harvester [BUG] VM only shows the IPV6 address when infoSource is more than one

[BUG] VM only shows the IPV6 address when infoSource is more than one

Open W0n9 opened this issue 9 months ago • 26 comments

Describe the bug

When the VM has been assigned with both IPV4 and IPV6 addresses, the VMI will only store the IPV6 address, even which IPV6 address is not assign by the VM.

The IPV6 address in VMI is seemingly assigned by SLAAC, but doesn't use by the VM. The VM uses the Static IP config with cloud-init network-data. And when I try to stop the qemu-guest-agent.service with sudo systemctl stop qemu-guest-agent, the VMI status change with below:

status:
  guestOSInfo: {}
  interfaces:
    - infoSource: domain, multus-status
      ipAddress: 2001:250:207:df:4c49:b2ff:fec6:be9f
      ipAddresses:
        - 2001:250:207:df:4c49:b2ff:fec6:be9f
      mac: 4e:49:b2:c6:be:9f
      name: default
      queueCount: 1
  launcherContainerImageVersion: registry.suse.com/suse/sles/15.5/virt-launcher:1.1.1-150500.8.15.1

To Reproduce Steps to reproduce the behavior:

create a VM with cloud-init, both user-data and network-data.
set the first network to use VLAN network.
create the VM and wait for it to be ready.

Expected behavior

Store both IPv4 and IPv6 addresses, and it is consistent with the ip addr command in the VM.
