We running separate database of virtual machines for our purposes and around 1000-1500 VM's syncing starts to be too long and slow.
I thought we can use some non-RPC based mechanism to access database (even if this will cost us compability with other versions of xapi). /json actually is RPC too, so it take too much time to use in very 'lively' environment. We need last_boot to know about shutdown reason - it pretty important information. В Пт., 18/02/2011 в 10:17 +0000, Jonathan Ludlam пишет: > Hi George, > > What do you mean by 'fast sync'?
