Adding more detailed reproduction steps here:
1)Reprovisioned to fresh 4.1 RHEVH.
2)This is the defaults on host:
[root@alma03 ~]# cat /etc/ovirt-host-deploy.conf.d/90-ngn-do-not-keep-networkmanager.conf
[environment:init]
VDSM/disableNetworkManager=bool:True
3)Changed to not to turn off the NM and rebooted:
[root@alma03 ~]# vi /etc/ovirt-host-deploy.conf.d/90-ngn-do-not-keep-networkmanager.conf
[root@alma03 ~]# cat /etc/ovirt-host-deploy.conf.d/90-ngn-do-not-keep-networkmanager.conf
[environment:init]
VDSM/disableNetworkManager=bool:False
[root@alma03 ~]# reboot
Connection to alma03.qa.lab.tlv.redhat.com closed by remote host.
Connection to alma03.qa.lab.tlv.redhat.com closed.
4)Once rebooted, checked that value stayed False:
# cat /etc/ovirt-host-deploy.conf.d/90-ngn-do-not-keep-networkmanager.conf
[environment:init]
VDSM/disableNetworkManager=bool:False
5)Manually installed rhvm-appliance-4.1.20170126.0-1.el7ev.noarch on host.
6)Started the HE deployment over NFS from Cockpit.
7)Hosted Engine Setup successfully completed!
cat /etc/ovirt-host-deploy.conf.d/90-ngn-do-not-keep-networkmanager.conf [environment:init]
VDSM/disableNetworkManager=bool:False

In UI you will also see that under "Name" of the host "localhost.localdomain" will appear. This bug report has Keywords: Regression or TestBlocker. Since no regressions or test blockers are allowed between releases, it is also being identified as a blocker for this release. Please resolve ASAP. Did you ever encounter this issue? This issue does not happen not for 3.6RHEVH, not for 4.0RHEVH, but only for 4.1RHEVHs on all four hosts. I don't see here any infrastructure issue. I suspect that NM is setting the hostname based on the DHCP response but we do not support that using ifcfg. Please collect and provide the the following information from the host before deploying it: - ifcfg files. - nmcli con show <connection name on which the management IP is set> After the deploy, we need the same ifcfg files, to check the differences. The hostname is changed to localhost much earlier, no need to wait for HE setup to end.
Once vdsm configuring the management bridge it's changing to localhost.
If restarting network service, the hostname is back to correct hostname.

Edy, if you were correct, then restart to network wouldn't bring the hostname back.
A few seconds after "systemctl restart network", it looks like NM overrides the hostname. From the messages log: Feb 15 17:58:01 localhost systemd: Started LSB: Bring up/down networking.

But on RHEVH it seems this is not the case, triggering this problem. I think we should check if this can be changed in parallel to the problem fix needed from NM. (In reply to Nikolai Sednev from comment #6) > This issue does not happen not for 3.6RHEVH, not for 4.0RHEVH, but only for > 4.1RHEVHs on all four hosts. > I don't see here any infrastructure issue. The only change in 4.1 RHV-H is that NetworkManager is on. I'd expect the root cause to be somewhere inside NM (and for this to be reproducible on RHEL-H hosts with NM running). RHV-H does not touch/change hostnamectl (or anything related to networking), and we haven't since 4.x. Unfortunately, I don't have time to try to get a reproducer today. But I would expect this bug to be elsewhere. Can you please post the contents of /etc/hostname on RHEL and RHV-H systems? If they differ, how is /etc/hostname being set on the RHEL systems? Kickstart? Manually? Yihui, could you help on comment 5? Weiwang, could you help on comment 5 due to yzhao is on PTO these days. My reproduce steps:
1. Install RHVH4.1 via PXE
2. use cmd "hostname" and "cat /etc/hostname"
#hostname
dell-per730-34.lab.eng.pek2.redhat.com
#cat /etc/hostname
localhost.localdomain
3. The cockpit display the hostname "localhost.localdomain", so I modify the hostname to "dell-per730-34.lab.eng.pek2.redhat.com" via cockpit.
4. vi /etc/ovirt-host-deploy.conf.d/90-ngn-do-not-keep-networkmanager.conf
cat /etc/ovirt-host-deploy.conf.d/90-ngn-do-not-keep-networkmanager.conf
[environment:init]
VDSM/disableNetworkManager=bool:False
5. Reboot
6.Deploy HE successfully
After step6,

