<div>Hi,<br>
<br>
</div>
<div>Just to make clear what you want to achieve:<br>
</div>
<div>- DC1 - local storage - host1 - VMs<br>
- DC2 - local storage - host2 <br>
<br>
</div>
<div>You want to move the VMs from DC1 to DC2.<br>
</div>
</div>

<br>
Yes, thanks, this is exactly what I want to accomplish.<br>
BTW, are export domains from different data centers visible to each
other?<br>
<br>
If not, wouldn't be simpler to export VM#1 in DC #1 to Export domain
#1, copy over ssh to DC #2 Export domain, and finally import it into
DC #2.<br>
<br>
PS. I can't test right now myself, sitting home on sick leave..<br>

<div>What you can do:<br>
</div>
<div>- Add a shared storage domain to the DC#1 <br>
</div>
<div>- Move VM disk from local SD to shared storage domain<br>
</div>
<div>- Put shared storage domain to maintenance<br>
</div>
<div>- Detach shared storage from DC1<br>
- Attach shared storage to DC2<br>
</div>
<div>- Activate shared storage <br>
</div>
<div>- You should be able to register the VM from the shared
storage into the DC2<br>
</div>
<div>- If you want/need move disks from shared storage to local
storage in DC2<br>
<br>
</div>
<div>Please test this flow with a dummy VM before doing on
important VMs.<br>

</div>
<div>Thanks for clarification. I’m using 4.2.</div>
<div>Anyway, I have to define another data center with
shared storage domain (since data center with local
storage domain can have only 1 host), and the do what
you have described.</div>
<div><br>
</div>
<div>Is it possible to copy VM disks from 1 data center #1
local storage domain to another data center #2 NFS
storage domain, or need to use export storage domain ?

<div>Hi,<br>
</div>
Which version are you using?<br>
<br>
</div>
in 4.1 , the support of adding
shared storage to local DC was added
[1].<br>
</div>
You can copy/move disks to the shared
storage domain, then detach the SD and
attach to another DC.<br>
<br>
</div>
In any case, you wont be able to live
migrate VMs from the local DC, it is not
supported.<br>
<br>
</div>
Regards,<br>

<div><br>
</div>
<div>I have oVirt setup, separate PC
host engine + 2 nodes (#10 + #11)
with local storage domains (internal
RAIDs).</div>
<div>1st node #10 is currently active
and can’t be turned off.</div>
<div><br>
</div>
<div>Since oVirt doesn’t support more
then 1 host in data center with
local storage domain as described
here:</div>
<div><a

moz-do-not-send="true">http://lists.ovirt.org/piperma<wbr>il/users/2018-January/086118.<wbr>html</a><br>
defined another data center with 1
node #11.</div>
<div><br>
</div>
<div>Problem: </div>
<div>1) can’t copy or move VM disks
from node #10 (even of inactive VMs)
to node #11, this node is NOT being
shown as possible destination.</div>
<div>2) can’t migrate active VMs to
node #11.</div>
<div>3) Added NFS shares to data
center #1 -> node #10, but can’t
change data center #1 -> storage
type to Shared, because this
operation requires detachment of
local storage domains, which is not
possible, several VMs are active and
can’t be stopped.</div>
<div><br>
</div>
<div>VM disks placed on local storage
domains because of performance
limitations of our 1Gbit network. </div>
<div>2 VMs running our
accounting/inventory control system,
and are critical to NFS storage
performance limits.</div>
<div><br>
</div>
<div>How to solve this problem ?</div>
<div>Thanks in advance.</div>
