Hi this is a Permission issue. Usually the problem is that KVM run
as root and take over permission on images. You can prevent this by
the proper settings of KVM.<br>
<br>
qemu.conf<br>
<br>
# The user ID for QEMU processes run by the system instance.<br>
user = "oneuser"<br>
<br>
# The group ID for QEMU processes run by the system instance.<br>
group = "onegroup"<br>
<br>
# Whether libvirt should dynamically change file ownership<br>
# to match the configured user/group above. Defaults to 1.<br>
# Set to 0 to disable file ownership changes.<br>
dynamic_ownership = 0<br>
<br>
And if you do that you need to add oneuser to the kvm group to allow
acces to /dev/kvm... I hope it solves ur problem.<br>

<td style="font: inherit;" valign="top">Hi,<br>
I found a small bug in OpenNebula v3.2.1.<br>
<br>
When I try to delete a VM with a persistent image, the
image switch in the ERROR state and the following trace
appear in the log :<br>

It seems that the delete action is doing the following
steps :<br>
- Move image to the repo<br>
- Delete image on the host<br>
- Destroy the vm<br>
<br>
But the image is not transferred and cause the error. I
thinks steps should be :<br>
- Destroy the vm<br>
- Copy back the image from the host<br>
- Move image to the repo<br>
- Delete image on the host<br>
<br>
I've tried to fix it, but I got lost somewhere between
C++ and Ruby...<br>
<br>
Subsidiary question, why is the core written in C++ and
not in Ruby ?<br>
<br>
Thanks,<br>
