Yes, this is Microsoft's "agent-based migration" option mentioned in the article.

Agent based requires an insane amount of privileged accounts and I would say fails for 10%+ of the VM population

Probably better to get the vm into a ramfs or any other way to not be currently on it. Otherwise it'll likely be pretty corrupted

Try doing that to 3,000 production VMs.

Where do you work that a single sysadmin manages 3000 VMs?

We're running a migration from VMware to Red Hat Openshift Virt for one customer right now which is over 150,000 VMs. That's a big one, but five figure number of VMs is very typical.

I gave a 5 min lightning talk about this a couple of years back: https://pretalx.com/devconf-cz-2024/talk/SN93LG/

People talking here about Proxmox make me laugh.

We have a (what I thought was) large nutanix setup at $dayjob for epic emr... we have like 10-12 sysadmins for ~500 servers (end user apps, and backend infra like Citrix), and even that seems like a lot.
