Subject [jira] [Commented] (CLOUDSTACK-1164) Use libvirt for security groups for KVM
Date Wed, 08 Feb 2017 14:28:42 GMT


Wido den Hollander commented on CLOUDSTACK-1164:

Not yet implemented. Still very much wanted, but it will require a complete rewrite of the
code on the KVM Agent.

In addition I have no way how to do a clean migration for running VMs when the Agent is upgraded.

>                 URL:
>             Project: CloudStack
>          Issue Type: Wish
>      Security Level: Public(Anyone can view this level - this is the default.) 
>          Components: Hypervisor Controller, KVM
>    Affects Versions: 4.0.0, 4.1.0
>            Reporter: Wido den Hollander
>              Labels: kvm, libvirt, security-groups
>             Fix For: Future
> The current implementation for the security groups uses a custom Python script which
applies iptable and ebtable rules to the hypervisor.
> Libvirt also supports this with network filters:
> It might be cleaner to do this via libvirt, but the downside is that a lot of functions
are only supported by libvirt 0.9.8 and higher.
> This might not be possible at this moment, but it might be worth a shot at a later stadium.
