Xen users - Feb 2013 - [XCP] recompiling xapi rpm changes version and licensing details.

Hi there. I needed to recompile xapi to fix a bug that was resolved regarding
vdi-create not setting the sharable flag. I used the sources provided in the
source-1.iso from xen.org. Everything is good in this regard, and creating a vdi
that has "sharable=true" is possible, but I had a problem that forced
me to revert to the older copy of the xapi binary because my XCP box was now
being identified as a XenServer box.

Here''s a screen shot:

The actual problem happened on a real host pool member that I had installed the
new RPMs. As I mentioned, I had to revert back to a backup copy of the xapi
binary because I could not start any of my VMs on that host. The error from xe
was:

There are no suitable hosts to start this VM on.
The following table provides per-host reasons for why the VM could not be starte
d:

DCSC-XEN03    : Cannot start here [Not enough free memory]
    DCSC-XEN01: Cannot start here
[Api_errors.Server_error("VM_HOST_INCOMPATIBLE_VERSION", _)]

My question is how do I go about modifying the version and platform information
for XAPI? My xensource-inventory file looks fine:

BUILD_NUMBER=''61809c''
SOFTWARE_VERSION=''1.6.10''
DOM0_MEM=''752''
MANAGEMENT_INTERFACE=''xenbr0''
INSTALLATION_UUID=''718e7db1-cf3d-46ea-bcc9-cee8c456ed4d''
COMPANY_NAME_SHORT=''xen.org''
PLATFORM_NAME=''XCP''
PLATFORM_VERSION=''1.6.10''
KERNEL_VERSION=''2.6.32.43-0.4.1.xs1.6.10.734.170748xen''
BRAND_CONSOLE=''a console''
COMPANY_NAME=''xen.org''
XEN_VERSION=''4.1.3''
PRIMARY_DISK=''/dev/disk/by-id/scsi-SATA_QEMU_HARDDISK_QM00001''
CONTROL_DOMAIN_UUID=''969c742c-9b46-46ca-85d1-7f7eb249d913''
MANAGEMENT_ADDRESS_TYPE=''IPv4''
BACKUP_PARTITION=''/dev/disk/by-id/scsi-SATA_QEMU_HARDDISK_QM00001-part2''
PRODUCT_VERSION=''XCP''
INSTALLATION_DATE=''2013-02-05 13:50:23.445194''


It is almost as if the new xapi binary doesn''t care about
xensource-inventory?

Hi Errol,

Our build system uses environment variables to inject the PLATFORM_NAME 
and PLATFORM_VERSION into the RPM. (See the Makefile snippet below). 
Before you do rpmbuild, you should do:

export PLATFORM_NAME=XCP
export PLATFORM_VERSION=1.6.10

You may also want to export a BUILD_NUMBER, but I don''t think that this
is used for anything so you can probably ignore it.

The interesting bit from Xapi''s Makefile:

.PHONY: version
version:
         @printf "(* This file is autogenerated.  Grep for 
e17512ce-ba7c-11df-887b-0026b9799147 (random uuid) to see where it comes 
from. ;o) *) \n \
         let git_id = \"$(shell git show-ref --head | grep -E ''
HEAD$$''
| cut -f 1 -d '' '')\" \n \
         let hostname = \"$(shell hostname)\" \n \
         let date = \"$(shell date -u +%Y-%m-%d)\" \n \
         let product_version = Util_inventory.lookup ~default:\"\" 
\"PRODUCT_VERSION\" \n \
         let product_version_text = Util_inventory.lookup
~default:\"\"
\"PRODUCT_VERSION_TEXT\" \n \
         let product_version_text_short = Util_inventory.lookup 
~default:\"\" \"PRODUCT_VERSION_TEXT_SHORT\" \n \
         let platform_name = \"$(PLATFORM_NAME)\" \n \
         let platform_version = \"$(PLATFORM_VERSION)\" \n \
         let product_brand = Util_inventory.lookup ~default:\"\" 
\"PRODUCT_BRAND\" \n \
         let build_number = Util_inventory.lookup 
~default:\"$(BUILD_NUMBER)\" \"BUILD_NUMBER\" \n \
         let xapi_version_major = $(shell cut -d. -f1 VERSION) \n \
         let xapi_version_minor = $(shell cut -d. -f2 VERSION) \n" \
         > ocaml/util/version.ml
