Re: [ovirt-users] Can't move/copy VM disks between Data Centers

2018-03-05 Thread Fred Rolland
Using Export domain should work also, but I would go the way I described
earlier.

Yes, thanks, this is exactly what I want to accomplish.
BTW, are export domains from different data centers visible to each other?

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.

PS. I can't test right now myself, sitting home on sick leave..

Re: [ovirt-users] Can't move/copy VM disks between Data Centers

2018-02-27 Thread Fred Rolland
Hi,

Just to make clear what you want to achieve:
- DC1 - local storage - host1 - VMs
- DC2 - local storage - host2

You want to move the VMs from DC1 to DC2.

What you can do:
- Add a shared storage domain to the DC#1
- Move VM disk from local SD to shared storage domain
- Put shared storage domain to maintenance
- Detach shared storage from DC1
- Attach shared storage to DC2
- Activate shared storage
- You should be able to register the VM from the shared storage into the DC2
- If you want/need move disks from shared storage to local storage in DC2

Please test this flow with a dummy VM before doing on important VMs.

Regards,

Freddy

Re: [ovirt-users] Can't move/copy VM disks between Data Centers

2018-02-26 Thread Andrei Verovski
Hi,

Thanks for clarification. I’m using 4.2.
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.

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 
?

Re: [ovirt-users] Can't move/copy VM disks between Data Centers

2018-02-26 Thread Fred Rolland
Hi,
Which version are you using?

in 4.1 , the support of adding shared storage to local DC was added [1].
You can copy/move disks to the shared storage domain, then detach the SD
and attach to another DC.

In any case, you wont be able to live migrate VMs from the local DC, it is
not supported.

Regards,
Fred
