QEMU 'q35' machine type as the default for x86 arch
QEMU supports two main variants of "machine type" (think of it as a
virtual chipset) for x86 hosts: (a) 'pc', which corresponds to Intel's
'i440FX' chipset; and (b) 'q35', which corresponds to Intel's 82Q35
chipset. (For AArch64 hosts, the machine type is called: 'virt'). The
'q35' machine type provides some advanced features by default: native
PCIe hotplug (which is faster than ACPI-based hotplug, which older 'pc'
machine type uses), Intel IOMMU, faster SATA emulation, Secure Boot, and
so forth. This blueprint aims to make sure Nova handles it gracefully
when QEMU switches its default machine type to 'q35'.
