I have a vm on hyper-v 2012R2 (not update) with a
backup checkpoint that I can not delete. The checkpoint was created by veeam
during backup. There is no opting in the GUI to manually delete the checkpoint.
I ran the backup again and it was succesfull however it did not delete the
checkpoint. What can I do? the checkpoint is growing quite rapidlly

Hello all
We configured one Windows 2012 Datacenter core with 64 GB RAM and teh server has 12 cores (2 CPU X 6 core). Four virtual servers are required to be configured with 3 cores & 16 GB of RAM for each (dedicated cores and memory for each Virtual server). For the host server how much memory & core is required, how we can calclulate the requirements
Thanks in advance

We ran into a problem with duplicate dynamic MACs in our 2008 R2 Hyper-V cluster. We restarted a server and when it came up, it had a MAC that another VM had on another Hyper-v host in the cluster. To get out of the problem, I shut the machine down and assigned the machine a static MAC.
After further reading, it appears that I probably should have just restarted the machine and let it pick up a new dynamic MAC from the pool on the Hyper-V host where it resided. It still makes me wonder why another machine had the same dynamically assigned MAC and neither of the VMs wanted to change.
Has anyone struggled with this before?

Dear All,
I need to setup a hyper-v failover cluster, but I am stuck at how to setup the networking part of it. All servers have Four-4 NICs. Following is desirable:
Team (2 NICS) for Cluster/Heartbeat/Live Migration/CSV/I/O
Team (2 NICS) Virtual Machines with different VLANs
How to achieved such a configuration?
What changes are required on the network switch?
What changes are required on the physical NICs on servers?
What changes are required on the teamed adapters?
Is creating two-2 teams; and using the second team for Virtual Switches and assigning VLAN IDs a solution?
Would I be needing to create multiple external virtual switches for all the VLANs?
thanks in advance.
I am planning a Direct Access deployment. The Direct Access servers have to be domain joined. Yes or No?
The direct Access servers will be virtual machines on Hyper V in a DMZ (2 nodes) Stand alone hosts.
Do i need to join the Hosts to the domain?
Can I join the direct access servers to the domain as VMs on hosts that are in a work group.
Please advise
good evening

This is the opposite of all the other networking issues I have seen with Hyper-V- anyone run into this?
I am running Hyper-V on a Server Core installation, and have had the same issue when I used Server 2012R2 as when I used Server 2008R2 on the same server as a virtual host. The server is an HP ProLiant DL360 Gen8 with 2x 8-core processors, 32 GB RAM. The VM is sized and configured to stay within 1 NUMA node. It uses a single port of the 4-port HP/Broadcom 331 NIC, with all the TCP LSO settings disable at the switch, host, and guest, same with the power management settings. We have ProxyARP on the network, so I have set the ArpRetryCount key to 0.
I have seen it happening with and without SR-IOV enabled. The guest OS is an RDS server, so for the sake of our CAL's it has to stay at Server 2008R2. I have set up a HOSTS file to mitigate this problem, as it seems to be a DNS issue- Here's what happens:
The first time I visit a resource, the server will timeout. An example not in our HOSTS file does this consistently: If I go to https://mail.mydomain.com/OutlookWebAccess, it spins for a couple of minutes before timing out. I hit refresh and the page loads immediately. This server is colocated in-house, as is the mailserver. I'd say it is a DNS issue at some level, but I'd like to know what level it is- Is it just timing out trying to cache the DNS request, or is there a performance issue with a DNS server on the network? (All of our DNS is AD-integrated running on DC's).
Here is where I'm seeing this:
Internet Explorer- described above
Salient Interactive Miner- at the login screen, it searches for a database and times out. If I go to the setup and enter the IP address, it still times out. It will not find the database server until I quit and restart the program. If this is the same issue, it would obviously not be a DNS problem.
I DON'T see it in GP9 connecting to a datasource
Prior to setting up the HOSTS file, I saw this in Windows Explorer connecting to network shares on the same LAN segment.
This appears to only happen to the Hyper-V guest OS. As a best practice, whenever Windows Update runs, I update the Integration Components.
I have the bindings properly ordered on the guest VM, with the network adapter the goes to the physical NIC first, and IPv4 ordered before IPv6.
All updates are isntalled, and the firmware is at it's latest revision.
Any ideas?
Hi,
I am unable to create an external virtual switch on server 2012 R2. I have two Broadcom NICS bridged on a DC fully functional now. I can install Hyper-V but the option is grayed out to create an external switch. I try binding it to the network bridge, connecting my two NICS and it makes no difference.
Am I correct in assuming that I cannot use Hyper-V on this server if the two NICS are bridged?
I am preparing to upgrade my Server 2008 R2 Standard Hyper-V Host to Server 2012 R2 Standard with Hyper-V
All of my VHD's etc reside on the 2nd volume, therefore my install will just go to volume 1.
Will moving my SBS and secondary DC from Hyper-V 2008 R2 to 2012 R2 cause any issues?
I won't need to actually copy the VHD's (which I've heard is risky), but it will install the new Integration Services and I fear it could cause Domain issues.
thanks in advance,

