Re: [ovirt-users] Upgrade 4.0.6 to 4.1.1 -- How to Update oVirt Node (4.x) Hosts?

[Beckman, Daniel]

Hello,

I’m not trying to run nodectl myself; in fact I was not familiar with the 
command until the error popped up at every login. As I mentioned earlier:

> So it looks like it’s been invoked from here:
> ls -llh /etc/profile.d/nodectl*

> According to ‘yum whatprovides’ this appears to have been installed by

This is how those scripts are trying to run it:
[root@labovirt host-deploy]# cat /etc/profile.d/nodectl-motd.sh
nodectl motd
[root@labovirt host-deploy]# cat /etc/profile.d/nodectl-run-banner.sh
nodectl generate-banner

Thanks,
Daniel

Looks like something went wrong during the update process, can you please 
attach /tmp/imgbased.log ?
Regarding nodectl, I'm not sure, adding Ryan.  Basically, it's a python 2.7 
module, not sure why it's running in python3.  How are you trying to run this ?

You mean you do that after the above (removing 4.0 repos, adding 4.1)?

What packages did it update?

Please check also time-wise nearby log files for this host in
/var/log/ovirt-engine/host-deploy and share them.
'ovirt-host-mgmt*' is the result of checking for updates from the admin web ui.

Re: [ovirt-users] Hello from Bacchus !

[Beckman, Daniel]

Hi Niyazi,

Thanks for sharing with the community! There is definitely a need for this.

Just curious -- do you have plans to allow direct exporting of a VM snapshot? 
That would eliminate one copy operation.

Best,
Daniel

[ovirt-users] Upgrade 4.0.6 to 4.1.1 -- How to Update oVirt Node (4.x) Hosts?

[Beckman, Daniel]

So I successfully upgraded my engine from 4.06 to 4.1.1 with no major issues.

A nice thing I noticed was that my custom CA certificate for https on the admin 
and user portals wasn’t clobbered by setup.

I did have to restore my custom settings for ISO uploader, log collector, and 
websocket proxy:
cp /etc/ovirt-engine/isouploader.conf.d/10-engine-setup.conf. 
/etc/ovirt-engine/isouploader.conf.d/10-engine-setup.conf
cp 
/etc/ovirt-engine/ovirt-websocket-proxy.conf.d/10-setup.conf. 
/etc/ovirt-engine/ovirt-websocket-proxy.conf.d/10-setup.conf
cp 
/etc/ovirt-engine/logcollector.conf.d/10-engine-setup.conf. 
/etc/ovirt-engine/logcollector.conf.d/10-engine-setup.conf

Now I’m moving on to updating the oVirt node hosts, which are currently at 
oVirt Node 4.0.6.1. (I’m assuming I should do that before attempting to upgrade 
the cluster and data center compatibility level to 4.1.)

When I right-click on a host and go to Installation / Check for Upgrade, the 
results are ‘no updates found.’ When I log into that host directly, I notice 
it’s still got the oVirt 4.0 repo, not 4.1. Is there an extra step I’m missing? 
The documentation I’ve found 
(http://www.ovirt.org/documentation/upgrade-guide/chap-Updates_between_Minor_Releases/)
 doesn’t mention this.


**
If I can offer some unsolicited feedback: I feel like this list is populated 
with a lot of questions that could be averted with a little care and feeding of 
the documentation. It’s unfortunate because that makes for a rocky introduction 
to oVirt, and it makes it look like a neglected project, which I know is not 
the case.

On a related note, I know this has been discussed before but…
The centralized control in Github for the documentation does not really 
encourage user contributions. What’s wrong with a wiki? If we’re really 
concerned about bad or malicious edits being posted, keep the official in git 
and add a separate wiki that is clearly marked as user-contributed.

Re: [ovirt-users] Upgrading oVirt-Node-NG from 4.0.3 to 4.0.6

[Beckman, Daniel]

I’ve noticed something that may be related. I have two hosts that had 4.03 
installed from the ISO (from console of the host), and two with 4.0.4 (also 
from an ISO). At various points since going from engine 3.6 to 4.04 to 4.05, 
we’ve had the ‘upgrade available’ message pop up on all 4 hosts, and in each 
case I’ve put the host in maintenance mode and let it run the ‘upgrade’. They 
don’t generate any errors; they reboot and report a finished upgrade. But they 
still report as being 4.03 and 4.04 hosts.

