Re: [kvmarm-user] The role of Qemu in booting guests

[mabel mary joy <mabeljoy@xxxxxxxx>]

Thank you so much for the quick answers.

Yet another question I have is whether the KVM for ARM have real time support capabilities. i.e. Is it possible to run a real time guest OS at the moment on KVM for ARM?

Also why do we supply root file system through nfs for host and not as an image as we do for the guests?
Why did we use cramfs file system?

 

The NFS selection for the Host is purely for convenience. Assuming that you are on FastModels, your other options are either an initrd (supplied via the semihosting features or embedded in the bootwrapper itself) or an MMC image. The same applies for the guest, with the difference being that MMC and NFS booting are far too slow compared to initrd due to the emulation overhead.

 

Is the kernel bound to a particular root file system ? i.e could a kernel use another root file system ?

I am not sure I completely understand your question, but yes, you can use a root file system of your choice.
