-- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1873809 Title: Make linux-kvm bootable in LXD VMs Status in cloud-images: Invalid Status in linux-kvm package in Ubuntu: Triaged Status in linux-kvm source package in Focal: Fix Committed Bug description: The `disk-kvm.img` images which are to be preferred when run under virtualization, currently completely fail to boot under UEFI. A workaround was put in place such that LXD instead will pull generic- based images until this is resolved, this however does come with a much longer boot time (as the kernel panics, reboots and then boots) and also reduced functionality from cloud-init, so we'd still like this fixed in the near future. To get things behaving, it looks like we need the following config options to be enable in linux-kvm: - CONFIG_EFI_STUB - CONFIG_VSOCKETS - CONFIG_VIRTIO_VSOCKETS - CONFIG_VIRTIO_VSOCKETS_COMMON == Rationale == We'd like to be able to use the linux-kvm based images for LXD, those will directly boot without needing the panic+reboot behavior of generic images and will be much lighter in general. We also need the LXD agent to work, which requires functional virtio vsock. == Test case == - wget http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-lxd.tar.xz - wget http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img - lxc image import focal-server-cloudimg-amd64-lxd.tar.xz focal-server-cloudimg-amd64-disk-kvm.img --alias bug1873809 - lxc launch bug1873809 v1 - lxc console v1 - <check that it boots to login prompt> - <disconnect with ctrl+a-q> - lxc exec v1 bash To validate a new kernel, you'll need to manually repack the .img file and install the new kernel in there. == Regression potential == I don't know who else is using those kvm images right now, but those changes will cause a change to the kernel binary such that it contains the EFI stub bits + a signature. This could cause some (horribly broken) systems to no longer be able to boot that kernel. Though considering that such a setup is common to our other kernels, this seems unlikely. Also, this will be introducing virtio vsock support which again, could maybe confused some horribly broken systems? In either case, the kernel conveniently is the only package which ships multiple versions concurently, so rebooting on the previous kernel is always an option, mitigating some of the risks. -- Details from original report -- User report on the LXD side: https://github.com/lxc/lxd/issues/7224 I've reproduced this issue with: - wget http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-disk-kvm.img - qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -hda focal-server-cloudimg-amd64-disk-kvm.img -m 1G On the graphical console, you'll see EDK2 load (TianoCore) followed by basic boot messages and then a message from grub (error: can't find command `hwmatch`). Those also appear on successful boots of other images so I don't think there's anything concerning that. However it'll hang indefinitely and eat up all your CPU. Switching to the text console view (serial0), you'll see the same issue as that LXD report: BdsDxe: failed to load Boot0001 "UEFI QEMU DVD-ROM QM00003 " from PciRoot(0x0)/Pci(0x1,0x1)/Ata(Secondary,Master,0x0): Not Found BdsDxe: loading Boot0002 "UEFI QEMU HARDDISK QM00001 " from PciRoot(0x0)/Pci(0x1,0x1)/Ata(Primary,Master,0x0) BdsDxe: starting Boot0002 "UEFI QEMU HARDDISK QM00001 " from PciRoot(0x0)/Pci(0x1,0x1)/Ata(Primary,Master,0x0) error: can't find command `hwmatch'. e!!!!

If booting in a SecureBoot enabled environment, you instead get a `Access Denied` at kernel loading time, indicating that the kernel binary isn't a normal signed kernel. That has the same result (boot hangs) but without the crash message.
