Hyper-v 2012R2 can't start VM's registry access issues?

After adding hyper-v role to 2012r2 all was working fine until last week when VM's stopped and now I can no longer start any of the VM's or new one that I create.
After much searching it seemed to be a permissions issue but none of the suggested solutions worked. I uninstalled Hyper-V role and added it again, no errors were reported in this process. I then started Hyper-V manager with process monitor tracing VMMS.exe
and VMWP.exe and I see registryopenkey error with keys not found and/or access errors and file access errors.
This happens at Hyper-v manager startup as well as when I try start VM's but the only error in the event log is a error 3040 Can not initialize VM.
Here is a snip of the process monitor for Hyper-V Manager startup:

Am at a total loss, any help appreciated.

Hi KiranaSven,
The event 3040 usually caused by the following reason, please check the environment in which the start virtual machine operation was being attempted, including:
1. Access and permissions to the configuration file, memory file and all image files
2. Prior error messages in the event log
3. Available RAM on the system
4. Configuration settings
5. Disk space for the memory file and any expanding virtual hard disks

Hyper-V VM can't start with VHD attached, error 0x80070422

Hi,
i'm in a big trouble with Hyper-V on a Windows 2008 R2 server. Hardware is a HP Proliant DL360 G7. Role are DC, Hyper-V (yes, i know it's not recommended), AV client is Kaspersky Endpoint Security 10.2, and everything was working fine for more than a year.
Here is the full story, with the first part of problem i resolved.
First part:
I had problems with HP NIC (nc382i) when trying to update drivers to last version, and with HP Network Config Utility. I updated NIC drivers, then reboot, and i had the BSOD on boot, even in safe mode. So i had a look to minidump with debbugger, to find
reasons, and it seems the ksecdd.sys driver was the culprit (cryptographic kernel driver), but didn't get why, unless Kasperksy had to to something with it...anyway, i was able to boot by using the last good know configuration, and then I
removed the virtual switch on Hyper-V, dissolve HP network team (4 NICS), update drivers, then HP NCU, then tried to add a new Hyper-V virtual switch, all of these of course with VM stopped, and with autostart disabled on host reboot. I had BSOD only in normal
mode, no more on safe mode, so i used again last good known configuration, removed Kaspersky Endpoint Security, HP team, and virtual swith, used all drivers which were old working versions, made again HP team, virtual switch, and everything went fine, at last!
Boot with no errors, network was up and usable, all services were fine. Maybe it isn't important, but the only thing i realised is that network takes long to be up on reboot...
Now, second part with actual problems: i tried to start VM in Hyper-V...and i had the famous errors:
Microsoft Emulated IDE Controller (Instance ID {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}): Failed to Power on with Error 'The service cannot be started, either because it is disabled
or because it has no enabled devices associated with it.' (0x80070422).
And events ID 12140, 12010 and 12030
No matter what VM i tried to boot, it won't. Even if i try to create a new one, same issue.
I had a look everywhere to find solutions, so i tried with no luck :
- Change registry key to let correct a timing issue with FSDepends.sys and with
VHDMP.sys ("Start" REG_DWORD at "0" instead of "3" in "HKLM\SYSTEM\CurrentControlSet\Services\FsDepends")
then reboot
- Verify all access to registry, files, etc. with procmon utility to find a security problem
- Uninstall ARCServer BrightStor Backup, clean in safe mode any trace of Kaspersky with
kavremover utility
- Reverse to old HP BIOS which i know is working on others servers with same configuration
- Verify again access to file and registry while trying to boot VM with
procmon utility
- Removed Hyper-v role, then after reboot, install all same HP drivers for NICs, HP NCU, which are working on others servers, then reinstall Hyper-V role, create new VM...
- Verified many times files integrity with sfc (online and offline...)
Finally, i was able to boot a VM, only if i remove attached VHD, and i use only a DVD on IDE Controller, for booting for example on a Windows Server ISO. If i use an SCSI Controller, even without a VHD attached to it, i have other error:
Microsoft Synthetic SCSI Controller (Instance ID {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}): Failed to Power on with Error 'Insufficient Memory' (0x8007000E).
So i think the problem is with kernel driver, vhdmp.sys, or something like
vdvroot.sys, but i don't know how to correct this, and i'm in a dead end...is someone know for example what means the
0x80070422 error ? How can i verify kernel driver integrity?...
Any suggestion will be greatly apreciated, thanks!

