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.

I'm running Hyper V on my Win 10 Pro laptop & have a Win7 VM running there for learning my way around some POS software. I'd like to be able to use a CC swipe with it & see plenty of articles out there on adding a USB HD to a VM, but not so much something like a CC swipe.
The one I'm currently trying is an IDRA-335133B-DL. I found one article that recommended connecting to the VM via RDP, but it's still not showing up.
Any suggestions?

For the past weej I have been racking my brain trying to fix this issue. We have a Hyper-V virtual machine Windows Server 2008 Standard machine that recently started requesting activation. When we try to reactivate we get :

Error Code 0x80070426 - Service Cant be Started.

I was able to identify the services by researching the error code as SLUI Service, and a service it is dependent on Software Licensing. It seems without these services running the server cannot authenticate the license. When we try to restart these services we get:

Error on restart - 0x80070005 - Access is Denied.
AND
An unauthorized change was made to Winodws 0xc0020012

I have tried:
- Running Chkdsk - Fixed errors but no change to activation.
- Pushed into Last Known Configuration. No change.
- Attempted using cmd to start services - Received System Error 5 code
- Verified license is still good with Microsoft
- Attempted Integration Service Upgrade - Get Directory invalid error

So I am stuck an hoping someone has had this experience or a way to fix it.

With NSX you can use Flow Monitoring to see all the conversations hitting a particular VM. Is there any way I can see this information for traffic hitting the load balancer VIP? Or even better see it at the packet level?

hi i have a project for you :
Configuring a Virtual Network.
creat a virtual networking components that VMware Workstation provides.
For this solution we hard that our solutions is to make 10 VM for one service :
1 Vm for Dns
1 Vm for DHCP
1 Vm for LDAP
1 Vm for Samba
1 Vm for Syslog
1 Vm for NTP
1 Vm for NPM

all these VM with Ip static.

I have Mac Address and IP, for each VM, it's yet done.

In fact is Building a simple server to provide DNS, DHCP, NTP  DHCP
LDAP
Samba
Syslog
NTP
NPM
to support  different appli and share this VM for 20 developpers

at the end, we'll deploy app with ansible, that we had roles yet written.
Thanks

going to be a paid project,

Hello,
I want to move VMs from one Vcenter (5.5) to another (5.5).
The vcenters are in different sites. Each site has its own subnet.
The two sites are in transitive trust and same domain.

Any ideas?

Thank you

I will be replacing a physical file storage server (currently has 650Gbs of data), and also a virtual machine Exchange 2010 server (25 Mailboxes)
I want to acquire a new Hyper-V host  and upgrade and virtualize both servers.  We do not have money for a SAN or anything like that so all VMs will reside on local disks.  The file storage VM guest OS drive will be configured with 120Gbs fixed disk, and then 1.2Tb dedicated for data that is also fixed storage.  I am just wondering if adding a virtual hard disk with 1.2Tb works well, etc.  I mean I have not worked with VMs with disks larger than 500Gbs in total.  

I've do not believe its a good idea to have the user data reside on the guest OS either.  It's nice just dealing with one disk per VM, but in a physical server that's a no-no, so I would think this also applies in a virtual application.

The new Exchange server 2016 or 2019 will most likely all reside on the guest OS drive.  I've been running Exchange 2010 with this configuration on a 2012 Hyper-V host for many years now with minimal issue.  

I just want to make sure adding a virtual hard disk to a VM that is greater than equal to or greater than 1.2Tb is reasonable and works without issue.  

Any suggestions/recommendations?

We have an old ERP solution that only runs on a 32-bit server. Currently it is running on an old local Windows Server 2003 R2 with Service Pack 2.

I believe Windows Server 2008 was the last "server" product that Microsoft released that was available as 32-bit. As a test, I built a new server VM running 2008 but my ERP solution didn't like it at all. So I deleted the VM. (It was still 32-bit so other than the fact that 2003 is EOL, there was really no benefit anyway)

I'm not really interested in upgrading the server that the ERP solution is running on because (1) 32-bit is limited to 4 gb ram and (2) as I mentioned, the 2008 instance was a bust.

