Hi,

Is it possible yo use keepalived for HA with OpenVZ containers or will it only work with KVM? I see that I cannot set net.ipv4.ip_nonlocal_bind=1 within a container.

I haven't been able to find much info on the net which makes me think that it might be a problem

I have been testing with KVM and this is working, but I would like to use it with OpenVZ containers.

Using ProxMox 3.4 currently.
 
Supp,

I am working on HA network solution and i was thinking of implementing carp or keepalived.
Would you like to share your working configuration?

I thought the linux networking acted funky with multicast needed vor the virtual ip's, and openvswitch is still a no go with multicast.
 
Hi,

What I did was to setup two small KVM instances with Keepalived running in them with HAProxy and then pointed these to my backend web servers running in OpenVZ containers.

Works like a charm.
 
Good to hear this works on proxmox.

I already got my setup working with ucarp, because i needed to give KVM instances a public ip with a shared gateway accross the proxmox nodes. Maybe in the future i will tackle keepalived or plain CARP for balancing.

thnqx for the information.
