When we use credit scheduler in 64bit hypervisor, we see these issues: + Booting 32bit VMX domain hangs at "ACPI: Unable to locate RSDP". + Booting 32pae VMX domain will get a kernel panic. + Booting indows SP1/SP2 Guest will crash guest OS.

We don't see these issues with BVT scheduler.

Is this specific to 64b hypervisor? We do most HVM testing on 32b PAE and haven't seen these issues.
