I believe there are some experimental features in VirtualBox so that it can use an iSCSI initiator to attach storage. The guests see ordinary storage, the storage is actually an iSCSI target, I guess I am getting off-topic on the original request though.On Wed, Apr 25, 2012 at 17:43, Boris Epstein <[email protected] <mailto:[email protected]>> wrote:Fernando, thanks! How would I do that? Since you didn't specify what is your guest OS, it's difficult to say. I assumed you were trying to use a Windows based OS as guest. In that case you could install Microsoft's iSCSI initiator http://www.microsoft.com/download/en/details.aspx?id=18986 I had something like this in mind http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Virtualization/sect-Virtualization-Shared_storage_and_virtualization-Using_iSCSI_for_storing_virtual_disk_images.html But the above docs are for KVM, not Virtualbox.I never attempted the above approach, I was just thinking aloud about a possible workaround to any VBox disk image size limits.. somebody else might have to jump in...Much simpler could be to do network shares between host and guest....
But yes, if you wanted more than 2TB storage, present multiple 2TB storages as individual disks and set them up in the guest OS to provide you with the required capacity (dynamic disks in Windows, LVM volumes ? in Linux). Your limits then would be that of the guest OS to amalgamate the 2TB disks together, not the restriction of VirtualBox.
If we're entering the realms of > 2TB then I think it might be better to find a in-guest way of attaching the storage rather than virtualise it.
The host side iSCSI is in the manual - http://www.virtualbox.org/manual/ch05.html#idp11829536
