Folks,
Anybody seen this, is it a known problem?
VM1 on hypervisor 1
----------------------------
ping IP of VM1 on hypervisor2
# ping -c1 192.16.1.5
PING 192.16.1.5 (192.16.1.5) 56(84) bytes of data.
64 bytes from 192.16.1.5: icmp_seq=1 ttl=64 time=0.494 ms
But
# ssh 192.16.1.5
Connection closed by 192.16.1.5 port 22
ssh works between VMs on the same hypervisor, seems going through the
tunnel is the
problem.
