Works fine here. I gave this to qemu:
-cpu qemu64,+la57,vendor=GenuineIntel
it said:
qemu-system-x86_64: warning: host doesn't support requested feature:
CPUID.07H:ECX.la57 [bit 16]
because host is AMD, probably, and I have
CONFIG_X86_5LEVEL=y
enabled for the guest kernel and tip:x86/seves booted fine.
What am I missing?
