qemu probably needs some sort of --verbose or --debug option for when
you really want to see everything that's going on.
In the meantime, this patch removes some debugging messages when KVM
is not available.

From: "Richard W.M. Jones"
When using qemu -machine accel=kvm:tcg, if KVM is not available you
get a load of debugging output:
Could not access KVM kernel module: No such file or directory
failed to initialize KVM: No such file or directory

Introduce pci_config_read/write helpers to split up config space
accesses that are not length-aligned. This particularly avoids that each
and every device needs to check for config space overruns. Also move the

This patch creates a migration bitmap, which is periodically kept in sync with
the qemu bitmap. This allows us to have a separate thread for VM migration. A
separate copy of the dirty bitmap for the migration avoids concurrent access to

This patch implements a migration clock, whose implementation is similar to the
