It depends on Docker image – if it lacks systemd and /sbin/init, then you cannot run it in container machine. Here is my Rocky Linux 10 Dockerfile compatible with container machine:

FROM rockylinux/rockylinux:10

ENV container container

RUN dnf update -y && dnf install -y systemd
RUN (cd /lib/systemd/system/sysinit.target.wants/; for i in *; do [ $i == \
systemd-tmpfiles-setup.service ] || rm -f $i; done); \
rm -f /lib/systemd/system/multi-user.target.wants/*;\
rm -f /etc/systemd/system/*.wants/*;\
rm -f /lib/systemd/system/local-fs.target.wants/*; \
rm -f /lib/systemd/system/sockets.target.wants/*udev*; \
rm -f /lib/systemd/system/sockets.target.wants/*initctl*; \
rm -f /lib/systemd/system/basic.target.wants/*;\
rm -f /lib/systemd/system/anaconda.target.wants/*;

VOLUME [ "/sys/fs/cgroup" ]
CMD ["/usr/sbin/init"]

Save it as Dockerfile and run:

container build -t local/rockylinux:10
container machine create local/rockylinux:10 --name rockylinux
container machine run -n rockylinux

It mainly comes from official Rocky repo on Docker Hub, I've added systemd, because it was missing.

I created a repository for such Dockerfiles, already including Ubuntu 26.04 too 😄