When I manually run ‘yum update’ from any of the hosts, they report ‘no 
packages marked for update’.

Update – After looking more closely, it looks like most repos are disabled on 
the hosts. I’m not sure how it got to that state as I never would have disabled 
them:

Re: [ovirt-users] oVirt VM backup and restore

[Beckman, Daniel]

We’re been using oVirtBackup with our oVirt 4.0.5 environment and it’s worked 
well. It’s not the most efficient ( first creates a snapshot, then clone, then 
backup) but we can live with it.

Has anyone tested oVirtBackup with oVirt 4.1? Does it still work? I want to 
know before we upgrade. I’d like to eventually use the new v4 API but I haven’t 
seen a lot of documentation on how it works in practice.

Thanks,
Daniel

[ovirt-users] oVirt Engine Default Web Page - Broken Link "Console Client Resources"

[Beckman, Daniel]

I just noticed that the default web page for oVirt engine 
(http:///ovirt-engine/), at 
least for version 4.0.5, now has a broken link:

Console Client 
Resources

Is this true of 4.06 or was it fixed? What about 4.1? Can someone who’s 
upgraded to those versions check?

Daniel already filed two bugs:

https://bugzilla.redhat.com/1416533
https://bugzilla.redhat.com/1416579

I CCed on them Christophe, the maintainer of spice-nsis, on which
ovirt-wgt is based, and he very quickly posted a patch to spice-devel.

I pushed the patch also to our gerrit, so jenkins will do a test build:

https://gerrit.ovirt.org/71226

http://jenkins.ovirt.org/job/ovirt-wgt_master_create-rpms-fc24-x86_64_created/22/

Daniel, can you please try the test build and report whether it works
for you? Thanks!
Also asked you on one of the bugs. Feel free to reply wherever is most
convenient.

Re: [ovirt-users] Configuring an ISO domain in RHEV 4.0

[Beckman, Daniel]

Hi Paul,

Run this:
chown 36:36 /var/lib/exports/iso

Try adding it again in RHEV/oVirt manager. When you add it, it will create a 
directory structure underneath your NFS share – something like /images/----/, which is where you need to 
put the ISO (or VFD for floppy images) files. And be sure they’re always owned 
by 36:36. If you use engine-iso-uploader it will handle that for you.

Subject: [ovirt-users] Configuring an ISO domain in RHEV 4.0


I'm trying to get an ISO domain configured in a new RHEVM manager. I did not 
configure it during the initial ovirt-engine-setup, and am manually configuring 
it after the fact.

I created an NFS share in /var/lib/exports/iso and dropped a couple of files in 
there from elsewhere, just for testing purposes.

On a client system, I can mount the NFS share, but it appears empty.

On the RHEV manager when I try to add an ISO domain, I get this error message:

"Error while executing action Add Storage Connection: Permission settings on 
the specified path do not allow access to the storage.
Verify permission settings on the specified storage path."

I suspect the selinux permissions aren't set right. This is what they are 
currently configured to:

On the folder itself
[root@hostname iso]# ll -dZ .
drwxr-xr-x. root root system_u:object_r:nfs_t:s0

On the two files in the folder:

[root@hostname iso]# ll -Z
-rwxrw-rw-. root root unconfined_u:object_r:nfs_t:s0 
sosreport-LogCollector-20170117092344.tar.xz
-rwxrw-rw-. root root unconfined_u:object_r:nfs_t:s0 test.txt

Is this correct? If not what should they be set to?

Thanks

Re: [ovirt-users] [ANN] oVirt 4.1.0 First Release Candidate is now available

[Beckman, Daniel]

I tested this on a Windows 2012 R2 (x64) DataCenter VM, newly built, on oVirt 
4.0.5. 

It suffers from the same bug that’s been present since at least oVirt 3.6: The 
Balloon service is setup with the wrong path: 

C:\Program Files (x86)\oVirt Guest 
Tools\drivers\Balloon\w2k12R2\amd64\blnsvr.exe"

The correct path being:

C:\Program Files (x86)\oVirt Guest 
Tools\drivers\Balloon\2k12R2\amd64\blnsvr.exe"

Note the small typo: “w2k12R2” when the actual files are under “2k12R2”. The 
fix is much the same as before:

sc config BalloonService binpath= "C:\Program Files (x86)\oVirt Guest 
Tools\drivers\Balloon\2k12R2\amd64\blnsvr.exe" DisplayName= "Balloon Service" 
start= auto

How is it that this bug persists? Is it being actively tracked? I found 
reference to someone possibly having “a look” but no follow-up:

Hi Andrea

Triple Check

When the path is wrong we get this type of message:

"Windows could not start the Balloon Service on Local Computer.

