Overall Satisfaction with Kernel-based Virtual Machine (KVM)

Linux KVM is a powerful and free (in the case of using Ubuntu for example) virtualization tool. In our organization KVM plays a significant role in DevNet related implementations (especially by using in pair of network appliances + KVM with a variety of firewall/router/VPN box images). AT&T which is one of our carriers and the most well-known SP is also using KVM in its FlexWare environment (Juniper NFX hardware + KVM + vEX/vSRX images).
  • Lightweight built-in implementation for all *nix based OS.
  • Easy to deploy and manage VMs.
  • Freeware (is you are using a free OS).
  • Monitoring features (unclear SNMP MIB DB, do not support by the monitoring systems, like Solarwinds and etc.)
The key points why I made my decision for KVM in comparison with VMWare are: Freeware software (I am using an Ubuntu server OS), Fewer resources usage, vSwitch using that provides the ability to configure dot1q trunks to/between VMs, Stability, and simplicity of using/troubleshooting, Well-known interface (for Linux geeks).

Yes

Would you buy Kernel-based Virtual Machine (KVM) again?

Yes

KVM is the best solution in the case you need to test and turn up any virtual environment with limited vCPU/RAM resources. The obvious area of its use is a network environment when we want to avoid being tied to one type of hardware/vendor and being able to swap from one instance to another with no downtimes. The use of a vSwitch (that supports VLAN tagging) is a significant bonus for network engineers that some other hypervisors do not provide.
