Attempting to run a Windows XP Pro x64 image created with a previous version of VirtualBox fails by either hanging or BSOD. Attempts to reboot in Windows Safe Mode causes either the vm to hang after loading the C:\windows\system32\acpitabl.dat, or the BSOD with a registry error.
VirtualBox advanced settings: enable ACPI checked, enable IP APIC checked, enable VT-x/AMD-V checked, enable nested paging not checked, enable PAE/NX checked, IDE controller type PIIX4.
Guest Additions installed on the guest image are version 2.1.4.
The Host is Windows Vista Ultimate 64.
I noticed that VirtualBox 2.2.0 now offers a single installer for both i586 and x64 -- have there been any issues with the proper files being installed for the correct version of the host OS?
