[libvirt-users] Blockpeek.. A little help please
Hi, I'm trying to use blockpeek to open the contents of a file. Inside the vm i ran debugfs: imap /test/findme and got: inode 32642 is part of block group 4 located at block 131074, offset 0x0100 I try using 0x100 or 256 as the offset to blockpeek into that VM and get nonsense as a result. Am I calculating the offset incorrectly, is there a better way to find a file's location on disk? And then open it? I'm just printing the return as a string from the buffer looping over size. Is that incorrect? Thanks again, Steve

Oh, hey, sorry--I totally forgot to respond to your earlier email. Would libguestfs possibly be a fit for what you're trying to do? http://libguestfs.org/ Dave
