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.

hi guys

I've got a WYSE thin client terminal. To the back of this terminal is attached a USB Skorpio scanner. On the device manager of this thin client I can see the scanner on there.

I'm using RDP on the thin client to connect to a virtual machine on our network. I would like this USB Skorpio scanner to get picked up. It isn't at the moment and I don't know whether I am supposed to do anything? I was told this WYSE thin client supports USB passthrough.

Any ideas on any changes I have to make on the virtual machine?

Thanks for helping

Hello All;

OK, I have been running VMWare 6.5 for several months now, and have moved all my sites from outside hosting to in-house.
Everything is running great.

This is what I would like to know.

When assigning hardware configurations to the new VM, the vCPU is what I am having trouble understanding.

The system is running
32GB Memory. (I think it might go to 64, will just have to test at a later date)
2 Physical Quad Core CPUs, totaling 8-cores

I have all machines assigned 1 vCPU and 4-6GB of ram.
This is an image of the CPU / Memory / Storage
VMWare ConfigurationThe above image is with 3 VMs running.
All running Win2016, with the following:
1 Web (IIS - Running 12 Sites)
1 Mail (MailEnable, running for 12 Domains, 3 contactly active)
1 SQL Server (Running 8 SQL Databases, 4 Constant activity)

How many vCPU's can I safely give to each machine?
And, the Memory, is that correct as well (4-6GB each) or can it be more?

3 Machines are LIVE, and 7 are for teaching. (I will soon be bringing in another Server, but until then, this is all I have to work with.)

Ultimate goal is to have RDS running on server 2016.  Per Experts advice, I have now re-created new physical server as Server 2016 standard running the Hyper-V role; created 1st vm as serverA running Server 2016 with roles of ADDC, DNS, DHCP; 2nd vm as serverB with Server 2016 and attempting to add RDS role quickstart deployment.  I see this server but it states that cannot deploy because "unable to connect to server by using Windows Powershell remoting".  Both servers are in same domain, can see one another, have only 1 user, administrator, so far, firewalls on both are turned off, tried Powershell Enable-psremoting -force on both.  I am new to virtualization and don't know if I have missed steps in the setup of these 2 servers that would cause this issue?  Are there networking issues I am missing?  Where do I go from here?  Any help is appreciated.

Hello

I connect to a remote computer with an IP Address of 10.x.x.x via Cisco Anyconnect Secure Mobility Client on a Windows 10 pro host with IP Address of 192.168.1.xx. I need a virtual machine with Windows 10 Pro (VM Workstation) currently IP Address of 192.168.1.x on the Windows 10 Pro Host to access that computer. I can ping the remote computer on the Host, but not on the vm workstation. I tried installing the Cisco Anyconnect Secure Mobility Client on the VM, and it connects, but I still can't ping the remote computer. I tried setting tweaking the VM Workstation's network adapter to Bridged, Bridged with replicate physical network state, NAT, Host Only, but no ping. I turned off Firewalls on Host and VM....

Thank you!

I am trying to figure out how to re-allocate space on a new VM installation for a server.  I need a C drive of around 100gb and the rest a D drive.
I can't seem to determine where this is done.  I am going back to the VM installation and do not see an area to do that.  If I need to trash the installation and do it over I can.

Our Vmware environment consist of a Winodws 2012 R2 vCenter Server Running vCenter 6 Update 3 and 110 ESXi 6 Host Running ESXi 6 Update 2 and all of which are IBM x240 blades using the same Emulex driver version. Our backend storage consist of three IBM GEN3 XIV's connected via FC and FCoE. What I have noticed is that storage vmotion and Template deployments are taking much longer than normal. For example, a coworker was deploying a VM from one of our temples which is same and under 60GB took 40 minutes to complete. What was strainge is that it crawled throughout the entire process then when from 70% to completed. Also I am do storage vmotion down and they are slow as well. When I checked the VMKERNAL log and search for one of the device id's I am migrating from I see the following:

 "NMP: nmp_ThrottleLogForDevice:3298: Cmd 0x89 (0x439e001a5c40, 26417684) to dev "eui.00173800337707f5" on path "vmhba1:C0:T13:L3" Failed: H:0x0 D:0x2 P:0x0 Valid sense data: 0xe 0x1d 0x0. Act:NONE"

Our SAN's are not overload and had our storage Admin check. I feel this is storage related since deployments and storage vmotions are slow. Yet general VM performac overall seems ok. Thoughts??

