This works on top of qemu or other manager or it’s 100% developed by ZimaOS?
What’s the performance difference compared to qemu + libvirt (Virtual Machine Manager from Store)
Its KVM+QEMU and no they didn’t develop those opensource projects.
There will be no perf difference, the virtual machine manager app is just a management UI on top of the underlying KVM+QEMU.
Libvirt is a single consistent library to manage virtual environments, it will have no direct effect on speed of whatever virtualization system it is managing.
KVM+QEMU+Libvirt are all installed, libvirtd seems to be running, i have been unable to connect to with VMM, but i am not a VMM expert so i probably did something wrong