(In reply to Yaniv Dary from comment #5) > Did you ever encounter this issue? According to comment #15, we cannot encounter this issue again. (In reply to Wei Wang from comment #16) > (In reply to Yaniv Dary from comment #5) > > Did you ever encounter this issue? > > According to comment #15, we cannot encounter this issue again. Comment #15 has set the hostname statically, which is a workaround to the problem reported in this BZ. In case a user expects the hostname to be retrieved dynamically from DHCP, he may not set the hostname statically on cockpit (or elsewhere). Summarizing this BZ status and proposing a workaround to lower severity: The problem has been detected in the steps of acquiring interfaces from NetworkManager by VDSM. When NM is unmanaging an interface, it will cleanup the interface from all its setting and the VDSM through ifcfg initscript will take over and redefine it again. NM has a unwanted behaviour of overwriting the hostname, even through the hostname has been retrieved by the ifcfg initscript on an interface that is not managed by NM. This only occurs if the static hostname has not been set, depending solely on the transient hostname (from dhcp). A host with no static hostname has been seen only on RHV-H. NM BZ has been open on this: https://bugzilla.redhat.com/show_bug.cgi?id=1422610 As a *workaround*, the user can set the static hostname manually (from cockpit for example, see comment #15). Please confirm that the workaround is working out for you so we can suggest documenting it (if NM fix will not be available). 1)alma04.qa.lab.tlv.redhat.com's password: node status: OK See `nodectl check` for more information Admin Console: https://10.35.117.26:9090/ or https://2620:52:0:2340:a236:9fff:fe3b:167c:9090/ 2)[root@alma04 ~]# hostname alma04.qa.lab.tlv.redhat.com 3)[root@alma04 ~]# cat /etc/hostname localhost.localdomain 4)The cockpit display the hostname "localhost.localdomain", so I've modified the hostname to "alma04.qa.lab.tlv.redhat.com" via cockpit. 5)Restarted from cockpit. 6)Before HE deployment, once host rebooted "systemctl status NetworkManager -l" ● NetworkManager.service - Network Manager Loaded: loaded (/usr/lib/systemd/system/NetworkManager.service; enabled; vendor preset: enabled) Active: active (running) since Wed 2017-02-22 14:34:42 IST; 1min 58s ago Docs: man:NetworkManager(8) Main PID: 974 (NetworkManager) CGroup: /system.slice/NetworkManager.service ├─ 974 /usr/sbin/NetworkManager --no-daemon └─1089 /sbin/dhclient -d -q -sf /usr/libexec/nm-dhcp-helper -pf /var/run/dhclient-p1p1.pid -lf /var/lib/NetworkManager/dhclient-81e02010-5b23-46d0-a51c-58e7c6ebde5b-p1p1.lease -cf /var/lib/NetworkManager/dhclient-p1p1.conf p1p1 Feb 22 14:34:55 alma04.qa.lab.tlv.redhat.com NetworkManager[974]: <info> [1487766895.4422] dhcp4 (p1p1): gateway 10.35.117.254 Feb 22 14:34:55 alma04.qa.lab.tlv.redhat.com NetworkManager[974]: <info> [1487766895.4422] dhcp4 (p1p1): server identifier 10.35.64.1 Feb 22 14:34:55 alma04.qa.lab.tlv.redhat.com NetworkManager[974]: <info> [1487766895.4422] dhcp4 (p1p1): lease time 86400 Feb 22 14:34:55 alma04.qa.lab.tlv.redhat.com NetworkManager[974]: <info> [1487766895.4422] dhcp4 (p1p1): nameserver '10.35.64.1' Feb 22 14:34:55 alma04.qa.lab.tlv.redhat.com NetworkManager[974]: <info> [1487766895.4422] dhcp4 (p1p1): nameserver '10.35.255.6' Feb 22 14:34:55 alma04.qa.lab.tlv.redhat.com NetworkManager[974]: <info> [1487766895.4422] dhcp4 (p1p1): domain name 'qa.lab.tlv.redhat.com' Feb 22 14:34:55 alma04.qa.lab.tlv.redhat.com NetworkManager[974]: <info> [1487766895.4423] dhcp4 (p1p1): state changed unknown -> bound Feb 22 14:34:55 alma04.qa.lab.tlv.redhat.com NetworkManager[974]: <info> [1487766895.4444] policy: set 'p1p1' (p1p1) as default for IPv4 routing and DNS Feb 22 14:34:55 alma04.qa.lab.tlv.redhat.com dhclient[1089]: bound to 10.35.117.26 -- renewal in 32727 seconds.

