So, I'm trying to figure something out about SQL Server running on a VM. So the use a VMotion makes sense to me for a planned move of a VM ... memory structures are copied, and once both VM's are identical the switch is made.
But is there also a hot backup concept when talking about VM's (and maybe it's categorized under VMotion) too? It seems like I've heard people talk about VM's as a solution for failover. So if a VM "MY_VM" is running on SERVER1, and SERVER1 fails, then MY_VM can be brought online on SERVER2. But this sounds like it opens ups the chance for corruption in the case of SQL Server, since it would seem that the memory structures would be inaccessible.
So, is this "hot backup" even a possibility within the VM environment, and if so, is there more protection being performed for the memory structures than I am concerned about?
