Considering that this is an hvm guest and that you only have one disk,
it should be hda rather than xvda.
Also it is probably not a good idea to disable acpi.

this is an hvm guest so extra is not going to do much, you need to pass
these parameters directly to the guest kernel from grub if you want them.
