G'day all, Quick run down of the configuration and architecture I've got;
1 x management server (mgmt) running Centos 6.6 x64, cloudstack management installed, one nic 2 x xenserver 6.2 (xen1 & xen2) no patches installed, 4 nics 1 x nas (nas) sharing primary and secondary nfs, 2 nics On the xenservers, I've created a pool with xen1 being the master, then I've created two network bonds - bond0 for eth0 & 1, bond1 for eth2 & 3 . Management interface has been assigned to bond0. labels are cloud-private bond0 , cloud-public bond1 . At this point, i made no changes to the xe-switch-network-backend, leaving it on vswitch. When adding pool (using xen1 ip address) to cloudstack using the basic setup wizzard, the below error occurs when attempting to add host: Cannot transit agent status with event AgentDisconnected for host 1, mangement server id is 94980626781222,Unable to transition to a new state from Creating via AgentDisconnected After some research, I saw notes on the need to setup bridge mode by using the command xe-switch-network-backend bridge . Also to edit the bridge settings in sysctl.conf by using the following command; sed -i -e '/net.bridge.bridge-nf-call-iptables/ c\net.bridge.bridge-nf-call-iptables = 1' -e '/net.bridge.bridge-nf-call-arptables/ c\net.bridge.bridge-nf-call-arptables = 1' /etc/sysctl.conf After performing this on both my xenserver nodes and rebooting - they no longer have any network connectivity, they can't ping each other nor anything else on the network. It's not until I switch it back to vswitch and reboot that they resume on the network. However this configuration isn't supported by CloudStack. Any thoughts on how I can fix this? Cheers! Chris
