External networks issue after upgrading to 4.3.6
by ada per
After upgrading to the latest stable version the external networks lost all
functionality. Under providers-->ovn-network-provider the test runs
successfully.
But when im creating an external provider network, attaching it to a router
as a LAN setting up dhcp lease it is not reachable from other VMs in the
same network. Hosts and hosted engine can't seem to ping it either.
I tried disabling firewalls on both hosted engines, VMs and host and still
nothing.
When configuring Logical networks or …
[View More]VLANs they work perfectly tje one
problem is the external networks.
I have another environment running on a previous version of ovirt and it
works perfectly there. I think its a bug.
Thanks for your help

Re: Migrate VM from oVirt to oVirt
by Strahil
You will need a storage that will be your 'USB stick' . For example you can attach NFS-based storage domain, migrate the disks of the VM to that storage.
Then power off that VM, set the storage to maintenance and then detach it from first oVirt engine.
Then you attach and activate that NFS storage in your new oVirt engine. After Activation, there will be an 'Import VMs/templates' tab . Click on it and import the VM in a cluster.
Last step is to migrate your VM's disks from that NFS to their …

restore
by suporte@logicworks.pt
Hi,
I did a backup of engine like this
# engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name
In a newly installed machine try to restore it:
# yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm
# yum update
# yum install ovirt-engine
# engine-backup --mode=restore --file=file_name --log=log_file_name --provision-db --restore-permissions
but get this error:
Start of engine-backup with mode 'restore'
scope: all
archive file: file_name
…
[View More]log file: log_file_name
Preparing to restore:
- Unpacking file 'file_name'
Restoring:
- Files
Provisioning PostgreSQL users/databases:
- user 'engine', database 'engine'
Restoring:
FATAL: Can't connect to database 'ovirt_engine_history'. Please see '/usr/bin/engine-backup --help'.
I'm running ovirt Version:4.3.4.3-1.el7
If I run
# engine-backup --mode=restore --file=file_name --log=log_file_name --provision-db --no-restore-permissions
still the same error
Any idea?
Many Thanks

Does ovirt support sshfs?

Hi All,
Does ovirt support sshfs for mount locally accessible LUN's instead of NFS?

SHE with multipath on multiple iSCSI targets
by Francesco Castellano
Dear sirs,
we're trying to install an SHE oVirt 4.3.6 using an iSCSI SAN that provides
us multiple targets (8) over 4 different portals. Following 5.1 of "RHV
installation using Cockpit" we set up iscsi and multipath ahead with a 90GB
LUN to be used for the engine VM. Unfortunately, even if the node OS sees
correctly the LUN, e.g.:

during the engine deploy neither via cockpit nor with "hosted-engine
--deploy" it was able to see any LUN.
Having a lot of portals (4) and each having 4 targets (two of which being
independents path to the LUN), we chose a portal to discover, it proposed
us 4 targets, and we had to choose a target to log in, but in the end, no
LUN was proposed.
After a few attempts, we found that, if we logged out from any targets (and
clean up the open-iscsi database), after the login in an appropriate
target, the installer proposed us the LUN, and we successfully deployed the
SHE.
But unfortunately, such an installation doesn't track effectively all the 8
paths over 8 different targets, but just the one chosen during the
installation (this is different, for example, with respect to other LUNs
for data domains that we attached afterwards). Thus we miss the HA we aimed
to for the engine data domain.
I said this, because when I ask for /ovirt-engine/api/storagedomains,
whilst a second LUN has 8 children with different targets
below storage_domain/${another data
domain}/storage/volume_group/logical_units/logical_unit/, for the
hosted_storage I just have one.
My questions are:
a) is there a way to add the other targets/paths consistently (even through
the REST interface)?
b) is there another installation, or recovery, procedure to get the engine
data domain in high availability on our iSCSI topology?
Thank you so much for your suggestions, they are really appreciated,
Best regards,
Francesco Castellano

Quick question regarding FQDN
by Christian Reiss
Hey folks,
for production use quality it is recommended to have backend (storage)
and front end seperated. Let' assume:
- 85.0.0.0/24 public IP block
- 10.100.0.0/24 private IPs for DC internal usage
- 10.200.0.0/24 private IPs for storage only LAN
and running, as per recommendation 3 nodes:
- node01:
- fqdn: node01.dc-example.com
- fqdn storage: node02.storage.example.com
- no public IP
- 10.100.0.1 primary IP
- 10.200.0.1 storage IP
- node02:
- fqdn: …
[View More]node02.dc-example.com
- fqdn storage: node02.storage.example.com
- no public IP
- 10.100.0.2 primary IP
- 10.200.0.2 storage IP
- node03:
- fqdn: node03.dc-example.com
- fqdn storage: node02.storage.example.com
- no public IP
- 10.100.0.3 primary IP
- 10.200.0.3 storage IP
The storage network is its own physical network with 10gig that only
connects those three servers. How can I specify which IP to use for
storage, which for frontend traffic?
I am assuming this as the controller and all admins should be able to
reach the nodes via frontend, which is not the storage one.
Okay, I am lost. Whats the real solution here?
Or is "frontend" no-ip, just VM traffic and "backend" is the 10gig
storage "Only" where all the FQDN reside?
Thanks for clarification,
-Chris.

I want to configure an web server
by Istiaque Islam
Hi there,
I have installed oVirt on a server and related ISO and Data domains.
I can create Virtual Machines and that machine get access to internet to
download things.
What I want to do now :
1. create an web server using centos and access that webserver from
anywhere with internet connection
2. Then I shall configure a domain name for that webserver hosted in oVirt
Virtual Machine.
My Question :
How to configure the virtual machine in oVirt so that when I enter my
specified domain name/IP …
[View More]it will hit that particular virtual machine?
As it is a virtual machine, it will not get any public IP, so how should i
configure the virtual machine set up so that it can be used as an web
server.
Thanks in advance.
