• ploops over NFS are not supported. (PSBM-20108)
  • In-place upgrading from Virtuozzo 6 to Virtuozzo 7 is not available. (PSBM-29221)
  • Migration of Virtuozzo 6 VMs to Virtuozzo 7 is not supported for Ubuntu and Debian guests. (PSBM-31022)
  • Linux virtual machines with EFI firmware cannot be migrated to Virtuozzo 7. (PSBM-32920)
  • Virtuozzo Image Catalog is not available. (PSBM-39127)
  • Hybrid clusters made of mixed Virtuozzo 6 and Virtuozzo 7 servers are not supported. (PSBM-40861)
  • Attaching backups as block devices to VMs and containers is not supported. (PSBM-40870)
  • In Windows VMs, each new SCSI HDD may be added as offline. As a workaround, you can either bring each disk back online manually. Alternatively, before the first boot with a new disk, run san policy=onlineall in DISKPART to set the SAN policy to OnlineAll. (PSBM-41663)
  • Virtuozzo Automator and Power Panel are not supported (PSBM-41740)
  • Restoring VMs from Virtuozzo 6 backups is not supported. (PSBM-45736)
  • Migration of VMs on NFS or Virtuozzo Storage is not supported. (PSBM-46623, PSBM-40856)
  • Migration of containers with NFS client inside is not supported. (PSBM-47068)
  • Windows-based VMs could freeze on Virtuozzo Storage after multiple cluster failures. The workaround is to remove USB devices from problematic VMs.(PSBM-47925)
  • Secondary SCSI disks can be offline after v2v migration from Virtuozzo 6 to Virtuozzo 7. As a workaround, each disk can be brought back online manually. Alternatively, before the first boot with a new disk, run san policy=onlineall in DISKPART to set the SAN policy to OnlineAll. (PSBM-48700)
  • Secondary disks of containers restored from Virtuozzo 7 backups may contain stale data. (PSBM-49091)
  • Direct and offset autofs mounts served by automount are in inactive state after container migration. To work around the issue, kill the automount process with SIGKILL signal and restart the automount daemon. (PSBM-49104)
  • VMs with Ubuntu 14.04 guests may hang on backup. (PSBM-49106)
  • Changes to boot order are only applied after a complete VM shutdown. (PSBM-49119)
  • Migration of containers with secondary disks between Virtuozzo 7 servers is not supported. (PSBM-49179)
  • Limited simfs support (feature provided as is). (OVZ-6613) Unlike OpenVZ, the simfs layout is based on bindmounts in Virtuozzo 7. When a simfs-based container is started, its private area is bindmounted to the root container area. To create a simfs container: 1) Set VEFSTYPE=simfs in /etc/vz/vz.conf, 2) Run vzctl create <CT_name>. The simfs limitations in Virtuozzo 7 are: 1) No support for first- or second-level quotas, 2) No support for online migration of simfs-based containers.
  • Private networks are not supported.
  • Basic firewall is not supported.
