<div>
<div>Hello again,</div>
<div><br>
</div>
<div>Setting the folder permissions to vdsm:kvm (36:36) done the trick to make NFS work. I wasn't expecting this to work since it does not make sense to me, making a parallel with the iSCSI problem.</div>
<div><br>
</div>
<div>I'm starting to believe that's something just bad. Perhaps the Storage system is running with something broken or the host machine is just unstable.</div>
<div><br>
</div>
<div>I will consider this as solved, since further inside the oVirt Engine panel I was able to mount and use the same iSCSI sharing.</div>
<div><br>
</div>
<div>But let me ask for sincere answers here:</div>
<div><br>
</div>
<div>1. oVirt is feature complete comparing to RHEV?</div></div></div></div></blockquote><div><br></div></span><div>Yes. In fact it may have additional features unavailable in RHV.</div><span class="gmail-"><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto"><div><div>
<div><br>
</div>
<div>2. Should I migrate from XenServer to oVirt? This is biased, I know, but I would like to hear opinions. The folks with @<a href="http://redhat.com" target="_blank">redhat.com</a> email addresses will know how to advocate in favor of oVirt.</div></div></div></div></blockquote><div><br></div></span><div>I don't know, and I don't think (having a @<a href="http://redhat.com" target="_blank">redhat.com</a> email myself) I should advocate.</div><div>If someone made a comparison (even if it's just for their own specific use case), it could be great if it could be shared. If you do - please share your thoughts.</div><span class="gmail-"><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto"><div><div>
<div><br>
</div>
<div>3. Some "journalists" says that oVirt is like Fedora in comparison to RHEL, is this really true? Or it's more aligned with a CentOS-like release? Because Fedora isn't really an Enterprise OS, and I was looking for an Enterprise Hypervisor. I'm aware that
oVirt is the upstream from RHEV.</div></div></div></div></blockquote><div><br></div></span><div>I'd cautiously say 'in between'. We strive to ensure oVirt is stable, and I believe we make good progress in every release. </div><div>We also make an effort to quickly release fixes (minor releases). That being said, RHV has a longer life cycle, and for example, when oVirt stopped releasing oVirt 3.6.x, Red Hat continued to release minor versions of it.<br></div><div><br></div><div>We have hundreds of oVirt users running it in production, many in large scale, with mission critical workloads.</div></div></div></div></blockquote><div><br></div><div>And probably not surprisingly, oVirt is running oVirt in production: <a href="https://engine-phx.ovirt.org/ovirt-engine/">https://engine-phx.ovirt.org/ovirt-engine/</a></div><div>for all the oVirt Ci infrastructure (13 hosts, 200 VMs).</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><div><br></div><div><div>Lastly, oVirt enables features in upstream before they are delivered in RHV. </div></div><div><br></div><div>(That being said, I've had a very good experience with Fedora 24 which was rock solid for me, then I've had some misfortune with Fedora 25, and now I'm assessing if I should upgrade to F26 beta...)</div></div></div></div></blockquote><div><br></div><div>For what it's worth, I'm on Fedora 26 since April 14th and works like a charm for me.</div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><span class="gmail-"><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto"><div><div>
<div><br>
</div>
<div>4. There is any good SPICE client for macOS? Or should I just use the HTML5 version instead?</div></div></div></div></blockquote><div><br></div></span><div>I'm afraid not.</div><span class="gmail-HOEnZb"><font color="#888888"><div>Y.</div></font></span><div><div class="gmail-h5"><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto"><div><div>

<div>I will remap uid and gid of NFS to 36 and try again with NFS sharing.</div>
<div><br>
</div>
<div>But this does not make much sense, because on iSCSI this should not happen. There are no permissions involved and when oVirt runs the hosted-engine setup it creates the ext3 filesystem on the iSCSI share without any issue. Here’s a photo of the network
bandwidth during the OVF deployment: <a href="http://www.if.ufrj.br/~ferrao/ovirt/bandwidth-iscsi-ovf.jpg" target="_blank">

</div>
<div>So it’s appears to be working. Something happens after the deployment that brokes the connections and kills vdsm.</div>

<div><br>
</div>
<div>Indeed - may be two different issues. Let us know how the NFS works first, then let's try with iSCSI.</div>

<div>Hello oVirt folks.<br>
<br>
I’m a traitor of the Xen movement and was looking for some good alternatives for XenServer hypervisors. I was aware of KVM for a long time but I was missing a more professional and appliance feeling of the product, and oVirt appears to deliver exactly what
I’m looking for.<br>
<br>
Don’t get me wrong, I’m not saying that Xen is not good, I’m looking for equal or better alternatives, but I’m starting to get frustrated with oVirt.<br>
<br>
Firstly I’ve tried to install the oVirt Node on a VM in VMware Fusion on my notebook, it was a no go. For whatever reasons I don’t know vdsmd.service and libvirtd failed to start. I make sure that I was running with EPT support enabled to achieve nested virtualization,
but as I said: it was a no go.<br>
<br>
So I’ve decommissioned a XenServer machine that was in production just to try oVirt. The hardware is not new, but’s it’s very capable: Dual Xeon E5506 with 48GB of system RAM, but I can’t get the hosted engine to work, it always insults my hardware: --- Hosted
Engine deployment failed: this system is not reliable, please check the issue,fix and redeploy.<br>
<br>
It’s definitely a problem on the storage subsystem, the error is just random, at this moment I’ve got:<br>
<br>
[ ERROR ] Failed to execute stage 'Misc configuration': [-32605] No response for JSON-RPC StorageDomain.detach request.<br>
<br>
But on other tries it came up with something like this:<br>
<br>
No response for JSON-RPC Volume.getSize request.<br>
<br>
I was thinking that the problem was on the NFSv3 server on our FreeNAS box, so I’ve changed to an iSCSI backend, but the problem continues.</div>

At this point I really don’t know what I should try. And the log file is too verborragic (hoping this word exists) to look for errors.<br>

Any guidance?<br>
