Murali Reddy commented on CLOUDSTACK-6755: ------------------------------------------ Test case does not exist for testing this scenario. > [OVS] Can't create more than 7 GRE tunnel networks in xen cluster > ----------------------------------------------------------------- > > Key: CLOUDSTACK-6755 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6755 > Project: CloudStack > Issue Type: Bug > Security Level: Public(Anyone can view this level - this is the > default.) > Components: Management Server, Network Controller, XenServer > Affects Versions: 4.4.0 > Environment: Latest build from 4.4 with commit > e6961fd21bb6d793302c234d0f409f66dc498072 > Reporter: Sanjeev N > Assignee: Murali Reddy > Priority: Blocker > Labels: DEV_REVIEWED, ovs > Fix For: 4.4.0 > > Attachments: management-server.rar, ovstunnel.log, xensource.log > > > [OVS] Can't create more than 7 GRE tunnel networks in xen cluster > Steps to reproduce: > ================== > 1.Bring up CS in advanced zone with Xen cluster > 2.Create physical network with GRE isolation > 3.Create isolated network offering with virtual networking and OVS as the > service provider > 4.Create 8 guest networks with above offering and deploy vms in each network > Result: > ====== > CS would create 7 networks successfully and deploying vm in 8th network would > fail because Tunnel network creation would fail for 8th network > Following is the log snippet from MS log: > 2014-05-23 10:18:12,784 DEBUG [c.c.n.e.OvsElement] > (Work-Job-Executor-89:job-253/job-254 ctx-800616c3) Checking if OvsElement > can handle
