sudo ./convert_disk.sh -i ubuntu.qcow2 -f vmdk -o ubuntu.vmdk 📌 直接写入物理磁盘 sudo ./convert_disk.sh -i backup.img -f raw -o /dev/sdb ⚠️注意:写入/dev/sdb之前,脚本会要求用户确认,以防误操作! 🎯 适用场景 ✅跨虚拟机平台转换磁盘格式(KVM、VMware、VirtualBox) ✅将raw压...
qemu-img create -f raw /data/images/centos01.raw 10G 1. 输出Formatting ‘/data/images/centos01.raw’, fmt=raw size=10737418240 以上是raw镜像格式创建虚拟机磁盘空间,推荐使用qcow2 raw “raw” 镜像格式是最简单的,并且是被 KVM 和 Xen 原生支持的格式,你 可以想象裸格式镜像和块设备文件是二进制位...
根据man qemu-img中最后内容提示,支持的文件类型有:除了raw qcow2,还有以下格式: 格式说明:vmdk ,vdi vhd,vhdx 大家想必很熟悉了,raw是通用格式,qcow2是qemu主推的格式,qemu推荐使用raw和qcow2以获取更好的performance 留坑:-B参数如何使用???
Raw virtual machine images are not compressed at all, so this command will actually create a full 10GB file, unlike before. You can convert it back toqcow2format for use with QEMU by reversing the syntax from the last step: qemu-img convert-fraw ubuntu-desktop-22.04.img-Oqcow2 ubuntu-d...

根据实际使用量来占用空间，但是和qcow2不同，raw需要宿主机支持hole（比如ext2，ext3，ntfs等）；能够调节空间最大值；能够直接被宿主机挂载，以传输数据；由于采用直接写文件的方式，性能高于qcow2；注：由于raw格式是qemu-img创建磁盘的默认格式，所以如果不指定文件类型的话，默认是raw。
