Problem with hard stop and guest OS - question of VMotion

Hi all! I'm having a problem and I hope I can find help...

Basically, we are in the middle of HA and VMotion test and we found that when we make a hard stop on one of our boxes of ESX 4 (simulating the loss of an ESX box), the guest operating system disconnects and stops on the ESX host that cut us off. He does VMotion off for another host ESX in our environment and then restarts the VM guest save... Anyone has any ideas of why it does this? It should be keep alive, no?

I have install multiple ESX 3.5 environments and never had this problem and hoping maybe I am missing something in ESX 4.

Thank you!

false, he did exactly as it was designed... the name chosen for HA is perhaps not the biggest.

It should help you understanding between the HA and FT:

Essentially if you want continuous availability, without interruption, you need to implement VMware FT (Fault Tolerance) While HA, will try to minimize downtime as little as possible, but it's time to stop, as you saw.

  • Problems with Windows Update and load XP SP3

    I had a problem with my system and had to replace my HARD drive and reload XP and all my applications and data.  Now, I installed SP2 and try to install SP3. Windows Update does not work (get the 080244019 error code x) and when I try to install the SP3 files from the Microsoft site, it'll run about halfway through and then stop and hang, displaying the message "Finish Installation" with bar at halfway of the progression.  I tried the MSRT and FixIt nothing helps.  I checked services.msc to see all the required services are enabled or started.  I read that some malware will be stop some services without notice.

    After a few attempts to load the file SP3 failed, check Add/Remove programs in Control Panel Windows XP Service Pack lists 3 but no file size or to update the date information as with other programs.  My browser is IE8 and I was doing some Hot fix for Windows XP downloads, this adventure started about 3 weeks ago, but no other automatic update downloads.  I use the following McAfee provided by my ISP for protection AV and firewall with regular full scans.  Scan today revealed there is apparently a single trojan file that cannot be deleted, but there were no further details.  My system is also fully functional; I seem to get the updates for McAfee and other applications OK but not SP3.  I received or otherwise installed following updates or Hot Fix for XP downloads in the past 3 weeks:

    Thanks for the quick response.  I did some checking on my system, I have XP Home Edition ships with the system bought in July 2007.  Add/Remove Programs shows that the aborted install XP SP3 and IE8 installation; I tried to load the SP2 file but it doesn't show here as an addition, so it may have been part of the original XP CD and I just crush.  Even for IE7 so I am not able to drop back to all recommend you.  I will try your solution later today and post my results. I saved SP2, SP3 and IE8 in my office and a flash player to reload later according to your instructions.  Stay tuned.

  • Satellite Pro C650D - problems with the audio and game controllers

    Hello

    I recently had problems with my microphone and speakers/headphones and game controllers.
    Sometimes the microphone stops working when on Skype, for example, but most of the time works fine, once again, when I restart the pc.

    Stakeholders sometimes still work when I connect headset.
    Some of the sounds are still coming through the speakers while some coming through the headphones.

    I have a usb game controller which also did not work everything properly.
    If I assign buttons in the program that they do not work in the game.

    All these devices are in Device Manager in a group that makes me think it's sort of annoying update doubtful that messes with them.

    Any body have similar problems or know what to do better?

    See you soon
    Laurin

    Hello

    Can you please send some details on the laptop model and the system you are using?

    With regard to the issue of sound/mic:
    > The microphone sometimes stops working when on Skype, for example, but most of the time works fine, once again, when I restart the pc.

    Are you talking about internal microphone or external? This only happens using Skype?
    In your case I would test the microphone using different applications to make sure that is not a Skype related issue.

    > Yet sometimes the speakers work when I connect headset.
    I recommend this thread:
    http://forums.computers.Toshiba-Europe.com/forums/thread.jspa?threadID=65295

    The user has had a similar problem, but this phenomenon was linked to the Realtek HD Audio Manager settings.
    She wrote:
    + In the upper right corner, there is a small yellow folder called "Connector settings" in my version. +
    + There, finally I could re-enable the setting "enable popup dialog box, when the unit is plugged. +

    + So now when I plug an external speaker or headphones, it appears, and I select the option "helmet" (instead of "line-in"), and then the sound only through the headphones/ext.speaker.+

    Regarding the game controller:
    > I have a usb game controller which also did not work everything properly.
    > If I attribute buttons in the program, they do not work in the game.
    I put t think its problem of laptop in my opinion, you must make sure that the controller is compatible with the games you play and also recommended to check some info provided by the manufacturer of the game controller.

