Please try to use this flag: action = params.Action(use_sysprep=True) vm.start(action) Nice, use_sysprep=True did the trick! I noticed also the flag use_cloud_init, I guess with same logic.

I think that you are doing things correctly. Did you take into account
that the sysprep logic is triggered only the first time that the VM is
started? In later starts the sysprep logic is just ignored. Try to
remove the VM and create it again, then start it with a simple script.
I'm using this:
#!/usr/bin/env python
from ovirtsdk.api import API
from ovirtsdk.xml import params
api = API(
url="https://ovirt.example.com/ovirt-engine/api";,
username="admin@internal",
password="**",
ca_file="/etc/pki/ovirt-engine/ca.pem"
)
vm = api.vms.get(name="myvm")
initialization = params.Initialization()
vm.set_initialization(initialization)
vm.update()
action = params.Action()
vm.start(action)
api.disconnect()
This works correctly in my 3.5.0.1 environment.
If you don't want to create the VM again you can also change the
"is_initialized" flag in the database (this isn't currently possible
with the RESTAPI):
# psql --host=localhost --user=engine --password engine
Password for user engine: **
engine=> update vm_static set is_initialized = false where vm_name='myvm';
UPDATE 1
engine=> \q
(The database password is in
/etc/ovirt-engine/engine.conf.d/10-setup-database.conf).

Is the operating system of the set to one of the Windows variants? If it
isn't set to a Windows variant then the Sysprep logic won't trigger. To

The problem is that using non persistent payloads isn't currently
supported, so basically your "payloads" element is silently
ignored. You
have currently two alternatives:
1. Use persistent payloads:
vm = vms.get(name="myvm")
vm.set_payloads(paylaods)
vm.update()
vm.start(params.Action())
You may also want to remove the payloads once the machine is
configured,
but this isn't strictly required, as Windows will not try to locate
the
sysprep floppy in subsequent boots. The only minor inconvenient is
that
the users of the VMs will see the floopy and its content attached.
Yes, this is exactly the workaround I'm currently using, and I have to
hide floppy via AD group policy (sysprep.inf contains administrator
password).
2. Use the builtin sysprep files (they are in
/usr/share/ovirt-engine/conf/sysprep):
vm = vms.get(name="myvm")
initialization = params.Initialization()
vm.set_initialization(initialization)
vm.update()
vm.start(params.Action())
This has the advantage that the sysprep floppy will be attached to the
VM only the first time it is booted. In subsequent boots it won't be
attached.
Great hint, I'll take a look into those syspreps to see if they fit for
my setup.
In 3.5 you will also be able to use sysprep support with your custom
file:
vm = vms.get(name="myvm")

Bug 1145999 has target release 3.6. That means that the team responsible
for fixing has studied it and decided to fix it for version 3.6. Note
that this is just a plan, things may change depending on the workload
and urgency of other bugs. I'd suggest that you comment on the bug that
you are interested on this fix, so that it gets a bit more priority.

As you can see, for debugging purpose, I print my xml action, and I get:

foobar.txt
This is file content

(ps -ef | grep qemu-kvm | grep vmname) I can't see -drive option
referring to floppy (I only see 2 "-drive" options, referring to vm
system disk and to a correctly mounted cdrom ISO)
What I'm doing wrong?

