OVM 3.0.2: slow startup after updating to 3.0.2

Hi,
I just updated my VM servers to 3.0.2 and now each host sits at "Starting udev..." for 3 mins. before proceeding with the boot process.
Anybody else noticed this?

3.0.2... aye,...
alright then. This is a compounded problem created over a number of packages.
the most problematic issue is that during install the main source of the trouble got squirrelled away into the /boot/initrd.img file so an updated version of mkinitrd would be needed at some point
However, to get everyone moving again
edit /etc/udev/rules.d/50-udev.rules
spin through the file until you find this these lines
KERNEL=="rtc|rtc0", MODE="0644"
KERNEL=="rtc0", SYMLINK+="rtc"
just snip those out and save the file.
The upshot is that /dev/rtc (created from the initrd.img) is present on a rebooted system that points at 10:135 rather than 252:0.
Most likely the only program of importance that will care/malfunction is hwclock. Other programs will correctly use /dev/rtc0.
Basically there is a fault where /dev/rtc is created as a real device by the initrd.img ramdisk
udev tries to create a symlink from rtc0 to rtc which it can't do and rather than just failing it runs around in a tight loop trying to create a symlink without removing /dev/rtc first
Oh,.. my comrade is telling me to remind you that as a fix, this is unsupported and that your should raise an SR if you haven't done so already.

  • No System Startup after Update 10.4.10 - Help?

    Hi,
    after updating to 10.4.10 Mac OS X was not completely startup. It was hanging at the end of the blue loading bar every time.
    I was running the Hardware Test on the OS X Installation DVD and the harddrive testprogramm. Everything was ok. I could start the system in the "Safe Mode". I read that a new system installation could fix startup problems. So I reinstalled OS X. Everything was running OK. Then I updated to 10.4.10 again and I have the same Problem again!
    I read about a quicktime component problem, so I reinstalled Quicktime in the "Safe Mode" like they were writing, but nothing helps.
    After the Update to 10.4.9 my system seemed to be slower, but now it does not even startup. It always hangs at the end of the blue loading bar.
    My System:
    MacMini - 1,83 GHz (Intel)
    1 GB-RAM
    SuperDrive
    AirPort
    80 GB Harddrive
    Any ideas??
    Thanks for help.

    Welcome to Apple Discussions!!
    I could start the system in the "Safe Mode".
    Well try a normal startup, that fails, then start up in Safe Mode and immediately use the Console application (in /Applications/Utilities) to look at your system.log. Go back to where it says "reboot by <user>" and look at the lines immediately before that. Post some of them here.
    If it starts OK in safe mode, but not otherwise, then there may be a problem with one or more of the items listed in Mac OS X: What is Safe Boot, Safe Mode?.
    Since you don't get as far as being able to log in, it is unlikely that Login Items are a problem. Equally it is not likely to be the font caches mentioned since they are user specific. I would be inclined to start with the fonts in /Library/Fonts, and then work backwards in the list.
    See these User Tips for more about fonts:
    Font Management in OS X Panther (Kurt Lang)
    Fonts and Apple Type Services, part 1 (J.Otava)
    Fonts and Apple Type Services, part 2 (J.Otava)

  • Slow editor after update

    Is it my imagination, or has there been a performance hit after update 1? After heavy use, I've had to restart eclipse in order to speed things up, which seems to help for a short time, but eventually the editor slows down again, particularly on large CFC files with a mix of CF and HTML code. Sometimes I have to wait a couple seconds after each editor change before I can do anything, which is problematic when you're trying to move quickly. That's when I just restart and say F###! Everytime this happens, the little tractor track progress icon moves. Not sure what it's doing since it goes away too quick for me to click on it. Could it have something to do with syntax highlighting? I notice that the screen flickers a lot after each editor change, which is also annoying.
    I can't wait until CFB becomes a stable and fast because it's DEFINITELY NOT!

