Kernel-based Virtual Machine (KVM) vs. VMware vSOM (discontinued)

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.

Vsphere Operation Management is suitable for automating the process of bringing up an alternate data center in case of a disaster. It also is a great way for testing your readiness of disaster. You have the ability to bring up a server in a "bubble" for testing. This way you can show your admins how the failover process will work.

• KVM is really good at providing fast and reliable virtualization for Linux guests
• Since KVM is a kernel module, every VM is a Linux process which can be managed by Linux system tools
• KVM integrates very well with the management framework libvirt, which is why KVM can be integrated in automation tools as well

• The best thing about VSOM is that it's built into VCenter so you only have one point of administration
• VSOM does a great job of making applications intuitive
• Re-IPing virtual machines are a must and VSOM does a great job of making this a simple process

• KVM itself doesn't ship with a management interface
• KVM itself is a bit complicated to handle
• KVM needs Qemu to virtualize Windows guests

• The installation of VSOM is very tedious
• It uses an MS SQL database
• It should be able to adjust for hardware modifications in VCenter

It does the job and stays out of the way. The specifics of usability relies on the implementation, but with things like Icarus and libvirt, things are standardizing nicely.

It is a very reliable solution that can be used for x86 architecture virtualization with low overhead. It is a free and open source software. Easy to use withOpenStack.

vSphere with Operations Management has a much better way of automating the re-IPing of servers so you can stand them up in a different environment or location. You do, however, need another way of replicating your servers to your DR site, VSOM will not do that. We used EMC Recover Point for replication.

• Fast provisioning of new servers.
• Huge drop of the cost of servers compared to bare metal.
• Easy upgrades of resources, sometimes now even requiring a server restart.

• In the case of a disaster, the ROI would be substantial.
• The license for VSOM is pretty expensive initially.
• Support for VSOM is terrific.
