Nothing output when trying to run with self-built Linux kernel #140

Closed paulmenzel closed 4 months ago

paulmenzel commented 4 months ago

With Debian sid/unstable and virtme-ng 1.25-1 trying to run my self-built Linux kernel ( config-6.10.0-04829-ge2f710f97f35), nothing is shown:

$ vng --version

Using this command line, adding earlyprintk=serial to -append (and adding the quotes) I get:

Could somehow be checked if the Linux kernel fulfills the requirements to work?

Hello,

trying to run my self-built Linux kernel

I guess it means you didn't use vng --build or vng --kernel, right? Some kernel configs are needed for vng to run.

It says that the kernel has not been compiled with the filesystem that is being used (9P in your case, I guess you didn't install virtiofsd), you are at least missing CONFIG_9P_FS=y, but best to run vng --kernel (or --build, or check the options that are added and take the minimal set for your case)

Using this command line, adding earlyprintk=serial to -append (and adding the quotes)

You can also use vng -v (...) ;-)

Indeed, CONFIG_9P_FS is unset (/boot/config-6.10.0-04829-ge2f710f97f35:# CONFIG_NET_9P is not set), and virtiofsd is not installed.

As always, thank you for the quick reply. As a convenience feature, virtme-ng could check the appropriate config file, if all required options are set.
