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.

We have sold a portion of a business and we need to provide the buying company with a copy of a VM and still have the VM running in our environment.  

Can I simply shutdown the VM, do an Export OVF Template and then start the VM and send the other company the OVF file?  

The real question is: if I do an 'Export OVF Template' does the original VM still exist and will I be able to start it and run as before?

Thanks,
Rob.

I converted a physical machine to a Hyper-V VM using:  https://www.experts-exchange.com/questions/29103396/Convert-physical-Server-SBS-2011-to-a-smaller-partition-into-Hyper-V.html#a42625473

Now when testing the VM I am having connectivity issues.  For starters I can ping the machine by ip address from some other servers on the network but from others it doesn't ping.  Also, from any device that I have tried I am unable to access the shares on the server.

Not sure how to go about diagnosing what is going on or why it is different now that it is running in as a VM.

We are having some problems using the Android Studio emulator in a virtual machine. When connecting to the virtual machine with Windows RDP protocol, we are able to launch the Android emulator without issue; when connecting with PCoIP or Blast protocol or to the virtual machine console, we get a strange error code from the emulator. We would like to get this functioning with the Blast protocol rather than having to use RDP.

Hi All,

I am facing an issue while configuring soft zoning for host and 3 par.
when I activate zoneset on Switch1 , Switch2 zones deactivates and show 0 active path on storage and vice versa
only for 3 par. Other zones for other storage are still intact on those switch.

Hi

Ive got a HP MSA 1050 which has two controllers on the rear which has fibre connections (see image). I want to connect this to my network switch which is a CISCO 3560G Network Switch. What exactly do I need to connect it to the network switch so I can then attach it to my VM Host via the network?

Thanks

I have searched the internet and don’t k now if there is a solution to a problem we are facing.

We have received Windows 2008 Sever backup images from a customer.  
These images are rather large. Some are 540 GB and some over 1 TB.  

We need to covert the images to VMware ESXi 6.0 VMs.  

However, we are currently restricted by datastore space.  
The most we have available is possibly 500 GB.

We cannot connect another drive at this point or add an external USB drive.  

We are guessing that backups don’t reflect what the actual total size may be.
Possible only 20 GB of space is actually used.

Is there a way to shrink a Windows Backup Image?

I know in VMware converter, you can shrink a volume, but we cannot build a VM and attach a converted image (vmdk via Starwind Converter) as the space is limited.

thanks

About two weeks ago three of our Veeam back up jobs began failing (they've run for a few years prior to this). We get a (503 Server Not Available) error. I am able to RDP to the computer. It has a working internet connection. When i go to the web browser address, though, i get the same 503 error (i'll attach screen grab). I've rebooted the computer and the host. That did not help. Nothing has changed in our DNS/Networking and we've been using the same firewirewall for years but these servers are located on the same network.

Vmware ESXi is version 6.0.0 for the host.

Not sure what other information i should provide.

Any suggestions would be great. Thank you.

2 Node, Server2016 Hyper V Cluster connecting to a SAN via iscsi.
The San has a total of 3 LUNS.  2 For the vm's to "live" and one for Quorum.

When I pause Node1 and drain the roles.  The VM's drain to Node2.

When I pause Node2 and drain the roles, both  Cluster Disks go offline and the VM's autopause.

During the outage, I was able to ping the iSCSI ports on the SAN and I disabled AV/Firewall on the hosts but that did not resolve anything.
Only resuming Node2 brought the CSV's online.

This cluster was able to failover properly in the past and my lab is failing over correctly as well.

I don't want to run the ClusterVal Wizard until my next maintenance window ( JUST IN CASE ). Before I do run the CLusterVal, has anyone ran into this scenario before?

