This virtual open systems guide is absolutely ancient: it must be at least a decade old, and dates from the very early days of KVM on Arm. I can't read the whole document, but I would not be surprised if they were using a custom branch of QEMU, or they might have been using a QEMU from before we added emulation of TrustZone to that board (which KVM can't emulate). You can see in the instructions that they're using a custom branch of the guest kernel (and a very ancient kernel). It's not a very good guide to what will work today. > On the devuan 4 host os that I have installed I'm using kernel 5.4,that's > lower than 5.7,so the qemu support for it should be there. It's in the kernel, but you're using a QEMU which has dropped the support. -- PMM
