I installed ovirt on a machine that was already hosting KVM virtual machine=
s. I am now trying to migrate those VMs over to RHEV format=2C but I am rec=
eiving SASL authentication errors using virt-v2v.
I am not being prompted for credentials upon running the command:
virt-v2v Windows7.xml -o rhev -os host.domain.net:/home/images --network ov=
irtmgmt Windows7=0A=
The error is:

This has been driving me crazy all night. Does anyone know anything about t=

Hi,
I made some tests as I could need something similar in the near future...
This is what I found from my tests
You need authentication for libvirt after oVirt configuration took
place on your server.
So you can create a user for libvirt and try then the commands with
that user credentials.
It worked for me in the past to try to start a VM directly from
libvirt on an all-in-one system to debug problems.
So:
# saslpasswd2 -a libvirt virshuser
Password: <define a password>
probably the disks of your pre-existing vm should be put with these permissions
chown vdsm.kvm /var/lib/libvirt/images/testvm.img
chmod 0660 /var/lib/libvirt/images/testvm.img
try to see eventually if you can start your vm now:
# virsh start testvm
I have an AIO install with fedora 19 and oVirt 3.3.1 stable
Actually I have not a kvm infra but I created one fake in the sense
that I created a storage pool and a disk inside it
[root@tekkaman ~]# cat pool.xml
<pool type="dir">
<name>virtimages</name>
<target>
<path>/var/lib/libvirt/images</path>
</target>
</pool>
virsh pool-create pool.xml
I copied an image (fedora19) inside it and refreshed the pool
virsh pool-refresh virtimages
virsh vol-list --pool virtimages
[root@tekkaman ~]# virsh vol-list --pool virtimages
Please enter your authentication name: virshuser
Please enter your password:
Name Path
-----------------------------------------
testvm.img /var/lib/libvirt/images/testvm.img
I define a basic VM with test.img as a disk
virsh define test.xml
[root@tekkaman ~]# virsh list --all
Please enter your authentication name: virshuser
Please enter your password:
Id Name State
----------------------------------------------------
2 f19 running
- test shut off
NOTE: the f19 above is a fedora 19 vm running inside oVirt itself,
while test is the VM just created with virsh commands
Now, even if I don't now if it is still required in f19
export LIBGUESTFS_ATTACH_METHOD=appliance
and also if you want to debug virt-v2v (used to debug, see below my
workaround due to a permission error otherwise...)
export LIBGUESTFS_DEBUG=1
Now you can run
virt-v2v -ic qemu://virshuser@tekkaman.localdomain.local/system -o
rhev -os tekkaman.localdomain.local:/data/export_domain --network
ovirtmgmt test
tekkaman.localdomain.local is my server from which I run the comamnds
that is both oVirt AIO (so engine+hypervisor) and now is also source
for the KVM vm I want to put into oVirt export domain
NOTE: the command will not ask a password.. donna if it is a bug or not...
During virt-v2v, the export domain is mounted locally under
/tmp/<random_path> (eg. /tmp/f6X_Ea809r/)
For some reason the permissions are not ok for virt-v2v and give an
error of permission denied attempting to open the disk.
You cannot directly change the permissions under /tmp, you have to do
on the local path of the export domain.
In my case it is on the very same server under /data/export_domain path
SO I did these tricks below to the temporarily created dir to have
virt-v2v able to complete.
And now I see the imported VM under export domain 'VM import" sub-tab
in webadmin page

You have to do these steps during the initial phase when there is the
copy of the image and you have the ==== progress bars..
