If we define wrong values to a disk parameter in domain configuration
files, we get an error message or a guest OS panic.
1. If we define a wrong disk type, xm create command error occurs
about 100 seconds later.
e.g. disk=['xyz:/xen/root-vm1.img,hda1,w']
2. If we forget a disk type, a guest OS panic occurs.
e.g. disk=['/xen/root-vm1.img,hda1,w']

If we define the form of list of string to "cpus" parameter,
different CPU affinities are set for each VCPU as follows.
# grep cpus /etc/xen/vm1
cpus = ["2", "3"]
vcpus = 2
# xm create vm1
Using config file "/etc/xen/vm1".
Started domain vm1
# xm vcpu-list vm1
Name ID VCPU CPU State Time(s)
CPU Affinity
vm1 1 0 2 r-- 3.5 2
vm1 1 1 3 -b- 3.2 3
If we define the form of string to "cpus" parameter as before,
a same CPU affinity is set for each VCPU as follows.
# grep cpus /etc/xen/vm2
cpus = "2,3"
vcpus = 2
# xm create vm2
Using config file "/etc/xen/vm2".
Started domain vm2
# xm vcpu-list vm2
Name ID VCPU CPU State Time(s)
CPU Affinity
vm2 2 0 3 -b- 3.0
2-3
vm2 2 1 2 r-- 2.6
2-3

Solaris uses a simple indexing scheme for block devices. Parts of xend
translate them as hexadecimal (such as block-attach), and decimal, or
unconverted, elsewhere (such as block-detach). Harmonise these
interfaces by allowing decimal specifications.
Also allow Solaris-style block device names.

This patch embeds the ACM policy's schema in the python file where the

* SSL/TLS support is disabled by default, as other server did.
* If "xend-relocation-server-ssl-key-file" and
"xend-relocation-server-ssl-cert-file" exist, SSL/TLS is enabled
automatically.
* "xend-relocation-tls" is used by relocation client only.

CPUID's replies are now pre-calculated in libxc and given to the
hypervisor via a new domctl.
There are two parts to this feature:
- We can overwrite cpuid's replies.
- We can check that a vm is compatible with a host's processor.

When a domain wants to use a tap:ioemu disk but has no device model,
start a tapdisk-ioemu instance as provider. Also, move the creation
and removal of communication pipes to xend so that qemu-dm doesn't
need the unwanted SIGHUP handler anymore.

This patch extends the ACM binary policy format with an embedded hash
of the corresponding XML policy in order to tie them together. This
allows xend to determine whether it has the correct XML policy in its
repository and react appropriately if it does not have it.

If a hang-up of a guest OS occurs, we will restart the guest OS by
using
the following commands.
1. xm destroy
2. xm create or xm start
To reduce the number of xm commands to use, this patch adds a new
command. The command is "xm reset". The command executes destruction
of a domain, and then creation of the domain.

that our headers are not built with __GNUC__ and __STRICT_ANSI__.
__extension__ had some weird (and buggy) behaviours when nested which
make it a risky proposition for general usage in our header
files. Better to disallow -ansi, -std=c99, and similar gcc options
when building against Xen headers.
