To solve this problem, use "Convert virtualbox to xen" to search for two articles:

Method:
Vboxmanage internalcommands converttoraw mysimage. VDI/tmp/mysimage. img
Http://forums.virtualbox.org/viewtopic.php? F = 1 & t = 18560
Method:
Vboxmanage clonehd XYZ. vdi xyz. Raw -- format raw
Restart to a normal kernel (where a VirtualBox-3.12 is installed) and perform the following operations:
[WHB @ jcwkyl VM] $ vboxmanage clonehd/Vm/vm1.vdi/Vm/vm1_clone.img -- format raw
Virtualbox command line management interface version 3.0.12

Converting image "/Vm/vm1.vdi" with size 8589934592 bytes (8192 MB) to raw...
Then uninstall virtualbox (for fear that it conflicts with the xen kernel) and restart it to the xen kernel. After verification, there is no problem with the above two methods. The only problem is that the generated file is too large, in the past, vm1.vdi was only 987 m, but the vm‑clone.img and vm‑convert.img generated by the above two methods were both 8.1G!
