WebMar 22, 2024 · QEMU has generally good support for ARM guests. It has support for nearly fifty different machines. The reason we support so many is that ARM hardware is much more widely varying than x86 hardware. Webvirt. ) The virt board is a platform which does not correspond to any real hardware; it is designed for use in virtual machines. It is the recommended board type if you simply want to run a guest such as Linux and do not care about reproducing the idiosyncrasies and limitations of a particular bit of real-world hardware.

Migration. QEMU has code to load/save the state of the guest that it is running. These are two complementary operations. Saving the state just does that, saves the state for each device that the guest is running. Restoring a guest is just the opposite operation: we need to load the state of each device.
