Suppose your existing KVM installation server has connectivity with engine (eg 10.4.4.59) and you have configured an export domain on engine with sufficient available space, you can connect on your KVM server and run (for example on CentOS 6.3): # virt-v2v -o rhev -osd 10.4.4.59:/EXPORT --network ovirtmgmt c56cr c56cr_001: 100% [===]D 0h02m17s virt-v2v: c56cr configured with virtio drivers. this will port your curren tVM network into the ovirtmgmt one on oVirt. If you have more that one you can specify them in command line. see man virt-v2v for options explanation When export completes successfully, you can then go into web admin portal, select the export domain and the VM imported will show up. And you can import it, also customizing some parameter. HIH, Gianluca ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [Users] Thin provisioning extending while Make template still a bug?
Hi Adrian, Sorry for the late respond. Please see inline comments, and feel free if there are any more questions, or other issues which you want us to address to. p.s. Since some of the responds were in different threads, I gathered all of them to this email. 3) About the attached logs the virtual machine made from template was finally made at: 2012/12/22 17:21 Logs are from 16:17 to 17:21 aproximately and I might reuse them to ask why it takes so long to make the virtual machine while checking the storage image at /home/storage (its size) it would seem that the copy has finished. I think that the Make vm from template task started about 30 minutes or 40 minutes before it being finished. Well, that's the average time it takes for me. Since you are creating a server the default behaviour is to clone your disks, which means engine calls copyImage to the SPM. From what I saw in the logs your template have two disks, which one of them is 1920 GB, this is why it took 30 minutes to copy it. If you want your copy to be faster, you can change the default in the resource allocation tab to use thin instead of clone when you add a new server. although, take in notice that when you will use thin provisioning, the server will be based on the template and you will not be able to remove the template until the VM will be removed.

Re: [Users] Fail to connect to an iSCSI Eq. LUN
Too bad : I did not change anything, and time passing by, it all came to
work...
Damn, this is the worst sysadmin situation : this is working, and you
don't know why !
Seriously : it indeed appears that the choice of shared access is the
good one (until someone proves it wrong).
More seriously : I shut down the second node, and made the conection
with only the first node alive.
In that case, no possible conflict.

Hi,
As a beginner, I'm reading again and again, but I'm not sure of the best
way to do :
Through the oVirt web manager, I'm trying to create an iSCSI storage
domain.
On my Equalogic SAN, I've created a volume with no restriction access
(for the time being).
I have two hypervisors on which I'm quite sure my network config is good
enough for now (two nics bonded for the management, and 2 nics bonded
for the iscsi). Everything is pinging ok. Networking is not an issue.
In the ovirt web manager, I try to create the very first storage domain,
of iscsi type of course.
I choose one of the node, then the iscsi discovery + login is working fine.
I can see my Equalogic volume, I'm checking it, and saving with the OK
button, and I get the following error :
Error while executing action New SAN Storage Domain: Physical device
initialization failed. Check that the device is empty. Please remove
all files and partitions from the device.
Not very interesting, but the node log file is more instructive :

I guess the interesting part is :
Can't open /dev/mapper/364ed2ad5297bb022fd0ee5ba36ad91a0 exclusively.
Mounted filesystem?
On any node, this partition is not mounted.
But I have set up the access to this volume as shared on the Equalogic
SAN, not knowing whether I should do so? I see both nodes connected on
the same volume.
I tried to remove this permit, but it didn't help.
I also found Redhat answering such a question :
There are two ways to clear this error:
- Remove VG from the Storage LUN using vgremove command. Run this
command from one of the hypervisors.
- Clear the first 4K from the disk . Execute the following from
one of the hypervisors:
# dd if=/dev/zero of=/dev/mapper/diskname bs=4k count=1
I did try that, but with no luck.
Now, two things :
- Do I have to keep the access to this volume shared/allowed to all the
hypervisors dedicated to this volume?
- What is the problem with the pvcreate command?

Re: [Users] Storage domain weirdness (or design)
Hi Alex, The storage domains are part of the Data Center, and should not be related to clusters. Clusters are used for migrating VMs, which are the qemu processes, between hosts. Disks are created on the storage domains regardless to clusters. The host which write the data in the storage domain to create the disk is the SPM. You should have only one SPM in each Data Center (You can spot which host is your SPM by looking at the SPM column in the hosts tab) When you create a disk you should be able to choose the storage domain which you want the disk to be created on.
