Combining Virtual machine image with multiple disks attached
by kkchn.in＠gmail.com
I have few VMs in Redhat Virtualisation environment RHeV ( using Rhevm4.1 ) managed by a third party
Now I am in the process of migrating those VMs to my cloud setup with OpenStack ussuri version with KVM hypervisor and Glance storage.
The third party is making down each VM and giving the each VM image with their attached volume disks along with it.
There are three folders which contain images for each VM .
These folders contain the base OS image, and attached LVM disk images ( from time to time they added hard disks and used LVM for storing data ) where data is stored.
Is there a way to get all these images to be exported as Single image file Instead of multiple image files from Rhevm it self. Is this possible ?
If possible how to combine e all these disk images to a single image and that image can upload to our cloud glance storage as a single image ?
Is this possible or Am I asking a Stupid question which theoretically not possible ?
Thanks in Advance for sharing your thoughts,
Kris.

Restored engine backup: The provided authorization grant for the auth code has expired.
by Nicolás
Hi,
I'm restoring a full ovirt engine backup, having used the --scope=all
option, for oVirt 4.3.
I restored the backup on a fresh CentOS7 machine. The process went well,
but when trying to log into the restored authentication system I get the
following message which won't allow me to log in:
The provided authorization grant for the auth code has expired.
What does that mean and how can it be fixed?
Thanks.

Accessing the oVirt Console Remotely
by louisb＠ameritech.net
I've installed ovirt on the my server (HPDL380Gen10) and was able to start the configuration process on the local machine. I'm tried to access the ovirt console remotely via the web however I've had no success. I'm using the same URL that is used locally, but when I execute the URL via my Firefox browser I get the message that it is unable to connect. I've drop the firewall on both the server and client machine as a possible solution but it did not work.
Is there something extra that is needed to access the ovirt console remotely?
The FQDN is entered into my DNS, however, I did find that during the configuration process that IP was consumed by ovirtmgmt. I was surprised to see that I'm just assuming that its apart of congiruation process. I have other ports on my sever and I have entered them in my DNS also with the same name but a different IP address.
What must I do to gain access to the ovirt console remotely, it would surely make the configuration process easy from my desk vs being in the server area.
Thanks

Host not becoming active due to VDSM failure

Hello,
I have a host that's failing to bring up VDSM, the logs don't say anything specific, but there's a Python error about DHCP on it. Is there anyone with a similar issue?

There is little difference in CPU performance between these three scenarios,
so why distinguish between high performance and regular virtual machines? I
don't think it makes much sense.

The provided authorization grant for the auth code has expired.
by Nicolás
Hi,
A time ago I posted a similar question and I couldn't get it solved. I
couldn't spend more time on this up until now, so I'm trying again and
having the same error, which I'm unable to fix. I would really
appreciate some help since I cannot find any documentation for this.
I'm restoring a full ovirt engine backup, having used the --scope=all
option, for oVirt 4.3.
I restored the backup on a fresh CentOS7 machine. The process went well,
but when trying to log into the restored authentication system I get the
following message which won't allow me to log in:
The provided authorization grant for the auth code has expired.
What does that mean and how can it be fixed?
I'm also attaching a screenshot.
Thanks.

Question about cloud-init
by tommy
Hello, I have a question about cloud-init:
After installing vm, I installed cloud-init immediately, and enabled its
four services, and then I can use cloud-init in the admin interface.
However, I don't know how cloud-init knows where to get the relevant
information (such as host name, SSH secret key, etc.) that I configured on
the admin interface ? For I haven't configured the data source for
cloud-init.
Why it can works ?
Thanks!
