Re: [ovirt-users] oVirt 3.5 & NAT
by Phil Daws
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 Manager that allows one to define an OVS bridge name and VLAN so when a virtual guest is created it can be assigned to the new bridge; with the use of a custom hook.
Thanks, Phil

Darn, looks like this will not work :( the problem is that oVirt creates the bridge ovirtmgmt and binds that to your interface eg. em1. So at that point you have network running. If you then try to add that to the OVS stack your networking stop :( I tried to add it as a port using ovs-vsctl add-port ovsbr0 ovirtmgmt which is accepted but then networking stops. As soon as I remove again networking comes back to life. There does not seem to be a way to have two co-existing bridges :( Thanks, Phil

exactly! You could just make a hook script that runs an after_network_setup
hook that does the ovs-vsctl for you ;-)
Here you can see the presentation I gave last February at devconf about extending
with configurators and hooks.
http://blog.antoni.me/devconf14/#/8/1
I linked directly to a before_network_setup hook sample, because it works just like
the after_network_setup hook. Instead of logging to systemd, just add that if
'remove' is not in data and network == 'ovirtmgmt', it adds the network bridge to
the vswitch with python's subprocess.call or subprocess.check_output.
You can send it if you want me to take a look ;-)
PS: It is possible to write the hooks in bash, c, perl, etc. But we only have the
convenience read_json methods and such for python. If you wanted to, you could have
a simple bash hook that just checked if there was an ovirtmgmt bridge and it would
add it doing ovs-vsctl in the before_vdsm_start hooking point. That would have the
drawback that changing the ovirtmgmt bridge with oVirt UI would leave it disconnected
again.

all-in-one updated from 3.4.4 to 3.5.0 ok with reinstall of host part
by Gianluca Cecchi
On a fedora 19 system where I had 3.4.4 all-in-one, I was able to upgrade
to 3.5.
vdsm part had problems I was able to solve reinstalling host from the
webadmin gui
Steps were:
- follow instructions for engine part --> ok
- verify connectivity of engine via new webadmin
- put host into maintenance
- stop vdsmd service
- yum update vdsm part and all other packages related to ovirt
When trying to start vdsm again I got
[root@tekkaman vdsm]# systemctl status vdsmd
vdsmd.service - Virtual Desktop Server Manager

net_persistence = ifcfg
even after reboot only supervdsm.log was populated...
Nevertheless a host reinstall from webadmin gui seemed to fix the problem
and after that it was able to start vdsm ad host part.
I was also able to upgrade DC/Cluster from 3.4 to 3.5 version.
Now that I'm on 3.5 next days I'll try to pass from F19 to F20... we'll see

oVirt 3.5 & NAT
by Phil Daws
Hello All!
Am really enjoying experimenting with oVirt but have come across a question; how does one enable NAT for a VM ? Would like my guests to be able to update their software by bridging the host public IP. I could not see anything in the WUI to allow this ?
Thanks, Phil

Re: [ovirt-users] oVirt Node 3.5 20140912 for the TestDay
by Raul Laansoo
Hi.
I have got the same issue (filesystems read-only) when provisioning CentOS 6.5 as node host (installed base OS and added vdsm package). multipathd shows wwids file reaed-only. Cant't write wwid.
Fore some reason filesystem gets corrupted when installing vdsm.
Regards.

Deleting large snapshots blocks the whole cluster
by Stefan Wendler

Hi,
we have some really large snapshots left from a migration. Since our
store is almost full now we have to delete them now.
Some snapshots are around 1TB already.
The last time we tried to delete a ~500GB snapshot the delete task
blocked the whole diskstore's IO and the whole cluster and all hosts
became unavailable.
Is there a way to delete large snapshots in a "humane" way that will not
block everything?
Cheers,
Stefan

Problem installing hosted engine on CentOS 7 host
by Justin Clacherty
Hi,
I'm just trying to set up ovirt 3.5 for testing and am unable to get hosted engine installed. The problem appears to be something to do with multipath iscsi setup. I run 'hosted-engine --deploy' and answer all the questions. See the config preview below.
--== CONFIGURATION PREVIEW ==--
Engine FQDN : ovirt.domain.local
Bridge name : ovirtmgmt
SSH daemon port : 22
Firewall manager : iptables
Gateway address : 192.168.42.254
Host name for web application : hosted_engine
iSCSI Target Name : iqn.2014-10.storage.domain.san0:iscsi0
iSCSI Portal port : 3260
Host ID : 1
iSCSI LUN ID : 0
Image size GB : 25
iSCSI Portal IP Address : 10.50.0.200
iSCSI Portal user : myuser
Console type : vnc
Memory size MB : 4096
MAC address : 00:16:3e:23:b4:c2
Boot type : cdrom
Number of CPUs : 2
ISO image (for cdrom boot) : /tmp/CentOS-7.0-1406-x86_64-DVD.iso
CPU Type : model_Nehalem
At the iscsi target question it shows both target names (for each of the multipath options) but you only seem to be able to choose one. After confirming the settings above I get the following.
[ INFO ] Generating answer file '/etc/ovirt-hosted-engine/answers.conf'

The /dev/mapper leads me to believe it's a multipath issue. I noticed this Bugzilla entry when looking into the issue so it appears at least one other person is experiencing the same issue.

Import FC Storage as iSCSI
by Raul Laansoo
Hello.
I have created an FC Storage Domain and made snapshots of all LUNs on the SAN. Now I want to use those snapshots on another Data Center over iSCSI connection to test recovery. I can import the domain, but the domains Storage Type is FC and I can't attach it to host. Is it possible to change domain type to iSCSI or some other way to import storage domain.
Thank you.

Re: [ovirt-users] vmware type functionality

> Hi, Thanks for that. I understand I can see that, but in vmware we sometimes get orphaned VMs that the portal loses for one reason or another and you have to register the with the system again. Or If I move to some new storage and have to copy the VMs to the new storage and then reregister them with a new storage domain - I normally browse the datastore in VMware for the vmx config file and then I can reregister it... But maybe Ovirt when you present a new storage domain just sees the VMs and you don't have to register? I haven't been down this route - well I sort of was, but also if I have VMs on a storage domain and say want to connect it to another data center, can I non-destructively do that? Sorry, kind of a steep learing curve I've been on for the last couple of weeks.
You should keep the users list cc'ed so everybody with the same
questions can find the answers too :)
Well I never have seen "lost" vms in ovirt, but if you want to move
vms between storage domains afaik the only way to currently do so
is to export a vm from a data domain to an export domain and than
import from this export domain to another data domain.
export domains are basically nfs storage systems, so you want to make
sure your firewall and selinux settings are correct.
it's also possible to detach export domains, tar them
and then untar them in another ovirt einvironment and import
this whole export domain (use the "-S" flag if you have "sparse" vms!).
this should also be possible for data domains somehow:
http://www.ovirt.org/Features/ImportStorageDomain
but I didn't try this myself yet, so I don't know if this really
works yet (new features tend to need a point release until they
are matured enough ;) )
