virtualbox

VirtualBox works good when you use the same VMs all the time. It organizes the disk images in one directory and the configuration files in another. It kees a record of all known disk images and virtual machines.

If you try to carry a VM around with you on an USB stick or want to put it on an encrypted image, then you will get trouble.

As Constantin suggested, here is a list of services, which my home server should provide:

To mount a shared folder in a OpenSolaris guest in VirtualBox, you have to install the Guest Additions and then mount the file system type vboxfs. The Usage is:

mount -F vboxfs <share> <mountpoint>

If you want to share the filesystem /share from the host to the guest, then first create the share. Go to “Shared Folders” in the Virtual Machine's Settings and click the little folder with the green plus on the right.
