Xen devel - Mar 2008 - Migrate/Save of 32-bit domU Broken on Xen 3.2.0 64-bit dom0

Hello,

I try to save/migrate 32bit DomU under 64bit Dom0 but the DomU is 
unreponding after the command "xm save web-test  /tmp/web-test"
The 32bit DomU kernel was compiled on the 64bit Dom0 with XEN_TARGET_ARCH = 
x86_32 and XEN_TARGET_X86_PAE = y and it work without problem.

Is this feature working on Xen-3.2.0?

Any help would be appreciated!
