Hi all.

Have a 2012 R2 server core with 10GB C drive. Using Hyper-V I added an additional 5GB. Problem I have, how do I extend the drive? I can't access 'Disk Management' using remote MMC. I had previous question in EE and thought we'd fixed it, but no. I can do anything else remotely except access that MMC console, so I can't simply extend the volume. This isn't a question about not getting to MMC, I've had it with that and given up, I put that down to crappy core.
I need a command that lets me see the available space. I try Get-Volume but it only shows the 10GB. And I need the command that will expand the disk to use up the other 5GB.

Thanks for looking

My home computer is a Dell XPS 9560, running Win10 Pro.
I want to install a Win7 VM, to install a Point of Sale program on, so I can use to learn the software. Unfortunately, no Win7 drivers are available for my laptop, or would I be able to use the Win10 ones? What about making a VM from a real POS terminal & import it as a VM? Would that be a better option?

Hello,

Is there something I can do when I receive this error (op operating system was loaded) in Hyper-V


I do not know if the system I have imaged was UEFI or not. I also do not understand the SCSI disk term, since it is a regular SATA of which I created the VHD.

We have a pfSense 2.3.4 with LAN, WAN, DMZ.
In DMZ subnet, we set up a Network Load Balancing cluster with two web servers in a 2012R2 Hyper-V environment. Their IP are:
DMZ port: 10.10.2.1
Server1:     10.10.2.21
Server2:     10.10.2.22
NLB Cluster: 10.10.2.100
NLB mode: multicast

Inside the DMZ subnet, each host can ping other hosts without a problem. The only stumbling block is, from pfSense, I can NOT ping the NLB cluster even I am able to ping all other servers in DMZ subnet. As the result, the cluster is useless.

In pfSense, I can see there is no ARP table entry for this cluster IP. How come?

I bet the Hyper-V NLB cluster is not new and am wondering if anyone ran into this issue before. Please help.

We have a Hyper V VM that is a server 2012R2 box. 64-bit with 4 GB of RAM.

It crashed from what I believe is a memory leak. Not sure how or the best way to monitor for this.

Ideas or experience?

Thanks

Hello,

I've inherited a HP server running 2 VM's.   The CPU appears very limited.  I'm wondering if the CPU resource could be better allocated and therefore the whole machine Host+Guests will be a little happier until the whole system can be upgraded.
IMO the server is under spec'd and should be replaced.

Host Details
ProLiant ML350p Gen8
CPU: Xeon CPU E5-2609  Appears as 4 cores  (HT not available on this CPU) (single CPU fitted, 2nd spare socket)
RAM: 64GB  (was 32GB until last week)
DISK: Several RAID-1  SAS 15K  
OS:  SERVER 2012 (R1) Desktop with Hyper-V role

Guest 1 Details
CPU: 1vCPU
RAM: 8GB
OS:  SERVER 2012 (R1) - Domain Controller

Guest 2 Details
CPU: 3vCPU
RAM: 32GB
OS:  SERVER 2012 (R1) - File Server, RDS Server (10 concurrent clients), SQL DB, LOB applications

Some screenshots attached.


Questions

Is the assigned 3vCPU and 1vCPU about the best compromise for the current hardware?

Is there anything within the Processor or NUMA configuration that could change to "improve" performance of the overall system ?

This physical CPU only has 4 cores.  This CPU was under spec'd from purchase.  Fitting a 2nd CPU now could help.

Thanks for any input

I am running a Hyper-V VM on my windows server 2012 r2 server.  When I attempt to run the Event viewer or windows backup on the vm, I get an error saying "MMC could not create the snap-in;  The snap-in might not have been installed correctly.  Name: Windows Server Backup".  I of course googled it and have tried several "Fixes" but none have seemed to do the trick.

I have tried a registry key delete, replace a machine.cfg file, re-install gpedit.

Other thoughts or ideas?

Can a Windows Server 2012 Hyper-V VM be exported and then imported on another Windows 2012 Hyper-V host machine?  Or can the VHD be used on a new VM on a different host machine?

I have a newly built windows 2012 R2 server with all updates installed that has been configured as a clustered Hyper-V server.  Everything is installed and passed validation.  When I go to create a new vm, I supply all the required information, name, memory, disk size, network, where to store the vhd and where to pull the OS from.  It builds the vm and leaves it in the off state.  When I start it, it starts to load the OS, I get the progress bar with files loading, then I get the error:

EXITING:  unable to find root\cimv2 service -2147217402

I've read through multiple threads and cannot pin down a fix to this error.  I find lots of threads relating to XP, Win7, nothing relating to W2k12 or this specific error.   Anyone know what the number refers to?   I checked the event logs and nothing there.     Several post seem to relate this to WMI.  I checked the repository and it states that it is fine.     I've been on this for several days and have gotten no where.

On a single open license of Server 2016 Standard, with a single processor, does the licensing give me the permission to install the FULL Hyper-V host (with the GUI) plus the ability to install 2 VM's on top of that host?
Thank you

Hyper-V installed on Windows 2012 r2. HP 360 G9 64 GB, 2 TB raid 10 disks. I have installed 2 vms; 1 Domain controller with SQL standard 2016 and 1 Remote desktop server +gateway. For both servers 1 cpu was added. I want to add more vcpus or more cores to them. Is this possible without getting errors, or problems with blue screens?

How much do i need?