Hi,

I have a Windows 2016 Server Standard with Hyper-V installed.  I have two VMs:  ADSRV and RDS (Active Directory Server and Remote Desktop Server).  Something happened the other night and now the RDS is in a Saved state.  I've seen this before and I was able to delete the saved state and continue on as usual on another server.  This time, if I try to delete the saved state, I get an error message:  An error occurred while attempting to delete the save state for the selected virtual machine.  RDS failed to turn off.  I've checked the details on the tskmgr and the only vwmp.exe that's running or showing up is the ADSRV.  Microsoft's website said something about deleting .bin and some other file.  I couldn't find those files in the VM folder.  I found the vmcx and vmrs files.  How can get this VM back up out of the saved state?  Any help is greatly appreciated!

Hello,

I am looking fr advice on a backup strategy. Currently my environment has the following specifications:

2 x  VMWare ESXI Hypervisors connected to a SAN with 12 Virtual machines
9 TB of storage space
Physical server (end of life) that has an LTO 5 tape backup unit capable of 10+ TB of storage; It is connected to a cheap 54 TB NAS which holds all backup data
Licensed with Veeam Enterprise 9.5 (to backup VM's)
Licensed with Symantec Backup Exec (archive data to tape)

The above description for backups (and more or less disaster recovery) is in my opinion an outdated method of doing backups. I would like to move to a more modern method that meets the company goals.

I would like to do the following:

Have a retention period: 30 Days, with ongoing monthly backups
-preferably ability file level restore
-Backup to cloud or offsite data center
-Ability to restore images in Amazon (or another ESXi server) in the event of a disaster at HQ
-RPO of 24 hours
-RTO of 4 hours (if possible)

Data is safe and destination of backups needs to be a proven reliable source. Backed up data is encrypted.

I am on a tight budget.

One of the recommendations on this site was to use CloudBerry with Backblaze. I am not certain if this a good commercial solution for Disaster Recovery and backups

I still have the ability to backup everything to disk and then archive to a cloud storage vendor, although I imagine restoring data would be quite slow, even with a Gigabit …

Hello all,

I cannot make a Hyper-V backup because the backup software does not see Hyper-V / VM's. That is because when I do a : "vssadmin list writers" the Hyper-V writer is missing.

Anyone know how to resolve that?

I have a Hyper V server  with 3 guests.
The host only has one partition so hyper v is running on the local C: drive.

I'm going to do a one time backup just for disaster recovery purposes. In case the whole server goes.
Would it be beneficial to do a one time backup of the whole host using windows backup?
And then I could restore the virtual machines using image restore to the VM.


This customer uses Datto Backup for the guest servers.

Hi All
I am in the process of deploying exchange 2013. I have used your videos to learn about exchange 2013.

I have a vm environment in which i have 2 2012 DC's and 2 exchange servers. one is 2010 and the other is 2013.

My challenge is that i am unable to connect via outlook on exchange server 2013 itself. It first said there is no default gateway so i followed experts exchange suggestion to change registry which didnt help.

When i try to configure outlook Auto account setup is able to find my username with email address. After this i click next and i get a security certficate error indicating the name on the security certificate is invalid or does not match the name of the site. i click yes to proceed. After this it gives me the following

"The action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action"

If i click ok, i get a sid like number @mydomain.com. clicking ok results in logon to server with a cross sign. thus i am unable to proceed any further

Requesting assistance on this please. Thanks in advance for your assistance.



The suggestion from expert exchange was as follows
Click Start, click Run, type regedit in the Open box, and then click OK.
Locate and then click the following subkey:
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\RPC
On the Edit menu, point to New, and then click DWORD Value.
Type DefConnectOpts, and then press ENTER.

I need to create a volume with "Bytes per Physical Sector" = 512 so I can use it as the staging location for Backup Exec (using GRT -Granular Recovery Technology) to restore Exchange (physical 2007) mailbox / items. (I know this setup is old. We are migrating.)
GRT requires the staging location have the same sector size as the volume from which the Exchange log files were backed up.
 
