This document is a work in progress to help me keep track of stuff while trying to get Rancher running on openSUSE MicroOS in a virtual machine on a Proxmox host.
# import a qcow2 as a disk to an existing vm
qm importdisk <vmid> openSUSE-MicroOS.x86_64-kvm-and-xen.qcow2 local-lvm
This is how I made the combustion/ignition virtual drive
# prep combustion
mkdir ./drive
mount /dev/pve/vm-104-disk-1 drive/
mkdir -p ./drive/combustion
umount drive[ OK ] Closed D-Bus System Message Bus Socket.

Entery emergency mode. Exit the shell to continue.
Type "journalctl" to view system logs.
You might want to save "/run/initramfs/rdsosreport.txt" to a USB strick or /boot
after mounting them and attach it to a bug report.

(or press Control-D to continue):
Then I did the following in the vm shell to get the rdsosreport.txt and other info dumped to the combustion drive
# remount the combustion drive as rw
mount -o remount,rw /run/combustion/mount
# copy rdsosreport
cp /run/initramfs/rdsosreport.txt /run/combustion/mount
# make a dump of mount
mount > /run/combustion/mount/mount.txt
# get journalctl
journalctl > /run/combustion/mount/journalctl.txt
# get dmesg
dmesg > /run/combustion/mount/dmesg.txt
# stop the vm
poweroffTo extract the info from the combustion drive onto the proxmox host
mkdir drive
mount /dev/pve/vm-104-disk-1 drive
cp drive/*.txt .
umount drive
