Last modified: 2008-01-22 10:52:31 EST
Description of problem:
At the end of the virtual machine creation process I get an error message box
and that prevents me from finishing the creation of a virtual machine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run virt-manager (unprivileged)
2. connect to the localhost machine
3. right click on the localhost machine and select "New"
4. click forward
5. name the machine "fedora7test"
6. click forward (accept fully virtualized i686 arch with kernel/hardware
7. select an iso for booting
8. select OS type as "Linux"
9. select OS Variant as "Fedora 7"
10. click "Forward"
11. set hdd image path to "/home/plouj/vm/fedora7test.img"
12. click "Forward" twice (accepting 500MB virtual machine RAM and 1 VCPU)
13. click "Finish"
14. wait for virtual disk creation to finish
Message box with the following pops up:
Unable to complete install '<type 'exceptions.AttributeError'> 'NoneType' object
has no attribute 'setup'
Traceback (most recent call last):

Virtual machine is successfully created without any errors.
I got a similar result in F8. This was trying to create a virtual machine using
qemu and kvm running Windows XP. I tried it running Virtual Machine Manager as
unprevileged when starting it. Trying again, entering root password on VM
Manager startup, allowed successful creation of the virtual machine.
In addition, running the root password provided an extra config screen when
creating the VM. This was to do with with the type of network (virtualised etc)
to be connected to the VM.
I just applied a fix for this upstream.
I will close this bug when a new release is cut and pushed to F8. Thanks for bug
virt-manager-0.5.3-1.fc8 has been pushed to the Fedora 8 testing repository. If problems still persist, please make note of it in this bug report.
If you want to test the update, you can install it with
su -c 'yum --enablerepo=updates-testing update virt-manager'
While the problem as described has gone away, the patch only fixes half of the
problem. The other half of the problem is that no NIC's get defined for the
guests. This is due to the fact that vmmCreate._net gets populated in
vmmCreate.validate(PAGE_NETWORK), but as that page is never shown to
unprivileged users, the network never gets configured.
Hmm, I'm not too familiar with how user mode networking is done: I was under the
impression the page was deliberately skipped in the install because a regular
user couldn't use any of the presented options. Let's use this bug to track the
install failure issue, and I'll open a bug for the lack-of-networking issue.
bz #378991 : add usermode networking support to virt-manager
gah... my brain failed. bug is bz 428852 :
virt-manager-0.5.3-1.fc8 has been pushed to the Fedora 8 stable repository. If problems still persist, please make note of it in this bug report.
