Hi Fellas!

 I'm trying to explore the possibilities of PVSCSI, as for example, online resize, look:

At the Debian Lenny dom0 with Xen 3.3.2 and Linux 2.6.18 compiled from xen.org:

1) lvcreate -L 10G -n guest01-root HyperVG01;
2) configure the guest01 PV domU with PVSCSI using HyperVG01/guest01-root as partition, not as virtual disk;
3) start guest01;
4) lvextend -L +15G HyperVG01/guest01-root.

 Should I need to reboot the domU to be able to use this +15G? Or the resize is online?!

 If yes, the resize can be done online, what happens if I put the iSCSI target/client between the LVM and PVSCSI, the online resize will still be available?
