I am developing an application that would essentially control/run VMs on a X86_64 host machine. The existing OS is 32 bit based so the application needs to be 32bit too. KVM/QEMU are 64 bit so that guests could be either be 32 or 64 bit. Does using libvirt as 32bit library on a 64bit host (capable of hosting 32 and 64 bit guests) pose any problems? Will it even work?
