hd_write_verify
LBA tools(hd_write_verify & hd_write_verify_dump) are very useful for testing Storage stability and verifying DATA consistency, there are much better than FIO & vdbench's verifying functions. for example: physical disk: ide/sata/scsi/ssd/iscsi/fc/raid/...; virtual disk: loop/nbd/lvm/soft raid/...; VM disk: ide/sata/scsi/virtio-blk/virtio-scsi/...;
Kernel_VT
kernel & VT
kvm-dmesg
A tool designed to retrieve kernel logs from a guest virtual machine running under KVM.
qcow2-backup
qcow2-defrag
qemu-img convert command(eg: qemu-img convert -f qcow2 -o preallocation=off -O qcow2 src.qcow2 dst.qcow2) will lost snapshots of qcow2 image. qcow2-defrag is a tool for defragging qcow2 image which can solve this problem.
qcow2-delta
qcow2镜像合并工具、虚拟机磁盘克隆工具
qcow2-dump
qcow2-dump is a useful tool for checking and repairing damaged qcow2 image, it has some improvements compare with qemu-img check command (qcow2-dump has all functions which qemu-img check command has).
