Hello!
I'd like to help you with this task. We need VMWare vCenter Server for cloning. What is your requirements for these VMs? Can you explain me your goals?
Probably it will be interesting for you: There is very useful feature in MS Hyper-V - deduplication. On my main job we have 82 Win8 VMs on 1 server, each VM has full disk (50GB, not thin disk), so all these 82 VMs have veight 2,48 TB, but with deduplication it's only 213 GB, because all VMs are similar. I can send you screenshot, if you will answer me.
About my experience: I have big experience with network administration (iptables, iproute2, ..). Big experience with OpenVPN servers/clients. Serial connection 2,3 servers for more security. OpenVPN over IPv6 and other.... Experience with VMWare ESXi (vCenter), MS Hyper-V, Proxmox VE, pfSense, Mikrotik and some different skills.
My another skills and reviews you can see in my profile.
Hope for cooperation!
Thank you!
