EDIT by @AkihiroSuda

Update (Mar 14, 2022)

⚠️ Running recent Linux guests on M1 macOS needs Homebrew's QEMU 6.2.0_1 or later.

Run brew upgrade to upgrade QEMU.

Intel macOS users are NOT affected by this issue.

For the further information, see #734 and Homebrew/homebrew-core#96743 .

Old information

Ubuntu kernel 5.13.0-35.40 (5.4.0-103.117 for 20.04 LTS) released in March 2022 is not bootable on ARM hosts:

(hangs here)

Until the issue gets resolved, it is HIGHLY RECOMMENDED to run the following command inside the Ubuntu shell to avoid upgrading the kernel:

sudo apt-mark hold linux-image-$(uname -r)

(Make sure to unhold it when we get the fix)

If your kernel was already upgraded and the VM does not boot, try running Lima with the following environment variable to show the video display:

export QEMU_SYSTEM_AARCH64="qemu-system-aarch64 -display cocoa"

After the display is shown, press the Esc key several times to show the GRUB prompt for choosing an older kernel.
You can also mount the disk image from another instance to modify the GRUB config or rescue the data inside the image.

Description

Today I was working in lima VM (Ubuntu 20.04; Mac M1). After a while, it has lost connection (as it often does), so I had tried to restart it. Old VM and even brand new will not start and return an error after:

Waiting for the essential requirement 1 of 5: "ssh"

limactl --debug start VM-name prints:

I have the same error as mateka but limactl prune doesn't seem to delete the stored image. I changed the image url and when I execute limactl start docker it does not download the image but end with the same error.

limactl version 0.8.3
QEMU emulator version 6.2.0

My ~/Library/Caches has no lima folder. Any ideas? My serial.log looks pretty much the same as matekas.

Thanks in advance

I'm facing exactly the same issue, and fixed by using impish/20220201 image (as @mateka mentioned above).
It might be better to specify some stable release for images.location instead of the settings that changes its actual content unexpectedly such as impish/current.

Additional Experiments:

images.location status
impish/current(20220309)
impish/20220204
impish/20220201
focal/current(20220308)
focal/20220307
focal/20220302

Note: focal = Ubuntu 20.04 LTS

The diff 20220307...20220308 on focal might help us, but I don't know where it is.
Instead, there are package manifest files (.manitest). Run:

curl -o focal-server-cloudimg-arm64.manifest.20220307 https://cloud-images.ubuntu.com/focal/20220307/focal-server-cloudimg-arm64.manifest && \
  curl -o focal-server-cloudimg-arm64.manifest.20220308 https://cloud-images.ubuntu.com/focal/20220308/focal-server-cloudimg-arm64.manifest && \
  diff -u focal-server-cloudimg-arm64.manifest.20220307 focal-server-cloudimg-arm64.manifest.20220308 > manifest.diff

Then we obtain:

@huysal Maybe we should remove (limactl rm ...) the VM and create a new one. I did that and it worked for me.

@mateka @huysal @fuzmish Thank you for testing and analysis. Obviously, this is a regression on Ubuntu side.
I'll update the YAML to use the Feb revision of image, but probably apt-get upgrade is still affected 😞

No, please use limactl shell.

I'm facing exactly the same issue, there are some important projects files in this VM, and no backup anywhere else, so I could not rm this VM. And with output qemu display to cocoa and try to enter GRUB way, I am also failed. Keeping press ESC will lead me into UEFI menu. After I press continue inside UEFI menu, and then keeping press ESC, I could not enter GRUB menu ... Just get 4 EFI related information, including "EFI stub: ERROR: FIRMWARE BUG: kernel image not alligned on 64k boundary", and stuck there ...

Did I do anything wrong in enterring GRUB menu? Thanks for any help.


Update, thanks to response from @mateka, I have tried many times more, but still could not enter GRUB menu, and here is my workaround to save today's work:

Idea

  1. Create another VM by lima, let's named it ub21temp.
  2. Mount broken VM qcow2 image inside ub21temp
  3. Modify and save grub.cfg there

Implementation

  1. Create another VM by lima, let's named it ub21temp.
  2. Due to the dangerous to mount host home directory with "setting writable to true", we copy original broken VM (~/.lima/default) to an external hard drive(/Volume/${EXTHARDDRIVE}/default)
  3. Modify ub21temp lima.yaml, insert a new mount, which point to external hard drive(/Volume/${EXTHARDDRIVE}/default)
  4. Mount broken VM qcow2 image with ub21temp(modprobe nbd; qemu-nbd --connect=/dev/nbd0 /Volume/${EXTHARDDRIVE}/default/diffdisk; mount /dev/nbd0 ${AMOUNTPOINT})
  5. Modify and save grub.cfg there(/boot/grub/grub.cfg)
  6. Verify the VM in external hard drive is workable, and copy this one(/Volume/${EXTHARDDRIVE}/default/diffdisk) back to home directory(~/.lima/default/diffdisk)

I have restarted VM multiple times before configuring GRUB. Once it was stuck and was not accepting Esc. Other times it has not needed Esc to go into the GRUB menu.
