Description of problem:

Attempting to add an LVM VolGroup is not clear.  It appears like the dialog is not allowing me to enter a the volume group.  Perhaps tooltips or documentation might be in order.

Version-Release number of selected component (if applicable):

libvirt-0.4.5-2.fc10.i386
virt-manager-0.6.0-1.fc10.i386
qemu-0.9.1-10.fc10.i386

How reproducible:
100%

Steps to Reproduce:
1. start virt-manager
2. Select 'Details' for QEMU localhost
3. Select 'Storage Pools' tab
4. Select 'Add'
5. Select type=logical, name=VolGroup00, select Next
6. Select Next

Actual results:

Clicking next yields ...

Expected results:
 * it doesn't appear possible to enter a LVM Volume Group name for use with the storage pool

This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.

Comment 2 Daniel Berrangé 2009-01-22 13:15:42 UTC
Re-assigning to virt-manager for now, because from my testing, the libvirt side of things is working OK.

Comment 3 Cole Robinson 2009-04-06 18:06:13 UTC
If I understand correctly, the root of this issue is that the storage pool 'name' for an LVM pool is used as the source VG name, if no source name is specified (if creating a pool from an existing VG). This is confusing, since for all other storage pool types, 'name' is strictly metadata.

We should really be using the logical pool discovery functionality to provide a list of volume groups to the user: we can use this info to specify the 'source' device name. Granted, it would be nice if libvirt did this behind the scenes if no source name is specified, but we need to implement this functionality in virt-manager regardless.

Comment 4 Cole Robinson 2009-09-14 15:55:56 UTC
This likely won't be fixed for F10, moving to F11.

Comment 5 Cole Robinson 2009-10-21 14:17:37 UTC
We now support pool enumeration upstream:

http://hg.fedorahosted.org/hg/virt-manager/rev/d46b95ddbbcf

This requires changes across virtinst and virt-manager, so I don't think this will be backported to F11. Moving to rawhide/F12

Comment 6 Cole Robinson 2009-12-03 23:52:49 UTC
This should be fixed in virt-manager-0.8.1-1.fc13 which will be in the next rawhide compose.
