Re: [Vol-users] Analyzing memory from a QEMU snapshot

Hi, I was provided a suspend-to-disk snapshot image along with a copy of the virtual harddisk file from a QEMU/KVM-based Linux server for analysis. Analysis of the harddisk is done. Now I'd like to dump running processes etc. from the server's memory image. I loaded the snapshot into QEMU and used the QEMU monitor to dump a memory image using the 'dump-guest-memory' command. So now I have this: memory.img: ELF 64-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style Then, I set up a fresh VM with Debian Linux in the same version the virtual server was running. Next, I installed the kernel image and related files extracted from the virtual harddisk on this new VM to get a Linux system running exactly the same kernel version. On this VM, I created a Volatility profile using the files provided in /tools/linux/. Unfortunately, Volatility crashes when running imageinfo on the dumped memory image file: ========================================================================= $ python vol.py imageinfo -f /path/to/memory.img Volatility Foundation Volatility Framework 2.5 INFO : volatility.debug : Determining profile based on KDBG search...
