I am experiencing very weird and hard to debug issue for me with live

responds to echo requests (for some time). When I am trying to 'ping'

This patch contains the following two changes:
1. Fix the bug in nested preemption timer support. If vmexit L2-L0

be save in such exits.
2. Add support of Save VMX-preemption timer value VM-Exit controls

With this patch,

1. Save preemption timer on VMEXIT if relevant bit set in EXIT_CONTROL
2. Test a relevant bug of KVM. The bug will not save preemption timer
value if exit L2-L0 for some reason and enter L0-L2. Thus preemption

Thanks, I'll try that. Do you know of any way to get at the VCPU
structure from another process? I'm looking to have an event triggered
from the guest which will notify my application. In Xen I use an event
channel, and then I can call a function to retrieve the relevant VCPU
context.

I did not reproduce the bug fixed in [1/2], but there are not that many
reasons why we could not unload a module, so the spot is quite obvious.

'.done' is used to mark the completion of 'async_pf_execute()', but
'cancel_work_sync()' returns true when the work was canceled, so we
use it instead.
