[et-mgmt-tools] user questions - iscsi and nfs storage

[mike.hinz at yr20.com]

Hi, I'm a user and couldn't find a user oriented list for virt-manager so I'd thought I'd ask here. I have a few questions regarding using network storage with virt-manager.  I'm using the Fedora 11 beta with libvirt and virt-manager updated to the latest from rawhide. Â Virt-manager is version 0.7.0-4 built on 14 April. Further background is that I have an openfiler in my office with both iscsi and nfs enabled.  I can access both properly from my physical host.

My first question is in regards to iscsi.   It appears that I can enabled an iscsi pool, but I can't seem to create any volumes in it via virt-manager. Is this the way it as or am I doing something wrong?  If this is the way it is, is there any plan to enabled this functionality in virt-manager?

My 2nd question is in regards to nfs.  It appears that I can create a pool, but get errors when trying to create volumes for VMs.  I get the following in the popup:

Error creating vol: Couldn't create storage volume 'test1.img': 'cannot create path '/mnt/nfspoint/test1.img': Invalid argument'

Looking at the details gives:

Traceback (most recent call last):
 File "/usr/share/virt-manager/virtManager/createvol.py", line 187, in _async_vol_create
  self.vol.install(meter=meter)
 File "/usr/lib/python2.6/site-packages/virtinst/Storage.py", line 905, in install
(self.name, str(e)))
RuntimeError: Couldn't create storage volume 'test1.img': 'cannot create path '/mnt/nfspoint/test1.img': Invalid argument'

However, I can open a console and navigate to /mnt/nfspoint and I can see the images files created there, although each has zero size. They never appear in nfstest storage pool that I created though.

Interestingly, I can delete the nfs volume and attempt to reinitialize it and when I do, i see the two volumes that I attempted to create earlier, even though they don't exist!  I've confirmed that in fact that they don't exist via an examination of /mnt/nfspoint. 

So, can someone give me some advise here on how this is supposed to work and what I'm doing wrong?

Thanks in advance for any help that you can give me!
