[ovirt-users] Re: VLANs with one NIC in ovirt

[Robert Webb]

How is your switch port configured?

The switch port, in your case, would have to be set up in trunk mode, for the 
vlan 5 tagging, then also have a native vlan defined, for the untagged 
management packets.

Hi Joseph, I did that but the problem is that I have an ovirtmgmt network by 
default and another network that is a VLAN, VLAN 5 exactly. But VMs that are in 
VLAN 5 cannot go outside. Maybe it could be because the traffic on ovirtmgmt is 
unlabeled and on VLAN 5 it is tagged. Or maybe I have to create some internal 
route so that VLAN 5 packets can exit on ovirtmgmt. I don't know what exactly 
happens and I would like to help me.

If the route to outside is via untagged network, VLAN 5 should not able to
reach outside.

Yes.

This would break the isolation between VLAN5 and ovirtmgmt.
Do you want to separate VLAN5 from ovirtmgmt?

Maybe you know already what happens, I just did not get your intention.

You can have separate layer 2 networks using VLANs, which are isolated.
They could be connected via a router, which can be a physical device, a
machine outside oVirt or
even an oVirt VM which has a vNIC for each network.

Most simple would be to connect the VMs to ovirtmgmt, but this way the VMs
could harm the physical hosts.

[Staniforth, Paul]

Hello Vijay,
as the error suggests Windows 8 onward defaults to not 
doing a full shutdown but fast boot, this is why in Windows troubleshooting 
it's suggested to do a reboot as this does a full shutdown then boot.
You should probably disable fast-boot on the Windows guest.

Yes. So did you do that?

I'm using QLX, and despite being sluggish, when you tune windows for best 
performance -it is workable.

Of course, if you passthrough a GPU, performance will be completely different.

[ovirt-users] Issue deploying self hosted engine on new install

[Robert Webb]

Hi all,

I am trying to deploy the self hosted engine via cockpit and it is failing at 
the very end of deployment when it is checking the VM Health. I have done 
multiple clean installs and run this and it fails every time.

I have also tried from the cli via ssh with the same outcome.

After the failure, if I look at the oVirt Machines section of the node, the VM 
is there but will not start.

Anyone else having this issue?

[ovirt-users] Re: Importing a Virtual Machine from a KVM Host

[Staniforth, Paul]

Hello Dirk,
The link you are using is old developer docs, try the following.
https://www.ovirt.org/documentation/admin-guide/chap-External_Providers.html

You need to setup an external provider and use a proxy host in the datacentre 
(not the engine host) you want to import into, this needs to be on the same 
network as your KVM host and have the virt-v2v package installed.

   Paul S.

Subject: [ovirt-users] Importing a Virtual Machine from a KVM Host

Hello everbody,

i am just a little bit confused about importing Qemu Images from my KVM Host.

At home, and at work i am using a ovirt engine in a VM. The Version is 4.3.7 
and on bare metal my host.

Everything works fine but i have the same problem at home and on work. I want 
to import my qcow2 Images from a KVM Host but i

will not work.

The command  virsh -r -c 'qemu+tcp://r...@host1.example.org/system' list --all 
shows me akk my VMs.

But when i want to load the images in the GUI, nothing happens. I follow this 
instruction:

https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovirt.org%2Fdevelop%2Frelease-management%2Ffeatures%2Fvirt%2FKvmToOvirt.htmldata=02%7C01%7Cp.staniforth%40leedsbeckett.ac.uk%7C44f2fc1e1e5644fbc17008d7797444c4%7Cd79a81124fbe417aa112cd0fb490d85c%7C0%7C0%7C637111412591121899sdata=L0oVqmTjUoaYQlpmIN8AK9JjNvq8ZVVMP0LQusnbsuU%3Dreserved=0

After that, i take a look on the official 4.3 Rhev Documentation from Red Hat. 
There stand this:

Log in to the proxy host and generate SSH keys for the vdsm user.

sudo -u vdsm ssh-keygen

So, i have no proxy host.  So i want to do this on my ovirt-engine. Is this 
right?

Next thing: the user vdsm is locked on the ovirt-engine machine and the host.

So, do i have to unlocked the account of the user vdsm or what is the best way.

My Problem is i found nothing that would help me to solve this problem.

Maybe somebody here do me a favour and help me to solve this "challenge"

Regards

Dirk
