but anyway, we provide good enough documentations, so if one wants to use "direct" mode, he can still change the xml to use it, any big problems here? though defaulting to "direct" is more convenient for these users.
Defaulting to "direct" is *NOT* more convenient for all users, only those who happen to have a new enough QEMU, from a vendor who actually decided to compile in the iSCSI support. If they're lacking such a QEMU then the "direct" mode will prevent the default config from even starting. This can never be an acceptable default choice. mode="host", while it huas some limitations in features, is the only option that is capable of working with any QEMU
s/limitations in features/possibility of wreaking havoc to clusters/ Didn't you "break features that worked" when you started forbidding migration unless cache=none? This time there is even hardly a feature that worked, because the feature is new. Paolo
