Resuming from hibernation on another hardware?

Question

linux

Is it possible to implement the following case. The OS is on a flash drive. I run some software, let's say I put something to compile, then I hibernate (suspend to disk). I pull the flash drive, go to work, stick the flash drive into another computer and continue to work from the same place.

Answer 1

This is only possible when using virtualization systems such as virtualbox/kvm/qemu/vmware (openvz/lxc/.. by the way supports migration, but there will be more hardware requirements), at the cost of about 10%+- CPU performance loss (in some cases, working with disk on a virtual machine will be noticeably faster), i.e. when a virtual machine will be responsible for the simulated layer with equipment. When using hardware virtualization, changing the architecture of the processor can interfere, on the other hand, when using full processor emulation, the performance loss will be 10-fold.
Read the documentation for virtualization systems on live migration.
In theory, if both machines have an identical config, then with a lot of luck everything should work, we are talking about the motherboard, processor and peripherals such as a video card. Any removable peripherals such as mice, sata disks and other things, in theory, will not interfere (it is possible to place a swap file and hibernate on a disk that has changed will be fatal for the OS).