I have a 2012 Server R2 Standard Hyper-V VM (Server1) that has Remote desktop services with all the roles on it. This is for Published Apps. I setup a second Hyper v VM (Server2) to replace Server1. I access Server1 by going to http://rds.domain.com/rdweb and the cert is for rds.domain.com. I can access this fine and open the apps.  I access Server2 by going to http://access.domain.com:8443/rdweb and the cert is for access.domain.com this is a self signed cert for now. When i go to http://access.domain.com:8443/rdweb and login and run an app i get this error " Your Computer cant connect to the remote computer because the remote desktop Gateway server address requested and the certificate subject name do not match." If i select view certificate i see the Server1 cert rds.domain.com.

I think this has to do with port 3389 and that when i launch the app its pointing to the server1. Is there a way to change the port on Server2 if this is the issue?

I have a 2 way trust relationship between 2 domains\Forests.

User1 (from Domain1) tries to access a server ABC in domain2. In fact I am testing in domain2 and i try with user1 to RDP a server i have here (domain2) ==>very slow (45 sec)

Now when i use the same user1 to login that same server ABC through Vsphere ==>super fast (less than 6 sec)

Of course ABC is a VM machine!

Any ideas? This is driving me crazy!!!

Thanks for the help.

I'm curious about opinions on actual experiences with Veeam Failover/Replication vs VMWare's integrated solution.
Preferably from people who have done both and some Pro's and Con's, overall experience etc.

We already have Veeam and I'm quite happy with it for backups, but I'm not 100% sure about it's failover capabilities.

In vCenter 6.5 appliance, 2 Dell R710 hosts with 6.0 i created a distributed LAG for iscsi. I added the hosts and their NICS to the group.  I then configured the iSCSI port groups to use the LAG as Active Uplink. After that, it seems that the Host Storage Adapter no longer can make an iSCSI connection.  I am confused on where the problem is and what to do next.

14 Hyper v hosts, managed via SCVMM running on a c7000 blade chassis with 10G interconnects - All intel CPU's, 192 GB RAM etc. Broadcom nics but vmq disabled.

Dell 10GB switch managing ISCSI to the chassis and SAN.

IBM v3700 with 2 expansion trays.
5x400GB SSD's in raid 10 for easy tier, 4 x raid raid 6 arrays of 10k disks. (lets call it 8 disks each array) 1 x large Raid 6 of Nearline drives.

The environment is well loaded and runs fine running a varying number of VM loads.

We monitor extensively all performance etc and know that there are no issues with CPU, memory or disk access etc UNTIL:

If a backup is misbehaving, someone is doing a high disk load activity or something like deploying a templated VM, all users across all VM's notice a slowdown or lockup.

DISK IO on the SAN is neligable, Ram usage, CPU Usage does not spike and there only a small increase in the amount of network traffic.

It seems like everything runs well, but just a small event can cause issues.

Looking for ideas, configuration changes or otherwise.

I'm using the free version of ESXi 6.5 and don't have Vcenter.
Is there a way to give a user user access to just one VM through ESXi? I try the ESXi web and client and I can setup users and some permission but it seams i can not limit the access to just one specific VM.
Any help appreciate - Thanks

Our company just purchased another and I have some questions regarding their existing VM Setup.

Thier setup
2 Physical Servers running HyperV, 50 Windows VMs
4 Physical Servers running a mix of vCenter, vSphere 5 & 6.  100+ VM's running Windows and Linux.

My questions
1.  I am not that familiar with HyperV, I'd like to convert these to VM to unify the setup.  Is this a difficult process?
2.  Will I have limitations in the future with vSphere?  Meaning, will I not be able to install the latest Windows OS?
3.  If I were to buy new hardware, could I reuse the vSphere 5 & 6 licenses?
4.  Any limitations that you see that I'm not thinking about?

The idea is to get everything uniform so my team isn't pulling out their hair all the time.  I feel like we are taking over this infrastructure from someone who knew little and had a very tight budget.

I have a dedicated block of IP Addresses here (32 IPs) and have a windows server running on one of them. Virtual box is installed and works well withits DHCP Served address from the Virtual Host Manager 10.1.200/24 for the VMs. I'm fining myself now needing to expost a VM with a public address for email server and some other services - trying to get rid of an OLD (ancient Ubuntu 12x) server with a new Ubuntu 18 VM system. Its VERY low load and use.
32 bit Intel(R) Xeon(TM) CPU 2.40GHz so not alot of horepower needed and 2GB RAM. The windows box is 64-bit 16GB RAM and 4 Cores (8 logical procs Intel i7 at 3.2GHz).

What do I need to  do to Virtual Box to let it work with real addresses and not the DHCP Assigned ones from Host Manager? I'm sure its simple buit I haven't been able to locate the answer.

THank you,

Hi, i cant seem to mount a VHDS (Shared VHD set) on any of my blades.

