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.

Windows 10 VM not booting after installing free Avast Antivirus. I suspect there is some driver issue. How can I remove the driver or uninstall Avast form the recovery console? Or is there another way around this?

Hi,

How can we migrate VMware servers from VCenter to MS Azure?

Which tools can be used?

Good day to All
I have some virtual machines with Windows 10 Pro installed on them, what is the best method for licensing them - I am getting conflicting information.  I want to use them as full PCs for one person each to RDP into, I cannot use VDI as I have bespoke software which is not compatible with VDI.
I am being pointed in the direction of CSP subscriptions which appear to be either user or device licenses - I feel that those are for VDI installations
The alternative offering is an upgrade to Windows 10 Enterprise but I don't need Enterprise so again I think that is for VDI installations.
So , in my case can I just buy Volume or Retail windows 10 Pro licenses and crack on.
Microsoft don't make these things easy, it should be sooo simple.
Thanks

I am building an Oracle Virtual Box VM on a laptop.  I have set the storage on the hard drive to 32 GB fixed.  I run through the install to the reboot.  When it comes back up it wants to reinstall CentOS 8 again and in the Installation Destination window the disc is still 32 GB but only about 1 MB is available.  What am I doing wrong? I follow the book and videos to a  tee but no beans.  And why do I need to reinstall CentOS?  I have set up VMs in VMWare just fine.  I am new to Virtual Box.  Can you help?  thanks.

I currently have a server running server 2016 with two guest VM's also running - a 2016 DC and a Member server running exchange 2016.

I now have a new server running Server 2019 and wanted to move my Exchange server to the new host.

I did the following:

1. Powered off Exchange
2. Copied both the System VHD and the Database VHD to the new host
3. Created a new Virtual machine using the same MAC address it had previously and made the both drives had the same letter.
4. Booted the VM up and it did say it was configuring new hardware.

When I logged in it all seemed ok, albeit a tad slow but the Ethernet card was not present. There was an unidentified item in Device manager which are 3 attempts it did installed the network card but failed to show in network connections.

My questions are - should you be able to just move a VM from 2016 to 2019? Did I miss any steps? I was quite careful in the process to move over a VM.

Any thoughts or tips that might help will be much appreciated

Thank you.

I have a cloud subscription in Azure. I can create a standard VM without trouble in the portal site, but I need to create it as a dev/test VM. There is not an option to select the VM as a dev/test VM in the portal.  I was able to create an estimate which gave me all the SKU's and Resource ID's to create what I want.  How would I go about creating that exact VM?

I have a legacy Win98 box that I need to virtualize.  I've got it successfully P2V'd into VMware Workstation.  The problem is that it's a single hard drive with a 2gb FAT16 partition and a 14GB FAT32 partition.  I've been able to successfully convert the FAT16 to FAT32, however, I'm pulling my hair out trying to resize the partitions.  I need to resize the 2gb partition to 4gb.

I tried using a partition tool in a Win7 VM to resize.  When I boot the Win98 box I just get a blinking cursor.  How do I successfully resize these partitions?  Or, I think I successfully resize the partitions, but messed up my ability to boot.  I tried booting the 98 install CD and getting to a command prompt.   I ran FDISK /mbr.  It didn't do anything....

Windows Server Standard versus Windows Data Center edition.

I was reading the differences:
<https://docs.microsoft.com/en-us/windows-server/get-started-19/editions-comparison-19>

Can be used as virtualization guest      Yes; 2 virtual machines, plus one Hyper-V host per license      Yes; unlimited virtual machines, plus one Hyper-V host per license

Why would someone order the datacenter edition when setting up a machine with windows?

I'm thinking perhaps they want to become a service provider, and host servers? Maybe game servers?

How would this function with ONE database? Would that have anything to do with load balancing a database? I don't think so. But thought I would ask.

I have Veeam Back Up and Replicate and the (VMware) VM's back up jobs are pointed to a local Nas.

On the Nas i can see a drive called Veeam and in there are folders that have the VM files.

In each of the folders are files, one called (Backup Name).vbm and around 12 large files with file extension .vib.

Can i copy these on to an external drive and keep the files offsite?

In the event of a disaster is it just a case of putting them back to the same folder and setting up Veeam again.

I've just loaded ESXI 6.7 and configured a server.  I can't login becuase it's not responding to my keyboard or mouse.  I can't install the tools because I can't get into the server. It's server 2019

A friend runs an exchange 2016 server in his home garage for his small business.  It runs as a VM on a hyper-V host with another VM that is the DC.
He recently moved and in the process changed the IP address on the servers. Since that time, inbound mail appears to be accepted by the front-end receive connector, but does not make it to the recipient mailbox.  
Running get-transportserver | get-messagetrackinglog -recipient="useremail" shows me a fail on the routing step.
Running test-mailflow -targetemailaddress <addresshere> waits a very long time and finally returns a failure
How do you get from knowing it failed, to knowing where it failed???

