The instructions on the README are wrong

[rminnich]

alioth -l info --log-to-file       run       --kernel ~/tmp/vmlinuz        --cmd-line "console=ttyS0"       --initramfs ~/tmp/initramfs.linux_amd64.cpio       --mem-size 4G       --num-cpu 2

returns

Please update the cmd line to --memory size=4G,backend=memfd

Then it hangs.

Thanks for the feedback! I think there are 2 issues here,

1. The instructions are not updated after --mem-size is deprecated and --memory is introduced. I will update the doc later.
2. There are some known issues with VCPU synchronization in the error handling paths. In your case, most likely that the BSP thread had some errors and the AP thread were waiting BSP thread indefinitely. One quick workaround is to change --num-cpu to 1 and see what is the error in BSP thread.

It should be fixed in #205
