Xen devel - Apr 2012 - xe vdi-create failure ot local SR type=file and type=ext

Hi,
have permanent failure when try to create VDI on local SR type=file or
type=ext. On both types it failed with the same error:
SR_BACKEND_FAILURE_78
VDI Creation failed [opterr=error 127]

I am on Debian box with kernel 3.3.0-rc7, Xen version 4.1.2 (Debian
4.1.2-2.1), Xen-API Version: 1.3.2-4 (Kronos)

Is it a bug, or am I missing something? Anybody managed to workaround
this problem?
