After the physical machine is migrated to the virtual machine, it cannot enter normally.

After a physical machine is migrated to a virtual machine, it cannot normally enter-Linux general technology-Linux technology and application information. The following is a detailed description. In the afternoon, after I migrated the original AS from a physical machine to a virtual machine, the disk type changed to sda, which was originally hda.
The grub file does not need to be modified. After being directly guided from sda1, FSCK appears, but it cannot be detected. The reason is that all partitions in FSTAB are mounted as hda1, hda2, and so on, but in fact, these device files are no longer available. Instead, they are replaced by sda1 and sda2, which cannot normally enter the system. Instead, they can only be directed to the file repair mode. Run the mount command to view the files, all objects are mounted incorrectly in hda123 and should actually be sda123. How can I modify them at this time?
