Thread-topic:	Mapping Pages between two HVMs fails

Hi!

I am running two HVMs (One is Cent-OS Linux HVM and the other is VxWorks HVM) and using Xen.3.3.0.

I need to share and map the entire Linux HVM’s memory to VxWorks HVM.

I am able to share the page frames in Linux side successfully but mapping them by their Grant References at the VxWorks HVM side is failing.

While mapping, it just reboots DOM 0 operating system which causes all the domains to get destroyed.

The PFNs (page frame numbers) I am using to share at the linux side starts from 0 (1,2,3,…301). The Grant references generated are 141, 142,…. 301.

While mapping the Gref 301 the system reboots. Do you have any idea why the mapping reboots the system specifically for the 301 Gref number.

Any help is appreciated. Thank you.

Regards,

Prashanth
