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.

Are there any standard risks (by this I mean those that could affect any VM regardless of its purpose) that can be used for risk assesment purposes for virtual servers above and beyond security related risks/common issues. We need to assess all common technical risks be those performance availability security for all virtual servers which process critical services. And some insight into common causes which make the aforementioned issues happen and occur.

I deleted a volume on my storage without unmounting it in vSphere.  Now it no longer shows on my storage, but it does show in vSphere.  How can I remove it from my vSphere environment because I cannot delete or unmount the volume in vSphere (it gives an error if I try because the volume doesn't exist any longer).

Hi again all,

I am new to the virtualization world, and am learning new things everyday.  Today i came across cloning and how to clone virtual Machine and how to create a template and all.

My simple question (out of curiosity)  is for the people with real life experience, what commands do you usually run in a new cloned machine under the run once configuration option ? And suppose am using a windows, when and where are the commands being run?

Thanks in advance!

we need to do high level risk assessment of a VDI (vmware horizon view). E.g. identify potential risks and then look how the design/management/monitoring mitigates against those. The main risks we could think of were the obvious - availability & acceptable performance etc, but am keen to know what kind of risks you would suggest are assessed with such a technology, and the common mitigating controls you would seek assurances on.

Hi all,

Am running a lab setup on a server that has 32GiB of ram and 2x intel xeon @ 2.44Ghz, plus my laptop that am basically using the navigate through the ESXI.
Am currently running the 60days free trailer version on my server of the ESXI 6.5, and i have made 2 VM's on my ESXI host, the first one being a windows server 2016 with the active directory enabled and configured and the second VM is a windows server that is connected to the domain but with Vcenter running.

note:-
Each of the servers is running on 16Gig of ram and 8VCpu's.

The main problem am currently facing is that i can't open the Vcenter from my web browser (on my laptop), the only way to open is from the Windwos server that am using for the Vcenter (local host) and i had to install google chrome and adobe flash player to be able to open it from the server, another thing i would like to mention is, Yes there is communication between the server and the my machinethe connection is done. before i choose, but after choosing how to access the Vsphere , the connection is lost or dropped, am not sure why.after i choose vSphere Web Client (Flash)Please help me!

I am interested in running a 2016 windows domain controller on a physical server and then having an exchange server 2016 on a virtual machine on the same physical server, are there any issues with this?

Hello, I am search for a VDI solution so we can "host internally".  I want to avoid replacing all the desktop hardware and I want to support a remote office.  The main application will NOT run over a WAN.

Is HyperV the best solution?

The main application will run on windows server 2016, with MS SQL and integrates to MS Office.

What would be a good terminology be for your host servers and storage area network? 'Infrastructure' seems quite vague and presumably could include other network equiptment. We want assurances on the documentation of this key area of the network but was after a term that could be used to describe the hosts and storage - any inspiration most welcome.

We are trying to find out how to redirect Onedrive/Box/Dropbox to a shared network folder. We've done some research and if it's possible it seems to be done with a lot of "hacks" to make it work.

Has anyone done this successfully?

Any help will be appreciated.

Guest VM cannot connect to my Host machine's Wifi adapter. Using VM Workstation version 14. Using bridged networking, but in the VM, it shows the NIC as a physical NIC rather than Wifi. My host machine is using a Wifi NIC . The VM NIC shows it as no connection. How do I pass network connectivity to the guest VM if my host machine is usning a Wifi adapter?  Both machines are Windows 10 Home edition.

What is the recommended topology for a two site configuration for VMware vCenter and Site Recovery Manager?  Would there be any issues with all services (PSC, vCenter, & SRM) all residing on a single VM at each site?  Should each service be installed a separate VM (3 servers per site) or can I combine at least two of these services into a single VM (2 servers per site)?  If I am able to bundle two services into a single VM, which services can we safely bundle together?

Our environment is not too large, about 25-30 VM's in total.  I am trying to determine if I would be able to reduce disk space by bundling services into fewer VM's, but am unsure if that would cause any issues.

Thank you in advance!

My VHD keeps expanding and the physical space is going to be full. I do not know what to do.

DIsk: Logical F: 300GB
HyperV disk: Dynamically expanding virtual hard disk
size: 250GB
Maximum size 250GB.

Now the vhd is 280GB.  I only have 14GB left. When i shutdown the VM, the host disk (F:) will have about 40GB left. After one hour later it will go back to 14GB because the VHD expands back to 280GB. Tomorrow it will expand further.

I really don't know what to do. please help. Urgent. It is an Exchange server.

Hi,

I have a Synology NAS 918+ with 3TB WD Green drives. I have them running for some years.
2 disks are showing errors once and a while. I'm not sure if I should replace them all (quite costly, just bought the DS918+).

What disks would you advise to use (home usage, running virtual machine manager but could buy the SSD cache to optimize speed).
3TB is good enough, 4 TB is also an option. Budget is around 300 Euro.

Trying to set up a Win 7 VM on my win 10 pro laptop, but am unable to get internet access.
Going to my WiFi adapter properties & checking the box that says 'Hyper V Extensible Virtual Switch', I get a pop up that says 'Your current selection will also disable the following features: Hyper V Extensible virtual switch.
So, enabling it, is actually doing to disable it?!?
Laptop only has wireless adapter. Will/can this work easily, or should I just go get a USB LAN adapter, or will the USB pass through issue kill that idea?
Either way, when I go back to propewrties, the box is unchecked again.

Good Morning,

The increment of a datastore, can be done, so they have record of the vm.?

Or do I have to carry out a storage vmotion and leave that datastore empty in order to make the capacity increase?

We are needing to reduce the hard disk of a VM guest from 400G down to 100G.  The only way this is possible, we understand, is to use the Standalone Converter.  We are not sure whether the source VM needs to be on or off for the procedure, and how to specify the "source", as far as what category to select.  Any help is appreciated.

Thanks

Currently have a very small environment on a physical box - 3 VM's, small domain - done through VM Workstation.
Now I have moved the 3 VM's to an existing host. Esxi 6.5.
Then register the VM's - does so successfully.

However - when i try to power on the VM's, I get the following message.

I have schedule a Veeam backup and keep the file for 7 days.

I have run a full backup once only and schedule the task to run differential copy every day.

After 7 days, will Veeam will merge all the differential copy into the previous full backup automatically. Do I need to manually run full backup again at the end of every 7 days ?

Thx

I have this unusual problem in a Virtual Box Server...  For some reason the 2nd networking device does not connect on boot up and there is an error when I issue the command:
sudo /etc/init.d/networking restart

However if I use:   sudo ifconfig enp0s8 down  followed by sudo ifconfig enp0s8 up  
then I am magically connected.

I know I'm good because I can or can't ping the gateway 192.168.14.3  (and the host computer can ping back the Virtual Machine)

I would also appreciate any info on how you went about diagnosing the problem.

-------------------------------
Here is my interfaces file
# This file describes the network interfaces available on your system
