Hi,
Is there a way to integrate to the Hypervisor level of Hyper-V.
As it exist in VMware products and others.
For example:
Integrating to the networking layer to monitor the network traffic that goes in/out of VMs throw the Hypervisor level?
for integration of networking product like that:

Very weird.
Hyper-V Manager 2012R2, when left open, keeps allocating more and more memory. I've seen it grow until over 2.5 Gbytes !!! Closing it then wil make it release the memory slowly, and when done it crashes...
Anyone else seen this ?
Hi,
My system clock is incorrect by 3 minutes. I can 100% blame it on HyperV time sync.
I am running Windows 2012 r2 for domain contollers and HyperV. I have 3 domain controllers. Two on HyperV and one physical. One of the HyperV domain controller has the PDC role and sync time.
I have added this registry on all DC
reg add HKLM\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\VMICTimeProvider /v Enabled /t reg_dword /d 0
I see that the key is correct on the servers.
and I have added new NTP server
w32tm /config /manualpeerlist:"0.pool.ntp.org 1.pool.ntp.org" /syncfromflags:MANUAL
and
C:\Windows\system32>w32tm /query /source
1.pool.ntp.org
The time is syncing correct from 1.pool.ntp.org but HyperV changes this right back Again.
How can I fix this?
brgds.

Hi,
We are now designing a solution related to storage pool creation from ISCSI LUN. In this situation, we created 3 x 3TB iscsi LUN on SAN storage and presented to the Hyper-V cluster. We can create storage pool which contains all 3TB iSCSI disks, so that storage pool is 9TB in total, and then a 9TB virtual disk from the storage pool to form a CSV. However, we found that storage spaces only supported using SAS storage. May I know if the existing design is a certified design or not? Thanks!
Reference:
https://technet.microsoft.com/en-us/library/hh831739.aspx
Claiming that the storage spaces needs:
Serial ATA (SATA) or Serial Attached SCSI (SAS) connected disks, optionally in a just-a-bunch-of-disks (JBOD) enclosure
Hey guys, quick question. I have a system running Server 2012 and I've got 3 Hard Drives attached to the system:
100GB SSD (OS Only)
500GB SSD (DATA)
2TB USB 3.0 Drive (DATA)
2TB RAID 0 7200RPM Drives (UNUSED-AVAILABLE)
If I have 5 VMs and I want them to use a single share, is there a benefit of using 5 separate iSCSI disks (1 dedicated to each VM) over a single Virtual Hard Drive?
Quick Background, I've got 5 VMS, each running an instance of music broadcasting software. This software uses a SQL db that I set up on it's on VM and it pulls it's music library to wherever I tell it too. I'm basically moving from the VHD partition I created for each server to the iSCSI method. Saving a lot of space because I can now delete those music vhd partitions and have it pull directly from the 3.0 drive where I have much more space to spare.
Any recommendations? I can use my 3.0 drive strictly as a backup device and move the iSCSI files on the same SSD as the Hyper-V data, the RAID 0 array or leave it how it is or keep the VHD method that I currently have?
We are about to migrate from VMware to Hyper-V. We are having a debate on whether to use Genteration 1 or 2 disk. I have been reading there are some issues - Gen2 only suppost Serve 2012r2 and windows 8. also there are some issues with SCVMM.
It would be intresting to hear some views on this topic and maybe some up to date links on this topic based on people experiences
Best regards, Wayne
Firstly, the only goal for this setup is to have a quick way to have all VMs up and running in the case of a hardware failure on either host.
Is it possible to have VMs 1,2, and 3 running on host A while replicating to host B and have VMs 4, 5, and 6 running on host B and replicating to host A? In other words, does each host need to be either Primary or Secondary or can each host be both?
Hi,
The questions seems to be simple: I`d like to change location of bin file, which is created by hyper-v on the same location as vhdx. I know that there is a gui for that in Settings > Management > smart paging file location and checkpoint file location, but after write those data to xml, bin file still creates on vhdx drive.
This forces us to leave from hyper-v to vsphere because in vsphere "it works". I read many many times that suggests to increase a lun, which is rather a joke. Will anyone pay for extra terabytes of SLC enterprise SSDs fully redundant lun (3par) because of hyper-v bug?
So, is there a way to change location of those files? But tested and confirmed it works.

