KVM - CAP_ARM_USER_IRQ
Issue
When trying to run a KVM VM :
qemu-system-aarch64: Initialization of device arm_gic failed: KVM with user space irqchip only works when the host kernel supports KVM_CAP_ARM_USER_IRQ
Potential fix
Back porting these patches 70 to 74 and QEMU needs to be patched accordingly as well.
