Is it possible to combine the resources of several physical machines to run one virtual machine on them?

Question

System administration

The situation is as follows:
There are 2 physical machines, each with 1 GB of memory and one 4-core processor.
So, is there any means to create one virtual machine with 8 virtual
cores and 2GB of memory, but with all this, the load is distributed to these two machines and
one physical core per virtual and memory is involved also distributed
between these physical machines? Is it possible?

Answer 1

This is called horizontal clustering. And physically, this will not work out due to the huge lag between the network speed and the memory access speed. But some software can be configured in this way according to the principle of master-slave operation, some cannot.
