Linode recently replaced the AjaxTerm based web console with a Shell-in-a-box version. Also you can always access the console using SSH to the host instead of the web version.

Any virtualized Linux instance boils down to a VM running on a single host server. This is true at Linode, Amazon, Rackspace Cloud Servers, etc.
Xen and KVM instantiate a virtualized kernel per VM. Virtuozzo is a container/enhanced jail and runs under the host's kernel.
This is total FUD. Please check your statements for accuracy.
