Parallels Cloud Server 6.0 Update 6 Hotfix 3
Parallels has announced a new Hotfix package being made available for Parallels Cloud Server 6.0 -- Update 6 Hotfix 3 provide fixes for virtual machines, Containers, and Parallels Cloud Storage management tools as well as a new kernel based on the Red Hat Enterprise Linux 6.5 kernel (2.6.32-431.17.1.el6). The updated kernel includes a number of security, performance, and stability fixes.
Fixes include:
  • Various kernel panics caused by stack overflow could be triggered by high disk I/O activity (#PSBM-23683, OVZ# 2846).
  • Under certain circumstances, CentOS 6.5 virtual machine could hang (#PSBM-25427).
  • Checkpointing code was enhanced to support ip6tables rules saving and restoring (#PSBM-25872, OVZ# 2916).
  • The "numabalanced" service is designed to move Containers between NUMA nodes in order to increase overall system performance. Previously, such migrations resulted in confusingly huge values of "numastat:node_other" and "numastat:numa_miss" parameters (#PSBM-26309).
  • Network console configured via bonded network interface could cause kernel panic (#PSBM-26668).
  • Under certain circumstances, reinstallation of ploop Containers from Power Panel could not be possible (#PSBM-26738).
  • VNC server could not start after a reboot from inside the Container  (#PSBM-26740).
  • Non-shared migration of Containers with custom private areas kept on Parallels  Cloud Storage (#PSBM-26741).
All Parallels Cloud Server 6.0 users are advised to update their tools packages.
