I am trying to build Fuchsia OS and run it on the Fuchsia Emulator femu, but after waiting for the emulator to start the fx command exists and displays the error below.
failed to create Fuchsia device device health check failed. Unable to ssh due to error:
Error: Cannot start Fuchsia Emulator. Exit status is 1
I have followed the instructions provided by Google at fuchsia.dev, the build completes successfully and the commands used to build the OS were
fx set core.qemu-x64 --with //examples/hello_world
fx build
Subsequently, I tried running in headless mode with fx vdl start -N --headless which results in the same error as above, I also tried build the OS without the --with argument but received the same error.
The log file gives us more details, the second last line of the log file may be of interest and it reads:
emu-system-x86_64-headless: network script /etc/qemu-ifdown failed with status 256
I am using Ubuntu 21.04 on my machine.
It seems that the network configuration scripts /etc/qemu-ifup and /etc/qemu-ifdown are missing. You can work around it by installing the qemu package:
$ sudo apt install qemu