  • HP 15 laptop: problem with the touchpad and the key "stuck."

    Hello!
     
    Last weekend, I have an irritating problem with my HP 15 laptop. Bought two years ago and upgrades to Windows 10 a year ago.
     
    First of all, my touchpad started to not work properly. It "freezes" and I can't use it until I click the ESC key, but it doesn't last and "freezes" again a few seconds later. Then, everytime I open a window where there is a text box (Start menu, edge browser, Control Panel, etc.), the number 5 is entered automatically and permanently, as if the button 5 has been blocked. I did a quick check and button 5 do not seem physically stuck.
     
    Yesterday, I restored the system to the factory settings, so I'm back to 8.1 for Windows and then upgraded to Windows 10. Everything seems to work fine, but this morning, the problem was back. Is there something I can do? What is the problem caused by Windows 10 or the computer? Should I restore it to Windows 8.1? Everything worked great til last weekend, I don't know what that was.
     
    Thank you in advance for your help!

    Welcome to the HP support community @gouch3.

    I understand that you have a problem with the keyboard and the touchpad on your laptop from HP 15.

    Have you tried to use a keyboard external and mouse at all?

    Have you tried to go to Safe Mode to see if the problems persist in there?

    Have you tried to perform a material or forced reset Reset?

    Did you do a test of material?

    Have you updated your drivers?

    It could be a driver problem to be able to look at that for you, I need your model number. I wish I could give you an answer or not, but at this point without the troubleshooting results and the model number, it is difficult for me to say.

    I can say that if everything works in point 8.1 of Windows without problem, the driver TROUBLESHOOTING is a great place to start. Please try to follow these steps for the keyboard and the touchpad of troubleshooting:

    • Beginning
    • Search for Device Manager
    • Search results, open Device Manager.
    • Click on display
    • Show hidden devices.
    • Click the arrow next to keyboards.
    • Right click on the name of the keyboard device.
    • Select uninstall.
    • Continue deleting the names of devices in the category keyboards until the feature of all the names have been uninstalled.
    • Restart the laptop twice.

    Touchpad:

    • Type of research, "Device Manager."
    • Click on Device Manager,
    • Expand mice and other pointing devices.
    • Right click on the TouchPad,
    • Click on uninstall.
    • Restart the computer laptop twice,
    • Reinstall the TouchPad card.

    I found a document of troubleshooting for you to try also called Portable keyboard troubleshooting. Please be sure to follow the steps described in this document.

    The best document I have for TouchPad problems is the use and troubleshooting of the TouchPad and ClickPad document. 

    Here is a link to the HP Support Assistant, if you need it. Just download and run the application and it will help with the software and drivers that need to put up-to-date.

    This is a great question other clients may also be questioned. When we came to a resolution, please share what has worked for you with others by marking this post as an acceptable Solution. If you want to show appreciation for my efforts today, please take a second to click the Thumbs Up button below.

    If you need assistance, I would be more than happy to continue to help you. Please re-post with the results of the resolution of the problems. Could you please also provide your model number (How can I find my model number or product number?)

  • I have a problem with file compression and then not be able to extract their share at a later date

    original title: file compression

    I am running Vista Home Premium on my laptop. I have problems with file compression and then not be able to extract their share at a later date. For example, I sent a file compressed to my instructor and she pointed out that she had a .zipx extension and the fact that she was unable to extract the files of ranking. Can someone help me with this problem?

    Hello

    1. do you have a third party compression/extraction of software installed on your machine?
    2. do you get an error message when you try to extract the files?
    3. is the relevant question for the particular file type?
    4. don't you make changes to your computer before the problem?

    Follow the steps and check if they help.

    Step 1:

    Open zip files is to open the folder and drag the content to another folder.

    See article:
    Compress and uncompress files (zip files)

    Step 2:

    If you have a third party software to Compress/decompress, I'd Uninstall it employs the way Windows compression and decompression of files/folders and see if they help.

