The image flatcar_production_iso_image.iso is panicking on QEMU.

Can't start the iso on QEMU, making it unusable with Packer, for example.

Flatcar should boot.
I tried using the vmlinuz and cpio.gz from the iso so I could get the kernel panic trace, but it also fails with the iso image as a CDROM.
The text was updated successfully, but these errors were encountered:
Oops, just found the problem. 512M doesn't seem enough for this image. Increased it to 1024M and it booted :)
Sorry, something went wrong.
