Hello,
Since updating to libvirt 3.0 I am no longer able to create a virtual
machine that is backed by LVM storage on my two Arch machines.
This is the error in virt-manager:
Unable to complete install: 'An error occurred, but the cause is unknown'
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 88, in cb_wrapper

File "/usr/share/virt-manager/virtManager/create.py", line 2288, in

if ret is None:raise libvirtError('virDomainCreateXML() failed', conn=self)
libvirtError: An error occurred, but the cause is unknown
I originally encountered the problem when running my Ansible modules
for libvirt in https://github.com/ansible-provisioning/ansible-provisioning
, so the issue is not virt-manager specific.
Steps to reproduce in virt-manager (1.4.0-3):
- create a new VM
- choose import existing disk image
- create a new logical volume when browsing to find the existing image
path or select a lv that was manually created before.
- click forward
- click forward
- click finish
When using qcow2 storage, both virt-manager and my modules work fine.
This was also working on previous versions of libvirt. I do not see
any changes in compilation flags in the Arch packages.
Is there anything I can do to help diagnose this issue?
Greetings,
Jeroen
