sounds like you're doing something very wrong there, i use full disk encryption on my boot and vdi disks and never notice any performance decrease.lacis_alfredo wrote:Hi, I just tried using an encrypted partition in Ubuntu 10.04 host to host an XP guest. (I have several guests already, but hey are hosted in an unencrypted partition.)
I copied the guest using "VBoxManage clonehd ...." to the encrypted partition.
One small problem - when the Guest is booted, it tries to decrypt the whole 13Gb image first! It's been half-an-hour now, and it hasn't got to the "Windows XP Starting" screen yet.
Obviously this is not the way to do it. Any suggestions?
you sure you're not encrypting just the vdi file using pgp or truecrypt rather than the host disk itself using dm-crypt?