Error2: The system cannot find the file specified."

But in this case, we get:

"The OVirt Guest Service on Local Computer started and then stopped. Some 
services stop automatically if they are not in use in use by other services or

¿ Maybe a oVirt bug ?

Re: [ovirt-users] Scheduled Snapshot and export

[Beckman, Daniel]

Strangely enough, I can’t reproduce that issue in 4.0.5. 

Anantha, when you say “will not allow us to change anything” what exactly do 
you mean?

Does it generate the same “unhandled exception” error as when adding disks or 
something else? 

I was able to specify 4 vCPUs consisting of 2 sockets (each with dual core) and 
it worked fine.

Re: [ovirt-users] Scheduled Snapshot and export

[Beckman, Daniel]

I don’t know of a function built into oVirt for scheduling snapshots. If you 
don’t already you may want to setup an export domain (NFS based), on separate 
storage.

Just a reminder: snapshots are not backups and they should only be kept 
temporarily. We use this tool for backups:

https://github.com/wefixit-AT/oVirtBackup

It’s not the most efficient as it clones a VM from a snapshot, then exports the 
clone – so you’re transferring the same data twice. But it works for our 
purposes. We have this running in a cron job.

If anyone has come up with a script that uses the newer API to export a 
snapshot directly, please share!

We get the same error when adding a disk while creating the VM (In Chrome, 
Firefox, and Safari on OS X Sierra client). This is reportedly fixed in 4.0.6 
per this bug:

https://bugzilla.redhat.com/show_bug.cgi?id=1394175

Could someone with 4.0.6 confirm that?

Daniel

Hello to oVirt Users,
I have few questions.


a. Can we schedule the VM snapshots? If yes, please share the procedure
b. Snapshots are stored on the same storage domain. Can we move them to another 
storage domain say NFS domain for additional safety? If, yes, please share the 
procedure.

Also, after upgrading to version 4.0.5, at many places, especially when we are 
creating a new VM and trying to create a new Disk for the VM, we keep getting 
"uncought exception" and the process will not complete. We have to create a VM, 
without Disk and then create the disk separately and attach it to VM.

Is anyone else facing this issue? These sort of issues were not there in 4.0.4.

Re: [ovirt-users] Import Virtual Machines From Web Admin GUI

[Beckman, Daniel]

I indeed followed that procedure, including confirming I could SSH into the KVM 
host as user ‘vdsm’ without being prompted for a password. I had specified the 
host name of the KVM host, not the IP (though at one point I also tried the IP, 
with same results.) 

I was curious so on the KVM (source) host I added entries in /etc/hosts for all 
of the hypervisors in oVirt, along with the oVirt engine host for good measure 
(probably not necessary).

I tried another import, this time withouth the “no_verify=1” and it worked 
without error. 

Our internal DNS works – all of the hosts were able to correctly resolve 
addresses prior to me editing /etc/hosts. But I guess something in that process 
does not query DNS. 

Anyway, at least that’s a cleaner solution than removing verification. 

Thanks,
Daniel

Hi,

I'm sort of puzzled why you still saw "Host key verification failed" if
you followed the procedure (or the steps described in [1]).

https://www.ovirt.org/develop/release-management/features/virt/XenToOvirt/


Only thing I can think of is that you used IP of the KVM host during the
procedure but then you used hostname in the URL (in import dialog).

Another possible problem could be that there were two conflicting host
keys in known_hosts file. But I believe adding "no_verify=1" would not
help in this case.

[ovirt-users] VM Import from Admin GUI: "VM has MAC address(es) , which is/are out ouf its MAC pool definitions"

[Beckman, Daniel]

I recently completed a VM import from a standard KVM host (Centos 7 based) to 
oVirt 4.0.5. The import completed fine and the VM runs and operates as 
expected. But I got the error cited in subject. Here’s the complete unedited 
error:

VM thays-puppet-svr has MAC address(es) 52:54:00:ce:2b:7d, which is/are out ouf 
its MAC pool definitions.

Note that is a direct copy and paste – and note the misspelling for “of” as 
“ouf”.

Will running this VM with a MAC address falling outside of the pool lead to 
problems?

