Re: [ovirt-users] Change ovirtmgmt ip from dhcp to static in a
Indeed very odd, this shouldn't behave this way, just tested it my self and it is working as expected. Unless i miss understood you here, do you use a different IP address when switching to static or the same IP that you got from dhcp? if yes, then this is another flow.. Can you please share the vdsm version and vdsm log with us? Edy, any idea what can cause this? On Tue, Mar 20, 2018 at 11:10 AM, zois roupas <roupas_zois@hotmail.com> wrote:
Hi Michael and thanks a lot for the time
Great step by step instructions but something strange is happening while trying to change to static ip. I tried to do the change while the host was in maintenance mode and in activate mode but again after some minutes the system reverts to the ip that dhcp is serving!
What am i missing here? Do you have any ideas?

Hello Zois,
It pretty easy to do, via the webadmin UI , go to Hosts main tab > Choose host > go to 'Network Interfaces' sub tab > Press the 'Setup Host Networks' button > press the pencil icon on your management network > and choose Static IP > press OK and OK to approve the operation.
- Note that in some cases, specially if this is a SPM host you will loose connectivity to host for few seconds and host may go to non-responsive state, on a non-SPM host usually this woks without any specific issues.
- If the spoken host is a SPM host, I recommend to set it first to maintenance mode, do the switch and then activate. For non-SPM host this will work fine as well when the host is UP.

Hello everyone
I've made a rookie mistake by installing ovirt 4.2 in centos 7 with dhcp instead of a static ip configuration. Both engine and host are in the same machine cause of limited resources and i was so happy that everything worked so well that i kept configuring and installing vm's ,adding local and nfs storage and setting up the backup!
As you understand i must change the configuration to static ip and i can't find any guide describing the correct procedure. Is there an official guide to change configuration without causing any trouble?
I've found this thread http://lists.ovirt.org/ pipermail/users/2014-May/024432.html but this is for a hosted engine and doesn't help when both engine and host are in the same machine
Thanx in advance

One thing to note if you are changing the IP to different one that was assigned by DHCP you should uncheck "Verify connectivity between Host and Engine". This makes sure that the engine won't lost connectivity and in case of switching IP it happens. On Tue, Mar 20, 2018 at 10:15 AM, Michael Burman <mburman@redhat.com> wrote:

Then you need to remove the host from engine, change the IP manually on the host, via ifcfg-file, restart network service and install the host again via the new IP address. On Tue, Mar 20, 2018 at 2:50 PM, zois roupas <roupas_zois@hotmail.com> wrote:
Hi again all,

To answer your question Michael , i'm trying to configure a different ip outside of my dhcp pool. The dhcp ip is 10.0.0.245 from the range 10.0.0.245-10.0.0.250 and i want to configure the ip 10.0.0.9 as the hosts ip
"One thing to note if you are changing the IP to different one that was assigned by DHCP you should uncheck "Verify connectivity between Host and Engine""
Ales, i also tried to follow your advise and uncheck the "Verify connectivity between Host and Engine" as proposed. Again the same results, it keeps reverting to previous dhcp ip I will extract the vdsm log and i'll get back to you, in the meanwhile this is the error that i see after the assignment of the static ip in the log

One thing to note if you are changing the IP to different one that was assigned by DHCP you should uncheck "Verify connectivity between Host and Engine". This makes sure that the engine won't lost connectivity and in case of switching IP it happens.

Hi Michael and thanks a lot for the time
Great step by step instructions but something strange is happening while trying to change to static ip. I tried to do the change while the host was in maintenance mode and in activate mode but again after some minutes the system reverts to the ip that dhcp is serving!
What am i missing here? Do you have any ideas?

