This bug is awaiting verification that the linux-kvm/5.4.0-1051.53 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

The problem is that VM booted from that image don't subscribes properly to the IGMP multicast group thus test is failing. All works fine when image https://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64.img is used in the same test. The problem is that in the minimal image kernel linux-image-kvm (vs. linux-image-generic in the "regular" cloud image) and that "-kvm" image has disabled MULTICAST: # CONFIG_IP_MULTICAST is not set Would it be maybe possible to enable this option in the kernel used in the "minimal" cloud images?
