VMware View 5.0 VDI vHardware 8 vMotion Error

General awareness/heads up blog post here on something I stumbled on with VMware View 5.0.  A few weeks ago while working with View 5.0 BETA in the lab, I ran into an issue where a Windows 7 virtual machine would not vMotion from one ESXi 5.0 host to another.  The resulting error in the vSphere Client was:

A general system error occurred: Failed to flush checkpoint data

I did a little searching and found similar symptoms in VMware KB 1011971 which speaks to an issue that can arise  when Video RAM (VRAM) is greater than 30MB for a virtual machine. In my case it was greater than 30MB but I could not adjust it due to the fact that it was being managed by the View Connection Server.  At the same time, a VMware source on Twitter volunteered his assistance and quickly came up with some inside information on the issue.  He had me try adding the following line to /etc/vmware/config on the ESXi 5.0 hosts (no reboot required):

migrate.baseCptCacheSize = “16777216″

The fix worked and I was able to vMotion the Windows 7 VM back and forth between hosts.  The information was taken back to Engineering for a KB to be released.  That KB is now available: VMware KB 2005741 vMotion of a virtual machine fails with the error: A general system error occurred: Failed to flush checkpoint data! The new KB article lists the following background information and several workarounds:

Cause

Due to new features with Hardware Version 8 for the WDDM driver, the vMotion display graphics memory requirement has increased. The default pre-allocated buffer may be too small for certain virtual machines with higher resolutions. The buffer size is not automatically increased to account for the requirements of those new features if mks.enable3d is set to FALSE (the default).

Resolution

To work around this issue, perform one of these options:

  • Change the resolution to a single screen of 1280×1024 or smaller before the vMotion.
  • Do not upgrade to Virtual Machine Hardware version 8.
  • Increase the base checkpoint cache size. Doubling it from its default 8MB to 16MB (16777216 byte) should be enough for every single display resolution. If you are using two displays at 1600×1200 each, increase the setting to 20MB (20971520 byte).To increase thebase checkpoint cache size:
    1. Power off the virtual machine.
    2. Click the virtual machine in the Inventory.
    3. On the Summary tab for that virtual machine, click Edit Settings.
    4. In the virtual machine Properties dialog box, click the Options tab.
    5. Under Advanced, select General and click Configuration Parameters.
    6. Click Add Row.
    7. In the new row, add migrate. baseCptCacheSize to the name column and add 16777216 to the value column.
    8. Click OK to save the change.

    Note: If you don’t want to power off your virtual machine to change the resolution, you can also add the parameter to the /etc/vmware/config file on the target host. This adds the option to every VMX process that is spawning on this host, which happens when vMotion is starting a virtual machine on the server.

  • Set mks.enable3d = TRUE for the virtual machine:
    1. Power off the virtual machine.
    2. Click the virtual machine in the Inventory.
    3. On the Summary tab for that virtual machine, click Edit Settings.
    4. In the virtual machine Properties dialog box, click the Options tab.
    5. Under Advanced, select General and click Configuration Parameters.
    6. Click Add Row.
    7. In the new row, add mks.enable3d to the name column and add True to the value column.
    8. Click OK to save the change.

Caution: This workaround increases the overhead memory reservation by 256MB. As such, it may have a negative impact on HA Clusters with strict Admission Control. However, this memory is only used if the 3d application is active. If, for example, Aero Basic and not Aero Glass is used as a window theme, most of the reservation is not used and the memory could be kept available for the ESX host. The reservation still affects HA Admission Control if large multi-monitor setups are used for the virtual machine and if the CPU is older than a Nehalem processor and does not have the SSE 4.1 instruction set. In this case, using 3d is not recommended. The maximum recommended resolution for using 3d, regardless of CPU type and SSE 4.1 support, is 1920×1200 with dual screens.

The permanent fix for this issue did not make it into the recent View 5.0 GA release but I expect it will be included in a future release or patch.”

 

I quoted the whole blog, as I thought it was a great post, Thanks Jason!

Below is the Press release

 

“ROUND ROCK, Texas, August 22, 2011 – Dell today announced new Dell EqualLogic storage solutions and supporting software to help customers address the data management requirements of increasingly dynamic, virtualized data centers. The company also released details of new integration across its storage portfolio with the forthcoming VMware vSphere® 5 virtualization and cloud infrastructure platform.

Today’s announcements represent another milestone in the continued evolution of Dell Fluid Data solutions, designed to help customers more effectively manage valuable business information in virtualized data centers.

New Dell EqualLogic Storage Platform Extends Fluid Data Architecture

In support of customers’ growing storage demands, Dell introduced the EqualLogic PS6100 and PS4100 family of virtualized, IP-based storage offerings. Together with new Dell EqualLogic firmware version 5.1, Dell offers customers its next generation of EqualLogic storage solutions that seamlessly integrate into existing environments without downtime or a major overhaul, enabling customers to focus on managing their storage and not the manual process of upgrading infrastructure.

