Three new scripts for VM-level infrastructure management: - audit-vm-disks.sh: Audit disk cache config on all VMs across hosts - audit-guest-io.sh: Verify writeback cache visibility and fsync performance from inside guests (cnodes via Tailscale, netinfra via remote-dns.sh) - deploy-tuned-guests.sh: Deploy tuned profiles to VMs via qemu-guest-agent (template for when guest agents are deployed fleet-wide) These establish repeatable processes for VM disk/performance auditing instead of ad-hoc one-off probes.
