Hello List, I have a proposal and wont mind to implement my self but need a helping hand to start on. I want to implement the aggressive FT feature in XCP. The best way I could imagine is the use of feature *Live Migration* Steps 1. Enable the FT of a particular VM using xe commands and adding as a param to that VM e.g. xe vm-param-set FT=true uuid=XYZ 2. If the FT = true detected by xenstore then xapi will initiate a live migrate of that VM to any of available host. 3. A parallel "network ping"/"xapi heartbit" from/to that host could be initialized for each FT VM. 4. Live migrate will run forever until its disabled by FT = false or one of the host is down. e.g. the process will loop at 99.99% migration state 5. If there is a packet drop of x packets the VM Migrate procedure will mark the VM Migration as Complete and will switch the devices forcefully. -- this could result in some data loss but I dont have any alternative to this. -- The specific x packets can be set by XCP but we cant rely for default XCP Errors 6. If there is a successful migration due to host down then we will again start from step2 Above steps I have assumed to my knowledge, we can discuss the problems in it. Apologies if I'm being too naive.
