Hi all,
Im trying to run openwrt via qemu on a Pi like this:
qemu-system-aarch64 -M virt -m 128m -kernel openwrt-21.02.1-armvirt-64-Image -drive file=openwrt-21.02.1-armvirt-64-rootfs-ext4.img,format=raw,if=virtio -no-reboot -nographic -nic user -nic user -cpu cortex-a53 -smp 2 -append "root=fe00"
It did the trick (just booting for now...) but I get 100% CPU on one core for ever... and I also dont know why if I try to switch to -cpu host I get "qemu-system-aarch64: unable to find CPU model 'host'"
I havent done anything else other than booting and waiting to stabilise.
Any qemu aficionado to help me a bit?
Thanks