Hi
We found many articles saying we need to enable Hyper Threading / Logical Processors to improve the performance with Hyper V - virtual servers and some other articles saying it should be disabled.
We are looking forward to get advise, most of our servers are Dell blade M 610 with 2 X CPUs with either 8 / 12 cores
Thansk in advance

Hi Hyper V Guru,
I am trying to do inspect on the disk of my VM by right clicking the VM-> select settings -> Select Hard Drive -> and click on the Inspect. However I am encountering the error message: "An Error occurred attempting to connect to the virtual disk management service on computer 'localhost'. Cannot connect to the RPC service on computer 'localhost'. make sure your RPC service is running. what is actually the issue that happen?
Second query: how do I accurately confirm that my VM has no snapshot?
Third Query: if my disk is fixed vhd disk, is it possible to expand it? what are the best procedures and steps of doing this task? what I should notice properly before expanding? will there be any risk of expanding VHD? as this is our production exchange server and very critical, I am really worry of doing this.
Thanks for your attention.
Regards,
Henry
Hi!
I have been testing AD disaster recovery with few domain controllers (Server 2012R2), running on Server 2012R2 and Hyper-V. Everything OK unless I try to log in to Domain Services Recovery Mode.
After username&passwd screen goes all black and nothing happens. Every time, every server (tested this with 3 different HP workstations, one HP ML350G6 server and one laptop). Hyper-V virtual machines tested both gen1 and gen2.
With 2008R2 Hyper-V and same domain controller on it everything works fine. This makes systemstate restore bit more difficult.
Am I missing something or is it just a bug? Googling didn't help this time.
Let me start by saying, I've followed just about every guide I can find on delegation and permissions and virtually everything works just fine except for this...
I created a VM using Server 2012 R2 Hyper-V. That server was created on, stored on and exported to a Server 2012 R2 File Server, all using my workstation (Windows 8.1) to remotely manage the Hyper-V server. That should be proof that delegation works perfectly fine (being able to create a VM and export it on the SMB share remotely, right?)
My user account, workstation computer account, and the Hyper-V server account all have full rights to the SMB share (NTFS and Share Permissions). To clarify further, my user account is a domain admin.
However, when I go to import the exact same machine that I JUST exported successfully I get the error: Hyper-V did not find virtual machines to import from location '\\FS01\Hyper-V\Exports\Server2012R2\' - The folder '\\FS01\Hyper-V\Exports\Server2012R2\' could not be found. You might not have permission to access it.
Here are some outputs to show that I've, hopefully, configured everything correctly:
PS C:\Windows\system32> Get-SmbDelegation FS01
WS
HV02
PS C:\Windows\system32> Get-SmbDelegation HV02
WS
WS:
Get-WSManCredSSP
The machine is configured to allow delegating fresh credentials to the following target(s): wsman/*.domain.local
HV02:
Invoke-Command -ComputerName HV02 -ScriptBlock {Get-WSManCredSSP}
The machine is configured to allow delegating fresh credentials to the following target(s): wsman/FS01.domain.local
This computer is configured to receive credentials from a remote client computer.
FS01:
Invoke-Command -ComputerName FS01 -ScriptBlock {Get-WSManCredSSP}
The machine is not configured to allow delegating fresh credentials.
This computer is configured to receive credentials from a remote client computer.
I should also not that it works fine if I remote desktop to the HV02 server and do the import.
Hi,
When trying to initiate hyper-v replication from the main server i'm getting this error in the event logs.
---
Hyper-V failed to enable replication for virtual machine 'RECADemo': A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file. (0x800B0101). (Virtual Machine ID 561591B6-567C-...)

I'm using certificate based auth and cert is installed/recognized on both machines.
Please help.
Thanks,

I am little confused over how to setup the cluster to accommodate different VLANs inside the Cluster hosts. I have 4 NICs. I also want to separate traffic through VLANs for intracluster communication, live migration, virtualization, External, Perimeter, etc.
How can this be achieved?
Will it work by forming two teams out of 4 nics and distributing different vlans among them? if so, would appreciate if someone could share the steps.
also, what changes would be required on the network end. Thanks.
Hello All,
When a raw LUN is added as a CSV disk in Failover CLuster manager, does it require format ? If not, how is it managed by the disk system?
