advise on the best steps to fix this issue. Regards, Tadej

Hey All, We are running a Fedora Linux 34 Cloud Test Day from Friday, April 16 through Monday, April 19. As a part of this test day[0] we will be testing the Fedora Cloud Images. You can test the regular base image using testcloud or if you have an Amazon account, you can test the AMIs listed on the wiki. The results page[1], has the test cases which are basic and must pass. As usual, we will be around #fedora-test-day over freenode for any questions!
