In the stubdom case you can now specify sdl=1 and vnc=1 (again, both
can be selected at the same time) in the vfb configuration.
So instead of:
vfb = [ 'type=vnc' ]
now you have:
vfb = [ 'vnc=1,sdl=1' ]
the former configuration option is deprecated but still supported for
backward compatibility.

D3hot state in some PCI devices causes the failure of domain
creation/destruction.
The default is "pci_power_mgmt=3D0" which disables the guest OS from
managing D-states because it would be better to avoid the trouble than
advantage of low power consumption.

This patch adds a per-domain flag to specify whether a domain will be
S3 integrity protected when Xen is launched using tboot/TXT.
The tools now support an integer domain configuration parameter called
's3_integrity', which defaults to 1, to enable S3 integrity protection.
The struct arch_domain structure has been extended to have an
's3_integrity' field that represents this setting.

Add a new parameter to DOMCTL_bind_pt_irq to allow Xen to know the
guest physical address of MSI-X table. Also add a new MMIO intercept
handler to intercept that gpa in order to handle MSI-X vector mask
bit operation in the hypervisor. This reduces the load of device model
considerably if the guest does mask and unmask frequently

1) PCI_PM_CTRL_NO_SOFT_RESET: this is bit3 of PMCSR(Power Management
Control/Status). It should be 8. This bit means a device's capability
of not doing an internal reset across D3hot/D0.
If the bit is 1, there shall be no reset across D3hot/D0, so we should
not use it as a method to reset device.
2) When performing reset using standard FLR methods, we should sleep
at least 100ms; in current code, it's incorrect somewhere we sleep
0.2s and somewhere 0.01s.
3) In detect_dev_info(), fix a typo: PCI_EXP_TYPE_PCI_BRIDG ->
PCI_EXP_FLAGS_TYPE.
4) fix a small typo in the comment of transform_list().

Problem: Handling requests for one connection can not only zap the
connection itself, due to socket disconnects for example. It can also
zap *other* connections, due to domain release requests. Especially
it can zap the connection we have saved a pointer to in the "next"
variable.

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.

device. Following is usage example.

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.
