by access to 0xc000 port in VMX, qemu will blocked there until it
finished. And during that block, there are extra dom switches between
dom0 and idle domain, and VMX can't be resumed. By making real IDE dma
tranfer run in another thread, qemu will return and VMX resume on time
and there are fewer cycle wasted.

does not, which means that the backtick-enclosed arguments are evaluated
regardless of the success of preceding tests.

It now allows the user to configure what he wants to be done on
xendomains stop: sysrq, migrate, save, or shutdown.
For this to be safe, a timeout has been introduced (optional).
On start, saved domains may be restored, and not yet started
domains from the auto start dir will be started in addition.
status reports missing domains, restart and reload work as well.
The init script is somewhat SUSE-ish, but it should work on LSB
compliant and on RH based distros as well.
I would appreciate this to be put into tools/examples/init.d/

For domain migration, unless you use a rootless setup, you need
to have network storage available. For the poor people like me that
have no SAN, one easy possibility to have it is to use nbd.
Find attached the block-nbd script (in /etc/xen/scripts/) and
an example config file. The block-nbd script is based on the -enbd one.
They have been used successfully in the Xen Tutorial at Linux Kongress.

It doesn't make sense to undo the network configuration when stopping
xend since that would cut off all VMs from the network. Undoing the
network setup should be an option independent of xend stop.

means that any reads attempted on that tty will not cause handle_tty_read to
segfault looking for an interface that does not exist.
Move the writing of the tty node so that it happens after console/limit has
been read, as it is cleaner if the writing is the last thing that happens.

whether a domain has been introduced to the store. Added a separate message
XS_IS_DOMAIN_INTRODUCED and API for that (xs_is_domain_introduced) to determine
whether the domain has really been introduced. This change means that the
tools can determine the correct domain path earlier in the domain creation
process, which is particularly a factor with live migration, as it allows us
to create the devices earlier in the process, and unpause the new domain before
performing the introduce. Until recently we already had these features, but
the simplification of the interface between xend and xenstored caused breakage.
No longer clear out the domain path when a domain is introduced -- this was a
hack to work around the recent problematic semantics of GetDomainPath.
Do not write the contents of the info block to the store. All the configuration
info is written to the /vm path, and anything else in the info block is either
dealt with explicitly or is ephemeral and has no place in the store.

/local/domain/0/backend/<devclass>/<dom>/<devid>/error, write them instead to
/local/domain/0/error/backend/<yada>. This is not the best place for them
perhaps, but it moves them out of the backend directory, on which the drivers
have a watch. This fixes the problem whereby writing an error will trigger a
watch, causing the error message to be written again, and repeat. Fixes bug
#286.

enabled vcpus in a domain. This really isn't an issue anymore with the
changes made to dom0 ops and xm/xend.
But, I provide it because:
- Josh noticed my previous patch called getvcpuinfo twice for each vpcu,
which was completely silly.
- this patch would be useful in the remote chance that domain vpcus are
enabled out of order.

Change the interface between netback driver and vif hotplugging scripts. The
mac address and bridge details are read from the store directly by the script,
so that the kernel driver does not need to get involved.
Remove an awful lot of cruft from vif-bridge. Move the iptables handling into
