Possible Issues
Medium OVA fails to install on UCS host with 2 * 2.4 GHz CPU
Prior to X8.7.1, the OVA file CPU reservation requirement was strictly enforced at 4800 MHz. Natural variations in
hardware means that some UCS tested reference configurations with 2 * 2.4 GHz cores were not providing exactly
4800 MHz, and the OVA would not install.

We recommend installing an X8.7.1 (or later) OVA if you encounter this issue with an earlier version.
VM image fails to boot
If the VM image fails to boot, check the VT (Virtualization Technology) setting in BIOS. This needs to be enabled for
hosting VMs. If it is not set, set it and re-install ESXi then load the .ova file.
hosting VMs. If it is not set, set it and re-install ESXi then load the .ova file.
VCS application fails to start
Look at the /tmp/hwfail file – its content will indicate any violations in the installation.
For example, VCS reserves 3 virtual NICs – these are required in the VCS, do not try deleting one or more of them
otherwise hwfail will be created and the VM VCS will not run.
otherwise hwfail will be created and the VM VCS will not run.
Configured NTP does not work
For NTP to work on VCS, the same NTP must also be configured on the VM host.
Guest console in vSphere 5 fails to run on some Microsoft platforms
When attempting to open a console screen from vSphere for the VM:
■
Error message: “The VMRC console has disconnected...attempting to reconnect.”
■
Screen remains black
The following operating systems are at risk:
■
Windows 7 64 bit – reported on VMware forum (
)
■
Windows Server 2008 R2 (64-bit) – found by use
Web page/IP address unreachable after OVA deployment
This issue can be caused by a cache issue in the gateway switch.
To resolve, access vCenter, go to the console and ping the gateway:
ping
<gateway_ip_address>.
Web page unreachable while taking snapshot
When taking a snapshot, the entire state of the virtual machine is stunned (paused) so snapshot files can be written
to disk.
to disk.
To resolve, shut down the VM before taking snapshots.
Clustering status incorrect after recreating a VM within a cluster
When recreating a VM within a cluster, the cluster must be broken and recreated for it to function correctly.