What I AM interested in doing, is moving this VM from my local server to a VPS or a cloud hosted solution.

Web hosting companies like A2 Hosting or Rackspace, etc ... they DO offer VPS hosting but they come pre-loaded with Server 2012, which means it's 64-bit, which means my ERP solution won't run on it. And since these are not the types of hosting plans where I can BYOOS (bring your own OS), it's not a solution for me.

Is there a way for me to take my VM (prebuilt, running Windows Server 2003 and my ERP already installed) and just "upload" it somewhere?

I don't know much about Azure but from my limited research, it appears you CAN spin up your own Azure server instance and during the deployment, choose your own OS.  The problem is, since Win Server 2003 is EOL, it's not one of the OS options that you get in the …

Hi
I have a ESXi Host V 6 running with 4 virtual servers.

One of the servers will not start as it says the allocated disk size is full. I cannot even restart it in Safe Mode.
I have tried to increase the disk size as the VM Client says there is still 175Gb of unallocated space. But if i try and extend the disk it says it is full.
These are not thin installs
How do i get onto the Virtual Server to delete some files?

We receive this alert multiple times per day, for multiple VMs .  We have been in contact with both Nimble and VMware and neither of them seem to be able to tell us why or fix it.  Any suggestions as to what could be causing this?  

"Failed to create vCenter snapshot associated with the volume collection "collection" for virtual machine "server" due to failure to quiesce the virtual machine. See vSphere Client to get details on the failure of the snapshot task for this VM."

NFR key for Veeam Agent for Linux

NFR key for Veeam Agent for Linux

Veeam is happy to provide a free NFR license for one year.  It allows for the non‑production use and valid for five workstations and two servers. Veeam Agent for Linux is a simple backup tool for your Linux installations, both on‑premises and in the public cloud.

Hi,

First, we have only the Essentials Plus license, so vMotion is not an option...
Also we migrate from a VMFS 5 datastore to a VMFS 6 datastore.  I thought that would no be a problem since the VM is switched off and dead during the migration...

We have followed VMWare's suggestions when migrating VCSA between datastore without using vMotion:
Close all connected clients
Shut off VCSA
Unregister VCSA
Migrate its folder to the new datastore
Register it
Answering 'Moved it' when powering up at the net location.

When we power it up at the new location it reports Not able to open any disks...   In VM settings all disks appears as having zero bytes capacity,   However in the the target datastore all files (also .vmdk disk files) have the same size as their original (source folder) counterparts.

Any clues why we have problems migrating our VCSA?  

Thanks for comments on this.

I'm not sure what happened but I lost a data store and I can't get it back?  I have a Nimble storage unit with 3 servers attached all VM servers.  One of my hosts has lost connectivity to the Nimble.  Is there anything I can do remotely?

Our Windows Server 2012 R2 Hyper V server hosts a Windows Server 2012 R2 VM. An update brought an Integration Services Setup upgrade to version 6.3.9600.18692 (I haven't had time to locate which update this is). This upgrade doesn't appear to complete successfully in the VM, and a number of critical devices (including the NIC) have an exclamation sign on them. The Device status in the device properties says:
"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"

After much research, I was able to implement a temporary fix by pressing F8 on the VM's boot, and selecting "Disable Driver Signature Enforcement". The VM then boots into the OS fine, and the devices do not have an error.

But this is just a temp (and potentially unsafe) fix. This appears to have occurred previously when Integration Services Setup upgraded to version 6.3.9600.18398, with MS releasing a "fix".

I would like to resolve it permanently. Any help would be greatly appreciated.

Is it now possible within the latest version of VMware to view and interact with a virtual operating system that is running on the actual VMware server's monitor (without having to use the VMware vSphere client running on a seperate computer)?

