For SLES10 SP1 I would like to support some additional settings in
Xen_ComputerSystemSettingData. Attached is an updated mof. Notice I
removed some of the existing settings (most were commented anyway) such
as DHCP, Gateway, etc. These are very Linux specific and are just
appended to kernel args in xend anyway so they can be specified in
KernelOptions if needed. What do you think about the enums for
On[Poweroff|Reboot|Crash]? They are enums in Xen API and the values
were taken from the spec.
I think the Xen_Console and Xen_ConsoleSettingData classes Raj sent
earlier should suffice. Absence of an instance of
Xen_ConsoleSettingData on DefineSystem implies 'nographic', otherwise
protocol property will handle VNC, SDL, or text. We'll take the
defaults for all other VNC related settings found in a legacy config
file. I think the defaults are reasonable anyway, e.g. use the first
unused port >= 5900. Explicitly specifying a port seems problematic in
the event you move the guest to another host and the specified port is
already in use. Perhaps vncpasswd needs some thought. It could be
supported via the ConsoleConfigInfo property on Xen_ConsoleSettingData.
There is a corresponding dumping ground field on the Console class in
Xen API.
I think the important thing for console is being able to determine how
to connect to the guest once it is launched. The URI property should
contain the port to connect with a viewer when Xen_Console or
Xen_ConsoleSettingData is queried on a running guest.
BTW, any suggestions from SVPC on the console issue? Was there an
opportunity to discuss it on today's call?
Raj - one thing you could help me with is implementation of
ModifySystemSettings on class Xen_VirtualSystemManagementService. This
extrinsic is used to modify properties of
Xen_ComputerSystemSettingData. Probably not a lot in there that we want
to support modifying, but I could see users wanting to change the
On[Poweroff|Reboot|Crash] behavior, KernelOptions and perhaps even
Kernel and RAMDisk. I don't think we want to support modifying
Bootloader, BootloaderOptions, acpi, apic, pae, or localtime. Anyway,
take a look at Xen_VirtualSystemManagementService.c and search for
ModifySystemSettings. It currently returns CMPI_RC_ERR_NOT_SUPPORTED.

Jim
