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 am using virt-manager to create VMs on each Linux host. In order to access the VMs, I have to open up virt-viewer on each host. Is there a tool that I can use to consolidate all of the VMs into the same GUI console so I can view and use them easier?

When trying to migrate a VM running windows 10 i get :Virtual machine is configured to use a device that prevents the operation: Device 'HD audio ' has a backing type that is not supported. "This is a general limitation of the virtual machine's compatibility with the ESXi version of the selected host."

It was P2V but have no need for audio but see no way to remove or disable in device settings for the VM, does it have the be removed from the OS?

I have a  vSphere Client 5.5 with a Windows Server 2012 R2 and as a guest VM. The funny thing is that the num lock key set to ON when I move the cursor into the VM. When I move it out it willl set my num to OFF.

Greetings!

We have a virtual machine that sits in on an ESXi 5.5 development server, runs Scientific Linux 7 and is provisioned for 800 GB of space.  We want to move it to a production server, but since it is only using less than 50 GB of space, we would love to provision it to use 100 GB.  How should we proceed to move/compress this VM at the same time?  Use the converter?  Any guidance/instructions will be most welcome.

Hey all,

I am thinking of creating a virtual machine for one of my clients using Hyper-V. It will be a terminal server environment where they will be using a cetralised database and accessing emails and docs. Their documents folder is only around 50GB and they have been getting away with 240GB up until now but I will increase a little when I build it. My question: Is there a need to partition the OS from the data drive.. will this provide any increase in performance or reliability?

FYI We will be running SSD drives with 32GB RAM, 8 vCPU cores which I think is ample.

CPU and VMsHi,
 I have a new server running Hyper-V 2019 and it came with two Intel Silver 4110  @2.1Ghz (8 core) CPUs and 64GB of RAM.
 I have 4 virtual machines - (1) Domain Controller (2) Application Server (just files and folders)  (3) Remote Desktop Server (for two remote users running Word/Excel)  (4) Windows 10 (only used if & when I need to do some testing). There are 8 users on the network.
 I am curious what would be best way to assign CPUs to VMs since there are two physical CPUs.
 Currently each VM has 1 virtual processors as I accepted "default value" when creating these VMs except manually assigned RAM amount.
 
Thanks.

hello,

i have tape library hp MSL2024 Fc i need to connect it to cisco ucs 240 server direct through fibre channel.

the operating system is windows server2016
the backup software is veeam
the HBA card installed on the server is emulex lightpulse HBA - storport miniport and the driver is installed.

the problem is i cannot connect the tape to the server, i fixed the speed to both to 8 Gb/s and the port type to fabric on the server and the tape drive. i swapped the cable RX and TX, still no luck

on the tape it gives me no light detected.

help please

Long story short - My client's one of the sub-companies is being sold. They were separated for a while on paper - but still were using the same IT infrastructure.
My job is to split existing company's IT infrastructure. Most of their data is mixed and stored in the same shared folders etc etc.
Since they use several Virtual Servers on HYPERV backbone - I plan to "clone" the existing servers, and when done - split the physical network.

I am thinking of using the VM replication as means of accomplishing this.
Do not have any experience with VM replication so far, but isn't this a standard for IT projects :) ?

My hope is that I will be able to bring the replicas to be "primary" after I separate the physical network, and i hope users for each company will see everything as it was before the separation.
Afterwards I plan to cleanup some files and resources that do not need to be shared, remove computer/user accounts etc.

Does it sound like a probable solution?

I have MSA 2050 with 2 Volumes (vol1 and vol2)which is connected to ESXi6.5 as datastore.
I have added 6 more HDDs on a different expansion enclosure and created one more volume (vol3)
I can see the newly created volume in expansion page. Below are the screenshots, Just want to verify I am doing right

Don't laugh!  I know about VIEW and ZenDesktop and use both, but I've been asked!  :)

I have a company with 100 users, give or take, and they want to move their stuff into a COLO and go to a VDI environment using zero clients at the office while letting the virtual desktops live in the cloud.  I've talked to them about VIEW and Citrix and we have discussed the cost.  Once the owners were released from the hospital, we met and talked some more.

I have an idea and I want peeps on here to talk it up or shoot it down and give me some feedback.

My thought is to put in a couple of RRA servers at the COLO and build one or two virtual desktops to spec, convert them to templates and then spin up my needed VMs from the template, one at a time.  We actually have two or three techs who could help so it wouldn't be horrible.  

In the zero clients, we just specify the remote gateway and the VM assigned to that user and let them RDP straight to the desktop assigned to them.

