[ovirt-users] Host keeps disconnecting

[Chris Cowley]

Hello all

I am trying out ovirt 4 on a single host using the hosted engine. All
storage is on the same machine, with NFS3 in the middle.

Regularly the host disconnects from the engine - although all the VMs
continue working happily. I can re-activate it immediately and it will come
online happily, I can then manipulate VMs to my hearts content for a few
minutes until it disconnects again and I have to re-activate it.

First, am I being stupid trying to run this on a single node? Am I obliged
to at least break out the storage in to a seperate node/NAS

Second, assuming this is technically possible, where should I be looking
for clues?

Re: [ovirt-users] I wrote an oVirt thing

[Chris Cowley]

While I really like both ideas it is not a route I would PERSONALLY 
take.


To me it seems logical that there should be parallels between oVirt and 
Openstack. After all, oVirt already integrates with Glance, Cinder and 
Neutron. Thus it is not unreasonable to suggest that any sort of CLI 
should take its inspiration from the Openstack CLI tools.


Also, I am not sure that would scratch my personal itch - which even in 
its unbelievably primitive state, my tool does.


Of course, this is FLOSS, so knock yourself out - the more the merrier.

Looks cool.

But I think what we need is something like targetcli for ovirt.
http://linux-iscsi.org/wiki/Targetcli#Display_the_object_tree

With such tool we can see the ovirt setup as a file system tree:

/ovirt/vms/vm-id
/ovirt/storage/domain-id
...

And be able to query and operate on the entities.

Another crazy direction I discussed with Roy, is a fuse files system 
mapping

ovirt setup to a file system - imagine:

$ mount -t ovirtfs /ovirt

$ ls /ovirt/vms
vm-id-1
vm-id-2
...

$ cat /ovirt/vms/vm-ids/running
1

$ echo 0 > /ovirt/vms/vm-id/running

Hi all

I started hacking together something last night to use as a CLI to
manage my oVirt clusters.

https://gogs.chriscowley.me.uk/chriscowley/ovirtmanage

Currently it can create/delete a VM, list the VMS, and I started a
function to show the details, but all that does for now is return 
the ID.


The plan is for it to evolve with my own needs, but I am open to
ideas/PRs from the community.

Disclaimer #1: I am a SysAdmin, not a developer. If you a proper
developer, what you see may cause you physical pain.

Disclaimer #2: My Gogs repo is behind my ADSL in rural France, be
patient and I withold the right to not respect any sort of SLA :-)

Re: [ovirt-users] I wrote an oVirt thing

[Chris Cowley]

Don't see what Ansible has to do with this. In any case, I do not
actually like Ansible. It is not a tool that follows my logic, nor do I
like that it always seems to nudging me towards Ansible Tower.

I wanted a simple CLI that I can use to scratch my own personal itch and
thought I would share it with you guys.

[ovirt-users] Problem creating ovirtmgmt bridge

[Chris Cowley]

I am installing on a 3 node cluster, with gluster as my storage. Each node
has a pair of bonds. At the moment, my intention is to use bond0 for all VM
traffic, with management (and thus ovirtmgmt) on bond1 along with Gluster
(bond1..

Sadly hosted-engine --deploy dies saying:

```
Failed to execute stage 'Misc configuration': Failed to setup networks
{'ovirtmgmt': {'ipaddr': u'10.110.84.11', 'netmask': u'255.255.255.0',
'bonding': 'bond1', 'bootproto': u'none', 'gateway': u'10.110.84.1',
'defaultRoute': True}}. Error code: "-32603" message: "Attempt to call
function: > with arguments: ({u'ovirtmgmt': {u'ipaddr': u'10.110.84.11',
u'bonding': u'bond1', u'netmask': u'255.255.255.0', u'bootproto': u'none',
u'gateway': u'10.110.84.1', u'defaultRoute': True}}, {},
{u'connectivityCheck': False}) error: 'NoneType' object is not iterable"
```

Is my way of configuring my network even possible? Or do I need to re-think
things

[ovirt-users] disk image uploading

[Chris Cowley]

Simple question:

Is there a better way of uploading a disk to a storage domain than through
my browser?

[ovirt-users] Kill a failed VM import

[Chris Cowley]

Hello all

I have just imported physical machine into my export datastore using
virt-p2v. While I was importing it, my hosted-engine died (VM went into
paused state) during the disk-copy stage.

Now, that half-imported VM is in the status "image locked" and I am un able
to do anything with it. The disk image does not seem to be in my master
data store so I think I can safely delete the VM and re-import it. However,
that is not available in the web GUI. How can I work around that and force
the deletion?