The problem is that using non persistent payloads isn't currently
supported, so basically your "payloads" element is silently ignored. You
have currently two alternatives:
1. Use persistent payloads:
vm = vms.get(name="myvm")
vm.set_payloads(paylaods)
vm.update()
vm.start(params.Action())
You may also want to remove the payloads once the machine is configured,
but this isn't strictly required, as Windows will not try to locate the
sysprep floppy in subsequent boots. The only minor inconvenient is that
the users of the VMs will see the floopy and its content attached.
Yes, this is exactly the workaround I'm currently using, and I have to
hide floppy via AD group policy (sysprep.inf contains administrator
password).
2. Use the builtin sysprep files (they are in
/usr/share/ovirt-engine/conf/sysprep):
vm = vms.get(name="myvm")
initialization = params.Initialization()
vm.set_initialization(initialization)
vm.update()
vm.start(params.Action())
This has the advantage that the sysprep floppy will be attached to the
VM only the first time it is booted. In subsequent boots it won't be
attached.
Great hint, I'll take a look into those syspreps to see if they fit for
my setup.
In 3.5 you will also be able to use sysprep support with your custom file:
vm = vms.get(name="myvm")
initialization = params.Initialization(
custom_script="The text of your sysprep file"
)
vm.set_initialization(initialization)
vm.update()
vm.start(params.Action())
Good new, eventually I'll wait for RHEV 3.5
Note that currently (in 3.4 and in 3.5) there is an issue with the name
of the file generated by the built-in sysprep support: it will always be
named "sysprep.inf", regardless of the operating system assigned to the
VM. If you want to use recent versions of Windows it has to be named
"Unattend.xml", so you will need to change the Windows template before
sealing it, adding the following registry entry:
HKEY-LOCAL-MACHINE -> SYSTEM -> Setup -> UnattendFile = sysprep.inf
There is a bug open to avoid this:
https://bugzilla.redhat.com/1145999
Note also that the builtin sysprep support will only trigger if the VM
has been assigned a Windows operating system.
Yes, I knew. Do you know if is there a plan to change this behaviour
(e.g. generate filename according to guest O.S. standard)?
Many thanks,

The problem is that using non persistent payloads isn't currently
supported, so basically your "payloads" element is silently ignored. You
have currently two alternatives:
1. Use persistent payloads:
vm = vms.get(name="myvm")
vm.set_payloads(paylaods)
vm.update()
vm.start(params.Action())
You may also want to remove the payloads once the machine is configured,
but this isn't strictly required, as Windows will not try to locate the
sysprep floppy in subsequent boots. The only minor inconvenient is that
the users of the VMs will see the floopy and its content attached.
2. Use the builtin sysprep files (they are in
/usr/share/ovirt-engine/conf/sysprep):
vm = vms.get(name="myvm")
initialization = params.Initialization()
vm.set_initialization(initialization)
vm.update()
vm.start(params.Action())
This has the advantage that the sysprep floppy will be attached to the
VM only the first time it is booted. In subsequent boots it won't be
attached.
In 3.5 you will also be able to use sysprep support with your custom file:
vm = vms.get(name="myvm")
initialization = params.Initialization(
custom_script="The text of your sysprep file"
)
vm.set_initialization(initialization)
vm.update()
vm.start(params.Action())
Note that currently (in 3.4 and in 3.5) there is an issue with the name
of the file generated by the built-in sysprep support: it will always be
named "sysprep.inf", regardless of the operating system assigned to the
VM. If you want to use recent versions of Windows it has to be named
"Unattend.xml", so you will need to change the Windows template before
sealing it, adding the following registry entry:
HKEY-LOCAL-MACHINE -> SYSTEM -> Setup -> UnattendFile = sysprep.inf
There is a bug open to avoid this:
https://bugzilla.redhat.com/1145999
Note also that the builtin sysprep support will only trigger if the VM
has been assigned a Windows operating system.

[ovirt-users] python floppy in RunOnce mode
Hi,
I'm trying to boot a vm with non persistent floppy using python ovirt
sdk (the "RunOnce" way in administrator portal), but guest OS can't see
floppy drive. The ultimate goal is to deploy floppy with sysprep
unattend.xml file for windows 7 pools of vm.
Here is a snippet of code I use:
-
myvm = api.vms.get(name="vmname")
content="This is file content!"
f=params.File(name="foobar.txt",content=content)
fs=params.Files()
fs.add_file(f)
payload=params.Payload()
payload.set_type("floppy")
payload.set_files(fs)
payloads=params.Payloads()
payloads.add_payload(payload)
thevm=params.VM()
thevm.set_payloads(payloads)
action=params.Action(vm=thevm)
myvm.start(action=action)
xml = ParseHelper.toXml(action)
print xml
-
As you can see, for debugging purpose, I print my xml action, and I get:
-
foobar.txt
This is file content
-
in the admin portal I can see my vm in "RunOnce" state, but no floppy is
present...
In fact in the vm process command line
(ps -ef | grep qemu-kvm | grep vmname) I can't see -drive option
referring to floppy (I only see 2 "-drive" options, referring to vm
system disk and to a correctly mounted cdrom ISO)
What I'm doing wrong?
(The engine is RHEV-M version 3.4.1-0.31.el6ev)
Thanks in advance,
Giulio
