There's need for free vtd_mem more memory for guest with
xen-unstable c/s 17529. This memory is freed when guest is
created, but is not freed when guest is restored. So restore
guest fails due to not enough of memory for guest.
Following patch uses same calculation of memory to free in guest
restore as is in guest creation.

For managed domains in state 'halted' I always get default values
for cpu_cap / cpu_weight after xend restart.
This is because the names of parameters differ between a SXP file to
create a VM (here the parameter names are cpu_cap / cpu_weight) and
a SXP file of a managed VM (here vcpus_params (cap 0) (weight 0)).
But XendConfig.py reads only cpu_cap / cpu_weight and if not found,
default values are used.
The patch reads first vcpus_params (cap, weight), if not found then cpu_cap,
cpu_weight and if both parameters are missing it uses the default values.

The following is the process of booting a DomU with 'mounted-blktap2' (VHD
for example) and 'pygrub' as bootloader:
1. Connect boot-device to Dom0 as '/dev/xpvd'
2. Pygrub get info for load DomU
3. Disconnect boot-device from Dom0
4. Boot DomU
During step 3 the created device is disconnected from Dom0, but
xenstore does not scrape away after the device is disconnected so you
get the following error:
"Error: Device /dev/xvdp (51952, tap2) is already connected."
During step 3 xend calls destroyDevice always with 'tap' as argument.

We have pscsi device with long scsi ids like 15:0:11:101.
In this case lsscsi prints no "blank" between id and type,
so the following split of the string returns wrong output.
The field physical_HCTL is set to 15:0:11:101]dis.
The patch replaces char "]" by "] ", so split() will return the right
physical_HTCL.

Xend-API defines the method VM_set_actions_after_crash with valid
action names coredump_and_destroy, coredump_and_restart,... . These
values have to be converted into internal representation
"coredump-destroy", "coredump-restart", ... otherwise start of the

On server startup xend start or a later xend restart needs approx. 30 min to
start/restart. Without attached FC devices xend start/restart needs only some
seconds.
server type: Fujitsu Primergy RX600-S5
The time gets lost in xen/xend/XendNode.py line 329 while calling
vscsi_util.get_all_scsi_device().
329 for pscsi_record in vscsi_util.get_all_scsi_devices():

I think, in most cases we don't need all the PSCSI devices registered in
xend, but only a few of it.
So a good solution for this perforamce issue is to scan only the SCSI device
paths we need, controlled by a new option in xend-config.sxp.
I have made a patch to allow specification of scsi devices we need in xend
in the config file xend-config.sxp.
The new options pscsi-device-mask expects a list of device ids oder partial
device ids like the option of lsscsi, e.g.
(pscsi-device-mask ('<partial-dev-id1' 'partial-dev-id2' ...))
Without this option set in xend-config.sxp or if lsscsi is not support, all
device paths are process like today.

add a command "domstate" to get the state of Vms, which may have one state of
{'shutoff', 'idle','shutdown','running','crashed','paused' or 'paused by
admin"}.
For case of pause, I distinguish it into two conditions. One is "paused" the
other is "paused by admin".
"pasued by admin" means that users pause a domain voluntary by "xm paused
VM" or " API"

In XendDomainInfo.py device_create function, when device type is
"vif", it has a paragraph to check the validity of "mac"
address. Before checking validity, device_add has been done. But after
checking validity, if the mac address is invlid, it raises VmError and
exits directly without doing clean work like removing the device item
from config info. This will cause that the incorrect mac address is
saved into VM Config file and VM fails to restart. If check "mac"
validity before doing device_add, there will be no problem.

If a command hold domains_lock, "xm list" would hang for waiting for
the lock. Such as creating many VMs at a script (such as 20), command
of "xm list" could hang for long time(10 mins). I think domains_lock
here only protect update(). So, we shouldn't do update before command
of "list" really get this lock, but xm do need show the domain's
information quickly. In this patch, if command couldn't get the
domains_lock after 20 times trying, "xm list" would show the
information of VMs without update().

This patch eliminate the global variables in libxenctrl (used for
logging and error reporting).
Instead the information which was in the global variables is now in a
new xc_interface* opaque structure, which xc_interface open returns
instead of the raw file descriptor; furthermore, logging is done via
xentoollog.
There are three new parameters to xc_interface_open to control the
logging, but existing callers can just pass "0" for all three to get
the old behaviour.
All libxc callers have been adjusted accordingly.
Also update QEMU_TAG for corresponding qemu change.

Add a new feature for xend-relocation-address option to support
definition by interface name which can be useful for people having
e.g. a cluster environment with multiple network interfaces on all of
the machines with only one reserved to be registered to a private
cluster network. This way they won't need to specify the relocation
address manually on all the machines but just simple providing the
interface name to get the IP address from would do the job (all the
machines have to have this interface named the same to make it
working, of course).
Technically it reads the interface name and gets its IP address using
ioctl call of SIOCGIFADDR and if the interface doesn't have the
address, i.e. if non-existing interface or hostname was provided the
original ifname is returned to preserve the old behaviour.
