$ = 'monitor_control. Instead they recommend vMotioning your VMвЂ™s. Note: VMware removedВ line 13 from their KB because they discovered thatВ self-migration didnвЂ™t always perform the Fast Suspense Resume (FSR) required to activate the changes. The script then performs a stationary migration (the VMВ doesnвЂ™t change hosts) which applies the new configuration. Server 2012 VMвЂ™s show up as windows8Server64Guest. DonвЂ™t worry about the line where it searches for guestid like windows8*Guest.

The script adds the advanced option to all affected VMвЂ™s. If after the installation of a bad update Windows doesnвЂ™t boot in the Safe Mode as well, boot your computer from any available DVD/CD disk or USB drive: it can be Windows Recovery Environment ( WinRE ), Windows installation disk, ERD ( MSDaRT) repair disk or any other bootable drive. Access the Safe Mode by pressing the F8 key while the system is booting up.

Thankfully, VMware has offered a great PowerCLI script to get the job done. If your Windows 7 is stuck into an infinite Startup Repair loop after an update, you can try to roll back the Windows 7 update in the Safe Mode (since the Windows cannot boot as normal). If youвЂ™re like the rest of us, you canвЂ™t afford to bring down each VM and edit it manually.

Name: monitor_control.enable_softResetClearTSC.

C# Client: Edit Settings -> Options -> General -> Configuration Parameters.

Web Client: Settings -> VM Options -> Advanced -> Edit Configuration.

If you have the time and flexibility to power down each VM, simply navigate to theadvancedparameters of your VMвЂ™s settingsвЂ¦.

Otherwise the option to edit advanced settings is greyed out. You must add an advanced parameter that will reset the TSC of all vCPUвЂ™s on a soft reset.В What they donвЂ™t tell you is if you want to use the GUI (Web or C# Client)В to make the change, youвЂ™ll have to power down the VM first. They doВ offer a fix, but this requires a slight change of each VM. To restore the files, follow these steps: Step 1. This issue only occurs on version 10 virtual hardware due to the hardware clock mechanism. If the Boot loop is caused by the presence of corrupted files in your hard drive, you can restore a clean copy of the same files previously-stored by Windows.

The problem is that Windows only resets the counter on CPU0, and a discrepancy between multiple vCPUвЂ™s can cause the OS to hang at boot up. That is to say, the VM has been running for about two months, or longer, without being powered off. When Windows reboots, it resets this counter if theВ value is equal to or larger thanВ 18,014,398,509,481,984. Each processor has a TimeStampCounter (TSC) which is essentially an odometer that counts how many cycles the processor has run since its last reboot. It turns out this is a known issue and VMware has released KB2092807В to address it. After a few hours they mightВ come up, but more often than notВ a hard reset is required to bring them back. Lately,В weвЂ™ve been receiving alerts on many of ourВ Server 2012 VMвЂ™s, and upon investigating weвЂ™ve found these guests to beВ hung at the Windows boot screen.

ItвЂ™s patch week again which means many guest reboots in our VMware environment.
