Multiple users accessing KVM

How can I have multiple users access our kernel-based virtual machine at the same time? Can we use some sort of screen sharing to get around the 1 user at a time limit?

Cost of virtualization and diminishing rate of returns

JennyMack — Wed, 29 Apr 2009 20:31:02 +0000

The following question was recently submitted via e-mail by a user:

Using ESXi 3.5. I’ve seen tests done that usually put the cost of virtualization at 25% when VMs don’t share the same kernel, and 10% when they do. I’ve noticed as you drop cores, the cost of virtualization as a percent of the total goes UP disproportionately. Is anyone else finding this? Is there a “sweet spot” for virtualization configuration in terms of price?
