Re: [ovirt-users] hosted engine deploy failed 3.5 centos 6.5 host FC20 vm

[Alastair Neil]

No need turned out to be pebkac,  I had been using my domain account for so
long I had the wrong admin account thus the hosted-engine failed to
authenticate I have resolved the issue.

Re: [ovirt-users] Snapshot deletion gone horribly wrong - Urgent

[Stefan Wendler]

After exporting some unused VMs and deleting other snapshots afterwards
I'm back to 500GB. But the partially deleted 1TB Snapshot is still there
and needs to be cleaned up.

Is there a clean way to "cleanup" partially deleted/migrated snapshots
without loosing more disk space? What I don't understand is what is
there to migrate, if it is the last snapshot anyway? Shouldn't the
"Actual VM"-disks be in a consistent state with or without the
snapshots? Or asked another way ... are there documents with an in-depth
description on how snapshots work in oVirt?

Cheers,
Stefan

[ovirt-users] Snapshot deletion gone horribly wrong - Urgent

[Stefan Wendler]

Hi,

I'm trying to delete a 1TB snapshot on a store with 1.5TB free space.
should be more than enough and the engine didn't complain.
The snapshot to delete is the only snapshot for this VM.

I started snapshot deletion a couple of hours ago. ovirt then started
filling up the store. I'm sure it happened because of the snapshot
deletion. I have seen this many times when deleting snapshots.
Now I have a couple of KBytes left on the store and the snapshot is
marked as broken. And I cannot delete the snapshot because of not enough
free space. Is there a way to alter the database and then delete the
snapshot files by hand?

I know the files that are the snapshots and could delete them but then
the vm wouldn't start because it is missing the files.

Cheers,
Stefan

I'd welcome any details on this "stalled file descriptor" problem. Is
there a bug filed with some details like logs, sysrq-t and maybe even
tcpdumps? If there is an easy way to reproduce this behaviour, I can
surely look into it and hopefully come up with some advise or fix.

Re: [ovirt-users] webhook

[Koen Vanoppen]

Whoow, just missed a couple of days I see... thanks everybody for your
already given support!! I will discuss this also with my colleague on
Monday. And I must say I'm impressed about all the fedback! This could be
indeed a very nice extension to oVirt, because I guess we are not the only
ones who are in need of this or will be in the future.
Thanks again!

Re: [ovirt-users] oVirt 3.5 & NAT

[Phil Daws]

Is there anybody who can help with this please ?  Am pretty sure all I need to 
be able to do know is create a network hook that changes a VM XML from:

  










  

to something like:

  






  

so replacing the bridge with a network and setting the network to be the OVS 
one I have defined.

Any ideas please ? Thanks, Phil

Am starting to believe may have to give up on oVirt and move back to straight 
KVM and Openvswitch as that just worked which is a real shame :(

I believe am really missing the point somewhere along the line :( on my 
straight KVM and OVS system I see:

brctl show
bridge name bridge id   STP enabled interfaces
virbr0  8000.fe5400552ed9   yes vnet5
vnet8
ovs-vsctl show
55a2af2f-daf5-4f01-a757-9bccaf4f6932
Bridge "ovsbr0"
Port "vnet0"
Interface "vnet0"
Port "vnet1"
tag: 8
Interface "vnet1"
Port "vnet13"
tag: 14
Interface "vnet13"
Port "vnet9"
tag: 10
Interface "vnet9"
Port "mgmt0"
Interface "mgmt0"
type: internal
Port "vnet14"
tag: 8
Interface "vnet14"
Port "ovsbr0"
Interface "ovsbr0"
type: internal
Port "vnet11"
tag: 8
Interface "vnet11"

and on the new oVirt system I see:

brctl show
bridge name bridge id   STP enabled interfaces
;vdsmdummy; 8000.   no  
ovirtmgmt   8000.c81f66c42c76   no  em1
vnet0
ovs-vsctl show
08554d11-3ba7-4303-b9d5-6a09f23c9057
Bridge "ovsbr0"
Port "ovsbr0"
Interface "ovsbr0"
type: internal


so I have the ovirtmgmt bridge running fine and that is responding to traffic.  
If I bond an IP to the ovsbr0 it responds okay:

ip add add 88.XXX.XXX.XXX/29 dev ovsbr0

so network traffic is flowing in and out of OVS.  The next step would be to 
create a VM that will act as the firewall with a public facing interface on 
ovsbr0, but then all internal networks would need specific vlans behind that.  
I have already defined a new network called ovs-network:


  ovs-network
  76152e72-34da-43bc-864a-85e727025bc9
  
  
  
  

  

  
  

  

  
  

  

  
  

  

  
  

  

  
  
  


and then I should just be able to assign the network and vlan IDs to each VM 
NIC:


  
  
  
  


  
  
  
  


so where should I start to put all this together please ? I believe am 90% 
there its just how to get the source-network and port-group to be assigned to a 
VM guest when its built ?  Guess probably need to create a new hook similar to 
https://github.com/oVirt/vdsm/blob/master/vdsm_hooks/macspoof/macspoof_vnic.py 
that changes this in each guests VM definition from bridge to a network:

How does one add multiple custom properties ? tried: 

engine-config -s 
CustomDeviceProperties='{type=interface;prop={vlan=^[a-zA-Z0-9_ 
---]+$}}{type=interface;prop={bridge=^[a-zA-Z0-9_ ---]+$}}' 

but ended up with one call vlan and the other prop :) If can add vlan and 
bridge then should be able to use a vNIC profile for adding an interface 
directly to OVS using a custom hook.

Well, in fact have got something to work now! Left ovirtmgmt and em1 alone but 
ran: 

$ ovs-vsctl add-br ovsbr0 
$ ip link add name veth0 type veth peer name veth1 
$ brctl addif ovirtmgmt veth0 
$ ovs-vsctl add-port ovsbr veth1 
$ ip add add XXX.XXX.XXX.XXX/29 dev veth1 
$ ip link set veth0 up && ip link set veth1 up 

and now veth1 is responding as-well as veth0. 

ovs-vsctl show 
08554d11-3ba7-4303-b9d5-6a09f23c9057 
Bridge "ovsbr0" 
Port "veth1" 
Interface "veth1" 
Port "ovsbr0" 
Interface "ovsbr0" 
type: internal 

so what I think should do now is create a custom parameter on the Engine 
M
