CentOS 7 to OpenSUSE Migration

1

Hello,

As per this article - https://www.suse.com/c/opensuse-leap-step-by-step-guide-installing-on-your-virtualized-environment/

we are migrating the Cent OS 7 to Open SUSE, but we are getting error PFB ref.

Please further on this.

[root@centos7 yum.repos.d]# virt-install --import --memory 2048 --disk /var/lib/VMs/myopensuseleap.qcow2 --osinfo opensuse15.4 --noautoconsole --name myopensuseleap
usage: virt-install --name NAME --memory MB STORAGE INSTALL [options]
virt-install: error: unrecognized arguments: --osinfo opensuse15.4

virt-install: error: unrecognized arguments: --osinfo opensuse15.5
[root@centos7 yum.repos.d]#

@AbhishekReddy Hi, AFAIK it should auto detect the operating system, so --osinfo should not be needed?

In my Leap 15.5 xml data is: <libosinfo:os id="http://opensuse.org/opensuse/15.5"/>

Thanks.!

I have removed the --osinfo and executed the command and it was installed. PFB ref

But, next step not recevied it. Can you please help further

[root@centos7 yum.repos.d]# virt-install --import --memory 2048 --disk /var/lib/VMs/myopensuseleap.qcow2 --noautoconsole --name myopensuseleap

@AbhishekReddy Hi, I’m guessing --os-variant should be leap155

@AbhishekReddy you need to be running a desktop environment or connect to qemu from another system running a desktop and virt-manager

Dear All,

Can anyone help me CentOS Server to OpenSUSE migration.

13

There is no supported migration of CentOS to openSUSE. You would need to install a new openSUSE machine then manually migrate data and services to it.

14

@AbhishekReddy Why not look at just moving to SUSE Liberty Linux instead?

@malcolmlewis SUSE Liberty will be like a repo server to patch RHEL/CentOS servers.
but, our requirement is, we have multiple centOS servers, planning to migrate to SUSE [OpenSUSE or SLE]

16

@AbhishekReddy Then I would go for SLE and talk with your SUSE Partner on a proper migration strategy (If even possible). Else as indicated by @smflood your going to have to do a fresh install and migrate your services/data over…
