currently we have:

2 hosts (one is running also the oVirt Engine)
1 DC
We are only using NFS storage.

No reports are used. But we have it integrated into our LDAP.

Best regards
Christoph

Hi oVirt List,

I wanted to upgrade our oVirt 3.6.7 installation in the next couple of days to oVirt 4.0.5.
My hosts are running CentOS 7.2 currently. It is safe to perform the upgrade also to CentOS 7.3?

Is 4.0.5 also support this version of CentOS?

It is correct that the upgrade to 4.0 is the same as always?
Just I need to install the new repositories?
I guess I have to delete the old 3.6 repos or not?

Can you give more details, such as:

- how many hosts?
- how many DCs?
- how many= Clusters?
- which kinds of storage domains in use (NFS, iSCSI, F= C, ...)?
- currently using Hosted Engine? Planning to use it in u= pgraded environment?
- currently using reports and dwh and if so,= currently using which database for them?
- other custom configur= ation aspects?

The more you give in advance the more other users can share abou= t their experience.

In general this guide for RHEV should be of help for oVirt too:<= /div>

Hi Gianluca,

currently we have:

2 hosts (one is running also the oVirt Engine)
1 DC
We are only using NFS storage.

No reports are used. But we have it integrated into our LDAP.

Best regards
Christoph

Hi oVirt List,

I wanted to upgrade our oVirt 3.6.7 installation in the next couple of days to oVirt 4.0.5.
My hosts are running CentOS 7.2 currently. It is safe to perform the upgrade also to CentOS 7.3?

Is 4.0.5 also support this version of CentOS?

It is correct that the upgrade to 4.0 is the same as always?
Just I need to install the new repositories?
I guess I have to delete the old 3.6 repos or not?

Can you give more details, such as:

- how many hosts?
- how many DCs?
- how many= Clusters?
- which kinds of storage domains in use (NFS, iSCSI, F= C, ...)?
- currently using Hosted Engine? Planning to use it in u= pgraded environment?
- currently using reports and dwh and if so,= currently using which database for them?
- other custom configur= ation aspects?

The more you give in advance the more other users can share abou= t their experience.

In general this guide for RHEV should be of help for oVirt too:<= /div>
https://access.redhat.com/documentation/en/red-hat-virtuali= zation/4.0/paged/upgrade-guide/

HIH as a first insight,

Gianluca
=C2=A0
As the environment is simple I can try to si= mulate, probably next week, as an exercise, as I have to migrate a similar = test environment then.
I= 'll let you know.
Plain ldap o= r freeipa or what? I will test with freeipa as shipped in CentOS 7.2 with u= pdates (not yet upgraded to 7.3)

Hi Gianluca,

no quite plain. We are connecting to a openldap server.

Hi Gianluca,
currently we have:

2 hosts (one is running also the oVirt Engine)
1 DC
We are only using NFS storage.

No reports are used. But we have it integrated into our LDAP.

Hi oVirt List,

I wanted to upgrade our oVirt 3.6.7 installation in the next couple of days to oVirt 4.0.5.
My hosts are running CentOS 7.2 currently. It is safe to perform the upgrade also to CentOS 7.3?

Is 4.0.5 also support this version of CentOS?

It is correct that the upgrade to 4.0 is the same as always?
Just I need to install the new repositories?
I guess I have to delete the old 3.6 repos or not?

= Best regards and thank you for your answers Christoph

Can you give more details, such as:

- how many hosts?
- how many DCs?
- how many= Clusters?
- which kinds of storage domains in use (NFS, iSCSI, F= C, ...)?
- currently using Hosted Engine? Planning to use it in u= pgraded environment?
- currently using reports and dwh and if so,= currently using which database for them?
- other custom configur= ation aspects?

The more you give in advance the more other users can share abou= t their experience.

In general this guide for RHEV should be of help for oVirt too:<= /div>
https://access.redhat.com/documentation/en/red-hat-virtuali= zation/4.0/paged/upgrade-guide/

HIH as a first insight,

Gianluca
=C2=A0
As the environment is simple I can try to si= mulate, probably next week, as an exercise, as I have to migrate a similar = test environment then.
I= 'll let you know.
Plain ldap o= r freeipa or what? I will test with freeipa as shipped in CentOS 7.2 with u= pdates (not yet upgraded to 7.3)

Just as a counterpoint, I had 2 issues, but both were related to changes I'd made.. - I have ipv6 disabled. with CentOS 7.3 this can cause rpcbind to choke, causing cascading dependency failures. I had to manually tweak systemd config. - I had tweaked vdsm.conf for debugging a long time ago, so the new version installed it's conf file as vsdm.conf.rpmnew. New vdsm uses a different logger, and wouldn't start with the old logger config. No error message, 0 byte log file. Copying rpmnew conf file over existing log files fixed this one.
