I=92m a traitor of the Xen movement and was looking for some good alternati= ves 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 oVir= t appears to deliver exactly what I=92m looking for. Don=92t get me wrong, I=92m not saying that Xen is not good, I=92m looking = for equal or better alternatives, but I=92m starting to get frustrated with= oVirt. Firstly I=92ve 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=92t know vdsmd.serv= ice and libvirtd failed to start. I make sure that I was running with EPT s= upport enabled to achieve nested virtualization, but as I said: it was a no= go. So I=92ve decommissioned a XenServer machine that was in production just to= try oVirt. The hardware is not new, but=92s it=92s very capable: Dual Xeon= E5506 with 48GB of system RAM, but I can=92t 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=92s definitely a problem on the storage subsystem, the error is just ran= dom, at this moment I=92ve got: [ ERROR ] Failed to execute stage 'Misc configuration': [-32605] No respons= e 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=92ve changed to an iSCSI backend, but the problem continues. Can't say anything about your issues without the logs but there's nothing w= rong 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, whic= h leads me to believe that=92s an oVirt issue. The OVA was already copied a= nd deployed to the storage: [ INFO ] Starting vdsmd [ INFO ] Creating Volume Group [ INFO ] Creating Storage Domain [ INFO ] Creating Storage Pool [ INFO ] Connecting Storage Pool [ INFO ] Verifying sanlock lockspace initialization [ INFO ] Creating Image for 'hosted-engine.lockspace' ...
