Build SNP kernel

[pegahnikbakht]

Hi,

I'm following this guide https://github.com/kata-containers/kata-containers/blob/e5e0983b56534f007cf06ab39f323961b17ff642/docs/how-to/how-to-run-kata-containers-with-SNP-VMs.md to setup an SNP container, I'm running this on a bare metal machine with SNP support and the kernel is 6.9.0-rc1-snp-host-f9b5bc22b945
When I try the following command ./kernel/build-kernel.sh -a x86_64 -x snp setup snp is not accepted as an option in this command, how should I pass snp to the script?

Thanks in advance.

That guide is a bit out of date. These days you should be able to run SNP guests with the confidential kernel that we build for coco or really with a wide variety of upstream kernels.

I tried coco first and I had too much problem with it, also in their release note of v.0.8 they say SNP is untested or partially supported! I'm looking for something more stable.

You should be able to start a pod with SNP on v0.9.0 or v0.9.0-alpha0. Make sure that your host kernel and guest kernel are in sync.
