macOS 14.3 on vmapple doesn't boot

[frefire]

The KernelCollection compiled successfully. And I disabled SIP and used 'kmutil configure-boot' to setup the new collection. The machine is in UTM with Apple's virtualization.framework. But no matter what I do, when I reboot, it always show a window that says "Custom kernel failed to boot" with no panic log at all. I don't know what I've missed. I've tried every way to use 'kmutil configure-boot' that I could google but nothing works. The result is always the same.

Can you help? Thanks.

Did you create the kernel collection via kmutil in a Virtual.fw VM?

Yes, I create the collection on the same machine that I boot-configure on, which is the virtualization.framework based UTM, and I also double checked MACHINE_CONFIG=VMAPPLE

Virtualization.framework guests on 14.3 and older will not boot custom kernels without some modifications.

Guests running 14.4 and on should allow you to boot custom kernels without these changes.
