   .. note:: For XenServer version 8.2 to work it might be necessary to manually add a custom storage repository with name "XenServer Tools" containing the systemvm.iso file.

    For any minor versions without hypervisor mappings, all virtual machines have guest OS identifier "otherGuest64" (x86-64 architecture) or "otherGuest" (other architectures).

   .. note:: There is a known issue in 6.7 U1 (https://kb.vmware.com/s/article/67315) which blocks some CloudStack cloning operations. The use of linked clones is known to be effected.

   .. note:: There is a known issue in 6.7 U3 - 6.7 U3f where a mailformed OVA could crash vCenter services (for more information see `here <https://mail-archives.apache.org/mod_mbox/cloudstack-users/202005.mbox/%3CCAMvtBPNQqbe0XEsHyjFMror7HRvj-c%3DfEe7y12NfCDQSFTYgqQ%40mail.gmail.com%3E>`_).
