What to look for
Network
Any network failure or locking causes a connection failure between the VM and the virtual network.
Also, if using NFS or iSCSI, storage may cause application failures because the application cannot
access the file system.

DNS
DNS server failures or communication failures between DNS and the VM server may cause the
VMware application or the VM Expressway application to fail.

If vCenter is not operating properly, even though the VM Expressway application is still up and
running, you may lose connection to the VM Expressway application from the network.

Possible issues
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.
enabled for hosting VMs. If it is not set, set it and re-install ESXi then load the .ova file.
Expressway application fails to start
Look at the /tmp/hwfail file – its content will indicate any violations in the installation.
For example, Expressway reserves 3 virtual NICs – these are required in the Expressway, do not try deleting
one or more of them otherwise hwfail will be created and the VM Expressway will not run.
one or more of them otherwise hwfail will be created and the VM Expressway will not run.
Configured NTP does not work
For NTP to work on Expressway, 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:
n
Error message: “The VMRC console has disconnected...attempting to reconnect.”
n
Screen remains black
The following operating systems are at risk:
n
Windows 7 64 bit – reported on VMware forum (
)
n
Windows Server 2008 R2 (64-bit) – found by use
Raid controller synchronization
If the VMware system is synchronizing its RAID disks, disk performance is seriously degraded. It is strongly
recommended that Expressway is not installed or run on VM platforms where RAID disks are in a degraded
or synchronizing state.