Hi,
I started to carry out a NIC Firmware upgrade on one node of a Hyper-V 2012 R2 Cluster but was warned that a TPM chip was detected, etc.
I can see the option to Suspend Bitlocker on the C:\ drive but couldn't see a similar option for the CSV drives. Do I have to suspend it for the CSV drives or just the C:\ before continuing with the firmware update?
Cheers for now

I've recently replaced a PERC H310 RAID controller with a PERC H710p RAID controller on a Dell PowerEdge R820 running Windows Server 2012 R2 and started experiencing this problem. Everything I've investigated so far doesn't point to this being the issue, but wanted to mention it in case someone encountered something similar.
We were having terrible disk performance until the RAID card was swapped out, and as a precaution I moved all existing VMs off of this Hyper-V host server. Once everything was back up and running, I began a live migration back to the affected host server and it blue screened. Tried again and same result. I then tried copying the VM images manually through a UNC share and hit the same problem. It doesn't always happen at the same time during the copy. I've had blue screens happen 4-5 GB into a transfer, and 200 GB into a transfer.
I've updated the RAID controller driver and firmware to the latest available from Dell, and have installed the latest BIOS and chipset driver. The server has Broadcom 5720 series NICs, updated with the latest drivers and firmware provided by Dell. All Windows/Microsoft updates have been applied.
After all these firmware/driver updates the blue screens still kept occurring during network transfers. All the minidumps show a 0x133 DPC_watchdog_violation error, where the DPC time allotment is 500 ticks and the blue screens happening at 501 ticks. Running the minidumps through Windows Debugger pointed to tcpip.sys, netio.sys, and vmswitch.sys initially. Since tcpip.sys and netio.sys aren't typically the issue, I looked around for anything related to vmswitch.sys being the problem.
I disabled the Hyper-V vSwitch in the OS and did a transfer 100% successfully, with the traffic running through the same NIC the vSwitch was configured to use. Once I re-enabled the vSwitch and transferred more files......the blue screen came back.
In researching, I found reports of this issue when a Hyper-V host was using NIC Teaming. We don't have any of the NICs on this server teamed, but I figured it wouldn't hurt to apply the latest hotfix that addressed the issue.3031598 - even after applying it I was getting more bluescreens. I couldn't find a way to use the updated vmswitch.sys that came with the hotfix (6.3.9600.17714); I tried deleting and recreating the vSwitch, but the old driver (6.3.9600.16384) is what gets applied and searching the OS for an updated driver doesn't turn up anything. I also can't find any info online about manually updating the driver after applying a hotfix.
I'm fairly certain vmswitch.sys is the issue, but I don't know where to go from here. Are there any NIC or vSwitch settings I can adjust to help with this? Has anyone encountered a similar issue? Can anyone lend a hand in diagnosing this issue? I found some good resources on debugging and troubleshooting this issue further (2 URLs below), but this has gone from "this is a good learning experience" to "this needs to get done" in the few weeks I've been troubleshooting.

All the minidump's from every time this has happened can be viewed here: http://1drv.ms/1R6CfAO.
Here are all the suspects from those minidumps:
Probably caused by : vmswitch.sys ( vmswitch!VmsPlcApplyPolicy+26d )Hi,
Whats the best way to monitor Hyper-V guest performance.
We got a system spread across application servers, sharepoint servers and SQL servers on various Hyper-V hosts performing very poorly and need to identify the culprit.
Hi,
I am trying to create a guest cluster using shared vhdx's as the means of storage.
But for some unknown reason I can't see my disks.
Although I can see them when I run a validation test. But it's telling me that the disk bus type does not support clustering.
Please see this screenshot.
Do you have any ideas?
Please can you help.
Thanks
I'm trying to set up HyperV Manager (6.1.7601.17514) on a x64 Win7 machine, connecting to a 6.1.7600 server (Hyper-V core server?) The Win7 is itself a VM, freshly minted for the sole purpose of providing HV Management to the existing server. I have a physical Win7 system on which Manager is running fine, but that machine is destined for retirement soon -- so I'm trying to replace it with a Win7 VM (hosted on a Win 8.1 system.)
I'm using HVRemote 1.08 and all machines involved are in the same workgroup; i.e., no domains involved at all. I'm using the same logon credentials on the Win7 VM that I'm using on the old Win7 machine so I didn't think I'd need to add another user on the server; nevertheless after receiving the root\cimv2 error I went ahead and tried it. Got an "error" saying there was already a user by that name.
So, I'm at a loss as to how to proceed at this point. Running (from the Win7 VM)HVRemote /show /target:<servername> shows me the failure to connect to root\cimv2 namespace. Name resolution does seem to be working in both directions.
I'd appreciate any pointers on how to fix or troubleshoot this issue.
Thanks in advance,
Bill