Re: [ovirt-users] Import Virtual Machines From Web Admin GUI

[Beckman, Daniel]

To answer my own question: as is often the case, perusing the commercial (RHV 
4.0) documentation proved useful.

The documentation is here:
https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/paged/virtual-machine-management-guide/612-exporting-and-importing-virtual-machines-and-templates

However, I kept getting the error “Host key verification failed.: Connection 
reset by peer”. This despite having followed the official documentation on 
generating and copying keys, under Procedure 6.2.6 Importing a Virtual Machine 
from KVM.

Then I found this article from July 2012 about a different (but similar) 
scenario:

https://access.redhat.com/solutions/136463

What helped was the “alternative test” suggestion. Here is the URI I ended up 
using with success:

qemu+ssh://root@MY_KVM_HOST/system?no_verify=1

Appending “no_verify=1” did the trick. It’s possible that adding hostnames and 
IPs to /etc/hosts would have also resolved this, but for something performed 
infrequently (importing a VM from another environment), modifying the URI is 
easier.

[Beckman, Daniel]

When you edit the “operating system” type of a VM under the General section, 
there are a plethora of operating systems listed, including FreeBSD, Debian, 
SUSE, and older variants of Ubuntu. But there are two glaring exceptions: 
CentOS and Fedora. Is this by design?

It’s worth noting that plain KVM, vSphere, and just about every other VM 
platform supports these (Red Hat sponsored) operating systems. But not oVirt. 
Why?

Sincerely confused,
Daniel

Re: [ovirt-users] ovirt 4.05 windows balloon service installation wrong path

[Beckman, Daniel]

On a somewhat related note, whenever I setup a Windows 2012 R2 VM and then 
install oVirt Tools (the standard one from the oVirt repo -- 
oVirt-toolsSetup_4.0-1.fc23.iso), the oVirt Guest Service fails to start. To 
get things working I have to follow this procedure:
Open Device Manager, right click on each device with a question mark (lacking a 
driver), select "update driver software", "browse my computer", specify your CD 
drive (usually D:\), then hit Next and it should pick up the appropriate driver 
for each device. After that, go to Services (also accessible under Computer 
Management) and try starting oVirt Tools – it show now start OK. Back in the 
oVirt web interface, you should notice there is now information about the VM's 
IP and installed applications.

It’s an old issue – I had to follow the same workaround back in oVirt 3.6 with 
the oVirt 3.x tools. Is there a bug open on this?

Best,
Daniel

Please note it works like this on all server versions of Windows 
(w2k3/w2k8/w2k12/w2k16).
Also the guest tools installer doesn’t install the QEMU service, so it’s 
necessary to run
C:\Program Files (x86)\oVirt Guest Tools\drivers\guest-agent\qemu-ga-x86.exe
manually.

Hello team,
FYI standard installation of Guest tool on Windows server O.S. is somehow 
flawed.
It setups a windows service named “BalloonService” with path
C:\Program Files (x86)\oVirt Guest Tools\drivers\Balloon\w2k8R2\amd64\blnsvr.exe

Unfortunately, the real path created on filesystem is
C:\Program Files (x86)\oVirt Guest Tools\drivers\Balloon\2k8R2\amd64\blnsvr.exe
(please note the missing “w” after \Baloon\ )

Thanks for the report Andrea, checking...


The easy workaround is to run this command on a “run as admin” cmd shell:
sc config BalloonService binpath= "C:\Program Files (x86)\oVirt Guest 
Tools\drivers\Balloon\2k8R2\amd64\blnsvr.exe" DisplayName= "Baloon Service 
Ovirt 4" start= auto

I suggest to fix either the command that create path during installation or the 
one which setup the service

Re: [ovirt-users] Move a VM between 2 setups

[Beckman, Daniel]

Hi Christophe,

An “export domain” is made for just this purpose. Create a NFS (version 3) 
share and make it accessible to the hypervisors for each engine. (It should be 
a dedicated NFS share, not used for anything else.) As I recall it should be 
owned by vdsm:vdsm (36:36). In one of the engines (doesn’t matter which), in 
the web admin page go to Storage and add a new NFS based export domain, using 
the NFS share you created. Once it’s activated, test it out; try right-clicking 
on a VM to “export” it.

Note that there can only be one engine connected to a given export domain at 
any one time. When you’re done testing the export domain on the first engine, 
you need to put it into “maintenance” and ultimately “detach” it.

