Review request for cloudstack and edison su. Bugs: CLOUDSTACK-4405 Repository: cloudstack-git Description ------- There still exist two issues after Edison's commits. (1) Migration from new hosts to old hosts failed. The bridge name on old host is set to cloudVirBr* if network.bridge.name.schema is set to 3.0 in /etc/cloudstack/agent/agent.properties, but the actual bridge name is breth*-* after running cloudstack-agent-upgrade. (2) all ports of vms (Basic zone, or Advanced zone with security groups) on old hosts are open, because the iptables rules are binding to device (bridge) name which is changed by cloudstack-agent-upgrade. Diffs ----- agent/bindir/cloudstack-agent-upgrade.in 4972d39 plugins/hypervisors/kvm/src/com/cloud/hypervisor/kvm/resource/BridgeVifDriver.java e3779a7 scripts/vm/network/security_group.py 0ac8b74 Diff: https://reviews.apache.org/r/13992/diff/ Testing ------- tested ok on my environment. After this, the KVM upgrade steps : a. Install 4.2 cloudstack agent on each kvm host b. Run "cloudstack-agent-upgrade". This script will upgrade all the existing bridge name to new bridge name, and update related firewall rules. c. install a libvirt hook: c1. mkdir /etc/libvirt/hooks c2. cp /usr/share/cloudstack-agent/lib/libvirtqemuhook /etc/libvirt/hooks/qemu c3. chmod +x /etc/libvirt/hooks/qemu c4. service libvirtd restart c5. service cloudstack-agent restart Thanks, Wei Zhou