Hello folks.
I've been bashing my head on this one for a while... I have a 5 host hyper-v cluster 2012 R2 with all the patches and using latest ProLiant support pack. 4port 1gb nic's. All host share this setup 2 nic teamed (sw. independent\dynamic) for management\live migration\csv traffic (created 3 separate teamnic's with different vlans). 2 nic team (sw. independent\dynamic) for a VM Switch (no vlan configured here). Everything works fine on 4 hosts, while the last one seem to be bugged. Not more then 1 VM on this host may have network connectivity. I've installed latest HP Broadcom drivers (16.8.0.4, they claim to have fixed VMQ issues), I've tried disabling and enabling VMQ (same results), I've modified baseprocessornumber and maxprocessors for NIC's, I've applied the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VMSMP\Parameters\BelowTenGigVmqEnabled with value "2" to disable VMQ, I've used Disable-NetAdapterVMQ and Set-NetAdapterAdvancedProperty "NIC NAME" -DisplayName "Virtual machine Queues" -DisplayValue "Disabled".
Same thing. After I make a change, all the VM's start working for like 10 seconds, then every vm except for one loses network... Could you please give me any other piece of advice... I've been troubleshooting this for over a week.
ps. Everything works fine on other hosts...
Thanks in advance

Hi,
need your Help :-)...
I have:
2x WS2012R2 Hyper-V Host, both in Domain, Live Migration enabled
WS2012R2 VM as Guest with 2 SCSI Harddrives (Gen 2 VM) connected as vhdx Files.
One vhdx is direct in Folder of the VM, secound i have on other Harddrive (single drive, ntfs formated).
When i do Live Migrate i see that the first vhdx is copied but when it comes to the second vhdx migrate stops with: Error General access denied (0x80070005). Harddrive and second vhdx both have read,write access for the Hyper-V SID.
Do i remove second vhdx live migration works. Do i move second vhdx in the Folder of the first one live migration also works.

Hello,
As I understand the best method of excluding page file and have a good planned failover, is to initially exclude the page file on a separate VHDX, then shut down system, and copy the VHDX with the page file and attach to replica before booting.
1. Is this the best method of getting a replica VM up and running without errors with the page file?
2. Is it ok to leave the page file off completely, and let the replica re-create temporary page file when it boots up, thinking in terms of File Servers, and SQL servers.
Thank you
Robert
Hi,
When I break and then re-enable replication, its doing a full initial copy
1. Is it possible to break and re-enable replication without doing a full initial copy?
Thank you

Hi,
my Scenario:
Primary site - Hyper-V Cluster Windows Server 2012 R2
Replica site - Hyper-V Host Windows Server 2012 R2, same IP subnet
several VMs with SQL 2012 SP1 and SQL 2005/2008, SQL on same VHDs and on different VHDs (Set-VMReplication -VMName <vm-name> -EnableWriteOrderPreservationAcrossDisks 1)
VM Integration Services: 6.3.9600.16384
doing Application Consistent Recovery Points on the SQL-VMs which seems to running well...BUT if you look at the Application-Log inside the SQL-VMs I get following errror every time a Application Consistent Recovery Point is running:
SQLVDI: Loc=SignalAbort. Desc=Client initiates abort. ErrorCode=(0). Process=2644. Thread=7212. Client. Instance=. VD=Global\{3346955E-6377-4992-BA65-5DB64EFA8399}1_SQLVDIMemoryName_0
BACKUP failed to complete the command BACKUP DATABASE model. Check the backup application log for detailed messages.
BackupVirtualDeviceFile::SendFileInfoBegin: failure on backup device '{3346955E-6377-4992-BA65-5DB64EFA8399}1'. Operating system error 995(error not found).
Same error on all my SQL-VMs.
VSS Backup (within the host) of my SQL-VMs with Windows Server Backup works as expected without any Errors.
So I believe this is an Hyper-V Replica issue not an SQL issue!
I did the same tests on a completely different Hyper-V Replica Environment without Hyper-V Cluster --> same errors
any ideas....
Thanks for any replies...christian
