proxmoz system "forklift" help

Hi,

I am new to proxmox and have a slightly unusual task I want to use it for. In the long run this will be your typical proxmox setup with containers and VMs in a cluster.

I am an IT consultant that is working for a small engineering group and there are strong reasons to believe that some of their systems have been compromised. These are Centos systems. One machine in particular needs to be recovered in a safe way and it's functions extracted into multiple VMs.

I have added a small disk that is running proxmox and I am looking to use this to safely work on the suspect system in place. I can mount the system disk and look at the files and I can do simple things like chroot and reset passwords. The real thing I need to do is run these disks as a VM without networking and use the console to access and take the machines apart.

How can I use the existing disk as a VM in proxmox? How can I set the VM up with no networking?

thanks in advance,
jerry
