    [ https://issues.apache.org/jira/browse/CLOUDSTACK-3434?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13712880#comment-13712880
] 

Sheng Yang commented on CLOUDSTACK-3434:
----------------------------------------

Seems it's caused by ssh maximum session limitation. Sangeetha could you try to add:

MaxSessions 100
MaxStartups 100

in /etc/ssh/sshd_config to see if the things works?

> Parallel deployment - Xenserver - When deploying 30 Vms in parallel/starting 30 VMs in
parallel, Vms failed because of failing in "SavePasswordCommand"/"Dhcp Entry".
> Steps to reproduce the problem:
> Advanced zone set up with Xenserver host.
> Deploy 30 Vms in parallel.
> Out of 30 vms , 1 vm failed to start successfully and is in "Error" state because of
timing out on the "SavePasswordCommand". 
> Following is the snippet from management server logs:
