Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

hi,

any one know if there is any Free Windows server to test he Windows server in hyper-V VM?

and anyway to have a test Azure to learn how to opeation Azure SQL server? or Azure interface is just a portal to CREATE Azure SQL and we only use local SSMS to maintainence and admin that?

Hyper-V Cluster-management IP-adress changes mac-adress when switched from one to the the other host in the cluster. We've got Veeam running on one of the virtual servers in a hyper-v cluster and we see that Veeam is unable to access the list of virtual servers through cluster management, when it resides on the host that does NOT currently host the cluster-IP (and thus provide its mac-adress). this manifests as a network error (IP not reachable) and we're assuming this is the case since the switch involved has this IP-adress assosiated with a different mac-adress.

Is there any way to ensure that the cluster-management-IP retains its mac-adress even if it's moved from one host to another?

Using Citrix with an existing VDI

I registered a Windows 10 Desktop at this location:
https://www.infosaic.com/

But, when I logged in, I found the Windows 10 Desktop was displayed inside a Web Browser. This is not what I had in mind...

If I have an IP address to my Infosaic VDI, can I then use Citrix to enable me to have a Full Screen version of this Windows 10 Desktop?

Thanks

Adding a Windows 10 Hosted VDI on AWS

I thought this would be simple on AWS. But, when I try and "Launch an Instance" and look through the various Windows options, I see only Windows Server?

Isn't a Windows 10 Desktop VDI considered an Instance?

What am I missing?

Thanks

does vmotion require input from the admin , i believe once a VM is under resource crunch , it auto moves from 1 esxi host to another - do i sound correct

when we use vstorage motion - does it require any input from admin

how do i deploy ovf template is it same as creating vm template?

does DRS plays a part in vmotion?

I have two images residing on the same VM Ware Workstation Pro host. I can ping both machines from each other. However when I go into SSMS and try to connect one to another I get the message that the server cannot be found. What do I need to do to conect these two SQL instances. I need to create a linked server from one to another. Right now there is no domain. Is it a question of setting the DNS addresses?

Recently upgraded to the new version of vm workstation 15.5. Now my power usage on my workstations are very high and cause my computer to blue screen and reboot. I use to run to workstation at a time now I can barely run one. Have anyone seen this or have a fix?

Can you please let me know what tools or means or how to check below.


Check the health of all Hosts and VM objects in vCenter.  Are there any active alarms in vCenter?  

Are all vCenter plug-ins functioning properly?

If any Host Hardware issues?  Alarms, bad memory, power supply or capacity issues?

if  any resource bottlenecks?  Memory, CPU, Disk, Network?  
 is the load properly distributed?
if running out of resources anywhere?  LUNs with low disk space, etc.  
Check for Firmware updates on Host hardware- can we  use update manager


Check for ESX Patches
Check for VM Patches
Check VMware Tools version
Run scripts to identify the existence of VMs with snapshots and follow up to see if they are still needed.
Have you schmoozed with your Storage Admins lately?  A good idea since you cannot get very far without them.

I have an AD joined the server with applications. I want to build another identical server.
What is the best way to do this? The new server will be joining to the domain with a new name and SID. I would appreciate it if you could help me with this.

I have two Exchange servers that are failing to backup using Veeam. The error is:

Exchange servers (both of them with the same error:

Failed to prepare guest for hot backup. Error: RPC function call failed. Function name: ISsnapshot in progress) Target machine x.x.x.x. RPC error, The RPC server is unavailable. Code 1722. Error: RPC function call failed. Function name: (ISSnapshotinprogress). Target machine x.x.x.x. RPC error. The ROC server is unavaialble. Code 1722


I ran vssadmin list writers, none of the writers are in an error state.



Would this issue be related to firewall ports not being accessible on the Exchange server? And if so which ones should I create an exception for?

Tried the following:

I rebooted the server.

Ran vssadmin list writers - VSS NTDS was stable and was not in an error state.

Ran job but it failed with the same error.

Ran vssadmin list writers - the VSS NTDS was in error.

Ran diskpart  - automount - the aotomatic mounting of the drives is enabled.

Deleted .bak files in the registry in the following reg area:  HKLM\Software\Microsoft\Windows NT\CurrentVersion\ProfileList

Rebooted the server.

Ran vssadmin list writers - NTDS VSS was stable and was not in an error state.

Re-ran job and it failed with the same error

Any assistance would be great.

Need .NET Framework VDI / VM Preconfigured

Are there VDI's where Visual Studio / SQL Server / Source Code Management

come pre-installed? That would save me some potential aggravation...

Thanks

I am trying to create a Windows 10 Pro VM on a 2019 Std server.  The ISO I am using is from the VLSC (SW_DVD9_Win_Pro_10_1903.1_64BIT_English_Pro_Ent_EDU_N_MLF_X22-14064)  I do not want to use 1909 due to search issues.  I have the VM setup so that the OS installs on startup.  The error message I get is "Windows could not complete the installation.  To install Windows on this computer, restart the installation"

I have deleted and recreated the VM, downloaded a new ISO and both receive the same message.

Hi, we are looking at some further guidance on setting up failover clustering on two Windows Servers 2019 connecting to a HP MSA2052 SAN.