Given the simple workaround, this should not be a 4.1-blocker. This bug report has Keywords: Regression or TestBlocker. Since no regressions or test blockers are allowed between releases, it is also being identified as a blocker for this release. Please resolve ASAP. (In reply to Dan Kenigsberg from comment #20) > Workaround for this bug: before deploying Hosted Engine, modify the hostname > to fully-qualified domain name via cockpit. > > Given the simple workaround, this should not be a 4.1-blocker. So can we move it to 4.1.2? 4.1.3? I'm happy with keeping this as a 4.1.1 exception, so we give it higher immediate priority. But nothing horrible would happen if we solve this only in 4.1.3. (I attempted to drop the blocker flag in comment 21, but the robots were stronger than me) Update: Can reproduce the issue. After deploy HE successfully, we should reboot RHVH host, and the hostname change to "localhost.localdomain". [root@localhost ~]# hostname localhost.localdomain Additional info: If we install RHVH4.1 ,and add the host to engine ,then reboot RHVH host, the hostname don't change. When asking kickstart to set host name, we are not affected by this, hence reducing severity. Hi, I tried to install RHVH 4.1 and after installation, the hostname was localhost.localdomain though the host was getting IP and hostname from the DNS at the time of installation. After installation completes, the hostname was localhost.localdomain and I observed that the network was not UP because ONBOOT parameter was set to "no" and the interface did not come up to get IP / Hostname assigned. After editing ONBOOT=yes and reboot, the host was able to take the IP and hostname correctly. This is before adding the host to RHVM. (I am not sure if this is relevant, Just wanted to share my observations) Michael, now that rhel-7.4 and NetworkManager-1.8.0-0.4.rc1.el7 is out, can you re-verify this bug? Since this showed up in a HostedEngine-related flow, would you try it on RHV-H-4.1.5-RHEL-7.4 ? (In reply to Dan Kenigsberg from comment #31) > Since this showed up in a HostedEngine-related flow, would you try it on > RHV-H-4.1.5-RHEL-7.4 ? I may try this as soon as we'll get 4.1.5 NGN available for testing. 4.1.5 NGN was delivered yesterday, so it should be possible to test now. *** Bug 1478453 has been marked as a duplicate of this bug. *** 1 Tested on latest rhvh-4.1-0.20170815.0+1 with NetworkManager-1.8.0-9.el7.x86_64 on latest downstream 4.1.5 with rhvm-appliance-4.1.20170811.0-1.el7.noarch.

Yes it is, but it should be verified by its QA assignee, once its status changes to ON_QA. This bugzilla is included in oVirt 4.2.0 release, published on Dec 20th 2017. Since the problem described in this bug report should be resolved in oVirt 4.2.0 release, published on Dec 20th 2017, it has been closed with a resolution of CURRENT RELEASE. If the solution does not work for you, please open a new bug report. This now happened to me again, on latest 4.3, I think (I don't have engine logs anymore, only host): Nov 18 12:00:46 vm-10-174 NetworkManager[735]: <info> [1605693646.8934] manager: NetworkManager state is now DISCONNECTED Nov 18 12:00:46 vm-10-174 NetworkManager[735]: <info> [1605693646.8937] policy: set-hostname: set hostname to 'localhost.localdomain' (no default device) Is this a regression? Should I open a new bug? I didn't fully read all the discussion in current bug or in bug 1422610, so didn't understand what was the fix and whether it's applicable now (when in 4.3, IIUC, NM does manage all devices). I think it deserves a new BZ with ref to this one. It may be a regression or a new one with the same results. |
