@sboeuf Thanks for taking time to take a look! - The disk `ubuntu` is downloaded from https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64.img, without any changes. - When i change flag `--console pty` to `--console off`,...

@sboeuf - Switch off `direct` flag, same result. - Host kernel version from file /proc/version: `Linux version 4.15.0-191-generic (buildd@lcy02-amd64-032) (gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04)) #202-Ubuntu SMP Thu Aug 4 01:49:29...

I changed host to Ubuntu 22.04 (kernel 5.15.0-47-generic) for cgroups v2. Actually, a guaranteed pod's memory cgroup will set `memory.high` to `max`, equal to the value of `memory.max`. And the...

The field `cache` only exists in the file `memory.stat` of cgroup v1, means the bytes of page cache memory. IIUC, the `cache` is similar to the field `file` in `memory.stat`...

Sorry for the late replay! There is a usual way to reproduce this issue without container. step1. Download firmware from https://github.com/cloud-hypervisor/rust-hypervisor-firmware/releases/download/0.4.1/hypervisor-fw step2. Download cloud image https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64.img step3. Use `guestfish` to...

@likebreath Thanks for trying to reproduce the issue! Did you put the PID of CH to cgroup during booting? Or on ubuntu 20.04 with cgroup v1, you can follow these...

I have updated some errors in instructions to reproduce the issue.

@likebreath I have tested on ubuntu 20.04, and CH was killed. Maybe you added the PID of CH to cgroup after guest OS booted? @sboeuf I have tested the patch,...
