Re: [Xen-users] Migrate existing Windows XP VirtualBox VM to Xen

[Felix Kuperjans <felix@xxxxxxxxxxxxxxxxxx>]

 Hi Juancho,

did you try setting acpi=1 and apic=1; I'm always using them with 
Windows XP, no idea whether VirtualBox is using it or not, but it could 
be the reason for this error.
When converting VMWare images, a usual problem is that VMWare uses SCSI 
for the primary device and Windows can't boot from IDE then, but in such 
cases you usually don't even see the Safeboot menu...
Hope this helps,
Felix
