Known Issues

The following known issues affect version 104 of the "Citrix: Xen" PowerPack:

  • There is a known issue in XenCenter that may cause a mismatch in the control domain size with the Windows UI if it has been recently changed. The value in SL1 is the correct the domain size. You can double check the correct value by using PuTTY or a similar application to SSH into the Xen server and running the following command:

    ./opt/xensource/libexec/xen-cmdline --get-xen dom0_mem

    NOTE: SL1 may round this value slightly.
  • There is a known issue that is causing a discrepancy between the units of measurement for metrics that are collected by some performance Dynamic Applications and the graphs that display those metrics.
