We still need to figure out how we're going to get the CIM v2.16 Exp schema on the box, but if you do that manually (into /root/virt) before installing the RPM, it works as expected.

[PATCH 0 of 5] VSMS Dynamic Devices
by Dan Smith 08 Nov '07

08 Nov '07

This set adds dynamic attach/detach support to device_parsing, as well as some other tweaks necessary for the changes to VSMS to work. This makes VSMS dynamically attach/detach devices if the domain is running. Currently this only works for Network and Disk devices, but adding processor and memory support in the attach functions should be easy.
