-blockdevdriver=qcow2,file.filename=/path/to/image,file.locking=off,file.driver=file 要检查映像锁定是否处于活动状态,请检查主机上“lslocks”命令的输出,并查看 QEMU 进程对映像文件是否持有锁。QEMU 实例可以锁定多个字节,其中每个字节都反映由正在运行的块驱动程序获取或保护的特定权限。 筛选器驱动程序 QEMU...
the raw disk image is a bit-to-bit image of a hard disk, similar to what you would get when executing the dd command on a block device in Linux. This format does not support thin provisioning or snapshots by itself, requiring cooperation from the storage layer for these tasks. It may,...
block_stream:将数据从后备文件复制到块设备中。 block_job_set_speed:设置后台块操作的最大速度。 block_job_cancel:停止正在进行的后台块操作(流操作、镜像操作)。 block_job_complete:手动触发正在进行的后台块操作完成。对于镜像操作,这将把设备切换到目标路径。 block_job_pause:暂停正在进行的块流操作。 block...

(one per virtual block device) to process I/O requests going through the virtio-blk driver. It makes use of Linux AIO (asynchronous I/O interface) support in the VM Host Server Kernel directly—without the need to go through the QEMU block layer. Therefore it can sustain very high I/O...
nbdcopy lets you copy from and to NBD servers (nbdkit, qemu-nbd, qemu-storage-daemon, nbd-server), local files, local block devices, pipes/sockets, and stdin/stdout. For example to stream the content of an NBD server: $ nbdcopy nbd://localhost - | hexdump -C ...