Hi,
That error occur often is the Unknown Device installed which was related to vhdparser, maybe the AV soft change the vhdparser.
Please try to changed the startup value for FsDependes from 3 to 0 and also uninstalled the Unknown Device which was related to vhdparser from device manager.
If you are using the pass-through disk please install the following hotfix:
"0x0000000A" Stop error on a Windows Server 2008 R2-based or Windows Server 2012-based Hyper-V server that has many pass-through disks

I can't start DHCP Service or access Xserve share points from pc's

When I try to start the service I get an error message:
CANNOTSTART_SERVICEERR
I'm not sure what I'm looking for here.
I have SMB services running and I can see and access files on pc's and macs on the network from macs, but I can't access the Xserve shares from pc's.
Do SMB and DHCP services work together in some way?
This weekend we had a power outage and I had to repropogate permissions on all share points so that certain macs could read and write.
The Xserve restarted like it should but is there something I need to set to keep permissions after a power outage?
I have the server set up as a standalone server and it's the only one on the network. And I have permissions set so that everyone has read/write permissions.
I'm using a cable modem to a Linksys router to multiple switches.
Any ideas?
Thanks

Best practice configuration for SQL 2014 to achieve HA when hosted on Hyper-V 2012R2 cluster

Hi,
I've had a hunt around but so far I've not found a conclusive answer to my question. I am currently moving from a SQL 2008R2 (physical tin) failover cluster to a virtual environment build on Hyper-V 2012R2. I am building everything with SQL 2014
SP1.
I want to achieve the same level of high availability that I currently have and at the same time make sure that I can replicate (DR) data offsite (Azure) in the future. I have two options with SQL which are clustered instance (basically the same as
I have now) or AlwaysOn Availability Groups for database level HA.
I am unsure which is the best method to use when the SQL nodes are highly available guests on Hyper-V, trying to imagine how the guests will all move around in the case of a host server failure is a bit mind boggling to say the least.
I am leaning towards a instance failover but I would appreciate any input/advice etc.
Thanks
Rob

Hi Rob,
To start with I will not be installing SQL Server 2014 with SP1, as SP1 has bugs and Microsoft has disabled its download. See reference: http://www.eweek.com/database/microsoft-halts-sql-server-2014-sp1-downloads.html
With regards, I would go for AlwaysOn Availability Groups configuration, because it has several benefits:
You will get same amount of high availability you normally get with native cluster configuration, if you use AlwaysOn configuration. However, AlwaysOn configuration provides more granular high availability, and fail-over are invisible to the application,
if you using Availability Group listener to connect to server.
You can offload read-only workloads to secondary replica.
You can perform transaction log backups on secondary replica.
Reduce production downtime during patching or other planned work on the server.
So in short, you should use AlwaysOn configuration.

Are Hyper-V 2012R2 checkpoints Application data consistent? How does it use now VSS during checkpoints creation?

Are Hyper-V 2012R2 checkpoints Application data consistent? How does it now use VSS during checkpoints creation?
I read the article http://www.aidanfinn.com/?p=15759 that now WS2012 R2 Hyper-V changed how it performs backups.
That is unofficial info. I can't find any info about that in msdn, but that is critical.That is about data integrity.
Is this true?
Does this mean that we may not use VSS in Hyper V server backup application any more? Will Hyper-V 2012R2 host (WM is running) when i am creating a checkpoint,
call VSS to only flush VSS Writers during this process for target child VM to make application data crash consistent state? And the volume shadow copy wn't be used? Only vhdx +avhdx witch will merged later, right?

There are a couple levels to this.
If VSS is there, VSS is used (just as before). But there is a bit more happening around it than simply placing the VM in a saved state.
However, if VSS is not there (in the VM) then the behavior is slightly different (this is really to support Linux VMs that don't support VSS) - and still achieve a good VM backup.
In another blog post I see it described this way:
Online backup for Linux VMs – even though there’s no VSS support in Linux, the Microsoft guys have managed to find a way to create consistent backups of running Linux VMs, by doing what’s essentially called a “filesystem freeze” by briefly stopping
all disk I/O inside the VM until the host creates a VSS snapshot of the VM on the host (thus getting a file-consistent backup with zero downtime) – once the snapshot is done, disk I/O is resumed and then the actual file copy process starts
Flemming shows the process here:
http://flemmingriis.com/changes-in-hyper-v-backup-in-2012-r2/
If you are calling VSS to perform a backup - nothing has changed. The only thing that has changed is the 'how it happens' , not the 'what you get' and 'how you call it'
This way if you call VSS to perform a backup - you get a good one, no matter the OS in the VM, nor its support for VSS.

