The OpenBsd installation cannot enter the system after the USB flash drive is started.

I successfully installed openbsd on a USB drive without problems.
but you can"t load the kernel after startup, let alone enter the system. I tried to install successfully in the virtual machine and enter the system.
doesn"t it support flash drive startup?
