We clone a running VM in 2 seconds (2022)

>Virtual machines are often seen as slow, expensive, bloated and outdated.

by whom?

I tend to loathe firecracker posts because theyre all just thinly veiled ads for Amazon services.

Firecracker is not included in the standard linux KVM/QEMU duo and has sparse documentation. you cannot deploy a firecracker image like a traditional VM. in fact there are no tools to assist in creating a firecracker VM, and the filesystem for the VM must be EXT4.

TL;DR: this is all fun stuff if youre 200% cloud, but most companies run a ton of on-prem vms as well.

I was using ignite for a while to create firecracker vms, i think it’s called flintlock now. Ignite worked great when I was using it.
