Provide "nosnp" boot option via "sev=nosnp" kernel command line to prevent SNP-capable host kernel from enabling SEV-SNP and initializing RMP table. On providing sev=nosnp via kernel command line: cat /sys/module/kvm_amd/parameters/sev_snp should be "N". This patchset is based on tip/master. Any feedback is much appreciated.
