tested it out, run once flow doesn't pass any custom property to the hypervisor. simple workaround: edit vm -> show advanced options (button) -> custom properties (section) these properties stick. anyway as Sven said you can report a bug (good for tracking).

Hi,
when using CustomProperties they are not being passed when starting VM with Run. How to reproduce:
vim /usr/libexec/vdsm/hooks/before_vm_start/99_remove_cpu
#!/usr/bin/python
import os
import sys
import hooking
if hooking.tobool(os.environ.get('remove_cpu')):
sys.stderr.write('TRUE')
else:
sys.stderr.write('FALSE')
sys.exit(0)
chmod 755 /usr/libexec/vdsm/hooks/before_vm_start/99_remove_cpu
engine-config -s UserDefinedVMProperties='remove_cpu=^(true|false)$' --cver=3.3
service ovirt-engine restart
Setup Virtual Machine with custom property set. When starting VM via Run, vdsm.log shows ‘TRUE’:
Thread-1830::DEBUG::2014-01-30 08:58:35,767::utils::489::root::(execCmd) '/usr/libexec/vdsm/hooks/before_vm_start/99_remove_cpu' (cwd None)
Thread-1830::DEBUG::2014-01-30 08:58:35,794::utils::509::root::(execCmd) SUCCESS: <err> = 'TRUE'; <rc> = 0
When calling the same via Run Once (the dialog even shows that the custom property is set: http://imgur.com/wVSe75L ), the vdsm.log shows ‘FALSE’:
Thread-1589::DEBUG::2014-01-30 08:52:24,219::utils::489::root::(execCmd) '/usr/libexec/vdsm/hooks/before_vm_start/99_remove_cpu' (cwd None)
Thread-1589::DEBUG::2014-01-30 08:52:24,246::utils::509::root::(execCmd) SUCCESS: <err> = 'FALSE'; <rc> = 0
Best Regards,
Christopher