This launch marks the introduction of 2.5-inch drive support for the EqualLogic product line, providing greater density and enabling IT managers to purchase only the storage they want and to scale as needed. Customers can gain up to 60 percent performance improvement on typical workloads with the EqualLogic PS Series compared to previous generation EqualLogic arrays. 1

EqualLogic PS Series arrays, regardless of generation, work together to automatically manage data, load balance across all resources, and expand to meet growing storage needs. Dell provides these capabilities without requiring customers to “rip and replace” their storage environment during each upgrade cycle as they would with other vendors.  New storage arrays include: 

· EqualLogic PS4100 Series — ideal for small-to-medium businesses or remote office locations with growing storage needs. The SANs support up to 36TB in a single array and can scale as storage demands increase by seamlessly adding additional PS4100 or PS6100 arrays into an EqualLogic group.

· EqualLogic PS6100 Series — designed to provide mid-sized customers with a scalable storage environment, up to 72TB in a single array and 1.2PB in a single group, that can easily accommodate both high-performance and high-capacity drive options. The PS6100 family is ideal for customers looking for an IP-based storage solution to support the storage demands of a highly virtualized data center environment where the seamless movement and protection of virtual machines, applications and data is crucial.

With the newly redesigned, compact form factor, PS6100 customers can achieve the same performance for their typical workload using half the number of arrays, and receive 50 percent more expansion capacity when compared with previous generation EqualLogic arrays.2

This month, Dell also has begun shipping the new EqualLogic FS7500, the company’s latest NAS solution that works with EqualLogic PS Series arrays to deliver the only scale-out, unified storage platform for mid-size deployments. The FS7500 uses the Dell Scalable File System, which offers several advanced features including cache monitoring, load balancing and multi-threading for fast I/O processing.

Dell and VMware Partner for Industry-Leading Integrated Solutions

Dell and VMware have expanded their strategic partnership over the past decade, collaborating on engineering integration and solutions development since server virtualization first emerged. As customers’ virtual environments have grown, Dell and VMware have worked together to develop specifications for storage infrastructures, such as the VMware vSphere® Storage APIs for Array Integration, and have delivered highly virtualized data center and storage solutions to meet joint customer needs. 

For example, the latest EqualLogic firmware version 5.1 includes thin provisioning awareness for VMware vSphere to help users save valuable recovery time and help mitigate the risk of potential data loss. Dell is one of VMware’s largest global resellers , helping enable the company to uniquely address customers’ virtualized storage needs.

With the recent announcement of forthcoming VMware vSphere 5, Dell today introduced a new set of VMware specific enhancements for Dell EqualLogic, Dell Compellent and Dell PowerVault storage customers. These enhancements will roll-out through Q3 and Q4 and include:

· Dell EqualLogic Host Integration Tools for VMware 3.1 — provide customers with enhanced storage visibility and datastore management as well as improved performance and availability through tight integration with VMware vSphere 5, VMware vSphere Storage APIs for Storage Awareness,  VMware Storage Distributed Resource Scheduler (SDRS), and VMware vCenter™ Site Recovery Manager 5.

· Dell Compellent Storage Replication Adapter for VMware vCenter Site Recovery Manager 5 — supports automated failback from a disaster event and new work flows for planned migrations and downtime. Dell also is updating its Compellent plug-in support for VMware vSphere 5 to help customers more easily link together their Compellent storage environment with virtualized resources.  

· Dell PowerVault Integration with VMware vSphere 5 — adds certification and enables customers to manage multiple PowerVault MD3200/MD3600 series of storage arrays from a single VMware vCenter Server instance using the vCenter Plugin for Dell PowerVault MD. The Dell PowerVault MD storage arrays (iSCSI and Fibre Channel) also support VMware vSphere Storage APIs for Storage Awareness. The PowerVault MD3600f/MD3620f series of storage arrays support VMware vCenter Site Recovery Manager 4.1 and 5 using the Dell PowerVault Storage Replication Adapter(SRA).

New Software Enhancements Deliver Enterprise Storage Sophistication with SMB Simplicity

Dell today introduced additional capabilities to help customers gain insight into their storage environment and also better integrate with Microsoft virtualization offerings. Offering integrated, all-inclusive software, the EqualLogic platform retains its ease of management as the system scales. New solutions that bring enterprise-class functionality to smaller implementations include:

· Dell EqualLogic SAN Headquarters 2.2 software — includes new multi-site support so customers now can easily monitor the health and activity of their storage environment across different geographies. The solution provides ongoing, real-time diagnostic information to enable customers to optimize and tune their system for performance and efficiency.

· Dell EqualLogic Host Integration Tools for Microsoft 4.0 — re-designed to enhance the usability experience with new features including centralized data protection and more efficient management of multiple Microsoft hosts and virtual machines. Enhanced Clustered Shared Volume (CSV) support has been designed to streamline data protection for CSVs and improve capacity utilization. 

“The new EqualLogic capabilities mark a significant next step in the evolution of the Dell Fluid Data architecture and extend Dell’s leadership in virtualized IP-based storage solutions that are easy to manage.  The new storage arrays and virtualization tools can help our customers run highly optimized and efficient data centers by automating configuration and improving performance without forcing forklift upgrades.” – Darren Thomas, vice president and general manager, Dell Enterprise Storage
