Super-multi-hypervisor on one disk?

Question

System administration

Good day! I want to install Hyper-V, VMware, Citrix XEN and proxmox on one disk. I know what happens with two Hyper-V and then Proxmox, because the last ala Linux and grup itself recognizes Windows. But what to do with the rest, eats their grup?

Answer 1

windows and xen are easy, with vmware xs in theory there will be no problems, try to put each of them in turn, transferring a copy of the bootloader settings to a separate flash drive in grub, put vmware last (I don’t remember if it will allow not to install on the entire disk), later start loading from a flash drive if you need windows or xen, and if vmware then from a disk
. For Linux, it makes no difference whether the bootloader is located in the same place as the system files themselves, for windows, in principle, too, but a little more manual work will be needed
. vmware has its own proprietary bootloader
