New subject: Fw: Network issues with oVirt 4.2 and cloud-init

Tuesday, 20 March 2018

Hi Sandy,

Can you elaborate some more about the steps you have taken?

Specifically, how\where do you apply cloud-init-0.7.9-20 rpm? Can you make
sure that rpm -q cloud-init after VM reboot is still this one?

How do you apply the static IP settings that do persist to the VM - via
oVirt web-admin\REST API\other?

When you restart the VM via oVirt GUI - do you 'Run' it or 'Run Once'?

Thanks,
Eitan

 We're using cloud-init to customize VMs built from a template. We're
 using static IPV4 settings so we're specifying an IP address, subnet
 mask, and gateway. There is apparently a bug in the current version of
 cloud-init shipping as part of CentOS 7.4
 (https://bugzilla.redhat.com/show_bug.cgi?id=1492726) that fails to set
 the gateway properly. In the description of the bug, it says it is
 fixed in RHEL 7.5 but also says one can use
 https://people.redhat.com/rmccabe/cloud-init/cloud-init-
 0.7.9-20.el7.x86_64.rpm
 which is what we're doing.

 When the new VM first boots, the 3 IPv4 settings are all set correctly.
 Reboots of the VM maintain the settings properly. But, if the VM is
 shut down and started again via the oVirt GUI, all of the IPV4 settings
 on the eth0 virtual NIC are lost and
 the /etc/sysconfig/network-scripts/ifcfg-eth0 shows that the NIC is now
 set up for DHCP.

 Are we doing something incorrectly?