Hyper-V(2012R2) Backup with Checkpoints(Snapshot) and Export - What to consider ?

good evening
Today I recognized that a VM Snapshot (excuse
a checkpoint) can be exported with
Windows Server 2012R2.
The subsequent import resulted in a
functional VM in saved state.
Question: What concerns a backup to a deduplicated Drive
with the following PowerShell
commands?
# Backup running VM's on a hyper-v 2012R2
# (p) by steini'14
$rootPath = "I:\VMBackup"
#create Backup Path of the Day
$path = new-item -ItemType Directory -Path "$rootPath\$(Get-Date -f yy_MM_dd_HH-mm)"
# Do Snapshot and export and "Merge!" Snapshot/Checkpoint for each vm on this host.
foreach ($vm in get-vm){
    write-host "Start: $($vm.Name)"
    $snap = $vm |checkpoint-vm -SnapshotName "BackupJob $(Get-Date -f yy_MM_dd_HH-mm)" -Passthru
    $snap | Export-VMSnapshot -Path $Path.FullName
    $snap | Remove-VMSnapshot
Start-DedupJob -Volume $path.Root -Type Optimization -Wait
#PrepareDisk:
#Add-WindowsFeature -name FS-Data-Deduplication
#Enable-DedupVolume I:
#Set-DedupVolume g: -MinimumFileAgeDays 0
#Start-DedupJob -Volume i: -Type Optimization -Wait

Hi ,
I am not familiar with powershell .
#create Backup Path of the Day
$path = new-item -ItemType Directory -Path "$rootPath\$(Get-Date -f yy_MM_dd_HH-mm)"
I think it will create a new folder to store the export image when the script start to run .
Also the disk space for storing these image is a factor what you can think of .

How to manage a Hyper-V 2012R2 Host from Windows 7?

AFAIK This is the official Hyper-V Manager for Windows 7: http://www.microsoft.com/en-us/download/details.aspx?id=7887 it explicitly lists Hyper-V versions up to 2008R2,
there is no mention of 2012 or 2012R2, and from trying to connect to my new Hyper-V 2012R2 I can confirm that it doesn't want to work.
From reading the docs on Hyper-V 2012/2012R2 remote management I've come to the conclusion that its only possible with Windows 8+ or Server 2012+ , but it cannot be used to manage Hyper-V 2008/2008R2...
Someone please tell me that this is just one big mistake on my part and that the product owner for Hyper-V at Microsoft is not this stupid...

Hi,
On Windows7 platform you can manage Hyper-V server under the 2008r2 versions.

Applies to:
Oracle OLAP - Version: 10.1 to 11.1
This problem can occur on any platform.
Symptoms
- We have an AW maintenance / refresh script or procedure that contains BuildType="BACKGROUND", so that the AW maintenance task will be sent to the Oracle Job queue.
- When we execute the AW maintenance / refresh script or procedure, we do not get any errors in the foreground, the script/procedure has been executed successfully.
- However when we look into the build/refresh log (see <Note 351688.1> for details) we see that the maintenance/refresh task failed with:
13:29:39 Failed to Submit a Job to Build(Refresh) Analytic Workspace <schema>.<AW Name>.
13:29:39 ***Error Occured in BUILD_DRIVER
- In the generated SQL trace for the session of the user who launches the AW build/refresh script or procedure, we see that ORA-27486 insufficient privileges error occurred at creation of the job.
We see from the relevant bit of the SQL trace that err=27486 occured while executing the #20 statement which is 'begin DBMS_SCHEDULER.CREATE_JOB ...', and the statement is parsed and tried to be executed as user having uid=91:
PARSING IN CURSOR #20 len=118 dep=2 uid=91 oct=47 lid=91 tim=1176987702199571

begin
DBMS_SCHEDULER.CREATE_JOB(:1, 'plsql_block', :2, 0, null, null, null,
'DEFAULT_JOB_CLASS', true, true, :3); end;
END OF STMT
PARSE

1176987702325167
ERROR #20:err=27486 tim=465202984
Cause
User who tries to create a job (executes DBMS_SCHEDULER.CREATE_JOB() procedure) does not have the sufficient privileges.
Solution
1. Identify the user under which the job is supposed to be created. This user is not necessarily the same as the user who launched AW build/refresh script or procedure. Get the corresponding username from one of the %_USERS views e.g. from ALL_USERS.
e.g.
SELECT user_id,username FROM all_users WHERE user_id=91;
2. Identify the system privileges currently assigned to the user by connecting as the user whom the privileges need to be determined, and execute:
SELECT * FROM SESSION_PRIVS ORDER BY PRIVILEGE;
3. Ensure that the CREATE JOB privilege is listed.
The CREATE JOB privilege can be granted in various ways to a user:
- via role OLAP_USER or via role OLAP_DBA (see view ROLE_SYS_PRIVS for what privs are assigned to a role):
GRANT OLAP_USER TO <username>;
- explicitly
GRANT CREATE JOB TO <username>;

Click here and follow the instructions. You may need to completely remove and reinstall iTunes and all related components, or run the process multiple times; this won't normally affect its library, but that should be backed up anyway.
