SLE15SP3 autoinstallation profile not suitable on SUMA4.2 from github

Hi,
I’m trying to provision new device by autoinstallation in AutoYaST XML profile with github SUSE/manager-build-profiles/AutoYaST on SUMA4.2,

I can boot baremetal on KVN/QEMU from bios in init ramdisk, but shown no filesystem could mount root and kernel panic in VM console, can you please kindly help to solve this issue.?
