The following operating systems are at risk: When attempting to open a console screen from vSphere for the VM:Įrror message: “ The VMRC console has disconnected.attempting to reconnect.” Guest console in vSphere 5 fails to run on some Microsoft platforms Them otherwise hwfail is created and the VM Expressway will not run.įor NTP to work on Expressway, the same NTP must also be configured on the VM host. Look at the /tmp/hwfail file – its content indicates any violations in the installation.įor example, Expressway reserves 3 virtual NICs – these are required in the Expressway, do not try deleting one or more of If it is not set, set it and reinstall ESXi then load the. If the VM image fails to boot, check the VT (Virtualization Technology) setting in BIOS. To the VM Expressway application from the network.Ĭheck any critical alarms on the VM application for events on the host or application level (check the event information from If vCenter is not operating properly, although the VM Expressway application is still up and running, you may lose connection Storage may cause application failures because the application cannot access the file system.ĭNS server failures or communication failures between DNS and the VM server may cause the VMware application or the VM Expressway VCenter Server fails after an indefinite amount of timeĪny network failure or locking causes a connection failure between the VM and the virtual network. VMs often freeze or hang up if theĪpplication failed to access the storage. Look for the VM store application image stored either on the local drive, SAN, or NFS. The vCenter Server database user is not granted correct permissions. The password on the account you are using to authenticate to the database has changed but the password in the registry has There are permission issues with the database when importing from one instance to another. The vCenter Server service may not be able to authenticate with the Validate authentication to the vCenter Server database. Verify that adequate disk space is available on the physical volume that stores the database files. This log contains common error logs such as iSCI naming error, authentication error, and host convertibility error. Or execute the command esxtop from Tech Support Mode to list all system processes running on the ESXi host application.Ĭheck the ESXi server file log ( hostd.logs) under the folder /var/log/vmware. If any specific application causes high utilization, stop or restart this application to isolate the overall VM host performance CPU utilization, memory utilization, disk access speed, storage access speed, networkĪccess status, power utilization, and so on. If you have problems connecting to the vSphere Client management console, execute the command/sbin/services.sh from an SSH session to restart the ESXi management agent.Ĭheck the VM host server utilization. Ĭheck accessibility to the VM host server (by ping, physical console access, SSH remote access, KVM-over-IP console, and soĬheck network connectivity of the VMkernel (by executing the vmkping command using Tech Support Mode to verify network connectivity from the VMkernel NIC level). The VMware compatibility guide tool from. If you use third-party hardware to host the VM Expressway application, check the hardware compatibility.