All of this would be supported in the back by 5 ESX hosts and SSD storage to handle the IOPS so I don't expect the "speed" of the VMs to be a problem.  We have 1gig from the office to the internet already so I don't expect bandwidth to be a problem.  Even the usage in the building is mostly email and internet.  The "serious computing" - that's the Solidworks CAD and the media creation - would still be done on local workstations in the building.  Those hitting the VDI would be low bandwidth users, support …

Hi,

We current have a VMware 6.5 using a Dell Equalogic PS6000 SAN as the backend storage. Unfrotunatley we have two datastores that have extents that cover two physicaldevices, so I plan on vmotioning the vms off the datastore, delete and the recreate the datastore without the extent on the other storage device. On the SAN the storage is split into several volumes used for storage. When I have tested, I have deleted and recreated the datastore fine no problems, but on the volume on the SAN any used space within the new datastore has simply been added to the in se space on the volume. The SAN has no idea that the datatstore has been recreated (I assumed that the new datatstore would be able to use upto the in use space the volume thought it had before growing the volume). I'm guessing that my only option is to vmotion the vm's onto another datastore. Delete the datatstore and back end volume on the san. Recreate the volume on the san and then the datastore and then move the vms back?

Cheers,
Paul

Hi,

Weird problem here. I've got a Windows 10 VM that used to work. But now it always fails with an 0xc000021a error. I tried to google a solution but I have failed so far :(

I've tried running sfc /scannow as well as Dism /Online /Cleanup-Image /RestoreHealth (after having successfully booted in Windows 10 by using 'disable driver signature enforcement' in the 'startup settings' of the troubleshoot menu.

Any other ideas? Thanks!

Hi, I was wondering if there was a way to use Veam Backup and restore to backup from an ESXi server and restore to a Hyper-V system.

Thanks all.

I have two 2012 R2 Servers joined to a domain and running HyperV. Both Servers are connected to a SAN via iSCSI and so there are about 8 mapped drives on each server using iSCSI initiators. The previous admin had replication going from Server A to Server B. The VM's have their storage in multiple mapped drives. We upgraded the Backup SAN with bigger drives. The previous Admin setup Replication between the two and then quit.

We failed the HyperV Replication over to the Backup Server and SAN. Everything came up fine, however when we upgraded the Primary SAN and went to set the Replication back up I can't figure out how he did it. When you set the Replication it has a field that says "Specify the default location to store the Replica Files:" under the Authorization and storage section. All of the iSCSI connections have different drive letters.

If I start a replication of VM1 and use it's storage drive letter of H, it comes over fine. But when I try to replicate VM2 with drive letter G, it goes to H as well and the VM's fill up one drive instead of going to their own drive letters and shares.

How can I set this up so they all replicate to their own storage on the iSCSI of the backup Host?

We use Veeam BU and Replication at two sites.  At site A, Veeam is on a physical machine and our backup storage is physically connected to that physical machine so adding storage to hold backups and replicas is simple.

At site B, there are two VMware hosts.  Veeam is running as a VM on one of those hosts.  

Each host has 20+TB of storage and I'm trying to add it to Veeam to hold backups and replicas and it's giving me some grief.  

Veeam is running on host 200, but the only way I have found to add storage for Veeam to use is to add a virtual hard drive to the Veeam server and then map to it.  I just want to make sure I'm dealing with this storage in the correct way.

Can anyone offer any suggestion?

Thanks

Hyper-V DDA makes me crazy.

I have installed a 2019 Hyper-V server with a 2019 server as guest - all up2date, all current drivers installe, all bios options for hyper-v are set.
I am trying to make a graphics card available to a machine via DDA.The script from https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/deploy/deploying-graphics-devices-using-dda works! However, as soon as I try to power on the VM, the hypervisor shows errors:
'NameOfMyMachine' failed to start.

Virtual Pci Express Port (Instance ID 540C1694-484B-4451-B6E7-91D6B2772D18): Failed to Power on with Error 'Element not found.'.

[Expanded Information]
'NameOfMyMachine' failed to start. (Virtual machine ID 96D073C6-E9B8-4095-96FD-E887B93C0EC5)

'NameOfMyMachine' Virtual Pci Express Port (Instance ID 540C1694-484B-4451-B6E7-91D6B2772D18): Failed to Power on with Error 'Element not found.' (0x80070490). (Virtual machine ID 96D073C6-E9B8-4095-96FD-E887B93C0EC5)

Could not allocate the PCI Express device with the Plug and Play Device Instance path 'PCIP\VEN_10DE&DEV_1C30&SUBSYS_11B310DE&REV_A1\4&25438C51&0&0008' because it is already in use by another VM.

Open in new window

Rest assured: that card is NOT in user by another VM since there is only one VM and there never was a 2nd. Using powershell, I can even determine that it is assigned to that very VM.

What should that funny error tell me?

I am going to be building a CA on a VM and the Microsoft documentation I have found seems out-dated.

What is the recommended platform for this, I have found having an offline one that is the root and then subordinates to issue the certificates as the idea. This seems really intensive.

I really just need one to issue certificates to devices/users for VPN items and HTTPS certificates for SCCM later. Nothing to intensive.

Does anyone have a good method to get one up and running quickly?
