Subject: [Xen-ia64-devel] [Xen-ia64][PATCH]Fix incorrect NVRAM saving ifdomain destroyed by error configure

 

Nvram saving is always executed whereas domain destroyed by an error configure parameter. In this case, Nvram saving function will get a wrong address where NVRAM data located by GFW and save garbage data into NVRM file. Configure a wrong “vif” parameter can expose this issue.

 

This patch fix the issue by adding an address check function in NVRAM saving path.
