starts up, in order to find the VNC password.

returning the error to the caller.
None of our vmcs reads/writes should fail. In fact many callers were
ignoring failures, which can hide bugs (in fact it hid one in
vmx_restore_dr(), which was incorrectly using __vmread() before
the vmcs was loaded).
__vmread_safe() is used by the vmcs dump function, which is the only
function which can legitimately fail a vmcs access.

domains to appear, if an existing domain reboots itself. In this case, we
need to get the list of running domains from Xen again.

- makes it more apparent that 'xm mem-set' has no effect on HVM's.
- show's that memory is changing if 'xm list' is issued while guest is
ballooning (w/o touching balloon driver)

This required fiddling the asm constraints of the atomic bitops. It
seems gcc isn't entirely happy with "+m": the manual says that the
'+' modifier should be used only when a register constraint is
available.

This simplifies the IRQ logic significantly and avoids the bogus
hvm_pic_assist() on domain resume path.
There is more work to be done here. At least:
1. set-irq-level should really be set-interrupt-wire-level. Wire
state needs to be distinguished from PIC (in particular, PIC IRR)
state.
2. Hypercalls can be batched in qemu and pushed down in one
multicall.
