I am in the process of testing oVirt to replace ESXi 6 and have run into some issues that I haven't found answers to.  I've used ESXi for quite a while and done some work with Microsoft's Hypervisor but am new to oVirt.  It looks like it has potential to replace the others but there are some major issues I'm trying to work through.  I'm using a hosted-engine deployment.  The host is a guest on VMware Workstation 11 on Windows.  Not the best but it lets me test oVirt. I've created the VM, the engine is installed, the webadmin works, and I can SSH to it but I'm seeing some things that I haven't been able to find answers to so any help is appreciated.  I'm using DNS to resolve and both the engine and host can ping each other, reverse lookup on their names works. 1.  I used an iSCSI LUN on a NAS for storage during the deploy install but this storage does not show up in the admin portal list of storages.  Is it supposed to?  It's being used as it now has 3+ our of 50 gig used. 2. I used a local directory on the VM for an initial ISO domain but it does not show up in the admin portal.  I have more than 15 Gig of space available.  Shouldn't it be showing up in the list of storages?  I tested using this (http://www.ovirt.org/documentation/how-to/troub leshooting/troubleshooting-nfs-storage-issues/) and from the host I can mount the engine's exported directory and create a file in it as the vdsm user. 3. My host wants confirmation it's rebooted which it has been both with hosted-engine vm-shutdown/vm-start, and rebooting from within the engine.  If I tell it to confirm I get the message below.  Well, it's status is running.  i can't connect when it's connecting or non- operational!!  I've put the system into maintenance mode with hosted- engine commands, I used the context menu on the hosted-engine vm in the portal to put it into maintenance but it still refuses to confirm it's rebooted.  Any ideas on how to get it confirmed.  I've also rebooted the hosted-engine host with no change. "Error while executing action: Cannot confirm 'Host has been rebooted' Host. Valid Host statuses are "Non operational", "Maintenance" or "Connecting"." 4.  My Default Data Center is uninitialized which is probably why nothing works.  If I use guide me and attach the hosted_engine choice it tells me it cannot acquire a host id.  I restarted the sanlock service and then when I attached the storage the dialog hung up spinning it's wheel and never returned.  I restarted the VM from hosted-engine and still get the AcquireHostId failure.  The iSCSI lun is being used and accessed by the engine as there is 3+ gig of space used.  If I try and attach the hosted_engine storage the icon changes to a wrench, then back to the red down arrow and I get the error about not acquiring a host id.  What host id?   I only have one host!  I've reinitialized the lockspace all with no effect.  The /var/log/ovirt-engine/engine.log has this error.  What invalid argument? I've seen some bug reports on this but they are back in version 3.3 or so and are supposed to be fixed.

This is how it currently works. This is because the hosted_storage domain can't be used as the "master storage domain", and such as master is required for many things.

Did this solve all your problems? If not, please: 1. Try again with 3.6.3, which should be out in a few days, or the latest RC [1]. 2. If you still have problems, please state versions of OSes and whatever other relevant tools, and post (links to) full logs of both the host and the engine: /var/log/ovirt* /var/log/vdsm* [1] http://lists.ovirt.org/pipermail/users/2016-February/038125.html

I'd suggest that there be some indication that > we need to add a master storage domain. Perhaps. Actually we are trying to get rid of it: https://www.ovirt.org/develop/release-management/features/storage/decommi... > Is the master storage domain the same one used to store VMs or can it > be a separate domain which is used only as the master and VMs go > elsewhere. Does is need a minimum amount of storage space? Normally it's the first "normal" data domain, used to store VMs. Not sure about minimum size if you do not intend to store VMs there. I guess it can be very small - a few MBs or so.

Thank you for the explanation. That helps. The hypervisors I used in the past had no such thing. You just created storage areas and used them as desired and the admin interface worked whether or not they existd.
