[Discuss] KVM, virt-manager, and CentOS7

[markw at mohawksoft.com (markw at mohawksoft.com)]

I tried overt on a machine that was already hosting VMs. Needless to say,
I had to painstakingly restore my KVM environment to get them back.

The thing that I like about KVM and  libvirt is that it works within a
standard Linux system. I've tried vmware, parallels, and a number of other
vm environments, and they just didn't have the features to get the job
done. Networking between VMs didn't work or was a $$ feature. Snapshots
and disk compaction not available. Sharing CPUs during idle. The next step
up is vShpere and overt, which are so comprehensive that you are buried
with features and have to, more or less, commit to using their strategy.

Sure, if you want to run a large scale vm warehouse, something like overt
is for you. If you want to host a small-ish number of VMs, or use VMs to
develop/test software for different environments and operating systems,
KVM with libvirt is much easier to set-up and use.
