RE: [Xen-users] Viewing core dump from Windows XP HVM
Jon,
The file size is:
-rw------- 1 root root 546209864 Jan 15 10:43 core
I've allocated 512MB to the XP HVM domain (dom0 is standard XenLinux).
Here is the output when I attempt to run GDB:
[root@localhost xen]# gdb file core

"/var/log/xen/core" is not a core dump: File format not recognized
If I run the file command on the core, I get:
core:ELF 64-bit LSB core file AMD x86-64, version 1