Hello Zois,
It pretty easy to do, via the webadmin UI , go to Hosts main tab > Choose host > go to 'Network Interfaces' sub tab > Press the 'Setup Host Networks' button > press the pencil icon on your management network > and choose Static IP > press OK and OK to approve the operation.
- Note that in some cases, specially if this is a SPM host you will loose connectivity to host for few seconds and host may go to non-responsive state, on a non-SPM host usually this woks without any specific issues.
- If the spoken host is a SPM host, I recommend to set it first to maintenance mode, do the switch and then activate. For non-SPM host this will work fine as well when the host is UP.
Cheers)

Hello everyone
I've made a rookie mistake by installing ovirt 4.2 in centos 7 with dhcp instead of a static ip configuration. Both engine and host are in the same machine cause of limited resources and i was so happy that everything worked so well that i kept configuring and installing vm's ,adding local and nfs storage and setting up the backup!
As you understand i must change the configuration to static ip and i can't find any guide describing the correct procedure. Is there an official guide to change configuration without causing any trouble?
I've found this thread http://lists.ovirt.org/ pipermail/users/2014-May/024432.html but this is for a hosted engine and doesn't help when both engine and host are in the same machine
Thanx in advance

If you changing the host's management IP address then this is the only way to do it. If you have only one host in the cluster, then you will need to shut them down :( On Wed, Mar 21, 2018 at 12:08 AM, zois roupas <roupas_zois@hotmail.com> wrote:

Then you need to remove the host from engine, change the IP manually on the host, via ifcfg-file, restart network service and install the host again via the new IP address.

Hi again all,
"Unless i miss understood you here, do you use a different IP address when switching to static or the same IP that you got from dhcp? if yes, then this is another flow.."
To answer your question Michael , i'm trying to configure a different ip outside of my dhcp pool. The dhcp ip is 10.0.0.245 from the range 10.0.0.245-10.0.0.250 and i want to configure the ip 10.0.0.9 as the hosts ip
"One thing to note if you are changing the IP to different one that was assigned by DHCP you should uncheck "Verify connectivity between Host and Engine""
Ales, i also tried to follow your advise and uncheck the "Verify connectivity between Host and Engine" as proposed. Again the same results, it keeps reverting to previous dhcp ip I will extract the vdsm log and i'll get back to you, in the meanwhile this is the error that i see after the assignment of the static ip in the log

One thing to note if you are changing the IP to different one that was assigned by DHCP you should uncheck "Verify connectivity between Host and Engine". This makes sure that the engine won't lost connectivity and in case of switching IP it happens.

Indeed very odd, this shouldn't behave this way, just tested it my self and it is working as expected. Unless i miss understood you here, do you use a different IP address when switching to static or the same IP that you got from dhcp? if yes, then this is another flow..
Can you please share the vdsm version and vdsm log with us?
Edy, any idea what can cause this?

Hi Michael and thanks a lot for the time
Great step by step instructions but something strange is happening while trying to change to static ip. I tried to do the change while the host was in maintenance mode and in activate mode but again after some minutes the system reverts to the ip that dhcp is serving!
What am i missing here? Do you have any ideas?

Hello Zois,
It pretty easy to do, via the webadmin UI , go to Hosts main tab > Choose host > go to 'Network Interfaces' sub tab > Press the 'Setup Host Networks' button > press the pencil icon on your management network > and choose Static IP > press OK and OK to approve the operation.
- Note that in some cases, specially if this is a SPM host you will loose connectivity to host for few seconds and host may go to non-responsive state, on a non-SPM host usually this woks without any specific issues.
- If the spoken host is a SPM host, I recommend to set it first to maintenance mode, do the switch and then activate. For non-SPM host this will work fine as well when the host is UP.
Cheers)

Hello everyone
I've made a rookie mistake by installing ovirt 4.2 in centos 7 with dhcp instead of a static ip configuration. Both engine and host are in the same machine cause of limited resources and i was so happy that everything worked so well that i kept configuring and installing vm's ,adding local and nfs storage and setting up the backup!
As you understand i must change the configuration to static ip and i can't find any guide describing the correct procedure. Is there an official guide to change configuration without causing any trouble?
I've found this thread http://lists.ovirt.org/ pipermail/users/2014-May/024432.html but this is for a hosted engine and doesn't help when both engine and host are in the same machine
Thanx in advance
