Description Don Hoover 2011-06-09 17:21:34 UTC

Description of suggestion:

Right now, the vm.sh only supports using a migration_uri over direct TCP ports between nodes. 

virsh also supports a '--tunneled' option that will perform the migration over SSH instead of requiring firewall ports to be open between the nodes.

Comment 4 Chris Feist 2012-03-05 22:04:15 UTC

Before fix running a vm on ask-03:

OCF_RESKEY_name="test3" OCF_RESKEY_xmlfile=/etc/libvirt/qemu/test3.xml /usr/share/cluster/vm.sh migrate ask-04

tcpdump shows lots of traffic over a random 49xxx port:
15:55:11.220530 IP 10.15.85.4.49162 > 10.15.85.3.35559: Flags [.], ack 143716529, win 24576, options [nop,nop,TS val 263638322 ecr 254144338], length 0




After fix on a vm running on ask-04:
OCF_RESKEY_name="test3" OCF_RESKEY_xmlfile=/etc/libvirt/qemu/test3.xml /usr/share/cluster/vm.sh migrate ask-03


tcpdumps shows traffic over ssh
15:52:00.986503 IP 10.15.85.4.57094 > 10.15.85.3.ssh: Flags [.], seq 98251302:98252750, ack 47102, win 176, options [nop,nop,TS val 263448089 ecr 253954129], length 1448

Don,

Would you be willing to test out a new package built with a fix for this issue?

Thanks,
Chris
