Messages under the vCenter Events windows are displayed every 30 seconds and not every 60 seconds. 1 August 31, 2021 Original Document Release. After updating VMware ESXi 7.0 to VMware ESXi 7.0.1 on any HPE Gen9 / Gen10 / Gen10 Plus platform using the HPE custom images beginning in January 2021, multiple messages are continuously logged on the host. When using the vSphere Web Client and logged into vCenter, entries similar to the following may be displayed every 30 seconds under the vCenter Events window: User root@127.0.0.1 logged out (login time: Friday, May 21, 2021 8:09:04 AM UTC, number of API invocations: 7, user agent: pyvmomi Python/3.5.9 (VMkernel; 7.0.1; x86_64)) In addition, entries similar to the following may be logged in the following log files: /var/log/syslog.log root: vusb: root: VIRTUAL NIC:****NO VUSB0 AVAILABLE root: Call wait loop root: Virtual NIC: in wait loop /var/log/hostd.log info hostd[2101028] [Originator@6876 sub=Vimsvc.TaskManager opID=esxcli-39-7234 user=root] Task Created : haTask--vim.EsxCLI.network.nic.list-1269523045 info hostd[2100413] [Originator@6876 sub=Vimsvc.TaskManager opID=esxcli-39-7237 user=root] Task Created : haTask--vim.SessionManager.logout-1269523047 This issue occurs because the vnicen.sh script implemented in VMware ESXi 7.0.1 continuously checks for the vNIC but logs a message when the check fails when it is executed on a system with virtual NIC support (Gen10, Gen10 plus) where it has not been enabled, or a system without virtual NIC support (Gen9).
Any HPE Gen9 / Gen10 / Gen10 Plus platform upgraded to VMware ESXi 7.0.1 using HPE custom images starting in January 2021.
To resolve this issue, download and install the HPE ESXi Custom image "7.0 U3 Oct 26 2021 vSphere 7.0 U3 Build 18644231" available at the following URL: VMWARE ESXI IMAGE FOR HPE SERVERS Workaround For platforms that cannot perform the resolution above, execute the following commands from the VMware ESXi host shell command line to stop the vnicen.sh script from looping: To identify the PID for the vnicen.sh script ps -c | grep vnic Example ps -c |grep vnic 527045 527045 sh /bin/sh /etc/init.d/vnicen.sh start 529575 529575 grep grep vnic Use PID of the vnicen.sh to stop the vnicen.sh script Kill [PID of vnicen.sh] Example kill 527045 To ensure that the vnicen.sh script does not restart after a reboot chkconfig vnicen.sh off To confirm this setting chkconfig --list | grep vnicen vnicen.sh off A reboot of the VMware ESXi host is required, so the changes can take effect into the configuration.
