Re: [ovirt-users] Install oVirt with directly-attached SCSI devices

2016-04-09 Thread Rik Theys 

Hi Paolo,

If your storage is detected by multipathd as a multipath capable device
(it should, even if connected through only one connection), oVirt will
detect it as "fibre channel" storage and selecting that as the storage
type should work.

We use a similar setup (with Dell powervault storage)  and haven't had 
any problems with it.


Regards,

Rik

Recently our infrastructure was updated and I'm planning to use oVirt
as virtualisation manager. The new "toys" they gave me are

 - HP DL360G9 (x2)
 - HP MSA1040 (double controller with mini SAS connection)

By exploring the oVIrt documentation, seems that the best solution for
storage management would be having something like NSF, iSCSI and so
on. Unfortunately, LUNs exposed by our MSA1040 are recognised by the
two DL36G9 as directly-attached SCSI devices.

I asked Google and I found this old post from the far 2013

  http://lists.ovirt.org/pipermail/users/2013-November/017924.html

that seems to be very similar to my case and the scenario is not rosy... :-(

Is now, in 2016, something changed? Have you something to suggest?

Do you see the luns exposed by this storage on both hosts?

The output of "lsblk" and "multipath -ll" may be helpful.

If you do, you can treat them as FC storage, and create a FC storage domain
with these luns.

[ovirt-users] R: Re: Autostart VMS

2016-04-09 Thread Stefano Danzi 
I need this Feature for a similar issue. You can see my last post on this ML. 
(VM that has to run on a host in a remote site)

Oggetto: Re: [ovirt-users] Autostart VMS 


I'd like to see the autostart feature as well. In my case I need to autostart a 
virtual router VM at remote site. The issue is that oVirt can't see the remote 
host until the virtual router is started on this host. So HA is not an option.

See this long standing bug:

https://bugzilla.redhat.com/show_bug.cgi?id=1166657

also searching this ML for "autostart" and "VM"

turns up this same discussion every few months.

sadly no dev seems to grasp the importance of this feature, so it's
always rationalsed that it's not needed or the HA feature is enough (it
isn't).

I don't know why the already implemented libvirt autostart feature
does not get simply passed through.

This feature was at least requested by 4 or 5 different people, to no avail.

you might CC yourself to the bugreport(RFE) and vote on it, maybe
this way it will get some traction.

kind regards
