It's either pointing to a bad binary or re-compile. May 8, 2024 67 8 8. I see that If you don’t care about live migration or have a homogeneous cluster where all nodes have the same CPU and same microcode version, set the CPU type to host, as in Virtual machines in Promox are based on QEMU/KVM, which allows for emulation of different CPU types using the CPU TYPEsetting. 3 will change the default CPU type to 'KVM64'. In short, if you care about live migration and moving VMs between nodes, leave the kvm64 default. 05. I am facing random freezes of the whole on Proxmox 8.
