Current limitations and known problems:
- 64 bits SMP guests not supported on 32 bits hosts
- 32 bits SMP guests on AMD CPUs have very poor performance
- 32 bits SMP guests on certain Intel CPUs have very poor performance (few models though)
- the new registration dialog sends login and password information unencrypted/as plain text. Keep in mind when choosing a password! (will be fixed in a next beta)
Please do not report when you encounter these issues yourself. We are aware of them.
