Re: [ovirt-users] when creating VMs, I don't want hosted_storage to be an option

[Martin Sivak]

Hi,

we got much closer to officially remove the specialty status of both
the domain and the VM in 4.2 with features like Node 0 deployment
(default since 4.2.1) and direct libvirtxml support in engine and HE
(4.2.2 iirc).

There are couple of outstanding issues:

- HE needs to know how to connect all storage domains necessary for HE
VM disks (not 100% related, but close)
- (live) storage migration is not supported yet - HE nodes need to
learn about the new connection details
- changes to gluster topology are not supported yet - same reason as above
- we have a bug with regards to block devices - will be fixed by
https://gerrit.ovirt.org/#/c/87325/
- fencing and SPM role need to be tested a bit more to make sure we
have no surprises there
- old deployments might not have some data in the engine DB
(https://bugzilla.redhat.com/show_bug.cgi?id=1373930)

We will not be adding any additional limits as all seems to work in
the usual cases and we work on removing the remaining restrictions. I
am not 100% certain when it will be finished exactly, but you can use
it now if you are careful (basically do not use custom mount options
and do not add disks to the HE VM that would come from a different
SD!!).

We have two tracking bugs for the related work:
https://bugzilla.redhat.com/show_bug.cgi?id=1455169 and
https://bugzilla.redhat.com/show_bug.cgi?id=1393902 - most of what was
needed was fixed already.

Best regards

Martin Sivak

Hello Martin (and list),
any update on this item to remove specialty of hosted_engine storage?
Any bugzilla RFE or pointer? I think it didn't catch 4.2, correct?

So far so good.  I renamed it, but it was still listed first in the list when 
creating an image for a VM.  After closing out my browser and reconnecting, 
it’s now behaving as I’d expect - in alphabetical order.

[Martin Sivak]

I do not see any reference to the name in the engine source code.
Hosted engine agent uses UUID to identify it. So I think it should be
fine.

Can it be safely renamed?  It looks like the GUI will let me but I don’t feel 
confident that it won’t create other issues.

Re: [ovirt-users] when creating VMs, I don't want hosted_storage to be an option

[Martin Sivak]

Hi,

Chris is right. We want to remove the specialty status from that
storage domain. It is one of the highest priority items for hosted
engine right now.

There is currently no way to hide it I am afraid.

Best regards

[Fred Rolland]

As a workaround, I think that the list of storage domains in the new disk
window is sorted alphabetically.
You can try to edit the name of the storage domain to be on the bottom of
the list and not first.

This would be a nice thing to have.

AIUI, however, the oVirt folks are working towards not needing a
dedicated storage domain for the hosted engine, which may alleviate this
particular gripe. That being said, it would otherwise be nice to mark a
storage domain as not usable for new volumes (a bit like the allocatable
option for LVM physical volumes).

[ovirt-users] when creating VMs, I don't want hosted_storage to be an option

[Mike Farnam]

Hi All - Is that a way to mark hosted_storage somehow so that it’s not 
available to add new VMs to?  Right now it’s the default storage domain when 
adding a VM.  At the least, I’d like to make another storage domain the default.
Is there a way to do this?

Thanks