Over the weekend i migrated my SOFS cluster to 2016 from 2012 R2, i have upgraded the functional level of the cluster as well.

I have moved some machines back, and it all works good. However i want to try and use VHDS to create a file server cluster.

I have created a new VM, installed Server 2016 on it and got it fully up to date. In settings i add a new shared VHD and it then goes and creates the 2 files, however when i try to attach it it says "Failed to add Device"

In the event viewer i can see the below, but i have checked permissions of the VHDS / AVHDX file and the machine has permissions.

'Test' cannot access the data folder of the virtual machine. (Virtual machine ID EB43A89F-4AE6-4AB6-825D-C0878EC0020C)

'Test' failed to add device 'Virtual Hard Disk'. (Virtual machine ID EB43A89F-4AE6-4AB6-825D-C0878EC0020C)

Any help is appreciated.

It seems that the documentation about IPsec/IKE setup on an SRX to Azure s2s VPN is conflicting.  There are 3 pain points:

1.  Can IPsec/IKE be used on a policy-based VPN for Azure? It seems that Azure is clear about "no" but the suggested Azure config includes IPsec & IKE config
2.  Which IKE version is best for SRX to Azure - v1 or v2, when using Policy Based or Route-Based VPN? (see attachment)
3.  If a trust sec zone (internal interf.) and an unstrust sec. zone (exter. interf.) already exists, how can I add interfaces that are in one of those zones already to a new "Internal & Internet Zone" for the Azure VPN Tunnel as documentation suggests?  I receive an SRX error about adding interfaces to multiple zones prohibited and if using PB VPN there is no st0.x to that config and/or I don't understand how to utilize or place the traditional interface under the st0.x iface.

SRX ERROR:

commit check
[edit security zones security-zone Internal]
  'interfaces ge-0/0/1.0'
    Interface ge-0/0/1.0 already assigned to another zone

I found this on Azure's site - https://docs.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-ipsecikepolicy-rm-powershell

When trying to connect to a VM through Hyper V manager getting an error "An authentication error has occured (Code: 0x8009030e). Remote Computer : Server1.domain.local" and another error right after "Cannot connect to the virtual machine. Try to connect again. If the problem persists, contact your system administrator. Would you like to try connecting again?"
I can remote into the VM through RDP and i can connect to the host through another Hyper V manager and connect to the VM. Seems to be a UA issue on the host of that Vm. Any ideas?

Good evening,

I am currently presenting problems in my vCenter Quality-Development. The following message appears when I enter the vCenter (Image 1). Where I can not visualize the vm, datastore, Host, of both environments. (Image 2).

I entered my server Windows Server 2012, to validate the vCenter services, and note that the vCenter Server service and together with the VirtualCenter Management WebServices service, do not start, since they depend on each other. You can even see that they are waiting to start. (Image 3 and 4).

Validating the log in the vCenter folder, it tells me the following error:

"error 'utilvpxdVdb'] [VpxdVdb :: SetDBType] Failed to connect to database: ODBC error: (08001) - [Microsoft] [ODBC Driver 11 for SQL Server] TCP Provider: No connection could be made because the target machine Item.
-> Retry attempt: 1 ... "

The error indicates that there are connection problems with the vCenter database.

Validating the connection in the ODBC, performs a Test Connection test and there is a connection failure. (Image 5).

I spoke with the Database team, and they tell me that the instance that points to the vCenter is below, which is why the service can not start. Our vcenter points to the Quality instance.

The Database team recommended that I point the vCenter to the Development instance. Obviously to do this, you should reinstall the vCenter to select the new instance. Is this a recommended practice? What could be the consequences?

What …

Please excuse the basic question, but I'd love to have someone just spell this out for me.

I wish to install a terminal server style of installation where I have virtual images of either a personalized-to-the-user-profile version of Windows 7 desktop or a generic Windows 7 desktop that resets after each use. I cannot use the server desktop as a OS as we have some legacy software that won't run properly through a server OS.

I feel like this is called VDI, but every time I pursue information on a XenDesktop or RemoteDesktop solution and how I'd go about it, my readings suddenly shift from what I am envisioning to a solution based off of using a server desktop. I am sure I am missing something, so I would appreciate if someone could just point me in the right direction.

I want this to serve as a utility for remote users now, but also to double as something I could restore at an off-site virtual farm to provide desktops for our users in the event of a disaster. (I am already set to restore my VMWare based servers in this way) I thought that logically this would best be done with the VMWare virtual desktop, or Citrix Xen Desktop, but I would love for someone to tell me where I am going astray in my reasoning and point me in the right direction of research.

Thanks for your help!
