guys, I am trying to launch Linux emulation on Risc-V platform using Qemu. I did it step by step using this tutorial https://risc-v-getting-started-guide.readthedocs.io/en/latest/linux-qemu.html
On the last step, when I starting this thing it gives some errors (they are mostly at the bottom of console output):

I tried reinstall it several times, but it has not any result.
Be nice, please, I’m quite new to system emulators.
No filesystem could mount rootWhat root filesystem did you give to qemu?
