moving a mac vm from parallels to virtualbox hangs

Fusion 8 takes a lengthy, but tolerable, 9 seconds longer to transfer our small files from OS X to the Windows VM, but an astounding 36 seconds longer (a 335 percent increase) when transferring from the Windows VM to OS X.

Things are mostly competitive for transfers within a VM, with Fusion taking about 2.5 seconds longer than Parallels, but when it comes to transfers between the host and the guest operating systems, things fall apart for Fusion. With small files, there’s no competition. When it comes to file transfers between the host and guest operating systems, the “To Host” test (a file transfer from the Windows VM to OS X) shows Fusion and Parallels to be about equal, while Fusion wins by about 3 seconds in the “To VM” test (a file transfer from OS X to the Windows VM).īut file transfer speed can vary greatly depending on the number and types of files, so we wanted to see what would happen if we threw a huge number (4,096) of small 4KB files at our VMs. In the “Within VM” test, which measures a transfer from one location on the VM’s virtual drive, Parallels beats Fusion by a little more than 1 second. Starting off with the large file transfer, we see that the platforms trade victories based on the type of transfer.
