I am running XP guest on Karmic / 2GB AMD 2x4400+ with Samsung-SSD.
I suspected the filesystem (ext4) but on XFS, nilfs and btrfs it is all the same: XP guest loads for AGES... unusable...
However, for me it is worse when virtualisation is turned off.
When the system is otherwise idle, disk throughput alternates between 3 MB/s and 150 k periodicalle every other second (according to gkrellm). The SSD can deliver 250 MB/s - so I suspect some probs in the way Virtualbox 3.0.10 accesses disks.
(Or the Koala?) No difference between "IDE" and "SATA" mode for the guest emulated controller.
Will leave my phenom-hosted virtual machines on jaunty until this gets clearer.
