Host management (idea)

should manage the following data.

• Unique Nickname
• IP address or FQDN (multiple ?)
• Host attribute (VM, Hypervios, Simple physical host?).
• Parents if VM.
• Children if Hypervisor.
• sibling (It can substitute Parent's children except for me?)
• UserName/Password for SSH (and rlogin in the future?)
• KeyPair for SSH.
• Information for OpenStack operation (Tenant name, User/Password)
• OpenStack operations w/o explicit user/password in the shell.

Registeration ways

• Automatically (from ZABBIX, Nagios, and Openstack): same as the current
• Manually (How should I merge it with the automatically obtained one

ID

• Should we use string ID, because OpenStack's ID is UUID string?

API

• getHypervisor(VM Host ID)
• getChildren(HostID)
• doCommand (Host ID)
