[TOOLS] Clean up routed vifs quietly on domain destruction.
I have experienced that the vif-route script does not work as expected
when deleting a virtual interface (Redhat FC5). Both of the commands
"ifdown" and "ip route" cause an early vif-route script exit and
therefore will cause skipping of the later script commands (such as
cleaning up iptables entries for the default 'antispoof'). The
vif-route
script creates the following syslog error entry:
"/etc/xen/scripts/vif-route failed; error detected."
It appears that both of the problematic commands are actually
redundant
when destroying domains:
1. the interface is already gone (I assume because the domain frontend
is gone already) --> ifdown does not do anything
2. the route is gone as well since the interface has disappeared -->
ip
route del does not do anything
Executing those redundant commands with "do_without_error" ensures
that
the script completes and cleans up iptables rules. The attached
RFC-patch only masks those commands when bringing down an interface,
so
that domain creation continues to fail in case of vif setup problems
(intended behavior).
Having the iptables cleanup called correctly by vif-route is important
to keep the iptables rule-set clean, otherwise antispoof rules
accumulate with every vif creation.

Replace dom0_ops hypercall with three new hypercalls:
1. platform_op -- used by dom0 kernel to perform actions on the
hardware platform (e.g., MTRR access, microcode update, platform
quirks, ...)
2. domctl -- used by management tools to control a specified domain
3. sysctl -- used by management tools for system-wide actions
Benefits include more sensible factoring of actions to
hypercalls. Also allows tool compatibility to be tracked separately
from the dom0 kernel. The assumption is that it will be easier to
replace libxenctrl, libxenguest and Xen as a matched set if the
dom0 kernel does not need to be replaced too (e.g., because that
would require vendor revalidation).
From here on we hope to maintain dom0 kernel compatibility. This
promise is not extended to tool compatibility beyond the existing
guarantee that compatibility will not be broken within a three-level
stable release [3.0.2, 3.0.3, etc.].

[qemu] hdparm tunable IDE write cache for HVM
qemu 0.8.2 has a flush callback to the storage backends, so now it is
possible to implement hdparm tunable IDE write cache enable/disable for
guest domains, allowing people to pick speed or data consistency on a
case by case basis.
As an added benefit, really large LBA48 IOs will now no longer be broken
up into smaller IOs on the host side.
