Added hot plugging of vifs in case of VMware isolated networks by harikrishna-patnala · Pull Request #5912 · apache/cloudstack

harikrishna-patnala · 2022-01-31T11:03:25Z

Description

This PR fixes #5716 where isolated network VR failed to deploy when Vmxnet3 adapter type is used and when router.extra.public.nics is not 0. This is because of the extra nics that are reserved in the VR based on the global setting router.extra.public.nics.

To address the issue we have now implemented nic hot plugging for isolated networks because systemvm templates had open-vm-tools installed and support hot plugging which is what is already used in the case of VPC VR.

How Has This Been Tested?

Steps to reproduce:

Set the global setting vmware.systemvm.nic.device.type to Vmxnet3 and router.extra.public.nics to some value (not 0)
Create an isolated network and VM in it.
VR will stuck in starting state

After the fix, following are the test cases that are performed

Set the global setting vmware.systemvm.nic.device.type to Vmxnet3. router.extra.public.nics is not used in VMware anymore.
Create an isolated network N1 and VM in it
Add a new IP range with different vlan under "Physical Network Guest Public".
Aquire an IP from the above range in the network N1
Enable staticnat on that IP
Observed VR interfaces a new interface is created dynamically

Followed the same steps with vmware.systemvm.nic.device.type value E1000 and VR came up and subsequent operations of acquiring IP, enabling static NAT worked fine.

…g router.extra.public.nics in case of VMware. Added hot plugging of vifs whenever required in case of isolated networks. VPC networks already uses hotplugging of vifs.

I have tested many scenarios with isolated networks and vpcs.

all looks ok, except an issue: #5934
I think it is not related to this PR.

did you test that issue in a generic 4.16, @weizhouapache ?

@DaanHoogland
yes, 4.16 does not support both hotplug and hot-unplug.
with this pr, hotplug is supported.
we could merge this at first, then support hot-unplug afterwards.
