Reading the Xen Core Dump File - How to deal with unsigned longs

[Puneet Lakhina]

Hi,

Im trying to read the coredump file of a xen domain, and Iv noticed a
few types includes in the file like vcpu_guest_context[1] use unsigned
longs, the size of which is system dependent. But I am uncertain as to
whether this depends on the dom0 the dump was taken from or whether it
depends on the hypervisor or whether it depends on the dump domU. The
reason I am asking this is because I am running Xen in an environment
where the dom0 is 32 bit and the hypervisor is 64 bit, and the domUs
whose dumps I am analyzing are 64 bit.

Thanks
