Failed to load `sev-guest` module #190

Hi, I am trying to load /dev/sev-guest, but it fails with could not insert module ./sev-guest.ko: No such device. Does anyone have similar problem?

My dmesg | grep -i sev of guest kernel is

[     0.166648] Memory Encryption Features active: AMD SEV SEV-ES

My kernel is 5.19.0-rc6-snp-guest-c4daeffce56e. I launched the kenel with SEV-ES only for some reason.

I found sev-guest.ko under /lib/modules/5.19.0-rc6-snp-guest-c4daeffce56e, but insmod ./sev-guest.ko does not work due to the above reason.

sev-guest is available only when SEV-SNP is enabled.
