  template://docker

VM は aarch64

$ lima uname -m
aarch64

amd64 の container image を試す

$ docker run -it --rm --platform=linux/amd64 debian uname -m
x86_64

arm64 の container image を試す

$ docker run -it --rm --platform=linux/arm64 debian uname -m
aarch64
limactl create --name=default \
   --cpus=2 --memory=2 \
  template://docker

aarch64 + vz + rosetta

limactl create --name=default \
  --cpus=2 --memory=2 \
  --vm-type=vz --mount-type=virtiofs --rosetta \
  template://docker

aarch64 (arm64)

limactl create --name=arm64 \
  --arch=aarch64 \
  --cpus=2 --memory=2 \
  --vm-type=vz --mount-type=virtiofs \
  template://docker

x86_64 (amd64)

limactl create --name=amd64 \
  --arch=x86_64 \
  --cpus=2 --memory=2 \
  --vm-type=qemu --mount-type=9p \
  template://docker

Apple silicon で arch=x86_64 を指定する場合には vm-type=vz が使えない

field `arch` must be "aarch64" for VZ

また、mount-type=virtiofs も使えず、reverse-sshfs か 9p を指定する必要がある

field `mountType` must be "reverse-sshfs" or "9p" for QEMU driver on non-Linux