To do that, I added a new VHDX to the Backup Exec server (a 2012R2 VM on 2012 R2 Hyper-V host) and then I issued  
"Set-vhd VHDname.vhdx -PhysicalSectorSizeBytes 512"
to change its Physical Sector Size to 512 bytes. I did verify using "Get-vhd VHDname.vhdx" that it shows PhysicalSectroSize = 512.
But to my surprise when I got in to the VM and issued the following command on an elevated command prompt:
fsutil fsinfo ntfsinfo D:  (where D: is the VHDX I just created)
it shows the "Bytes Per Physical Sector" = 4096

I'm confused... Why are they different? Did I miss anything? How to create a vhdx with "Bytes Per Physical Sector" = 512

I am still somewhat new to Virtualization and I am currently in the process of upgrading/expanding my VM server farm. I was going through some documents and in of the documents it mentions that I should have a separate disk array for each virtual machine on a multiple virtual machine system.

My question is what do they mean? I have a 6 disk server and would like it to host 3 VM's. From how I read the statement above I should configure server into 3 RAID 1 configurations where normally I would configure either a RAID 5 or 10 then split the array into however many disks I need for the 3 VM's.

What is the correct way? Right now I have all of my VM servers configured as RAID 5 the chop up the array into drives for the VM machines

Hi

I am looking for advice on the following:

I have an issue within my Citrix VDI environment, that when VDI Desktops not in use are powered off for a pre-longed period of time, they automatically get placed into Maintenance mode. According to a Citrix article there is a DWORD to amend to be able do disable this behviour, which involves changing to a NEGATIVE value. I can't see how this is done as my undserstanding was a DWORD can only accept a 0 upwards:

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

DesktopServer\MaxFailedRegistrationsAllowed

DWORD

2

Controls automatic placement of power-managed VMs into maintenance mode following repeated failures to register with a DDC.

If a VM is started-up by the broker service but fails to register after the period defined by the MaxRegistrationDelayMin setting (default 20 minutes), it is shutdown again.

The MaxFailedRegistrationsAllowed value defines the maximum number of times that this start-up, registration failure, shut down cycle is allowed to repeat before a subsequent registration failure causes the VM to be automatically placed into maintenance mode.

 

The default value of 2 means that if the VM fails to register 3 times in succession, it will be automatically placed into maintenance mode.

Setting MaxFailedRegistrationsAllowed to a negative value (0xFFFFFFFF) disables this behavior and prevents VMs from ever being automatically placed into maintenance mode.

When I restart the Server 2016 Hyper-V base server (which has 5 Server 2016 virtual servers running) the virtual servers all have the "Shut Down event tracker" notification window that displays once the base server boots back up and I connect to these virtual servers.

Does this mean that the virtual servers aren't being shut down or restarting properly?

Hi,

We have a Windows 2012 R2 domain controller Hyper V running on a Windows 2012 R2 server. We are getting speeds of 45mbps up & down but they Hyper V is barely reaching 8mbps.

The Hyper V has 2 processors & 16GB RAM so really more than enough for it. I have turned off VMQ's on the Hyper V (as per a quick google search) & this increased the speed a little but not very much.

Any ideas on what I am missing?

I have recently installed an Ubuntu 16.04 VHD image. Initially the /etc/network/interface file was empty. I put in the ip address info that I was provided by our network guy.
ifconfig showed eth0 as the interface name.
I edited the interface file to have the following:
auto eth0
iface eth0 inet static
address 10.100.1.6
gateway 10.100.0.1
submask 255.255.248.0
dns-nameservers .....

the network folks changed their minds and wanted to put my server on a different subnet.
I have edited the interface file.
auto eth0
iface eth0 inet static
address 10.99.0.6
gateway 10.99.0.1
submask 255.255.240.0
I have flushed the interface.
I have tried rebooting and actually shutting down the system.

but each time when I boot back up the interface continues to be configured with the old IP.

what am I doing wrong?
What do I need to do in order for the new IP to be loaded into the configuration?

Thanks in advance.
