Event 5001, xennet6 after installing XenTools

Author : Ingmar Verheij

After installing the XenTools (version 6.0.0.50762) on a Windows Server 2008 R2 virtual machine, hosted on a Citrix XenServer 6.0 (build 50762p), the network connectivity degraded. Although I could connect to the machine via RDP the provisioning server was marked Down and XenDeskop services terminated unexpectedly.

As a workaround you can disable IPv6 on the network connections where you don’t use IPv6. After a reboot you can enable IPv6 again, the xennet6 error will remain but both PVS and XenDesktop worked fine.

If disabling IPv6 doesn’t work you can install XenTools 5.6 SP2, but I would try to keep it as a last resort. More information about the issue can be found on Citrix Forums.
