New ESXi patch, build 236512
Posted by VMax on March 10, 2010 | No comments
VMware released another patch for their ESXi 4.0 systems. The 180MB patch contains a firmware and VMware Tools update. You can download the patch at the VMware support site, KB 1018404. Installing the patch is a breeze following my guide. Following issues are resolved:
- On some systems under heavy networking and processor load (large number of virtual machines), some NIC drivers might randomly attempt to reset the device and fail.
The VMkernel logs generate the following messages every second:
Oct 13 05:19:19 vmkernel: 0:09:22:33.216 cpu2:4390)WARNING: LinNet: netdev_watchdog: NETDEV WATCHDOG: vmnic1: transmit timed out
Oct 13 05:19:20 vmkernel: 0:09:22:34.218 cpu8:4395)WARNING: LinNet: netdev_watchdog: NETDEV WATCHDOG: vmnic1: transmit timed out
- ESXi hosts do not display the proper status of the NFS datastore after recovering from a connectivity loss.
Symptom: In vCenter Server, the NFS datastore is displayed as inactive.
- When using NPIV, if the LUN on the physical HBA path is not same as the LUN on the virtual port (VPORT) path, though the LUNID:TARGETID pairs are same, then I/O might be directed to the wrong LUN causing a possible data corruption. Refer KB 1015290 at for more information.
Symptom: If NPIV is not configured properly, I/O might be directed to the wrong disk.
- On Fujitsu systems, the OEM-IPMI-Command-Handler that lists the available OEM IPMI commands do not work as intended. No custom OEM IPMI commands are listed, though they were initialized correctly by the OEM. After applying this fix, running the VMware_IPMIOEMExtensionService and VMware_IPMIOEMExtensionServiceImpl objects display the supported commands as listed in the command files.
- Fixes an issue where some applications do not receive events even after registering for Asynchronous Event Notifications (AEN). This issue occurs when multiple applications register for AENs.
- In scenarios where Pass Thru Switching (PTS) is in effect, if virtual machines are powered on, the network interface might not come up. In PTS mode, when the network interface is brought up, PTS figures the MTU from the network. There is a race in this scenario, where the enic driver might incorrectly indicate that the driver fails. This issue might occur frequently on a CISCO UCS system.
- Provides a change to the maintenance mode requirement during Cisco Nexus 1000V software upgrade. After installing this patch if you perform Cisco Nexus 1000V software upgrade, the ESX host goes into maintenance mode during the VEM upgrade.
- In certain race conditions, freeing journal blocks from VMFS filesystems might fail. The WARNING: J3: 1625: Error freeing journal block (returned 0) <FB 428659> for 497dd872-042e6e6b-942e-00215a4f87bb: Lock was not free error is written to the VMware logs.
- Changing the resolution of the guest operating system over a PCoIP connection (desktops managed by View 4.0) might cause the virtual machine to stop responding.
Symptoms: The following symptoms might be visible:
- When you try to connect to the virtual machine through a vCenter Server console, a black screen appears with the Unable to connect to MKS: vmx connection handshake failed for vmfs {VM Path} message.
- Performance graphs for CPU and memory usage in vCenter Server drop to 0.
- Virtual machines cannot be powered off or restarted.
- Provides prebuilt kernel module drivers for Ubuntu 9.10 guest operating systems.
- Adds support for upstreamed kernel PVSCSI and vmxnet3 modules.
