devstack/tools/xen/scripts/manage-vdi
John Garbutt 030fb2362f Make devstack work with xcp-xapi package on Ubuntu 12.04
- allow you to configure the xenapi_user (often other than root)
- allow you to disable the guest installer network
- install the plugins in the xcp-xapi location
- use alternate webserver location when adding the preseed file
- skip the centos specific ip forwarding configuration
- make use xcp inventory, if no xensource-inventory is found
- correctly deal with kpartx to mount the VM VDI in manage_vdi
