2 years ago Yes, we had a fix to this that wasn't pushed to main unfortunately, we don't use bzImage anymore because it's not supported by latest version of cloud hypervisor. Can u please pull, rebuild your image and try again

2 years ago Interesting results : This works on baremetal Ubuntu 20.04, but there is a lot of these error messages on ttys0 :
cloud-hypervisor: 812.392555ms:
WARN:vmm/src/vm.rs:436 -- Guest PIO read to unregistered address 0x87 cloud-hypervisor: 822.836755ms: WARN:vmm/src/vm.rs:461 -- Guest PIO write to unregistered address 0x4e
is this normal ?
Also I have strange mounts :
Filesystem Size Used Available Use% Mounted on dev 123.9M 0 123.9M 0% /dev run 129.6M 0 129.6M 0% /run tmpfs 129.6M 0 129.6M 0% /dev/shm /dev/root 725.4G 94.1G 594.4G 14% /new_root /dev/vda 20.0G 3.6M 19.5G 0% /new_root/opt/data
and this error message :
process virtiofs mounts ERROR: Root device mounted successfully, but /sbin/zinit does not exist. Bailing out, you are on your own. Good luck.
I suppose the /sbin/zinit is supposed to chroot in the /new_root ?
On a virtualbox VM, it kernel panic on boot (although I can boot the VM as I told on my first post) :
warning: use of deprecated parameter '--socket': Please use the '--socket-path' option instead. cloud-hypervisor: 2.153330199s:

Hi there,
I'm actually testing grid 3.0 and I am trying to create my own images for learning purposes, but also to be able to create an up to date k3s image whenever I want, so I was directed here by Ahmed (and also here)
On my ubuntu 20.04 host I was able to launch a VM with alpine rootfs, 5.14 kernel from here and virtiofsd-rs with cloud-hypervisor, following steps described here
But when I try your process, despite the kernel and initramfs creation seems OK, I've got this error message when booting the VM :
Could you please help me ?
