Hi.
We need several interfaces basically cause we are using separate
networks for admin, public access from users and private access
to backend servers. With this configuratino we need THREE
interfaces.
And if we want to loabalance several applications with the same
ZENLB instance...we need TWO additional interfaces (1 for
clients public access and 1 for backend access) per application.
Regards.

Hi Jose
Why would you assign so many NIC's to the virtual machine -
or was this some sort of capacity/stress test? We have run
successfully with just one NIC for 18 months (right from the
beginning). I understand the use of 2, possibly even 3 if you
had a dedicated management vSwitch.
Is the issue the underlying Linux build?
Thanks

Hi.
I've installed ZENLB in a vmware virtual machine.
As I'm using this to do some testings it has multiple network
interfaces.
I've observed that if the number of network interfaces is 6-7
or greater, the behavior of the interfaces is "strange" (i.e:
everything appears to be ok in ZENLB but they are no
connectivity in some interfaces).
* deleting some interfaces in the ZENLB virtual machine cause
everything to run OK again.
They are some limitation in the number of interfaces that
ZENLB can manage?
Some additional info:
- I'm using the latest community version of ZENLB (v3.0.2)
- I've defined the interfaces as VMXNET3 type
- The vmware limit on maximum number network interfaces per VM
(10 in vsphere 5) is not reached
- The VM is defined with 1 vCPU and 1GB RAM memory
Regards.
