I don't think your other VMs would be in any danger. This is a classic example where you can say virtualisation can be used safely and where the technology is better than mere "containers" which would arguably put you in a bad spot. Imagine that is if a silly OpenSSL exploit could access the physical host, what a full fledged program could do. This is not the case, clearly; it would mean Google Compute Engine (and all KVM providers) would suddenly be pwned. Lucian -- Sent from the Delta quadrant using Borg technology! Nux! www.nux.ro
