Hyper-V guest boots to recovery console after shutdown

I experience the following scenario:
After a hyper-V host (W2008R2 Ent.) is restarted, the guest VMs (W2008R2 Ent.) boot randomly to recovery console. This means some of the VMs boot correctly into Windows server environment while others boot into recovery console. Whether the recovery console
is booted does not depend on the particular VM i.e. on one occasion a given VM boots correctly next it boots into recovery. Most frequently this happens after updates have been installed and the hyper-v server restarted.
Neither the system log or the application log reveals anything out of ordinary, shutdown procedure is executed in a standard manner without any problems. The same about the bootup after hitting cancel in recovery console. There is no mention about entering
the recovery console in the log.
Can you please guide me through troubleshooting. I suspected that the hyper-v host shuts down before the guests are all off but in this case I would hope to see a notification from the system that the previous shutdown was unexpected which does not happen.

Hi ,
This issue might be due to the forced restart after updating installed successfully .
As a workaround , I would suggest you to enable No auto-restart with logged on users for scheduled automatic updates installations :

Also , you may try to set the automatic stop action to save in VM settings to check the result .
Hope it helps

Mountain Lion only boots into Recovery mode after using iCould lock

Hi everyone!
I have searched the forums for hours now, but I can't seen to find an answer to my question, so I'd like to ask it.
Recently my system partition failed due to frequent kernel panics caused by a cable in the screen I think. The kernel panics still occur, but I don't know what to do with them.
I managed to save my files and reinstall my osx, which is Snow Leopard (the disc came with the computer). Then I wanted to install my purchased copy of Lion through Appstore, but it said it's no longer available in my country and I couldn't download it again.
Then I decided to buy a copy of Mountain Lion which I tried to install. I managed to do it, and I tried to explore my new operation system.
I tried the iCloud app as well, including the Lock. It locked the computer, and rebooted, but ever since I couldn't unlock it.
When it asks for the password I enter it and it accepts it, but doesn't unlock, only lets me into Recovery mode. Now I reinstalled the whole thing over again and when the Mountain Lion install finishes, it only boots into the Recovery HD without asking.
So if I reboot my computer, no matter what I do it only boots into Recovery Mode.
Please help!!
Mike

I was afraid the Apple Store wasn't going to be an option.
Based on your previous post, I was under the impression you could download Mountain Lion, but when you installed it, it locked up again. Not true?
I don't know how to remove it. You can try contacting Apple support through the link below to see if they can help you get this unlocked.

Are the kernal panics new since all this happened?
Here is some information about kernal panics.
Kernel Panics - About
Kernel Panics - Avoiding and Eliminating
Kernel Panics FAQ
Kernel Panics FAQ (2)
Kernel Panics - Understanding and Debugging
The articles discuss where kernal panic reports are filed. After you have a kernal panic, copy the report and post it here. Please copy and paste rather than using a screen shot. There are several people who can read them and they can suggest what to do next. Reading kernal panic reports isn't something I've totally figured out yet.

Can't access the recovery console after installing the Windows 7 RC

Hi all,
I recently installed the Windows 7 RC to give it a go but I've found that it kills my battery life so I decided to go back to vista, however when I press the blue button on start up to access the recovery console I just get a screen that asks me if I want to enter the BIOS or choose another boot location... I used the upgrade option in Windows 7 so I don't see how I could have deleted the partition with the recovery console...
Is it posible for me to restore my tablet to it's factory settings?

The install of Win 7 removes the TVT boot manager applet and sets the master boot record to Win 7 partition only.
The Lenovo supported method of restoring your preload would be thru the use of Recovery CD's.
You might be able to change the bootable partition from the win 7 partition to the recovery partition, thru some
3rd party apps.

Booting in Recovery HD after clean install of Lion

I just deleted my hard drive to do a clean install of Lion, but after I downloaded Lion from the recovery HD, my Macbook Pro will only boot in Recovery HD, and not in the Lion install manager as i was expecting.
When I try to select the Macintosh HD from the boot menu, it is not there, although I can see that I have 6 GB used space on the hard drive. (so I assume that is Lion)

Not sure what you are doing but you need at least 15GBs of space to download and install Lion.
You say you Deleted your hard drive? You can't delete the drive, it is a physical thing. You can remove the Macintosh HD partition using Disk Utility and that is what I think you did. You have to Re-Create that partition to install Lion on.
With Disk Utility open from the Recovery HD go to the Partition tab and highlight the partition box and click the Plus sign as the bottom. Or select One partition from the drop down list. Name it Macintosh HD and use Mac Extended (Journaled) as the format. Click Apply.
Then go back and select Install OS X. Then Continue.

