Subject [jira] [Created] (CLOUDSTACK-4405) (Upgrade) Migrate failed between existing hosts and new hosts
Date Mon, 19 Aug 2013 17:45:48 GMT
Wei Zhou created CLOUDSTACK-4405:

             Summary: (Upgrade) Migrate failed between existing hosts and new hosts
                 Key: CLOUDSTACK-4405
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
    Affects Versions: 4.1.0, 4.2.0
         Environment: CS 4.1
            Reporter: Wei Zhou
            Assignee: Wei Zhou
            Priority: Blocker
             Fix For: 4.1.1, 4.2.0

There are two hosts (cs-kvm001, cs-kvm002) in old 2.2.14 environment .
After upgrade from 2.2.14 to 4.1, I added two new hosts (cs-kvm003, cs-kvm004).

The migration between cs-kvm001 and cs-kvm002, or cs-kvm003 and cs-kvm004 succeed.
However, the migration from cs-kvm001/002 to the new hosts (cs-kvm003, cs-kvm004) failed.

Set name-type for VLAN subsystem. Should be visible in /proc/net/vlan/config

This is because the bridge name on old hosts are cloudVirBr110, and brem1-110 on new hosts.
