[virt-tools-list] virtinst iso error 'Size must be specified for non existent volume path'

[Dale Bewley]

All my other guests were created via network boot, when attempting to create a windows guest using a local iso image I'm getting the following error:

[Mon, 10 May 2010 15:17:03 virt-manager 15053] DEBUG (error:76) Uncaught Error: Unable to complete install: 'Size must be specified for non existent volume path '/var/lib/libvirt/images/Windows_Server_2003_R2_Enterprise.iso'' : Unable to complete install '<type 'exceptions.ValueError'> Size must be specified for non existent volume path '/var/lib/libvirt/images/Windows_Server_2003_R2_Enterprise.iso'

The volume path does exist. However, while the error displays the correct number of '/' delimiters the vol-list contains an extra '/'.

I'm running:

python-virtinst-0.400.3-12.fc11.noarch

libvirt-0.6.2-19.fc11.x86_64
virt-manager-0.7.0-8.fc11.x86_64


I found the following links so far:

https://bugzilla.redhat.com/show_bug.cgi?id=465551
http://www.redhat.com/archives/virt-tools-list/2009-November/msg00107.html


I tried removing the trailing '/' on the path above with 'virsh pool-edit' but the '/' was automatically re-added.

Is there a fix for this that never made it back into F11?
