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.
