init-scripts there are much "sleep x", and every "x" were "2*x" in
reality.
other tasks are also much faster
i'm happy now :-)

KVM: cleanups on user/kernel irqchip checking
The patch removes the union of userspace irq_pending and kernel apic in
struct vcpu, which minimizes the impact of careless overwriting and
avoids accidentally dereferencing invalid apic pointer.
It also adds a protective checking on KVM_INTERRUPT ioc

Hi All,
I am working on some PV stuff and had some questions about the ability
to share memory across the Guest/Host boundary.
It seems that most examples of how to do this always involve starting
with a *page, converting it to a gfn via page_to_gfn(), and using that
as a gpa to pass across the

It was tr that was affecting Workstation, since we boot through normal
BIOS path, and only a 16-bit task was loaded at this point.

For some applications (e.g. qemu launched by libvirt) it's much easier
to just pass a filename on the commandline than to feed data via
stdin.

Thanks for the patches.
There is still the mystery of different file sizes for different
migration-exec commands, all files are "valid saved image".
It seems to me that some unmodified pages are being marked as dirty, and
are being saved twice (and later loaded twice).
I'm still chasing that.
Avi,

kvm: qemu: fix in-kernel APIC timer saving
This patch fixes a bug that APIC timer is disabled when migrating from