•      The servers are DL380 Gen10 with 8 NIC ports.
•      The current wiring connections are shown below (we will redo this for redundancy on the controllers)
•      The MSA 2052 has two controllers, each controller has two connections on different subnets connecting to the two servers via one switch with two vlans. (Layer 2 switch)
•      The servers connect to a different production switch for normal data traffic.
•      The iScsi initiators and MPIO have been configured and both servers can see the storage volumes.
•      The Servers can both ping all four ip addresses on the 172.16.*.* subnets, the nics on the 172.16.*.* subnets, don’t have a default gateway configured as per guides we have been reading. Jumbo frames are set up on the iSCSI NICS and switch.
•      The servers are pingable via their full domain name from other devices on the 10.226.*.* production network. The servers are in the correct Server OU.
•      The servers currently don’t have a network setup for a heartbeat and migration.
•      The servers also have Teamed NICs setup for a virtual switch within HyperV manager

The failover clustering invalidate configuration wizard test is failing on:
At least two independent paths to storage target are recommended for each Test Disk
Test Disk 0 from node Server1 (shows FQDN) has 1 usable path to storage target
Test Disk 0 from node Server2 (shows FQDN)…

Hi,

I can no longer access my VMware vcenter inventory. When I log into the web client, I see this message:

Could not connect to one or more vCenter Server systems:
https://server name:443/sdk

If I try to connect using the vSphere client I get the attached message.

I can login to the Microsoft Server with the vcenter server, and I can SSH to alle the ESXi servers but not the vSphere server.

I'm running an older VMware version 5.1.0 Build 1115182.

How can I fix this?

Thanks,
Ronnie

Please suggest a Virtual Desktop Infrastructure (VDI) Platform

Please suggest a few good brands I should consider...

I expect to use Windows 10 and the .NET Framework set of Dev Tools.

I need a VDI for some development work and expect to also have some offshore developers also help. I presume one VDI per developer.

Make any sense? (This only MAY work with free Open Source software)

Anyway, I need some good branding VDI options. Free is better, but key features may make a small fee worth it.

Thanks

I have just had a product update go very very bad on a VM.

I am restoring from the backup from before started doing anything right now.

The VM had two drives C and D.

D is just a data drive.

My question is. Will I be able to use the .VHD file for the secondary drive? Or will I need to restore from a backup also.

I mean it depends what the upgrade did however I don't think the data on this drive was changed.

Points of My Scenario
1. I am admin for our VMware infrastructure: vCenter Server 5.5 on ESXi 5.5 cluster
2. Microsoft has asked me to update the BIOS for one of the Windows VMs - not the ESXi host
3. I upgraded the hardware version of the VM (from version 8 to version 9)
4. This hardware version upgrade did not change the BIOS version of the VM (Note: I used Windows' built-in msinfo32 to get BIOS version).
5. Info: The VM's "BIOS version/Date" - as reported by msinfo32.exe - is "Phoenix Technologies LTD 6.00 9/17/2015"

QUESTION: How do I upgrade the BIOS of a Windows VM (Server 2012 R2) hosted by an ESXi 5.5 server?

Hi VMware Experts

We have in our production an old VSAN hybrid cluster

So we got a new server and I build all-flash VSAN cluster but I don’t configure EVC on this cluster

Then I started to migrate some VMs from the old cluster to the new one  it works very well

Now I want to bring one VM backup and I don’t want to power off this VM and I got an error about EVC

What can do in this case or what options I have to fix this issue

please check the attached files

Hi vmware Experts

i used to use VSAN default storage policy for our VMs

now i created a new policy with to tolerate 2 physical hosts failure

then i start to edit the storage policy for some VMs

my question

how can i see the progress of the changes on this VMs

i mean when i apply the new policy  VSAN should create another replica for the Vdisks for this VM i want to see the progress

and i want to know such action will put huge load on VSAN itself or not

Hello All;
(Windows 2016 Server running SQL Server 2019 Cluster installation)

I have run into an issue and I am at a complete loss as to what to do about it.
The only other option is to delete the VM and create a new one and re-do the process and see if it will work then.

OK.
On a Virtual Machine.
I have SQL Server 2019 installed as a cluster.
Currently, there is only ONE server running in this test run.

Connecting to the server through SSMS 18.4
From my laptop to the server, it fails every time. Error 26
I have done the following.

(On the VM Server)
Made sure all SQL items in the Services, are in fact running and they are from the get-go.
Open Firewall for programs: SQLBrowser and SQLServer. (Also for good measure, I created two more rules for 1433 and 1434)
For SQL Server Config Manager - Enabled all items, TCP/IP, set on port 1433 for both the IP Addresses shown.
(Actually, there are IP Addresses in the TCP/IP config, that I have NO idea what the heck they are, or how they got in there???)

I checked the DC for entries in DNS, and all IP addresses are entered.
Both for the two NICs and the Cluster assigned IP.


Installed SSMS 18.4 on the VM Server, and it connected to it, without an issue.
I also checked once I launched SSMS to make sure it was set up to allow connections, and it was by default.
It just will not connect through the network.
Now, this is NOT my first time working with a VM Machine with SQL Server and connecting with …
