So does this mean I shouldn't bother with installing otopi, because
according to the development guide for RPM-based systems, it seems
only the ovirt-host-deploy, ovirt-setup-lib, and ovirt-js-dependencies
are the packages required. The guide for Debian is blank and marked as
TODO. Another query I had was that should I make the config files
myself as referenced by the README or can I expect that it will be
done during make install?

Re: [ovirt-users] storage redundancy in Ovirt

[Dan Yasny]

When you set up a storage domain, you need to specify a host to perform the
initial storage operations, but once the SD is defined, it's details are in
the engine database, and all the hosts get connected to it directly. If the
first host you used to define the SD goes down, all other hosts will still
remain connected and work. SPM is an HA service, and if the current SPM
host goes down, SPM gets started on another host in the DC. In short,
unless your actual NFS exporting host goes down, there is no outage.

 In my view NFS is much easier to manage than any other type of storage,
 specially FC and iSCSI and performance is pretty much the same, so you
 won`t get better results other than management going to other type.

Hi Fernando,
I see each host has direct connection nfs mount, but yes, if main host to
which I connected nfs storage going down the storage becomes unavailable
and all vms are down

 Hi guys,
 I have one nfs storage,
 it's connected through host1.
 host2 also has access to it, I can easily migrate vms between them.

 The question is - if host1 is down - all infrastructure is down, since
 all traffic goes through host1,
 is there any way in oVirt to use redundant storage?

 Only glusterfs?

 Thanks

Re: [ovirt-users] storage redundancy in Ovirt

[Charles Kozler]

I think he means SPM? I've seen when node with SPM goes down it isn't
really seamless and takes a minute or two to catch up unless of course you
out that node in maintenance mode but that isn't possible if it crashes or
something

Hello Konstantin.

That doesn`t make much sense make a whole cluster depend on a single host.
>From what I know any host talk directly to NFS Storage Array or whatever
other Shared Storage you have.
Have you tested that host going down if that affects the other with the NFS
mounted directlly in a NFS Storage array ?

Re: [ovirt-users] storage redundancy in Ovirt

[Konstantin Raskoshnyi]

In ovirt you have to attach storage through specific host.
If host goes down storage is not available.

You can use FC storage where luns come from a redundant storage array.

[ovirt-users] Memory ballooning not working on RHEV 4.1?

[Joseph Chapman]

Hello all,

I have a RHEV 4.1 host running Windows 10 VMs. I have installed the balloon
driver on the VMs (RHEV guest tools), and enabled memory ballooning on the
cluster using RHEV-M. On the VMs, I have set the system memory to Memory
Size: 4GB, Maximum Memory: 16GB.

While I can manually hot plug memory, I am not seeing additional memory
being automatically allocated to the VMs during a SQL workload. The
documentation for RHEV 4.1 is not clear on whether or not this automatic
ballooning is functional (earlier documentation suggests that it is
functional only by use of an API).

I am new to RHEV and would appreciate some help troubleshooting this.
Please let me know if there's any additional information I should provide.
I messaged this mailing list on suggestion from someone in the IRC. I hope
this is in-bounds.

Thanks for your time!