Then go to the other engine, and this time under Storage instead of “new 
domain” click “import domain” and enter the same NFS share information. It 
should recognize that you already have an export domain setup under that NFS 
share.  Attach and activate it, and under Storage /   
/ VM Import, try importing the VM you had previously exported.

This is covered (sparsely) in the oVirt documentation at 
https://www.ovirt.org/documentation/admin-guide/administration-guide/, and it’s 
covered more coherently in the commercial RHV documentation at 
https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/single/administration-guide#Storage_properties.

Best,
Daniel

Subject: [ovirt-users] Move a VM between 2 setups

Hi,

We have a setup where we want to deploy 2 engines as the network between 2 
buildings is unreliable.

With 2 engines, we then want to be able to move VMs (one time) from current 
engine where they are running to new engine in the other building.

Is there a recommended workflow for doing this?
We have access to shared NFS for this task if required.

Thanks for any pointers,
Christophe

Re: [ovirt-users] oVirt Engine Upgrade 3.6 to 4.0.4 - Next Steps?

[Beckman, Daniel]

Thanks for the suggestions. As I noted, “my hosts are still running oVirt node 
3.6.” As in, I’m not running a general purpose EL7 installation – I’m running 
the stripped down oVirt node 3.6 image which is based on EL7 but can’t be 
upgraded (via yum) as in a normal OS install. After digging through some 
assorted pages (e.g. http://www.ovirt.org/node/) , it looks like oVirt Node has 
undergone an extensive redesign since 4.x . So I’ll rebuild all my hosts.

Thanks,
Daniel

The upgrade process should be performed by upgrading all your clusters first to

The hosts might also need to be upgraded by yum update.
Sandro, correct me if I'm wrong, is there a wiki regarding the Host upgrade 
process?

If the hosts are already EL7 you can upgrade using Upgrade manager 
https://www.ovirt.org/develop/release-management/features/engine/upgrademanager/
Otherwise you'll have to reinstall hosts with EL7 one by one.

For hosted engine you can follow

Re: [ovirt-users] ovirt homeserver

[Beckman, Daniel]

Hi David,

Since you mention this is for testing and learning the technology, I’d go with 
option #2. You’ll lose some performance but that shouldn’t matter for your 
purposes, and you’ll gain a lot of flexibility.

KVM is a basic building block for oVirt and Openstack. It’s a valuable skill 
set to have, even outside of RH based distributions. It’s fairly simple to 
troubleshoot, there’s not so many moving parts. It’s like a reliable old car 
with a stick shift and roll-up windows.

If you only have one physical server at your disposal and you choose option #1, 
then you have to use a self-hosted engine. I personally don’t like the 
self-hosted engine. That could be due to some bad experiences early in its 
history, and maybe it’s much improved with oVirt 4.x.  But I’d much rather have 
a plain old KVM VM (for the oVirt engine) that I can make a clone or snapshot 
of.  That has saved me from rebuilding many times.

I’ve never used GPU pass-through; hopefully someone else can address that.

Yes, CentOS is your best bet; stick with the default kernel. You could use 
Fedora if you’re adventurous but I don’t recommend it. You’ll have the best 
experience if your environment is close to what is supported in the commercial 
product, RHV.

Take advantage of the official RHV documentation, most of which is applicable 
to oVirt upstream.

https://access.redhat.com/documentation/en/red-hat-virtualization/

And have fun!

Subject: [ovirt-users] ovirt homeserver

Hi,
I'm building a homeserver to run ovirt and wanted to get opinions on the best 
approach.
The server will be used as a test/studybed for ovirt/kvm/vcloud/openstack/ceph.
The server will be based around a Xeon E5 10 core with 128GB ram.
Option 1:
Build server with CentOS 7.2 and deploy ovirt directly on top.
Option 2:
Build server with CentOS 7.2 and deploy multiple ovirt instances on top of KVM.
Which will be the most stable versatile method?
If a GPU is used as a passthrough device can it be used on several vm's or is 
it restricted to 1 vm?
If 2 GPU's are used can 1 be used as a dedicated passthrough to 1 vm and the 
other shared between the remaining vm's?
Is CentOS/RH the best platform for ovirt?
Is it okay/advisable to load the latest kernel, (4.8 ish), on to CentOS before 
installing ovirt?

