When a computer runs out of ram it relies on placing pages on disk. But if an host OS runs a VM and the host runs out of space, can VM pages be placed on disk or are they required to stay in RAM for the VM to function ?

Also are pages placed on disk only when the computer runs out of RAM, or does the OS sometimes allocated "fake" memory even if some physical memory is still free ?

The VM is just a program. There may be some conflict with the VM paging alg and the host alg but this is a problem virtualization solutions work to solve via drivers and instruction sets.

As for swapping, that depends on the OS. Memory is used for more than just program memory, so different approaches to swapping will have different benefits. For Linux at least, there is a kernel parameter called swapiness that you can use to change the kernel's predilection for swapping to disk.

In the most simple case the guest OS would just swap to the virtual disk image attached to the VM
