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 currently have a 2008 cluster environment with VM's on the cluster.  Want to create a two node cluster environment with 2016.  

2 part question:
A. can 2008 R2 cluster and 2016 cluster co-exist so we can migrate the vm's one at a time. (to eliminate downtime).
B. i know there's a path of upgrade from 2008 R2 cluster to 2012 cluster, then to 2016  back in May of last year.  Is there a path now that's direct from 2008 R2 to 2016?

On a Server 2016 base server do the Hyper-V guest integration tools still need to be installed on guest Server 2016 operating systems?

if your SAN replicates to a DR SAN at hardware level, e.g. everything, does this reduce the need to have backup software that also has a software level replication element (i.e. veeam), e.g is this duplicating the same feature of the SAN's built in replication facility, or does it offer benefits above and beyond?

I have a test domain setup - all is fine with this setup.
By design the devices do not get an outside gateway.
So - 2 DC's - multiple servers/workstations all VM's on a VM Adapter with 192.168.x.x

However on some of the devices there is another adapter pointing to another domain.
This adapter gives ultimately access to the outside world.

Up until 3 weeks ago - everything was grand, no issues at all - DNS was absolutely fine.

However now - when both adapters are enabled - nothing is working at all - devices cannot see their own domain and Users cannot login.

When pinging the main DC - it comes back with a strange resolve name - xxxx.no-ip.org (random IP address).
And when I disable the 2nd adapter, it then resolves fine.

If I do an IP config - it resolves with correct addresses.

Have checked DNS on both domains and seem fine - but I am obviously missing something?

I have the last two VM's to migrate to a new Host.

1. Is there anything I need to consider with moving the vCenter vm to a new host (Usin Veeam quick migration)

2. I plan to use Veeam copy to copy the Veeam server to the new host - then power-off the original, then power on the copy on the new host - is this plan OK?

I'm trying to make a backup with VMware VDP 6 to two VMs one with Exchange server and another with File server, but I'm getting this error: An error occurred while quiescing the the virtual machine.
The two servers have windows server 2016.

Thank you in advance.

Hello Experts - I am doing a fresh install of XenApp Server 6.5 on Server 2008R2.  When I click Add Server Roles I get the following error:

XenApp Server Role Manager\Startup\StartupIndicator.exe exited with error code -1.

Googling this came up with a few work-around, none of which worked for me.  Any ideas on what I can try?

Hello everyone,

We are overhauling our infrastructure and wanted to know some opinions on both of these SAN units. We are looking into the Netapp FAS2650 & Tegile T4100 IFA to house our VMs. Biggest concerns are how well both integrate and function with Veeam 9.5 and ESXi 6.5. Does anyone have major issues or gripes with either one of these? We are planning on using iSCSI for the protocol, but heard NFS is gaining popularity. Which is a better practice, still continue to use iSCSI or use NFS? Any benefits or cons of using one over the other? Here is a quick rundown of our proposed infrastructure:

2- ESXi 6.5 hosts (Cisco UCS C220 M5s)
~200 users
~25 Virtual Machines
Planning on using 2x Nexus 3524x for the server backbone (all 10Gig including SAN & hosts)

Would appreciate some opinions and recommendations.

TIA!

Hi,

I have a clean Server 2016 STD with Desktop Experience (GUI) VM running on Hyper-V (2016).

I want to generalize the VM in order to use it for cloning / distribution (so that I don't have to install the next VM's from scratch).

On Server 2012 one could run sysprep / generalize if I am not mistaken, what is the way to do this on a Server 2016 OS? I guess that it is now done in Powershell, I do recall that it was quite straight forward when I recently studied and wrote my MCSE, but for the life of me I cannot remember how to do it now that I have to physically do it...

Thanks for any assistance.

Reinhard.

1) If for your DR/backup you initially write backups to your primary SAN, and then there is a hardware level replication between your primary SAN and DR SAN, therefore the same backup files are on 2 SAN's in differing offices, would this classify as 2 copies of backups. I know for critical systems best practice states have 3 copies, would this class as 2?

2) also - what kinds of issue/risk/incident could take out both your primary SAN and DR SAN, therefore leaving you without live copies of data and backups? our technical team say their DR setup is sufficient, but from our risk angle we want to have some view of risks and probability to see if a 3rd backup is required?

3) And also - given the setup I have described, what options could there be for implementing a 3rd copy of the backup, e.g. tape backup attached to the DR SAN and taken offsite?? The budget is limited so need to determine if a 3rd backup is necessary and what options could be used, and some idea for each option which are the less expensive and which are the more expensive?

4) Is 'primary SAN' the correct terminology to describe your SAN in your main data centre? And is 'DR SAN' the correct terminology to describe the SAN at your DR site?

I'm looking to configure a VM lab where I can install separate OS's for development testing and learning but I'm not sure what is the best setup for this. I'm running Windows 10 and have a 1TB external hard drive i'm planning to use as storage for the VMs. I just need a low-key personal lab but need some direction to get this set up.

Thanks!

