Known Issues

  • In order for the GPU device to be assigned to a different VM, the persistence mode should be disabled. For more information, please refer to the section "Disable NVIDIA GPU Persistence mode" in the following document: Disable NVIDIA GPU Persistence mode
  • Occasional connection issues to PV guest console. Suggested mitigation solution is to reboot the VM.
  • The automated installation of PV drivers for MS Windows ISO images is not currently supported. An end-to-end functional solution is currently in the development process.
  • Editing an existing VLAN network is not currently supported. In order to edit the VLAN, you must delete and recreate the network.
  • It is not possible to edit the network configuration of a VM in the case the instance boots from an CD/ISO.
  • For a VM instance that is booted from CD/ISO, Sunlight does not initialize the cloud init logic. Network configuration must be applied on the VM by the user.
  • The maximum supported virtual disk size which is currently tested in the system is up to 2TB. Larger size vdisk deployments are currently under test.
  • NexCenter simultaneous resizing of multiple VM instances is not currently supported.
  • During the upgrade phase, primary and secondary nodes will be required to be booted down. Currently, the upgrade is performed manually by the Sunlight support team.
  • It is recommended that the maximum number of instances created in a cluster (all at once) should be limited to less or equal than 8.
  • Please use “SHIFT”, instead of the “CAPS LOCK” button, for capital letters, when typing the login/password of an instance through the VNC console. Using the “CAPS LOCK” button currently results in misspelled username/password.
  • Instances that will be moved and/or backed up in the NexCenter dashboard should have only one root disk. The existence of extra disks is currently not supported in this case.
  • The "Create snapshot" action currently does not support massive parallelism. We are currently testing to lift the limitations.
  • There is a caveat in using all physical NICs on an AWS cluster. Physical NICs 0,2,3 should be used only for private networks. Physical NIC 1 should not be used at all. The rest of the physical NICs, 4 to 15 should be used only for public access networks. In future releases this will be handled automatically via the virtupian UI.
  • Currently we do not support VMs using the UEFI bootloader.
  • We have noticed an issue when using large NVMe drives, larger than 2TB, during the installation process. We suggest that the NVMes are completely zeroe'd out before starting the installation.

PV images

PV images are deprecated - Our suggestion is to use a new template repo that does not include PV images, Please use HVM.

Supported Versions

You can visit the Release notes of the previous versions in the archive section. Please be reminded, versions prior to 4.6.4 are not supported.

We are limiting the scope of the minimum supported version to 4.6.4.

Relevant upgrade procedures will be published, please issue a request with out support team.
