What is the difference between VM and KVM?
VMware is an actual Type 1 hypervisor that runs on the bare-metal server hardware, increasing the performance of the tool over Type 2 hypervisors. KVM is technically a Type 2 hypervisor, as it runs on the Linux kernel, but it acts as though it is running on the bare-metal server like a Type 1 hypervisor.
How do I export a KVM virtual machine?
Exporting and Importing KVM virtual machines is a two-step process.
- First, you have to check where the disk images are stored and copy the disk image to a backup location.
- Secondly, export the machine configurations, so they can be later used to create the domain.
How do I restore a KVM virtual machine?
How to Restore a Live Backup on a KVM Virtual Machine
