Performance upgrade op SQL VM

Hi,
I did setup a new VM for SQL.  Software vendor installed SQL2017 on it and their application. Clients are complaining about performance and speed of the application.
Is there a way i can approve the performance of the virtual machine or with other words the performance of the application.  by adding more VCPU ? more Memory ? other settings ??
Any help would be welcome.

This is the Host i use :
HP DL380 G10 - 2 processors XeonSilver 4110 -  RAM 144Gb -  SAS disks 10K
RAID5 -> Host
RAID6 -> VM’s

These are the VM settings for the (VM) SQL-server
1 Virtual CPU
32Gb RAM (not dynamic)
Disksize is 1Tb

Regards,

Jo

Server 2016 nested virtualization second level OS limitation?

Setup would be this:

Level 0: Hypervisor.

Level 1: Host Server 2016 named "Host", and the first guest with Server 2016 named "Guest-Level-1" and "Set-VMProcessor -VMName Name-ExposeVirtualizationExtensions $true" activated for this level 1 guest.

Level 2: Now which OS are supported as Level-2 virtual machines within "Guest-Level-1"? Is this limited to Server 2016 or Windows 10 (at least 1607) as well?

Aside from supported: Any experience whether those Level 2 guests can be Server 2012 (R2) or Windows 8 (.1) or even Windows 7?

Why is my vhdx taking up so much space?

I have built a CentOs 7 guest VM in Hyper-V as Gen1 with two drives, both dynamically expanding drives.

I have loaded about 170 GB of data into one of the drives, but on disk on the host, it is taking up 410 GB. What is going on?

This is in the guest:

$ df -h | grep ‘sdb1|Used’
Filesystem                     Size  Used Avail Use% Mounted on
/dev/sdb1                      504G  168G  311G  36% /var/lib/data

This is from the host:

    Directory: D:VHDs

Mode                LastWriteTime         Length Name

New host lost internet access – VM on host do have access.

Hi

Starting up with Hyper-V I made a image of my server.

I then activated Hyper-V on the server.
(The server had 2 external IP adresses).

I then removed one of these IPs from the host NIC.
I started up the VM and gave it the removed IP.

Now the VM does respond to the IP and works as expected. It can be reached from outside.
I can also ping the host IP from outside, but the host does not have Internet access.

ipconfig /all show the external IP as (Duplicate) and 169.254.190.177 as (Perferred) on the same Hyper-V Virtual Ethernet Adapter NIC. In the NIC settin for IP4 I only see the external IP.

How do I get the host to respond on the external IP?

When i delete a checkpoint, virtual server crashed and also the host crashed

Hello

I have a server 2012 R2 host with hyper-v.

In the hyper-v i have 1 virtual machine that is 1.6 TB in a SSD disk of 2TB (1.81 TB) which left me with 168GB available.

i did checkpoint to the virtual machine, and the checkpoint growth a lot. So from 168 GB free space, it turned to 40 GB free space. i then  , wanted to remove the checkpoint. and the minute i deleted the checkpoint, the virtual server crashed and so the
host was also crashed. when the host turn on and start up, i got blue screens and crashed again. then i got heart attack, cause its a production server… after i myself recoverd , i try to start up with Last Known good configuration, and somehow a miracale
happend and the server turn on and startup correctly. now again i have 168 GB free space. and no checkpoints of course.

After a few days, i tried to install backup software, which did somekind of snapshot before the backup started, and the server crashed again with blue screens. again i started the server with Last known good configuration and now it’s fine.

My question is why the checkpoint get the server crashed ? is it because of low disk space ? maybe hard disk fault ?

I also can tell that in the event viewer i see sometimes (every couple of days) some disk warning - The IO operation at logical block address 0x1b241d60 for Disk 0 (PDO name: DeviceIdeIdeDeviceP0T0L0-0) was retried.

 Please assist.
