New VMware ESXi 5.0 Patch Released

A few days ago VMware released a new patch bundle for ESXi 5.0. The new build number is 821926. You can find the full details here. As always, you can download the patches from their download portal here. The fixes are of severity “Important” and require VM shutdown and Host reboot.

Fixed in this release is:

  • PR667599: Certain vSphere Client initiated storage operations such as Storage Rescan, Add Storage, or Detach LUN might take a long time to complete or fail due to a timeout when ESXi host has access to VMFS snapshot volumes (replica LUNs). This patch addresses the issue by reducing the time taken to complete these operations.

  • PR787454: After performing vMotion operations on virtual machines, a NUMA imbalance might occur with all the virtual machines being assigned the same home node on the destination server.
 
  • PR817140: On IBM BladeCenter HX5 UEFI servers, a message similar to the following might be displayed in the vSphere Client when you attempt to configure the power policy of an ESXi host:
Technology: Not Available
Active Policy: Not Supported.
  • PR886363: When a virtual machine is cloned through vCenter Server, the VM Generation ID of the cloned Windows 8 and Windows Server 2012 virtual machines is not updated.
 
Note:To resolve this issue, you can edit the .vmx file of the cloned virtual machine to set the vm.genid to 0 or remove the line vm.genid from the .vmx file.
 
 
  • PR887134: Timer stops in FreeBSD 8.x and 9.x as virtual hardware HPET main counter register fails to update due to comparison failure between signed and unsigned integer values.
 
 
  • PR896193: The VMGencounter generation ID is increased to 128-bit value to support specification changes from MSFT and also ACPI notification support is added.
  • PR903619: The timers resulting from I/O operations are allocated from VMKernel main heap. With increased I/O activity, the number of timers increase proportionally leading to depletion of main heap and eventually resulting in a purple diagnostic screen.
  • PR908776: A virtual machine might fail when it encounters error conditions during snapshot operations. Messages similar to the following are logged in the vmware.log file:

  • R881444: Large number of UDP packets are dropped when you use the VMXNET3 adapter in a Linux guest OS on an ESXi 5.0 host.

  • PR901683: After creating Microsoft Windows Server 2012 (64-bit) virtual machines with the create VM UI wizard and then installing VMware Tools, the guest OS name changes from Microsoft Windows Server 2012 (64-bit) to Microsoft Windows 8 (64-bit).
 
  • This patch updates the misc-drivers VIB to resolve an issue where the ESXi hosts might encounter a purple diagnostic screen with one of the following messages due to a deadlock during SCSI command completion:

  • This patch updates the esx-base VIB to resolve an issue that occurs when you enable BPDU (Bridge Protocol Data Unit) guard on the physical switch port. The BPDU frames sent from the bridged virtual NIC cause the physical uplink to get disabled and as a result, the uplink goes down.