My MacBook won't boot into recovery mode after new hard drive installation. Please help!

I just installed a new hard drive. On boot it keeps on going to the flashing folder with a question mark inside.
I was able to format the new hard drive but am unable to boot into recovery mode to install the operating system over the air.
When I hold down Command -R it keeps on taking me to the flashing folder.
Please help!

A new hard drive doesn't have a recovery partition. It's totally blank.You're going to need either your original install discs or a Snow Leopard retail disc from which partition, format and install OS X.

Booting in Recovery mode After Update

I have an Early 2013 MacbookPro Retina with Maverick and I was having issues connecting to my Wireless Router so I decided to Reboot the laptop.
After it rebooted, the Mac logo on the Grey Screen showed up with a progress bar. The progress bar took a while to complete and then computer shutted down.
I then pressed the power button to turn it back on and it started in recovery mode. Using the DiskUtility I see the disk, I see the Partition but cannot mount it. I ran the DiskUtility's Verify and it tells me to Repair the Disk. I click Repair the Disk and it tells me the disk could not be repaired and I should to backup the maximum number of files possible and then format and reinstall the OS. But for the sake of God, it cannot even mount the partition! How am I suppose to backup anything?
I'm so ****** off, I lost a week of work. Spent the week working away of the office and the Time Machine Backup is a week old.
*** Apple!
Please someone tell me that there is something I can do to recover my work!

Here's what I'd try:
Hook up an external drive. Boot to the Recovery partition. Partition and format the external drive, then install OS X on it. When that's done, boot while holding down the Option key and choose the external drive. From there, see if you can now read the internal drive and get your files off. Once you have what you need, you can reformat the internal.

How to boot service/recovery partition after a Windows 7 install

Does anyone knows how to restore the boot feature of the service / recovery partition ?
I did a Windows 7 RC install and it seems to have disable booting to the recovery partition. I can see that both the SERVICEV003 and Lenovo partition are still there.
Thanks.

Broken screen, erased main disk, cannot boot to Recovery Mode to reinstall OS X

I am using a MacBook Air from around 2010, not really sure what version of the OS was on it prior to erasing. The screen is broken so I have to either duplicate the screen or use clamshell mode to see anything. When booting in Recovery Mode by holding Command + R, the only option is to use clamshell mode with an external monitor because otherwise only a gray screen is shown.
My issue is a result of erasing the main disk while in Recovery Mode and then shutting down the MacBook. I turned the computer back on assuming I could use clamshell and Recovery Mode to reinstall the OS but unfortunately this isn't working and I can't get anything to display on the external monitor.
I cannot use Target Disk Mode from another Mac because there is no FireWire port and there is also no Ethernet port.
This leads me to these questions in trying to figure out how to reinstall OS X:
- Is it not possible to boot in Recovery Mode after erasing the main disk?
- Is it not possible to use clamshell mode after erasing the main disk?
I have also tried booting while holding Command + Option + R to use Internet Recovery or booting while holding just Option, there was still nothing to be displayed on the external monitor after closing the lid to switch to clamshell mode.
I'm stuck, any suggestions would be greatly appreciated.
MacBook Air, Mac OS X (10.4.8)

FYI:
I have tried booting into Single User Mode, using fsck to repair permissions, but to no avail. However in the Single User Mode I did notice something unusual. When trying to reboot using the command 'exit', a long list of errors came out.
Most were Library/Extensions/... .kext is not authentic; omitting from prelinked kernel.
Some errors were ...: No such file or directory
And afterwards the errors were stuck there and no reboot occurred. I also couldn't type anything.

2008 r2 hyper-v guest with static IP always looses network connectivity after every restart - no problem with DHCP

Hello,
We are running 2008 R2 domain with one physical DC and other running in VM on Hyper-V host (2008 R2 Standard). The host has 4 NICs and is configured to use one physical NIC for itself (management) and the hyper-v guest is configured to use another dedicated/physical
NIC (through microsoft virtual switch) just for itself.
I noticed that after setting the hyper-v guest with a static IP address all works fine only until guest restart. When the guest boots up the IP address is still configured correctly in IPv4 properties, but there is no network connectivity at all and in fact
the guest shows running APIPA config in ipconfig /all output. That situation continues until I remove the virtual NIC from hyper-v guest, remove the virtual switch from dedicated NIC on host and then reconfigure it (using same settings as they were). very
annoying.
For time being I switched the virtual DC (problematic hyper-v guest) to a DHCP IP and configured DHCP server (running on physical DC machine, not on hyper-v host) to store a reservation for the hyper-v guest so it always gets the same "static"
IP configuration.
Is there some kind of a problem/bug with using static IP on (2008 R2) hyper-v guests? is there a hotfix for static IP config in hyper-v guest environment?
both 2008 R2 OSes (host and guest) are up to date with all updates (synced with Microsoft, not WSUS).

