I noticed on host running VMware ESX sometimes HA gets disabled because of network glitches, even trying it from Virtual Center client I wasn’t able to turn it on. I like playing with command line options when Virtual Center GUI fails to work. Here is a command that i used to enable HA back on my VMware ESX host.

Steps to enable HA by command line in VMware ESX host:

1. Login as root into ESX host using ssh :

2. Run service restart on ESX host for enabling HA:

One VMware management service restarts you can re-enable HA back

Here is my horror story how Trojan affected by Windows Vista machine and left it unusable. I am not sure how my Pc gets this Trojan. I use Trend Micro Antivirus and that does a pretty good job for stopping Trojan attacks.

I keep my Trend Micro up to date and run weekly virus scan. This Trojan turned out to be very notorious my Trend Micro antivirus wasn’t able to detect the attack and this Trojan sneaks into my Windows vista PC. I am posting details how I managed to fix it, not for free though I have to purchase some security software’s.

Last week my Home desktop got infected by a Trojan that left my Windows Vista machine to crash nonstop. I notice this pop up saying my PC is infected by a virus and noted a shortcut named Antivirus scan. I realized I am under attack by a Trojan I booted my Windows Vista into safe mode, booting in normal mode my Windows vista machine was crashing after running for 5 minutes. I ran trend micro scan and safe mode and booted my desktop but it crashed again. I searched online and find this software called “Security Task Manager”, a trial version showed me that there are some unidentified executables running on my PC but I couldn’t remove it so I have to purchase this piece of software for $29 . I purchased online this software called “Security Task manager” and removed three executables called “YUR1d22.exe”, YUR1e23.exe and “YUR1f43.exe”. But wait don’t purchase this software if you are having similar crash issue on your windows Vista desktop. This didn’t fix my problem because there were some registry entries made by Trojan into my Windows vista registry and Security task manager doesn’t clean registry entries inserted by Trojan software in Windows vista .

I was aware of spybot and Adware so I downloaded these programs with hope that they can remove Trojan from my Windows vista desktop and also clean Windows registry. Adware is available as free download you can download Ad-aware 2008 from Adware website. Similarly Spybot is free as well and it’s worth a try, you can download spybot from here. I booted my Windows vista desktop into safe mode and ran a complete scan and find lot of spyware and adware, I removed all of them and restarted my Windows vista desktop , after running for 4 minutes it Crashed again and I realized I am going to loose my hard drive if my PC is not going to get out of nonstop crashing mode.

I start giving up when Adware and spybot didn’t fixed my problem I did few more searches online and find this piece of software called SpyHunter, running trial version of spyhunter looks promising because it was able to get inside Windows vista registry entries and did notify me of some Zango adware and other spyware. I purchase SpyHunter security suite and installed it quickly. I liked SpyHunter because it says if you can’t fix your problem then you can call their Technical support and they will work with you to remove Trojans, adwares, spywares issues.

I ran a complete scan of SpyHunter by booting my Windows vista pc into safe mode and removed all detected Trojans and other parasites. What a surprise I booted my Windows Vista desktop and left it running whole night it didn’t crashed whole night. I must say THANKS to SpyHunter and want to share this online if you are having similar issues where your Windows vista or Windows XP machine is crashing nonstop chances are there is some stubborn Trojan sitting on your PC watching your every move using keyloggers.

Bottom line I give 5 star rating to SpyHunter and recommend you should buy this if your Windows vista/XP machine is infected by Trojans and crashing nonstop.

Last week while working doing new VMware View setup i was deploying some Windows XP desktops running as VMware ESX guest , i noticed some weirdness.

I received this error when i was deploying Windows XP workstation from VMware Virtual Center :

A general error occured : Failed to create journal File provider

Strangely enough i created several desktops before but when i was working on fresh Windows XP VMware virtual desktop deployment it failed when i tried to power-on the VMware virtual desktop.Looking closely into the error message it appeared to me that something is wrong on VMware ESX host server where /var/log filesystem uses journaling . The /var/log file system on VMWare ESX stores all log related to alerts, monitoring and all operations related to VMware guest OS.

So i logged onto the esx server using ssh from my Putty terminal. By running a quick df -h on all filesystems , i noticed /var/log was 100% , to me that definitely sounds wrong.I removed some older archived kernel alert files to free up some space and then Jumped back onto my Virtual Center Console . As soon as i powered-on the Windows XP VMware guest it worked very well without any error message. So if you are getting this errror “

A general error occurred :Failed to create journal File provider” ,

then look into /var/log filesystem on VMware ESX host for disk space.

