Whiteboard

[1] may need updates to the host network card driver to allow TUN/TAP.

[2] A device tree based goal so you can have one kernel for both. Guest and host must be LPAE based. Marked DONE 2012-11-20 as you can boot the same kernel on guest and host now -- PMM.

[3] Might be a virtio shutdown device. Check if any other architectures do this without ACPI, or if the fast models do.

re: [3], SPARC uses a SLAVIO write, ACPI uses pm1_cnt write, CUDA uses CUDAPOWERDOWN, Nokia CBUS uses the watchdog, Highbank uses a device write, Bochs uses an I/O port, MIPS pseudoboard uses I/O, MilkyMist uses ICAP write, vexpress does write to cfgctrl, lm32 does write to R_CTRL, PowerPC uses sPAPR, S/390 uses intercept CPU_STOP, Alpha uses MPTR.

vexpress is fine for halt and restart. Does the kernel use it? v2m_power_off(), yes.
