Hi everyone,

Just a quick question:

Is there a limit on the vbd size for pv guest domains, I've found only
rumors on the Internet about a 2TB limit, but from my experience with
xen-3.0.3 /linux-kernel-2.6.18-5 (installed from a debian etch packages)
I can say that a lvm volume of 3.7TB as created and formated in Dom0 is
seen as 1.85TB only of course reporting a corrupted xfs filesystem
ending after the end of the device. If there is any xen/kernel version
where this limitation disappears please tell me.

Thanks in advance

Geza Gemes
