I printed the terminal attributes after openpty() and they were
garbage on the first console, valid on the second etc.
openpty() gets garbage in (uninitialized attributes MODIFIED by
cfmakeraw()). It sets the slave to the attributes requested. Using
uninitialized data for cfmakeraw->openpty results in pty attributes
that may even have the receiver disabled. Closing the slave just hides
the bug as these attributes disappear and hope the slave will be
reopened and initialized.

You can use "host" mode by specifying keyword "host" as virtual scsi
device. Following is usage example.
xm scsi-attach 1 2:0:3:4 host
In this case, all LUNs under host=2 are attached to guest domain 1.
The channel=0, target=3 and lun=4 are ignored.

In the case of xm scsi-attach, when the SCSI devices are specified in

If lsscsi command is not installed, the processing works by using

This patch adds a videoram parameter (4MB is the default) to pv guests
too: if the pv guest is actually a stubdomain then the videoram size
is added to the initial required available memory.
This way there is no risk that a stubdom fails to populate the
videoram because the RAM freed for the videoram by dom0 has already
been used to create the stubdom.

Since changeset 17617 the block device protocols are checked to be
either file or phy. This has later been fixed to also include
tap. This is still not a correct check as there can be arbitrary
additional protocols. Before this check was added you could have a
block-xyz hotplug script and xyz would work as a protocol, now it is
refused. An example for this mechanism is the block-nbd script which
is included in the tree.
This patch changes the check to allow file, phy, tap and all protocol
names for which a block-$protocol hotplug script exists. This should
fix the last regressions introduced by the check.

In c/s 19009 an incompatible change was made to the ABI of libelf-*,
which are included in libxenctrl and libxenguest. To avoid client
programs (such as python/lowlevel/xc/xc.so) picking up a wrong
version and perhaps crashing, the soname should be changed.
I have chosen the version number 3.4 as xen-unstable is currently the
pre-3.4 branch. I assume we don't care about API/ABI stability within
an unstable branch.

This patch allows core-dumping to work on a cross-bit host/guest
configuration, whereas previously that was not supported. It supports
both PV and FV guests. The core file format generated by the host,
needs to match that of the guest, so an alignment issue is addressed,
along with the p2m frame list handling being done according to the
guest size.
