Re: [libvirt] VolumeCreateXML "XML" description for ESX



Great ! it did pass the error of directory/file thank you for the support now i have another problem of creating the VMDK image with this XML
<volume><name>test_vm/test_vm.vmdk</name><allocation>0</allocation><capacity unit='G'>2</capacity><target><format type='vmdk'/></target></volume>

and error

libvir: ESX error : internal error Could not create volume
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python2.7/site-packages/libvirt.py", line 1116, in createXML
    if ret is None:raise libvirtError('virStorageVolCreateXML() failed', pool=self)
libvirt.libvirtError: internal error Could not create volume

may be it is an ESX server side problem or i am still missing or messing up something ?

This XML snippet should work

<volume>
 <name>test_vm/test_vm.vmdk</name>
 <allocation>0</allocation>
 <capacity unit='G'>2</capacity>
</volume>

The error message says that the volume name doesn't have the expected
format <directory>/<file>. The <> might be misleading here, they don't
refer to XML elements.

I can probably relax this and allow files in the datastore root. The
problem with a .vmdk file in the datastore root is that ESX doesn't
allow a virtual machine to be registered (or defined in libvirt terms)
in the datastore root. The typical layout is to have a subdirectory
per virtual machine.