When I add a new blade to a UCS chassis the server profile from a template has it create six vNICs - two for mgt, two for iSCSI, two for data. They are numbered 0 through 5. And so it is also on the VMWare side where VMNICs are numbered 0 to 5. But the last time I turned the newly registered server over to the VMWare admins the VMNICs 0 through 5 had the mac addresses all jumbled up. What was 1 in UCS might be 4 in VMWare, 2 might align with  3 and so on. My question is - what mechanism determines which NIC as defined by its mac address is associated with what sequence number in VMWare. Is it just a matter of how the VMW engineer selects the NICs for attachment to the VM? Do they all come in at once and VMW just decides the sequence number of each? Inquiring minds want to know!

TY

Error installing virtual machine with Server 2019

I am in the process of setting up a Lenovo ST550 server.  I am using the Lenovo ROK version of Server 2019.
The installation up to getting HyperV functioning has gone well.

When I create a virtual machine, I get to the install operating system and all goes well until it gets to the features install portion,  I get the following error:
"windows cannot copy files from D:\sources to C:$Windows.~LS\Sources.  Make sure all files required for installation are available, and restart the installation.  error code 0x80070001"

I have tried with the Windows trial version of Server 2019, and it works fine.  My problem using it was that it would not accept the licence key that came with the Server 2019 from Lenovo.

The ISO file that I am using [from Lenovo] is installed on a USB drive that is formatted NTFS.  The boot .wim is 531,550 kb. while the one from the trial version is 534,731 kb

At my work place - I regularly see messages like this in Solar Winds warning of latency between ESXi hosts and their data store. I have no idea why 20ms is chosen as the warning level. And I'm not sure exactly what type of latency is being referred to in this context. With ICMP I'm familiar with RTT time. But I imaging this is a different measurement. Does anyone know how vSphere measures "latency" from an ESX to its datastore? From a VM to its datastore? Thank you.

"NetPerfMon Event Log : The total latency between a san-server-01.acmeloans.com and a datastore is above 20 ms." action was executed successfully

In your environments do you have any VM's that you do not backup as a matter of course? Our admins have sent through 'what we currently backup' in Veeam but a quick cross match to a list of all servers in the domain show some servers are not being backed up at all (which may be purposeful - hopefully!). I was just interested if this is common and examples of VM's where you don't need to backup the configuration/data?

Also in your experience - how easy would it be for an admin to miss something critical in terms of VM/virtual HD in backup selections? Realistic or very rare?

What kinds of security features are typically available with modern NAS storage devices, e.g. what are some of the more common controls to make your NAS device and the data held on it as secure as possible. Obviously is a different beast to say a VM Windows Server but there must be some consistency in terms of logical security controls to put in place regardless of make/model.

I am doing some research on the CIS top 20 controls and trying to decipher what exactly this is suggesting:
"Ensure that all backups have at least one backup destination that is not continuously addressable through operating system calls."

1) In terms of say Veeam backups what is it recommending in terms of backup destinations? What would constitute "not continuously addressable through operating system calls", i.e. if you write your backups to a NAS storage device, and those are replicated to another storage device 20 miles away, how can you determine whether that meets the criteria of something that is "not continuously addressable through operating system calls"?

2) From a basic management level perspective, what exactly is "Ensuring that all backups have at least one backup destination that is not continuously addressable through operating system calls" protecting you from/why is it so necessary?

1) With Veeam is it common for an organisation to create a backup per VM, or could you technically bundle VM's into the same job? I am just interested in the logic behind one backup job per VM and if this is typically a usual strategy and if so why would that be?

2) Is there granular access controls to the veeam backup and replication console, and if so where specifically can you get a list of users/roles? Are these defined with the veeam console itself or integrated with the server on which the console is installed upon? E.g. windows/AD accounts?

3) Is the configuration database behind veeam backup & replication typically Microsoft's SQL Server or by default another platform?
0
1) Does a veeam backup job typically constitute a 'Complete System Backups' – or is it highly configurable what the job will or will not include? E.g. could you restore the entire server (OS, App, configuration, data in a single restore operation), or does that require multiple steps?

2) Is there some form of screenshot on the veeam job properties which shows what specifically the job is backing up? I am a bit blind to the management side of Veeam Backup & Replication but need some supporting evidence from the admins for an audit.

3) Do you still do test restores of veeam backups, and what kinds of issues have you found that meant the veeam backups did not restore, or are they pretty 'faultless'? Not sure if the testing is quite an aged concept or still valid?

are there any specific veeam security best practices in which to review our compliance against? Obviously access to backups of sensitive systems is as dangerous as access to the live copies of the data so we need to verify we have done as much as physically possible in veeam and the storage as possible to keep the backups secure.

Out of interest if you got access to the backup files but did not have a copy of the veeam backup/restore application, would they be of much use to an attacker?
