Re: [libvirt-users] CPU and Memory requirements for host OS ( CentOS 7.6) on Dell Poweredge R630 server

That depends on what you plan on doing with the host. IIRC live VM migrations use host CPU time, and depending on transport can use quite a bit of CPU (for encryption/compression). Same with storage, if you have a ZFS/btrfs/LVM2/RAID/encryption setup that requires a lot of CPU, that's also counted against host CPU time. libvirtd itself doesn't need all that much resources for itself, that said. 2 cores and 2GB RAM should suffice as baseline? Plus whatever you need to meet above needs, if any apply.
