Macで`$colima start`を実行しようと思ったらエラーが出た際の解決メモ

Macで$colima startを実行しようと思ったらエラー

$ colima start
FATA[0000] limactl is running under rosetta, please reinstall lima with native arch FATA[0002] lima compatibility error: error checking Lima version: exit status 1

以下のようにしたら少し解決した

1) Make sure you’re not in a Rosetta shell

Quit Terminal/iTerm → Finder → Applications → (Terminal or iTerm) → Get Info → uncheck “Open using Rosetta”.

Reopen a fresh shell and run:

arch            # should print: arm64
uname -m        # should print: arm64

2) Ensure you’re using the arm64 Homebrew
which brew
brew config | grep HOMEBREW_PREFIX     # should be /opt/homebrew


If it’s /usr/local (Intel brew), fix your PATH and restart the shell:

echo 'export PATH="/opt/homebrew/bin:/opt/homebrew/sbin:$PATH"' >> ~/.zshrc
exec zsh -l

3) Remove Intel lima and install native arm64
# See if multiple limactl are on PATH
command -v -a limactl

# Force arm64 brew for safety
arch -arm64 /opt/homebrew/bin/brew uninstall --force lima colima || true
arch -arm64 /opt/homebrew/bin/brew install lima colima

4) Verify it’s arm64 now
file "$(which limactl)"   # should say: Mach-O 64-bit executable arm64
limactl --version

5) If it still complains

You may have stale Intel VMs or a shadowed binary.

# Check for shadowing
which -a limactl          # remove any from /usr/local/, MacPorts, Nix, asdf, etc.

# (Optional) reset Lima VMs – this deletes them; back up first if needed
limactl stop --all || true
mv ~/.lima ~/.lima.bak.$(date +%Y%m%d-%H%M)


Paste the outputs of:

arch
brew config | grep HOMEBREW_PREFIX
command -v -a limactl
file "$(which limactl)"

その後、また$colima startを実行しようと思ったらタイムアウトエラー

以下によりまた少し進む

1) Sanity check (one-time)
file "$(which colima)"     # should be arm64
file "$(which limactl)"    # should be arm64
colima version
limactl --version

2) If it finishes
colima status
docker info
docker run --rm hello-world

3) If it stalls on “downloading disk image…”

Try these in order:

Verbose logs

colima start --verbose
# or watch the Lima logs:
tail -f ~/.lima/colima/serial.log


Network/proxy hiccup reset

colima stop || true
colima delete -f
# Best settings for Apple silicon, no guest Rosetta:
colima start --vm-type=vz --arch=aarch64 --cpu=4 --memory=8 --vz-rosetta=false


(--vm-type=vz uses Apple’s Virtualization Framework; faster and cleaner on M-series.)

Behind a proxy? Start with your proxy env vars set:

export HTTP_PROXY=http://proxy:port HTTPS_PROXY=http://proxy:port NO_PROXY=localhost,127.0.0.1
colima start --vm-type=vz --arch=aarch64 --vz-rosetta=false


Check which image URL is failing
Open the log and look for the download URL:

grep -i 'download' ~/.lima/colima/serial.log | tail


If you see repeated timeouts, it’s a network issue (VPN, proxy, firewall).

4) Common “gotchas”

Make sure Terminal/iTerm isn’t launched “Using Rosetta”.

Ensure you’re on /opt/homebrew (arm64) brew in your PATH.

Don’t mix Intel/arm64 installs of Colima/Lima.

If it still sticks, paste the last ~30 lines of ~/.lima/colima/serial.log and the output of:

colima status
limactl list --detail


and I’ll zero in on the exact cause.

実行

% colima start
FATA[0059] error starting vm: error at 'creating and starting': error getting qcow image: error during image download: error downloading 'https://github.com/abiosoft/colima-core/releases/download/v0.9.0-2/ubuntu-24.04-minimal-cloudimg-amd64-docker.qcow2': exit status 56

QEMUをインストールしてリトライ

If you do want to use QEMU

Install it via Homebrew:

brew install qemu


Then retry:

colima start --vm-type=qemu --arch=aarch64

動いたような気がするので様子をみてみる

% colima start --vm-type=qemu --arch=aarch64 INFO