    I think I've resolved my performance issues by increasing the memory size of eclipse... I modified the eclipse.ini file from:
    -startup
    plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
    --launcher.library
    plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
    -showsplash
    org.eclipse.platform
    --launcher.XXMaxPermSize
    256m
    -vmargs
    -Xms40m
    -Xmx256m
    to:
    -startup
    plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
    --launcher.library
    plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
    -showsplash
    org.eclipse.platform
    --launcher.XXMaxPermSize
    256m
    -vmargs
    -Xms128m
    -Xmx512m
    (changed: -Xms40m to -Xms128m and -Xmx256m to -Xmx512m)
    So far the performance has been acceptable. I've been using these settings for about a week or so, and so far I haven't had any serious performance issues.

  • Slow computer after update to 10.7.4.

    After updating to 10.7.4., my MacBook Air (2,13 Ghz Intel Core 2 Duo, 2 GB 1067Mhz) my became very sluggish. Logging in lasts 5 minutes, all programmes are very slow, internet is slower, even typing is something difficult. Do you have any suggestions to remedy this situation ?

    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
    Step 1
    Select "system.log" from the file list. Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged during the time something abnormal was happening. That time might be before or after the boot.
    For example, if the problem is a slow startup taking three minutes, post the messages timestamped within three minutes after the boot time, not before. If the problem is a system crash or freeze, post the messages from before the boot time, when the system was about to crash or was failing to shut down. In either case, please include the BOOT_TIME message at the beginning or the end of the log extract.
    Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
    If the log doesn't go back far enough in time, scroll down in the Console file list to /private/var/log/system.log.0.bz2. Search that archived log, and if necessary the older ones below it, for the same information.
    Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
    Step 2
    Do the same with kernel.log.
    Step 3
    Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall or hang logs — they're very long and not helpful.

  • AirPort very, very slow & intermittant after update

    I installed the AirPort Extreme Update 2007-001 from today's Software Update, and on restarting, my wireless connection became extremely slow (56k speeds at best) and very intermittant -- it'll work for a minute or so, then lag for two or three minutes with no signal. I've rebooted several times, but it hasn't helped.
    Is anyone else having trouble after the update?
    MacBook Pro, 15"   Mac OS X (10.4.8)  

    The "solution" is at http://www.macfixit.com/
    Problems after updating
    [In many cases, the problems listed below are incidental to the update and can be solved by some of the workarounds listed in our wireless troubleshooting tutorial -- many users have reported success with turning off wireless encryption (WEP, WPA) on their Base stations, for instance.
    If you are having extreme difficulties after applying this update, the workarounds listed in our wireless tutorial have failed, and you absolutely need to restore wireless access, you can try this somewhat risky workaround:
    Download the most recent version of Mac OS X for Intel (10.4.8)
    (http://wsidecar.apple.com/cgi-bin/nph-reg3rdpty2.pl/product=11796&cat=1&platform =osx&method=sa/MacOSXUpd10.4.8Intel.dmg)
    but do not install it.
    Download and install the shareware application Pacifist
    Drag the Mac OS X 10.4.8 installer package onto the Pacifist application icon.
    Click the triangle next to "System" to expand it
    Click the triangle next to "Library" to expand it
    Click the triangle next to "Extensions" to expand it
    Scroll down and find the file IO80211Family.kext. Drag it to your Desktop or another location (you will have to enter your administrator password)
    On your Mac OS X startup drive, navigate to /System/Library/Extensions and locate a similarly named file (IO80211Family.kext). Move it to another location for safe keeping.
    Now drag the file from step 7 (the one that you retrieved from the Mac OS X 10.4.8 install package) into the /System/Library/Extensions, in effect replacing the newer file (installed by the AirPort updater) with and older copy -- you will have to enter an administrator password.
    Restart your Mac
    This workaround is risky because you should not generally mix and match kernel extensions after updates, you will lose some improvements (including security refinements) brought about by AirPort Extreme Updater 2007-001, and new conflicts can ensue. Still, in a bind, it can restore wireless connectivity where other workarounds fail.]

