![]() In the physical host Proxmox you create 2 VM, and in each one install a new instance of PVE, so you can experiment with cluster concepts without the need of having multiple physical servers. Once installed the guest OS, if GNU/Linux you can enter and verify that the hardware virtualization support is enabled by egrep '(vmx|svm)' -color=always /proc/cpuinfoĮxample: PVE hosts a PVE guest hypervisor Set a cluster of self-nested PVE Proxmox as nested Virtualization Environment. Then create a guest where you install e.g. (pay attention where the dash "-" is used, and where it's underscore "_" instead) # echo "options kvm-amd nested=1" > /etc/modprobe.d/nfĬheck cat /sys/module/kvm_intel/parameters/nested (or "kvm-amd" for AMD, note the 1 instead of Y): # echo "options kvm-intel nested=Y" > /etc/modprobe.d/nf N means it's not enabled, to activate it ("kvm-intel" for intel): To check if is enabled do ("kvm_intel" for intel cpu, "kvm_amd" for cat /sys/module/kvm_intel/parameters/nested