OK, I'm not at the office now, but took my time to test out the restart scenarios on problematic virtual guest remotely.
No dice, same as it was, everything works fine after guest has IP configured in DHCP mode (IP reservation of 192.168.1.5 for specific MAC address) and it doesn't work after restart in static IP mode (same address, works before restart of guest).
I also took "arp -a" outputs at each step from host server and that was always saying there is only a single host (192.168.1.5 = VDC = problematic virtual guest) assigned to that IP address and always with same MAC, so that pretty much rules out
ARP/MAC troubles and no issues with switches/routers getting spoofed. Problem is most likely with the virtual guest (WS2008R2) or within the host running same OS.
Here are outputs:

Throughout the testing, the hyper-v host IP configuration and IPconfig output was always staying same.

On Monday I will install more test guests in Hyper-V host (WS2008R2), in variety of flavors like 7x64, 8.1x64, ws2012r2, and see if they show similar problems with static IP configuration when utilizing a dedicated NIC from host server.
Don't get me wrong, I can live with virtual DC running on DHCP IP reservation (which is based on MAC), because the virtual DC pretty much requires a physical PDC (hosting also DHCP in my network) to be present for safety reasons ... however I prefer a static
IP configuration on all servers, hence my question and surprise why it doesn't work.

Windows server 2012 R2 DC (Hyper-V Guest OS) DNS error event id 4013 in log after installing KB2975719 and/or KB2995388

Hi,
I just freshly installed a guest OS Windows 2012R2 on a Hyper-V 2012R2 server. Installed lots of updates and did many reboots, after that I installed the AD component. Couple of days later I'm having trouble with a RemoteDesktop server joining the domain.
After some research I see in the DNS log the following message:

I did a restore from an earlier point, recreated the ActiveDirectory, but messages still coming in DNS log. I started from scratch with installing a new guest OS Windows 2012R2, directly after loging in first time, I installed AD component, and
give the server a reboot. and got the events below that looks normal:
Type: Warning
User: N/A
Computer: Fileserver.domain.com

The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed. The DNS server service cannot start until the initial synchronization is complete because critical DNS
data might not yet be replicated onto this domain controller. If events in the AD DS event log indicate that there is a problem with DNS name resolution, consider adding the IP address of another DNS server for this domain to the DNS server list in the Internet
Protocol properties of this computer. This event will be logged every two minutes until AD DS has signaled that the initial synchronization has successfully completed.

After that I create snapshots after installing every (10-15 updates), reboot, check dns log, and almost the last update, the KB2975719 and/or

Any idea?
Kind regards,

Hi Steven,
Would you please tell us that is the event 4013 logged continuously?
If this event is only logged after reboot or restart DNS service, then it is a normal behavior.
As we can see Event 4, which indicates that the DNS zones have been loaded successfully.
In addition, if Event IDs 4523 and 4524 are being logged after the Event 4013, then there is no problem with DNS service.
More information for you:

I'm doing some lab environment testing with Storagecraft Shadowprotect backup for a client. We are backing up Hyper-V guest operating systems. For busines continuity, the backups can be spun up to Oracle VirtualBox VMs in the event of disaster,
but the backups can also be restored via their Headstart Restore tool to a VHD or VHDX. Right now, I'm using a Windows 7 x64 VM for the test backup.
Here is my current problem (for the moment, forget about the Storagecraft part). Once the VM is restored, I've lost access to the keyboard via Hyper-V console (the mouse does work, this allowed me to run the
on-screen keyboard so I could see what was going on, and then test via RDP). I can RDP to the VM and use the keyboard and mouse. I have a few unknown devices in the Device Manager that weren't there before. The processor also has a
"splat" (yellow triangle, exclamation point).
At this point, I don't want to troubleshoot the "why" (that will be another step), but I do wish to find out how to reinstall the necessary drivers to get the system working. I tried reinstalling the Hyper-V Integration Services, but the
VM says they are already installed. These can't be uninstalled via Control Panel. I've tried mounting the Hyper-V Integration Services and doing a right-click "Repair" using the msi in the Support folder (both the x86 and the amd64);
when I do this, it reports that the action is only valid for products that are currently installed. The same happens for an uninstall.
Does anyone have any ideas how I can get keyboard support back?
Everyone gets everything he wants. Me, I wanted to be a sysadmin. And for my sins --they made me one.

