libvir: error : invalid argument: virStorageVolLookupByPath #2

Hi.

I have all my KVM guests installed to LVM disks. Webvirtmgr can see the pool, and list all the guests. But when I'm trying to access them from the menu on the left, I get error 500. Django says: libvir: error : invalid argument: virStorageVolLookupByPath

And the traceback:

Traceback (most recent call last):

File "/usr/lib/python2.7/dist-packages/django/core/handlers/base.py", line 111, in get_response response = callback(request, _callback_args, *_callback_kwargs)

File "/var/www/webvirtmgr/polls/views.py", line 1145, in vm hdd_image = get_dom_hdd(storages)

File "/var/www/webvirtmgr/polls/views.py", line 1095, in get_dom_hdd img = conn.storageVolLookupByPath(hdd)

File "/usr/lib/python2.7/dist-packages/libvirt.py", line 3150, in storageVolLookupByPath if ret is None:raise libvirtError('virStorageVolLookupByPath() failed', conn=self)

libvirtError: invalid argument: virStorageVolLookupByPath

This is an issue when a pool is not defined but in my case it is. The /dev/fridge is the volume group where my guests are installed, e.g: --- Logical volume --- LV Path /dev/fridge/mail01 LV Name mail01 VG Name fridge LV UUID ihBj5b-03zN-FcZd-I30o-lmYe-61BS-J0qzYM LV Write Access read/write LV Creation host, time , LV Status available

open 1

LV Size 10.00 GiB Current LE 2560 Segments 1 Allocation inherit Read ahead sectors auto

Virsh shows the pool as well. virsh # pool-info fridge Name: fridge UUID: a1823e4e-d3ce-4ed5-02d0-847f4a601e98 State: running Persistent: yes Autostart: yes Capacity: 5.46 TiB Allocation: 5.22 TiB Available: 239.04 GiB

I can also see the pool in the web interface.

Any idea why this doesn't work?

You need your VG "fridge" add to storage pool.

ezPappi commented 11 years ago

It's already in the pool. See the output of virsh pool-info Additionally:

cat /etc/libvirt/storage/fridge.xml shows: http://pastie.org/private/ntdb6lyuaxd3hexb23q

VM create in WebVirtMgr or have already been created?

ezPappi commented 11 years ago

They have already been there. I created one Logical volume with webvirtmgr but it put an .img in the name of the volume (something I don' want) so I did not use it for that.

ezPappi commented 11 years ago

Looking at get_img_path function in views.py it seems to want to find .img for volumes.

retspen commented 11 years ago

Yes this funciton find only .img. Fix this bug in new release.

Any idea when this will be?
