can't use copy/duplicate of virtualdisk ( vdi )

[edisoemartono]

why we can't used copy of virtualdisk ( vdi file ) so we can use directly same os ( two same os ) on same time with different name for networking on them

copy the file vdi could but can be use as new/different one because properties said identically

its not like microsoft virtualpc that i used before where i could copy virtualdisk as much as i want and used it on the same time ( for networking test between them )

Use

VBoxManage clonevdi

to copy the vdi or

VBoxManage internalcommands setvdiuuid

to change the UUID of a vdi file after the file was copied.
