My bad, I accidently removed the bootindex setting, which is required to actualy boot from the usb disk. It is present in the link of my signature, but not in the "updated" command sequence I posted earlier.   # set vm id id=930 # create image directory, download and uncomporess mkdir -p /var/lib/vz/images/${id} curl --location https://github.com/pocopico/tinycore-redpill/raw/main/tinycore-redpill.v0.4.4.img.gz --output /var/lib/vz/images/${id}/tinycore-redpill.img.gz gzip --decompress