  • Windows 7 Bootcamp is no longer available in startup after updating to Yosemite 10.10

    I updated my MacBook Pro (Retina, 15-inch, Late 2013) and then after updating I could no longer see my Windows 7 bootcamp when starting up.  I followed this tutorial to try to get it too work again without losing any information: Windows 7 Removed after update Yosemite.  I got to the part where we rebuild the MBR, but I got to part 8 and then it said that partition 4 is either too big or does not exist. 
    I do not know what to do from here and was wondering if I had done something wrong and/or what I can do to fix it?
    Thanks in advance

    You seem to have found the correct partition. The following table has your values. (ASC thinks I have invalid characters in my table, so this is a screen shot of the MS Excel spreadsheet).
    Leave your Testdisk display and start a new Terminal Window. You need to use the following steps. If you see any error messages during the following steps, please stop and post back here with the error message. The following steps have values from your Testdisk output (and you can verify) in Steps 7 and 8.
    Rebuild GPT4 using start/end offsets
    Sudo gdisk /dev/rdisk0
    P  (print the full list of parts)
    D  (delete)
    4  (part 4)
    N  (new part)
    4   (part 4)
    589682688 - Start offset in bytes  (start point for Bootcamp part)
    +387422201 -  (Size offset as opposed to End offset)
    0700     (Windows part type)
    P           (print list of all parts just to see what changes will be made)
    W         (Write the new GPT)
    Y           (Yes! really write the new GPT)
      This will delete and re-write the GPT partition info for /dev/disk0s4.
    Rebuild MBR to match the new GPT information thus resetting the Hybrid MBR. Use defaults for other questions (like partition codes). The only values that need modifications are the Boot flags and step 6. Accept all other defaults that Gdisk offers.
    Sudo gdisk /dev/disk0
    P  (Print list of parts)
    R   (Recover)
    H (chooses Hybrid)
    Partitions numbers to be hybridized: 2 3 4
    Y (Good for GRUB question)
    N (part 2 boot flag)
    N (part 3 boot flag)
    Y  (part 4 boot flag make NTFS bootable partition)
    W  (Write the new MBR)
    Y    (Yes! write the new MBR)
    Reboot
    Here is a sample Q and A for the second set of Gdisk steps.
    Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): Y
    Creating entry for GPT partition #2 (MBR partition #2)
    Enter an MBR hex code (default AF): Press Enter/Return
    Set the bootable flag? (Y/N): N
    Creating entry for GPT partition #3 (MBR partition #3)
    Enter an MBR hex code (default AB): Press Enter/Return
    Set the bootable flag? (Y/N): N
    Creating entry for GPT partition #4 (MBR partition #4)
    Enter an MBR hex code (default 07): Press Enter/Return
    Set the bootable flag? (Y/N): Y
    Test 1 - Does Bootcamp Volume show up in Finder?
    Test 2 - Can you see files in Bootcamp Volume?
    Test 3 - Can you select Bootcamp in System Preferences -> Startup Disk?
    Test 4 - If Test 3 is successful, select Bootcamp and Click Restart.

  • Mac Mini 2011 slow down after updating to Yosemite

    Hi all!
    After updating my Mac Mini (half 2011) from Mavericks to Yosemite, it became extremely slow and unresponsive. I have to wait a lot of time for apps to open and commands, like clicking a button, to be executed executed. File Vault, that I read is a common cause of slow down, is NOT enabled.
    What should I do? In these cases, for my Windows PC, I insert the OS DVD and format: what's the equivalent operation for a Mac?
    Thank you in advance for your help!

  • Spinning gear on startup after update

    After updating my mac mini to OS 10.9 all I get is the spinning gear upon startup. Tried booting in safe mode but got the same result. Is there a way to fix this without reinstalling the OS. Thanks

    According to the link below, this is a problem with the display server crashing and that you can boot the Mini if you unplug the display, give it a few minutes, and then plug in the display:

  • Mac Mini shuts down during startup after update

    I've got a Late 2009 Mac Mini running Snow Leopard Server. Occasionally, it takes me awhile to restart after updates, so this could be due to the most recent update or possibly the combination of the last two...
    I went into my office, saw that there was a Safari update and decided to let it do its thing. When I came back 30 minutes later, my machine was off. I turned my machine back on, got the gray Apple screen with the spinning cog and the progress indicator for the update. A little over 10% through, the progress indicator reset. No biggie, I figured. Second time it got to the same point, it just shut down. Nada. When I restart, it does the same thing.
    I've tried resetting PRAM.
    I've tried resetting SMC.
    I've tried booting in safe mode, but that isn't working at all – just does the same thing as when I (fail to) boot normally.
    Everything but one of my screens and my keyboard is disconnected. ****, I even tried booting without either one connected (I just waited to see if it would turn off), and it failed.
    Can't think of or find anything else.
    Anyone?

