With xen_no_vector_callback on the command line, the hypervisor doesn't realise that the guest is 64-bit until long after all the CPUs are brought up. It does boot (and hey, QEMU does get this right!) but I'm still concerned that all those shared structures are 32-bit for that long. I do think the guest kernel should either set the hypercall page, or HVM_PARAM_CALLBACK_IRQ, as early as possible. $ ./qemu-system-x86_64 -display none -vga none -serial mon:stdio -accel kvm,xen-version=0x4000a,kernel-irqchip=split -smp 2 -kernel ~/git/linux-2.6/arch/x86/boot/bzImage -append 'root=/dev/xvda1 console=ttyS0 xen_no_vector_callback earlyprintk=serial' -drive file=/var/lib/libvirt/images/fedora28.qcow2,if=xen -trace kvm_xen\* -m 2g kvm_xen_soft_reset kvm_xen_set_vcpu_attr vcpu attr cpu 0 type 0 gpa 0xffffffffffffffff kvm_xen_set_vcpu_attr vcpu attr cpu 0 type 1 gpa 0xffffffffffffffff kvm_xen_set_vcpu_attr vcpu attr cpu 0 type 2 gpa 0xffffffffffffffff kvm_xen_set_vcpu_callback callback vcpu 0 vector 0 kvm_xen_set_vcpu_attr vcpu attr cpu 1 type 0 gpa 0xffffffffffffffff kvm_xen_set_vcpu_attr vcpu attr cpu 1 type 1 gpa 0xffffffffffffffff kvm_xen_set_vcpu_attr vcpu attr cpu 1 type 2 gpa 0xffffffffffffffff kvm_xen_set_vcpu_callback callback vcpu 1 vector 0 Probing EDD (edd=off to disable)... ok [ 0.000000] Linux version 6.13.0-rc2+ (dwoodhou@xxxxxxxxxxxxxxxx) (gcc (GCC) 14.2.1 20240912 (Red Hat 14.2.1-3), GNU ld version 2.43.1-2.fc41) #2210 SMP PREEMPT_DYNAMIC Mon Jan 6 17:10:02 GMT 2025 [ 0.000000] Command line: root=/dev/xvda1 console=ttyS0 xen_no_vector_callback earlyprintk=serial [ 0.000000] BIOS-provided physical RAM map: [ 0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000009fbff] usable [ 0.000000] BIOS-e820: [mem 0x000000000009fc00-0x000000000009ffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000000f0000-0x00000000000fffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000000100000-0x000000007ffdffff] usable [ 0.000000] BIOS-e820: [mem 0x000000007ffe0000-0x000000007fffffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000feff8000-0x00000000feffffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000fffc0000-0x00000000ffffffff] reserved [ 0.000000] printk: legacy bootconsole [earlyser0] enabled [ 0.000000] NX (Execute Disable) protection: active [ 0.000000] APIC: Static calls initialized [ 0.000000] SMBIOS 2.8 present.
