nkcr commented 4 years ago

Trying to use this example with kraft up -F -p kvm -m x86_64 helloworld-go from a virtual machine running ubuntu server 20.04.1 I get the following:

and /run/qemu-guest-13551_monitor.socket does not exist.

(if I use the --background option, the process is created but I don't know where to get the Unikernel's output)

This is a bug with socat. Downgrading to a slightly earlier version worked with me when I had this problem. 🙂

Great, thank you for the prompt answer :). I made a step forward using socat 1.7.3.4. Now this is what I get:

No worries. Looks like you have another different issue on your hands ;).

Closing as issue resolved.

The bug seems to be patched in socat 1.7.4.1.

" According to the Changelog from socat-1.7.3.4[1] this is a know problem (Under certain circumstances, termios options of the first address were applied to the second address, resulting in error "Inappropriate ioctl for device"). The upstream commit[2] fixes this issue (also released in socat-1.7.3.4).

Thanks, Sascha.
