In terms of physical hardware you can use any storage hardware compatible with Linux (which is almost everything). I think that's what you were asking. In terms of how the virtual disk appears to the operating system inside the KVM virtual machine, it may appear as a different kind of device, but that shouldn't be a problem. Note that with network storage protocols such as iSCSI you should be able to bypass the overhead of virtualising the hardware, and just connect to the storage device(s) directly from the guest over the virtual network(s), if the guest software supports that. However, I have no clue about the speed of iSCSI compared to other methods - I'm not trying to say "use iSCSI", I'm just trying to say "if you are going to use iSCSI, this is how you can use it". -- Robin At Wed, 3 Feb 2010 16:05:24 +0530, anuj rampal wrote:
