Symptoms

Migration of virtual machine fails with:

#  prlctl migrate MyVM 192.168.12.12 --dst /pcs/vmprivate
Migrate the VM MyVM on 192.168.12.12 (/pcs/vmprivate)
root@192.168.12.12:

Unable to migrate the virtual machine. The virtual machine or the source and destination servers do not comply with the migration requirements.
Disconnect or remove the device $DEVICE_NAME from the virtual machine configuration and try again.

Cause

VM has more than one emulated (not physical) hard drives and one of them uses symlink /var/parallels->/vz/vmprivate in path:

~# prlctl list MyVM -i -f |egrep 'hdd|Home'
Home: /var/parallels/MyVM.pvm/
Boot order: hdd0 hdd1 net1
  hdd0 (+) sata:0 image='/var/parallels/MyVM.pvm/MyVM_disk_1.hdd' type='expanded' 81920Mb
  hdd1 (+) sata:2 image='/vz/vmprivate/MyVM.pvm/MyVM_disk_2.hdd' type='expanded' 1024000Mb

/var/parallels/ is a symlink to /vz/vmprivate by default:

# ls -l /var/ |grep parallels
lrwxrwxrwx  1 root root    25 Sep 16  2013 parallels -> /vz/vmprivate/

The issue has been recognized as product bug PSBM-24812

Resolution

VMs that uses symlink /var/parallels->/vz/vmprivate in names of device image files can be migrated since PCS 6.0 Update 7 (6.0.7-2195)
