Hi I am hoping someone could help with a new Dev Cloudstack system we are trying to setup based on Ubuntu 20.04 KVM hosts and mgmt. servers with CS 4.15.2 and an Adv Zone with VPC's
We spotted that the RVR's in the VPC's are both in the 'MASTER' state indicating that they cannot communicate with each other. Also testing within a guest VM - it is able to ping another guest VM in the same network - but only when on the same KVM host. If we live migrate one of the VM's to a different KVM host then the ping breaks. Our guest network is using VXLAN isolation method and all network labesl in CS are correct. We are trying to setup this Dev system to match our production system as closely as possible and all networking works perfectly in the Production system One thing we have noticed is if we put a KVM host into maintenance mode - thus destroying all the brvx-xxx interfaces on there and then bring it back out of maintenance mode and migrate VM's to it and Restart the VPC with cleanup enabled - communication between VM's cross host works again for a few minutes. The RVR's go into Master and Backup status briefly - but then after a few minutes both VR's go into 'MASTER' state and VM's cannot ping each other when on different hosts. Any pointers/help would be greatly appreciated BR Gary Gary Dixon Senior Technical Consultant T: +44 161 537 4990 E: v...@quadris-support.com W: www.quadris.co.uk The information contained in this e-mail from Quadris may be confidential and privileged for the private use of the named recipient.