Any and all comments/advice welcome,
David

[ovirt-users] Upgrading oVirt 3.6 with existing HTTPS certificate signed by custom CA to oVirt 4

[Beckman, Daniel]

We have oVirt 3.6.7 and I am preparing to upgrade to 4.0.4 release. I read the 
release notes (https://www.ovirt.org/release/4.0.4/) and noted comment #4 under 
“Install / Upgrade from previous version”:

If you are using HTTPS certificate signed by custom certificate authority, 
please take a look at https://bugzilla.redhat.com/1336838 for steps which need 
to be done after migration to 4.0. Also please consult 
https://bugzilla.redhat.com/1313379 how to setup this custom CA for use with 
virt-viewer clients.

So I referred to the first bugzilla 
(https://bugzilla.redhat.com/show_bug.cgi?id=1336838), where it states as 
follows:

If customer wants to use custom HTTPS certificate signed by different CA, then 
he has to perform following steps:

1. Install custom CA (that signed HTTPS certificate) into host wide trustore 
(more info can be found in update-ca-trust man page)

2. Configure HTTPS certificate in Apache (this step is same as in previous 
versions)

3. Create new configuration file (for example 
/etc/ovirt-engine/engine.conf.d/99-custom-truststore.conf) with following 
content:
ENGINE_HTTPS_PKI_TRUST_STORE="/etc/pki/java/cacerts" 
ENGINE_HTTPS_PKI_TRUST_STORE_PASSWORD=""

4. Restart ovirt-engine service

I find it humorous that step # 1 suggests reading the “man page” which is only 
slightly better than suggesting to “google” it.

Has anyone using a custom CA for their HTTPS certificate successfully upgraded 
to oVirt 4? If so could you share your detailed steps? Or can anyone point me 
to an actual example of this procedure? I’m a little nervous about the upgrade 
if you can’t already tell.

Thanks,
Daniel

Re: [ovirt-users] oVirt 3.6 Migrated from Legacy AD Authentication - Previously Used AD Users Can't Log In

That’s it! Some background: within our IT department most of us have a regular 
user account and an administrative account. For the later account type, the UPN 
and SAM account name happen to be the same (e.g. jdoead...@example.com) whereas 
for regular users UPN is something like john@example..com.  When I used the 
UPN name (e.g. john.doe) the login worked fine. 

We can work with that. But is there a way to change it to using SAM account 
name?

[ovirt-users] oVirt 3.6 Migrated from Legacy AD Authentication - Previously Used AD Users Can't Log In

[Beckman, Daniel]

I have been updating our oVirt 3.6 (3.6.7.5-1) environment in preparation for 
upgrading to oVirt 4.

We had been using the legacy AD connection (via engine-manage-domains), and 
since that’s no longer available in oVirt 4, this was a priorty. (I put this 
off as long as I could – I found the new method a step back in ease of use.)

So following the documentation I setup ‘ovirt-engine-extension-aaa-ldap’, 
connecting to the same Active Directory forest. It seemed to work; I was able 
to look up users. But none of the existing AD users that we had been using in 
oVirt were able to log in to the admin or user portal, using the new extension. 
The error is “General command validation failure.”. (Whereas if you enter a 
wrong password, you get the expected wrong password error.)  Here’s what 
/var/log/ovirt-engine/engine.log shows for “myuser”:

Re: [ovirt-users] Multi cluster question with regards to storage

[Beckman, Daniel]

Hi David,

Storage is associated with a particular data center, so if they are on the same 
data center they will have access to the same storage.

The Red Hat documentation on the commercial supported version RHEV (now RHV?) 
is a lot more comprehensive; the equivalent oVirt documentation is pretty 
sparse and uneven, so it’s understandable you never would have been introduced 
to that concept. You need an active subscription to access the KB articles but 
the basic documentation is freely available and it’s a good resource, as most 
things are going to be common on RHV vs. oVirt:

Subject: [ovirt-users] Multi cluster question with regards to storage

I've not yet found a clean concise answer and so I wanted to ask before I start 
trying to play with things in my test setup and waste a bunch of time maybe.

If I have 2 clusters in one data center each running different cpu types 
(amd/intel) can they both access the same shared storage domain(gluster in my 
case)?

I'm not interested in live migration between the clusters really, though 
stopping and starting on another would be nice.  I've tried looking at various 
threads and list emails and I've found some mentions of it, but usually as an 
aside while discussing other matters so I could never quite say for certain it 
was working or not.