Small environment. 4 hosts. Just got two new ones.
esxi 5.5 the Windows vCenter has had so many issues before my time. All sorts of SQL issues, multiple DB and Full restores from Veeam. old 2008 non R2 server with app crashes and certificate errors out the wazoo. Migration assistant to vcsa is failing, logs full of errors.
That said, the hosts and vcenter do run, and VM's are stable, on the surface.
There is a distributed network switch, so I'm wondering if it's best to just spin up a brand new VCSA. Export distributed network switch from windows vCenter, then import into new vcsa. Then connect the hosts to the new vcenter?
I don't care about retaining any historical data.

My VMs that usually works until last week., but MS update this week managed to break them with the attached error.
This error is the same for all VMs. I am using Oracle Virtual Box  5.1.14

Is there a way to make the VMS run again? if needed to upgrade do I need to run guest additions again?

Dear Sirs,
I am very new with Network .I have several problems above my Network Plan:
 my network
1.i do not know which Network cable to which port.
2.Vlan create problem,i think i need TRUNK too,but several attemt no succes:(
3.vswitch how to
4.ISCSI connection to ESXI , This my big problem at the moment . Do i need to use different IP  subnet for ISCSI ? do i need to connect VLAN ISCSI the same portgroup where is all my VMs(VM Network) or do i need to create VM Network 2 ? if yes how connect my VMs on VM Network 2 to VM Network ?
why i ask that ? because i did a test .
1. Created a Domain Controller vm on VM NETWORK.
2.I created a windows 10 client on VM NETWORK 2 .unfortunatlly window 10 client cant ping to Domain controller.

for now all my problems.
Thank you so much for your help and ideas
My Best Regards

I am trying to understand What Synthetic Full Backup backs up as data.
I thought it will create a full backup from storage and inject the incremental backup it has created the same day to the Full backup.

However looking at the Veeamone reporter, I see under Transferred (GB) column 48.13 GB,  it is less than the incremental one day before.

Any Veeam Expert to explain the report as shown in the screenshot below:

Thank you

Hi, I am trying to determine if I have Hyper-V manager server role configured correctly for my virtual environment.  In particular, virtual switch manager.  Why is it using an actual IP address from my network?  And is this necessary?  If not, how can I go about allowing it to reach my DHCP server on the network for the VM's that reside on the Hyper-V host server, yet not use an IP address from my very limited available IP's on my server network?

Hyper-V Host Servers:  Microsoft Windows Server 2012 R2 - Standard & DataCenter editions


Let me know if you require further details/information to answer these questions.


Thanks in advance.

I am having problems with a new Windows Server 2016 VM.  This server is a print/internal web server.  I have webroot installed on this computer and I also noticed Windows Defender is also active as well.  I have noticed several things that are odd.  For instance, I have an hosted app on this machine that will launch but immediately closes after entering the username and password.  However, on the same machine I installed Firefox and it works fine.  The software provider for this app indicates a 405 error is occurring with IE.  I have the app defined as a trusted site too.  So for now I am using Firefox to logon to the app for now.

We also use Quorum OnQ to backup our hosts.  Since this server has 1.5 million files it took a little while for the initial backup which is normal.  However, performing following backups takes 5 to 6 hours because it has to scan each file to see if changes were made to back them up or not.  So, I enabled QFiltering for this server since this feature will build a database of all the files so that it does not need to scan all files.  Once I enabled QFilter, Windows will not allow the QFilter service to start (Event ID 7000, Service Control Manager with error:  Windows cannot verify the digital signature of this file...  Also, the Qfilter service uses SquirtCopy.

So in order to get a backup of this critical server, I disabled Qfilter and the backup ran last night.  It took about 6 hours to complete.  Early this morning around 5:40am I remotely …

Hi Everyone,
I had a client who is using Windows 7 and Windows XP Mode have their Windows XP VM stop working. I am thinking the key to solving it is the Integrated Features options which is grayed out. Does anyone know how I can make these options live so I can uncheck the selected devices?

Hi,
I'm facing an issue with my Hyper-v host 1 . last couple of days when the backup job run to backup hyper-v host including virtual machines . I get below error and virtual machines lose network connectivity and loses the failover cluster communication .

"Failed to allocate VMQ for NIC B038F6F3-B1DB-48CF-9566-A98A0E7340F0--D5DAA699-7131-42C1-B895-3658D6F16959 (Friendly Name: Network Adapter) on switch 91306166-6B98-498C-B029-D552838FCD61 (Friendly Name: External). Reason - Maximum number of VMQs supported on the Protocol NIC is exceeded. Status = Insufficient system resources exist to complete the API. "

usually the virtual machines can be reached on network in 15 minutes . but its been 8 hours a mailbox server virtual machine is not accessible through network and i have tried accessing through hyper-v manager but its unresponsive .even i tried shutting down from hyper-v manager but throws me error. Is there any way to access the unresponsive mailbox virtual machine other than turning it off from hyper-v manager at the moment make the mailbox server up.
I'm desperately waiting for a help .
Thanks in advance.

Hi, I did windows updates and they crashed my Exchange Server VM (Server 2012 R2+Exchange 2016).

When I got Windows back up, and the Exchange Services running again, I noticed I could not log in, I lost the Trust Relationship between the Email and DC.

I got that fixed , and email back up, but then I noticed everyone in the domain lost all their email back to last Aug.  New emails were coming in and being delivered, and we could send emails out.

Logged into ECP and noticed the Database was in Failed mode, so I got the Database back to Healthy, but I'm still missing my emails.

I do have backups, but was wondering if there was anything else I can try?

Thanks!
