[Xen-API] problem accessing lvmoiscsi vhd : libvhd::vhd_validate_footer: invalid footer cookie:

[Denis Cardon <denis.cardon@xxxxxxxxxxxxxxxxxxxxxx>]

Hi everyone,

this is my first post on this list, I hope I won't be off topic (Dave 
Scott's last post make me think that VDI issue are covered here).
I think I have a VHD that has been victim of the bug covered in the 
Hotfix XS56EFP1006 (http://support.citrix.com/article/CTX129267). I've 
attached a /var/log/xensource output below.
I'd like to know what are the option to get the data in that VDI? Is it 
possible to apply the fix on a XCP 1.0 pool? (2 servers, storage on 
lvmoicsi).
Thanks for the help,

Denis
