Is it possible to isolate all the VMs ( which is using qemu/kvm ) disk read/write requests in vfs_read/vfs_write, blk_start_request/blk_account_io_completion of the host system kernel?
Also, VM disk is basically an img file on the host file system, so another way to look at the above question is, can we hook ebpf on inotify ( http://man7.org/linux/man-pages/man7/inotify.7.html) events to watch img file read/modify accesses? Regards, zaafar <[email protected]> <[email protected]>
