[Xen-users] Xen block device online resizing

[sstan <sstanisi@xxxxxxxxx>]

Hi,


I'm using SLES11 sp2 both on Dom0 and DomU. The kernel is > 3.0 and Xen 
4.1 is installed.
Online resizing has become a feature not too long ago with XEN. It 
allows one to expand the disk's capacity without having to restart DomU.
I tried to use that feature, but when I append memory to my virtual 
block device in Dom0, it is not registered by DomU. I have to either 
reboot or live migrate in order to achieve a disk resize. I tried to 
load some modules with modprobe, but it didn't work. Has anyone been 
able to achieve an online resize? I should mention that modprobe in DomU 
doesn't "see" the additional capacity.
Thanks,

Stefan