Hi Sir,
>> I have a few unknown devices in the Device Manager that weren't there before. The processor

For troubleshooting , please try to use Windows server backup to backup/restore VM to narrow it down .
In addition please try to use installation media to perform "in-place upgrade" to "repair"
that VM .

PXE Boot a Hyper V Guest - Not receiving a DHCP IP Address

Hello Everyone,
I am trying to PXE boot a Hyper V guest, but am not getting a DHCP IP Address. Eventually the DHCP query times out and loads into the guest OS I have manually installed. See the PXE Boot Screen below. When in the installed guest OS, I do receive
a DHCP IP address as shown below. I am utilizing the Legacy Network Driver. I don't think it is related to VLAN identifier, but tried with/without and still no go. Any ideas what could be preventing this? Please let me know.
PXE Boot Screen:
CLIENT MAC ADDR: 00 15 5D F2 99 0C GUID: B366BBA1-D503-4D64-A77E-77474F3A2193
DHCP.........-
PXE-E51: No DHCP or proxyDHCP offers were received.
DHCP IPCONFIG in Guest OS:
Ethernet adapter Local Area Connection:
   Connection-specific DNS Suffix . : mywork.com
   IPv4 Address. . . . . . . . . . . : 10.242.242.251
   Subnet Mask . . . . . . . . . . . : 255.255.255.128
   Default Gateway . . . . . . . . . : 10.242.242.129
Thanks,

Hi Ron,
A solution is provided in this thread. You may need to have a look on the steps below:
• PXE-E51: No DHCP or proxyDHCP offers were received.
The client did not receive any valid DHCP, BOOTP or proxyDHCP offers. To resolve this issue, check each of the following network configuration items:
DHCP services are not available on the network to which the PXE-enabled NIC is connected.
A DHCP proxy or IP helper address is not configured for the subnet on which the PXE client is connected.
The switch port connected to the PXE NIC is running Spanning Tree Protocol, EtherChannel Protocol, or Port Aggregation Protocol and is thus not activated immediately when a link is detected. This forces the DHCP request from the PXE client to timeout.
DHCP is available on the network, but PXE is not.
The network cable is not attached to the PXE-enabled NIC on the target server.

Can't access windows or dv6t-3000 recovery partition after unix boot menu removal.

I have a dv6t-3000 laptop running Win 7 Home premium 64 bit; my son had put a unix partition on it. Since I tried to bypass the unix boot menu using MBR (the idea of my brother, the IT professional) the laptop just gives a unix error message at startup (error: no such partition. grub rescue> _) If I hit escape while starting up I get the startup menu including F11 System Recovery but Fn+F11 (it's a laptop) does nothing and hitting the F11 key itself just sends me back to the Unix error message.
Shamefully I never made a set of recovery discs; how can I boot into Recovery? Would the Recovery USB flash disk utility work, or screw things up further? Any help would be appreciated!

Sadly, I must recommend that you purchase a recovery disc set.
Playing around with Linux ( probably ReiserFS) and MBR does bad things to the Windows boot sector. One option is to reinstall GRUB. The second option is If your brother can find a Windows 7 64-bit repair disc for you, then you may be able to repair the boot sector. That should make the original Windows 7 installation useable again. Otherwise you will need the recovery disk set to restore all functionality, including the recovery partition and the F11 recovery manager access.
Sorry to bear bad news.

Guest domain obp alias changed after upgrade to 1.0.3

Hello all,
Recently upgraded from 1.0.1 to 1.0.3 (and firmware to 6.6.5) using the procedure at http://blogs.sun.com/jbeloro/entry/upgrading_from_ldoms_1_0. I found that my boot-device setting on all guest domains no longer worked. They were set to "boot-device=vdisk" however after the upgrade to 1.0.3 vdisk was no longer a valid device alias in the obp of the guest domain. The other device aliases (vdisk0, disk) were there and they worked fine. Anyone else seen this? Solution was simply to change the boot-device setting but I'm curious on the "why". Details below.

I don't have a pre upgrade devalias output but I do have the output from an eeprom command...

Thanks.

I think this because with LDoms 1.0.3, devalias are automatically created using names
you used to define your vdisk. So after the upgrade, devalias have probably been
wiped out and replaced with the ones automatically generated.
