Hello all, I get the message "qemu kvm_arm_vcpu_init failed: Invalid argument" which I refer to the source file code "https://git.qemu.org/?p=qemu.git;a=blob;f=cpus.c;hb=refs/ heads / stable-2.11 # l1122" and "https://github.com/qemu/qemu/blob/master/accel/kvm/kvm-all.c " Row 444. I don't know which vCPU feature is expected ... #cat /proc/cpuinfo processor : 0 BogoMIPS : 48.00 Features : fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid CPU implementer : 0x41 CPU architecture: 8 CPU variant : 0x0 CPU part : 0xd03 CPU revision : 4 .... is it currently or later even possible to use virtualization?
