You're right on time..
One thing that would make my life easier going forward would be if we
could
separate out the interrupt related state from the [gs]et_sregs() calls.
What I propose is that we make two new calls (say [gs]et_pic). For

Hi
How do I get status of a VM ? What states are
available ?
running, stopped/paused, shutting down, blocked,
starting ?
For some of these states you'll need an agent running within the guest
{starting, shutting down}.
Note that currently except for virt-manager/libvirt there is no open

However, TPR can be set by the CPU using both MOV to CR8 as well as an MMIO

This is strange.
Just tested it again with kvm-24
The pointer is not released on ctrl del.
When the guest system reboots the system does not hang anymore though.

hi,
What is the status of paravirtualization?
It's basically stalled.
However, I'd like to restart this, on a much bigger scale. Using
paravirt_ops, one can use direct paging (like Xen) instead of shadow
paging, and achieve better performance. In fact, it should be
