[kernel v6.2 regression, affects Ubuntu 23.04 and Fedora 38] limactl start --set '.vmType = "vz"' crashes: "usernet unable to resolve IP for SSH forwarding" #1577
Description
EDIT
This seems to be a regression in kernel 6.2, reported to https://bugzilla.kernel.org/show_bug.cgi?id=217485 .
kernel 6.3 seems to be bootable (via GRUB).
- Report to kernel bugzilla https://bugzilla.kernel.org/show_bug.cgi?id=217485
- Report to LKML https://lkml.org/lkml/2023/5/27/252
- Report to Apple to fix Virtualization.framework (reported via https://www.apple.com/feedback/macos.html , but no bug ticket is available)
- Report to Ubuntu to cherrypick torvalds/linux@8e41e0a into Ubuntu 23.04 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2021403
- Wait for Ubuntu to cherrypick torvalds/linux@8e41e0a
- Report to Fedora to cherrypick torvalds/linux@8e41e0a into Fedora 38 (Fedora usually do not update qcow2 images, so probably we should just wait for Fedora 39, which is likely to use kernel >= 6.3)
- Wait for Fedora to cherrypick torvalds/linux@8e41e0a

template://experimental/vz still works.
(Slightly off-topic: a patch for loading kernel >= 6.2 using VZLinuxBootLoader, without GRUB)
- Submitted a kernel patch https://lore.kernel.org/linux-efi/CAG8fp8Te=oT1JJhTpOZvgWJrgcTq2DXan8UOVZ=KYCYNa8cKog@mail.gmail.com/
- Wait for the kernel patch to be merged: torvalds/linux@36e4fc5 (commit message was modified and slightly inaccurate)