    Humm.. you'll need to startup from your System Install Disc to test, repair or restore from Time Machine.
    Some options for Starting up from your Install Disc include:
    1. in an External Optical DVD Drive.
    2. from another iMac in Target Disk Mode.
    3. from a copy on a Thumb Drive or External HD.
    It's to bad that you are using Time Machine on the second HD instead of a clone with Carbon Copy Cloner - Home or SuperDuper! that you could boot from for testing, repairing and/or restoring.
    If none of the above helps?
    There is one good thing about a Mac Mini, it is much easier to tote into the local Apple Store or AASP than an iMac. see > Apple - Support - iMac - Service FAQ

  • Has anyone got slow browsers after updating to 10.8.4

    In the last couple of days, both Safari and Firefox have shown very "jerky" performance - sometimes pages load very quickly, at other times loading stalls for a while and then restarts. With Safari, I get a spinning ball until the blockage clears itself. Running my ISP's (BTInternet) own speedtest when this stalling occurs, shows a speed near to dial-up whereas it should be near 30+Mb as I am on fibre. As soon as the stall clears, the speed reverts to normal.
    CPU useage, memory, disc space etc are all normal, I have tried rebooting the modem and router, and changing from wifi to ethernet (via Powerline adapters) has no effect. This seems to have happened after updating to 10.8.4 but, given that everthing else seems to be working properly, I am reluctant to blame this, and suspect my ISP and/or its modem or router. Has anyone else noticed problems with their browsers since 10.8.4 and, if so, found a cure?

  • Slow charging after updating my iPhone 5S to iOS 8.1.1

    Hi,
    I just updated my iPhone 5S - 16GB to iOS 8.1.1 (from 7.1.2) few hours back and it took 90 minutes to charge 6% (It was in 74% or 75% when I plugged in and it came to 81% after 90 minutes)
    I tried rebooting my Phone - No Luck
    What do I do now? Is this a known issue?

    I had this same problem with what's app.  There is a new update for the app on the app store which is compatible with ios8.  Update the app, or delete it and re-add it.  I found a lot of apps weren't compliant with ios8, but after updating everything worked fine.

  • Slow startup after Mavericks update in MacBook Pro (MD102HN/A)

    After the Mavericks update, my MacBook seems to lag at startup, starts really slowly. Especially when the lock screen is about to appear and the Apple logo kind of slides upwards. Does anyone else face the same problem or is it just me? The slide always lags!

    Remove all items in System Preferences > Users & Groups > Login Items
    Same for    /Library/StartupItems
    Then restart your Mac to test.
    And check to make sure there's enough free disk space.
    Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage
    Make sure there's at least 15% free disk space. Less can slow your Mac down.
    If nothing above helped, the startup disk may need repairing ...
    Launch Disk Utility located in HD > Applications > Utillities
    Select the startup disk on the left then select the First Aid tab.
    Click:  Verify Disk  (not Verify Disk Permissions)
    If DU reports errors, restart your Mac while holding down the Command + R keys. From there you should be able to access the built in utilities in OS X Recovery to repair the startup disk.
    Make sure to back up all important data first before using OS X Recovery.

  • Macbook slow at startup After Update

    Hi I am new to Mac's well I just updated to 10.4.9 and now my startup speed is slower than before also when opening app's. Well I emptied the Caches in home Library, Hd Library and system Library. But it still keep's being slow. I think I will do Disc Utility the on the Macbook Disc.
    Please help

    Hi Macbook91.
    Whatever the problem is here, I don’t see how you’re going to solve it clearing the caches. The purpose of caches is precisely to speed up the access to commonly used data...
    It may sometimes be necessary to delete some caches while troubleshooting a specific problem because they may become corrupt, but caches shouldn’t be deleted as part of regular maintenance procedures.
