IPL for guest

[Herald ten Dam]

When deploying a new guest the IPL is always the disk mentioned as boot disk (the one mentioned in zvmsdk.conf). In the profile always comes IPL 100 or so. This is nice but we want to call the profile exec in our environment so we can make use of vdisks for the guest for swapping. We like to call IPL CMS for example.
So we would like to see an option in the configuration (zvmsdk.conf) to set the IPL to a value or otherwise choose the boot disk. This way we have the flexibility to adjust our environment.

Thanks in advance

we have following code in each layer

        if (disk_list and 'is_boot_disk' in disk_list[0] and
            disk_list[0]['is_boot_disk']):
            ipl_disk = CONF.zvm.user_root_vdev
            rd += (' --ipl %s' % ipl_disk)

    if 'ipl' in rh.parms:
        dirLines.append("IPL %0.4s" % rh.parms['ipl'])

so I think you want an option like following?

if CONF.use_customer_ipl
     rd += (' --ipl %s' % CONF.use_customer_ipl)
else:
     rd += (' --ipl %s' % ipl_disk)

will CMS be the only option or you want something else ? Thanks

Hi,

as described is our intention. For us CMS will do, but there are many options for IPL in a profile, see the manual. But most use is a VDEV or CMS.

Thanks

I saw that the code was checked in. I downloaded the master and tested it. I created a guest and added the parameter "ipl_from". This works if it has only "cms" as value. We adjusted our situation and now we need besides "cms" also "parm autocr". I tested also with "ipl_from" set as "cms parm autocr", but got the error:
{
   "rs": 6,
   "overallRC": 500,
   "modID": 1,
   "rc": 4,
   "output": "",
   "errmsg": "Unexpected internal error in ZVM SDK, error: SMT internal error. Results: {'rs': 6, 'errno': 0, 'strError': '', 'overallRC': 4, 'rc': 4, 'response': [\"(Error) ULTGUT0006E MAKEVM's DIRECTORY subfunction encountered an unknown operand: parm\"]}"
}
So I think there is some error if there is more than 1 word in the ipl_from parameter.

Is it possible to fix?

Thanks in advance
Herald