One fine morning when i was booting my Dell running Windows Vista ultimate i didn’t realize that a surpise is waiting for me. I opened my  DELL Studio 17 Laptop and powered it on guess what…. Windows Vista running on my Dell laptop failed to boot and i was greeted with this error message :

NTLDR is missing

I tried powering back it off and on several times but i had same NTLDR is missing error.I am not sure what caused this error but that defineltly sounds like there is something wrong with Master Boot record (MBR). I had Windows Vista ulitmate installation DVD close to me so i thought of fixing this error by booting it from DVD media.Here is how i was able to fix the NTLDR is missing error :

Fixing NTLDR is missing in Windows Vista :

1.Insert the Microsoft Windows Vista installation DVD disc in the DVD drive, and then start the Laptop.
2.Press a key when you are prompted and Select language, time, keyboard or an input method, and then click Next.
3.Select Repair your computer
4.Select the operating system that you want to repair, and then click Next.
5. In the System Recovery Options dialog box, click Command Prompt.
6.To Fix NTLDR is missing error in Command prompt type this command and hit ENTER:

bootrec /FixBoot

That’s was really quick to get my Windows Vista Laptop back to life. Unlike Microsoft Windows XP i didn’t see any NTLDR or NTDETCT.COM files on Windows Vista. Windows Vista is different compared to XP, i remember NTLDR missing error in Windows XP where you can simply copy these two files to fix the issue.I just want to point out things have been changed in Windows Vista and for those who are still in hangover with Windows XP they will find little surprising to see new command to fix NTLDR is missing error.

VMware launched First Free, Open-source VMware View desktop Linux client. On Feb. 03 VMware announced Free Open-Source VMware View client download availability. In December 08, VMware released new version of VMware desktop Infrastructure now called VMware View which allows users to access desktop, laptop and VMware virtual desktops through web browser or by installing VMware View Client. VMware View client was only available for Microsoft Windows users and there wasn’t any client available for Mac OS X and Linux users, since then lot of VMware users complained about releasing VMware View client for Linux and Mac OS X.

Finally VMware listened to their customers valuable advice and released VMware View Open clients for Linux that can be run on all Linux distributions including – Red Hat, Novell Suse Enterprise, CentOS, Fedora and Ubuntu Linux. VMware is facing strong completion from Citrix who offers their own Desktop virtualization solution which is pretty attractive to customers who are looking to bring unified virtual desktop solution into their IT environment, Citrix virtual desktop can be  accessed from any operating system - Linux, UNIX, Windows and Mac OS X because Citrix virtual desktop client uses own proprietary protocol called ICA (Independent computing Architecture) .VMware announcement of free VMware View Linux client is smart move for VMware, also i heard from reliable sources that VMware Mac OS client is underway that is going to be released pretty soon. These new VMware client releases (Linux and Mac OS X)  will put VMware View ahead of Citrix desktop offering.

VMware View Open Client is available under GNU public License as free downloads . You can download VMware View Open Linux client from Google code.

In VMware ESX 3.5.x running VMFS3 filesystem there is limitation on file size which results in error if you are trying to create Guest virtual machine with large disk drive. For example if you are trying to create a guest VM with disk drive size larger than 256 you will get this error :

File is larger than the maximum size supported by datastore.

This happens because by default VMware ESX running VMFS3 uses 1M blocksize with a limitation of 256 GB disk size for the guest virtual machine. However it is possible to change or rather increase the size of disk drive that you can create for the virtual machine. If you can change block size to 2M on VMFS3 filesystem on your ESX server you can create disk drive upto 512GB size for the virtual machine.VMware Recommends following block size to create large disk drive on virtual machines :

1M Block Size max VMFS-3 = 256G
2M Block Size max VMFS-3 = 512G
4M Block Size max VMFS-3 = 1024G
8M Block Size max VMFS-3 = 2048G

File size larger than 2048 GB is not supported on VMFS3 filesystem, using VMFS2 you can go upto 16 M block size but that option is not available on VMFS3 filesystems.To changethe block size on a VMFS3 filesystem you can use vmkfstools command from command line ro reformat the parition. The vmkfstools command can be run on ESX server :

#vmkfstools –create vmfs3 –blocksize 2M vmhba1:0:0:2
