When injecting a floating interrupt and no CPU is idle we
kick one CPU to do an external exit. In case of I/O we
should trigger an I/O exit instead. This does not matter
for Linux guests as external and I/O interrupts are
enabled/disabled at the same time, but play safe anyway.

Hi,
I notice that Qemu supports dump virtual memory of Guest OS. As this
page suggests:
http://doc.opensuse.org/products/draft/SLES/SLES-kvm_sd_draft/cha.qemu.monitor.html
To save the content of the virtual machine memory to a disk or console
output, use the following commands:
memsave
Good questions.
One thing that prompted this code is the presence and proliferation of
architecture specific hypercalls in include/uapi/linux/kvm_para.h.
I'm not sure why the tree has continued on for as long as it has with
a list of reserved hypercall indices -- most of which are unused on
