Probably. With real hw, you'd power on after a disk install, right?

Subject: [Xen-users] lvm backed domU doesn't see bigger disk

Did you restart the guest or not?

You may find that if you "xm block-detach" and "xm block-attach" the
device, it will work, but if that's not working, then you'll need to
restart the guest.

Whilst an LVM is resizable, as your DomU isn't using LVM to manage the
volume, it's not seeing the size-change inside DomU (because it's
thinking that it's a standard SCSI/IDE disk, which aren't known to
change size once they have been installed in the system).