  • After the last updates of windows have problems with start up and now drivers

    Hello

    After the last updates of windows have problems with start up and now drivers. I get an error code 21 when I try to install the drivers AMD apparently missing.

    May 14, last night I had several (automatically) downloaded windows update

    Today, I was unable to boot my computer with Windows - tried the disk check, start checks etc, and eventually had to use System Restore (for help before the critical update to restore).

    Perfection, everything works, but knowing that windows will attempt to redo an automatic update, tried to check online - no one seemed to have a problem and (naivly) thinking I could always do another restore of the system, I rebooted again.

    Same thing worse. Could not do a sys restore either just before restarting or last night. Chose a date earlier (last week) but then lost the USB drivers and pilots display. Downloaded updated but refuses to let my AMD driver install Windows I have a very unpleasant screen... and I must now stop the installation of this update "critical."

    Would appreciate advice how do my installed display driver or whether anyone else has problems following this update

    Thank you

  • Anyone having problems with Windows 7 and the HP LaserJet P2035n?

    It seems, after a few months of service, there are several problems with this printer and Windows 7 only.  We have several offices that use this printer and almost each one has similar problems.  It will printer randomly disappear, not being able to print anything at random times of the day, to the spooler crashing every two minutes or more.  There is no problem at all with Windows XP or Vista, only 7.  Reinsalling the printer driver takes care of the problem for a few days, but the questions up all over again.

  • Photoshop elements 13 said that there was a problem with the download and recommend exit us and restart

    We bought a new laptop and 13 items today. We spent the day trying to get it set up. We tried to download the 13 items at least 6 times. Whenever it took about 45 minutes to download, but when we open the file and click on set up it says that there was a problem with the download and it recommends that stop, restart and download it again? How we work what goes wrong? We had to remove the files and start every time. I don't have another day to try to get this sort. Should not it is just a matter of downloading and then, should not come with a message to install and we just press Yes and it works.

    You can also download the trial version of the software directly (No Download Manager) through the page linked below and then use your current serial number to activate it.  You should get two files, an executable file and a compressed file.  Run the executable file and it will install the rest.

    Don't forget to follow the steps described in the Note: very important Instructions in the section on the pages of this site download and have cookies turned on in your browser, otherwise the download will not work correctly.

  • Problem with the locale and date serialization in java

    Hello
    I have a serious problem with Flex dates and need a solution as soon as possible. I have a Flex 2 front end that uses remote java objects to talk to the database. I have a Flex 2 DateFields form. The dates of these are stored in the datebase. However I need the dates to be stored exactly as users them selects regardless of the locale.

    What is happening at the moment is we are developing in Ireland and in selecting a date, filling an actionscript VO which is in turn transformed into a java VO (on a server in the United States) and when the date is stored in the database is one day before the date that we have selected. It seems that the flash player uses the locale with a time of midnight (GMT) users. When place the conversion to the EAST, it stores the date (GMT - 5), which causes the being Eve.

    I changed my flex code to set the date at 12: 00 time even if he converts and subtracts 5 hours it will always be the same date. But this does not work, it seems to work sometimes and not others and is very inconsistent. I can't understand why it works sometimes.

    Its makes me mental - someone has experienced this problem or did someone knows a solution PLEASE?
    Thank you

    I'm not very familiar with your specific question, but I wonder if a combination of store dates as the first milliseconds since midnight January 1, 1970, universal time, stored as a string and then when presenting the data are aware, locale would solve the problem.

  • How can I return to 6.3 4.0 I have never had a problem with 3.6 and now 4.0 crashes all the time tell me how to go back

    How can I return to 4.0 3.6 I've never had a problem with 3.6 and now 4.0 crashes all the time tell me how to go back

    Downgrade to Firefox 3.6 first of all uninstall Firefox 4, but do not select the option 'remove my Firefox personal data '. If you select this option, it will delete your bookmarks, passwords and other user data.

    Then you can install the latest version of Firefox 3.6 available to http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your favorite courses, passwords etc.

    I recommend, to avoid possible problems with decommissioning, accessing your profile folder and delete the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Delete these files will force Firefox to rebuild the list of installed extensions, check their compatibility and cancel the toolbar customizations.
