  • Virtuozzo hypervisor

Symptoms

Migration hangs on establishing connection and does not prompt for password:

[root@node ~]# vzmigrate root@node.tld 100500
1415796622: ssh -T -q -c arcfour -o StrictHostKeyChecking=no -o CheckHostIP=no -o UserKnownHostsFile=/dev/null -o PreferredAuthentications=publickey,password,keyboard-interactive root@node.tld true

Cause

vzmigrate hangs on password query with openssh-clients from CentOS 6.6 installed on hardware node. This issue recognized as a product bug with internal ID PCLIN-32500

Resolution

Install pending updates on virtualization node.

The issue is fixed permanently since Virtuozzo TU-4.7.0-475 and PSBM TU-5.0.0-1356.

As a workaround it is possible to use authorization by SSH keys between nodes (distribute SSH keys between source and destination servers).
