Hi,
Reading the docs all day long helped me to setup a nice Data center in
iSCSI mode, connected to a big LUN in a san.
Many many points are working, mostly thanks to you, people of this list.
Apart from this oVirt setup (1 manager, 3 nodes, 1 san), I have a
completely separated ubuntu hypervisor running a standalone local KVM
with a local storage.
I have not a clear view of how I will manage to import these VM into oVirt.
Of course, I've read about ovirt-v2v (and its huge amount of
dependencies...), but I'm not sure this is the way I have to follow?
As far as I've understood, v2v seems to be dedicated to connection
between oVirt datacenters, or vmware or Xen plateforms, but I see
nothing about the connection to a distant standalone KVM hypervisor.
One more thing that is unclear to me, and seems related, is the notion
of export / import domain. I read that this principle could allow me to
export (then to backup) my VMs. This could help me to import some VMs.
But I read that this export domain has to be the same type of my
datacenter (iscsi), so this is not helping me with my standalone kvm
hypervisor.
I'd be glad to get some light on these points.

Hi Nicolas,
you can attach NFS export domain to iSCSI data-center. There is no need
to have same export domain type as your data-center has. I hope it will
help you to solve your problem.

Hi,
The following command migrates a KVM vm named "test-rhel6" to your
export domain "ovirt-engine:/data/nfs/export" with qcow2, thin
provisioned disk and ovirtmgmt-network from KVM host "kvm-host":
# virt-v2v -i libvirt -ic qemu+ssh://root@kvm-host/system -o rhev -os
ovirt-engine:/data/nfs/export -of qcow2 -oa sparse -n ovirtmgmt
test-rhel6
See "virt-v2v --help" for details...
You can also create a profile in /etc/virt-v2v.conf to avoid command
line arguments for virt-v2v...
For migration you need an export domain which must be NFS (not iSCSI).
So the migration steps are:
1. create export domain
2. activate export domain on datacenter
3. install virt-v2v on ovirt engine host
4. migrate host to export domain
5. import vm from export domain

For migration you need an export domain which must be NFS (not iSCSI).
So the migration steps are:
1. create export domain
2. activate export domain on datacenter
3. install virt-v2v on ovirt engine host
4. migrate host to export domain
5. import vm from export domain
Thank you to Alex, Jakub (you were right, an NFS export domain is OK
with an iSCSI data center), and René.
- On a separate server, I created a NFS shared space.
- On oVirt web gui, I created a new export domain, plugged on the NFS space.
- I activated it, linked it to my iSCSI data center.
- On the oVirt manager, I installed virt-v2v and its numerous
dependencies. Seemless.
- Converting a domain using René's advices went all right (thank you).
- Importing into oVirt was also OK.
All those actions were related to linux VMs.
Now, the problem comes with migrating windows vmachines.
I read here at 3.3.1.2 :
https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Virtual...
that I had to install three things, more or less optional :
- virtio-win (this one seems mandatory, as I'm getting the error :
virt-v2v: blah blah blah missing :
/usr/share/virtio-win/drivers/i386/WinXP or whatever windows OS - I
tried many)
- libguestfs-winsupport (I don't know whether it is mandatory, as I'm
hitting the bug above.It seems important as it seems related to the file
system, so quite useful)
- Guest Tools ISO (this one seems to be similar to VmWare tools, if I
understood it well), so I don't know if it's an improvement only,
neither where to find it for oVirt and Fedora.

Hu ho, I think I hit this bug :
http://thr3ads.net/libguestfs/2011/11/1623975-Virtio-win-RPM
and
http://thr3ads.net/libguestfs/2011/11/1624040-Windows-P2V-migration-tempo...
I have a RHN account, so I was able to download the missing virtio-win
rpm and install it on F17 (seemless).
Import is now working for windows guest, though some more errors are to
be treated manually (eth virtio errors), but harmless.

Hi Itamar, Hi people,
I don't know if your proposal was directed to me, but I just *found*
this thread, but never wrote anything into it, so you'd better ask
concerned people about their writings.

Hi, How can I install virtio-win and libguestfs-winsupport , it looks like a
RHEV package not a ovirt package.