My understanding is that Oracle DB licensing is based on number of cores etc. If you use virtual machines (e.g.ldoms) you need to partition it properly otherwise, in theory you have to pay based on the host machine.

 Can anyone confirm I'm right here? And explain it in bit more detail..


I can sort of understand how it works with physical server (find cores, use multiplier job done).

We've got a number of T3-1 servers.1 cpu, 2 core, 16 threads, ldoms see 128 VCPUs. If I have, say, three ldoms on this server, only one runnign oracle and this is properly partiioned to use only 16 VCPUs how does this translate to cores?

Need help to resolve the issue -As VM [2008-R2]is stuck with errors mentioned below -snap also attached
I can see multiple drive are showing there in vm, while in actual there are only 2 drives visible under os

and the server where this disk resides are functioning properly. If the file resides on removable media, reattach the media. Select button.retry to attempt the operation again.Select button.abort to end this session. Select button.cont to forward the error to the guest operating system.

Have a Test Domain - basic enough - 1 DC - AD/DNS/DHCP all done through Vm ware.

Added many VMs to this environment without any issues - all working as it should.

Then yesterday I built a vm and tried to add it to the domain and got message to say domain controller could not be contacted.

Can ping dc - hostname, can ping gateway from vm - will not add, get same message.

Then removed another vm from domain i built on monday - ask me to authenticate whilst removing to workgroup.

Ok I thought - we will reboot this vm and add it again.

But no - same message - domain controller could not be contacted.

Very strange and must annoying - everything points to dns but it is fine - everything is qualifying.

Any ideas?

I enabled in hyper-v 2012 the use of dynamic memory for a centos vm
centos-release-6-9.el6.12.3.x86_64
I followed these guidelines https://www.altaro.com/hyper-v/centos-linux-hyper-v/
I created a file in /etc/udev/rules.d/ named 100-balloon.rules
content:
SUBSYSTEM=="memory", ACTION=="add", ATTR{state}="online"

Open in new window


I setup startup mem 1024, minimal memory 1024 and max 4096

unlike other centos vm's I have it starts consuming all memory
so, i gave it 8Gb .. all memory was consumed
I increased the max memory to 20Gb, and it was consumed

I'll start out that I'm a novice and by no means a DBA.  Hopefully I explain this correctly and provide information.

We use a product called KANA and just upgraded to a newer release on a new VM.   SQL Server 2014

Without trying to say everything in one post (I can answer any questions if more info need) I'll start by stating my main issue.

The log file in the data folder is called Kana_Log.  Autogrowth is set to 10 percent and maxsize is unlimited.  

We do nightly transaction log backups and backup the database once a week.

I'm pretty sure we have have everything set up just like the older system.

What is happening is the kana_log file never reduces in size.  It just keeps getting larger and larger.  Recovery model is set to full.  I have reduced the size of the log file by using the following commands

ALTER DATABASE [mydatabase] SET RECOVERY SIMPLE
DBCC SHRINKFILE(<log_file_name_Log>)
ALTER DATABASE [mydatabase] SET RECOVERY FULL

The way things worked on the old server was I believe that after a full back up the log file would reduce in size.  It does not happen on the new server

I know I probably left a bunch of info out...please ask for more info in order to come to a solution

So bottom line is that the kana_log file just keeps growing and growing and never reduce in size unless I run the above commands.  

I may be wrong but isn't the log file supposed to reduce in size after a backup?

Thanks and look forward to any ideas on solving …

Dears.,

I have 2 Physical Servers - 1 Hosting 5 Vms and the other one hosting their Replica.
I am using the Windows Replication Services from Hyper-v

I would like to get a daily report by email that shows me if I have any problem with the replication.
I have found many PS scripts, but got lost, some are too basic, some are too complicated..
Is there anything "out-of-the-box" ? something Standard that any IT administrator should be looking at ?

Thanks
