While reading oVirt Wiki and other related docs, I came across multiple terms that meant the same thing (at least to me). Please take a look and let me know where I am wrong. 1) Difference between RHEV and oVirt node - oVirt node has VDSM and libvirt whereas RHEV only has libvirt. 2) 'RHEV-M server' is same as 'oVirt Engine Mgmt Server' is same as 'oVirt Engine'. 3) 'oVirt API' is same as 'REST API' is same as 'RHEV-M API' which is same as 'oVirt Engine API'. 4) 'Host Agent' is same as VDSM 5) 'oVirt Node API' is same as VDSM API. Question ) Guest Agent is running on VM. How does it get installed there? Regards, Sharad Mishra
