Hello Adam and Karli,

I will remap uid and gid of NFS to 36 and try again with NFS sharing.

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: 
http://www.if.ufrj.br/~ferrao/ovirt/bandwidth-iscsi-ovf.jpg

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

Thanks,
V.

Hello oVirt folks.

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.

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.

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.

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.

It’s definitely a problem on the storage subsystem, the error is just random, 
at this moment I’ve got:

[ ERROR ] Failed to execute stage 'Misc configuration': [-32605] No response 
for JSON-RPC StorageDomain.detach request.

But on other tries it came up with something like this:

No response for JSON-RPC Volume.getSize request.

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.

Can't say anything about your issues without the logs but there's nothing wrong 
with FreeNAS (FreeBSD) NFS, I've been running oVirt with FreeBSD's NFS since 
oVirt 3.2 so...

Could you share your relevant exports configuration to make sure he's using 
something that you know works?


"You're holding it wrong":) Sorry, I know you're frustrated but that's what I 
can add to the conversation.

/K

This happens at the very end of the ovirt-hosted-engine-setup command, which 
leads me to believe that’s an oVirt issue. The OVA was already copied and 
deployed to the storage:

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.

Any guidance?

Thanks,
V.
