Since 2 months we are trying to configure a VM so that it runs a special SQL application inside a VM with acceptable performance.

The vendor of that software tries to sell their software as a service hosted in their own datacenter but we wiyld prefer to host it ourselves.

The problem is that we dont get a decent performance even if we run it inside a VM with moret than good enough specs - at least on paper.

Now we noticed that if we run the same application in an old desktop system inside a VirtualBox VM we even get better performance than in a fat VM hosted on ESXi 6.7

The deciding factor seems to be the CPU.As soon as we use a host with a single socket CPU performance is acceptable.

When we use a CPU with 2 or more sockets the performance is unacceptable.

So my question is: is there a way to make any CPU (for example any XEon or Opteron) look as if it had only one socket ?
The number of cores apparently seems to be no problem.

Thanks

Hello,

I wish to know if it is feasible to have the main site with 3 hosts and vSphere Essential Plus license and another DR site with vSphere Standard and enable replication between these sites. What will be the issues if I do such a setup since I see that most people have advised to have Essentials Plus on both sites.

Thank you.

I am using a mac to work from home, logging in remotely to Windows using VMWare Horizon but can not get the microphone to connect when using Zoom

Can anyone help please.

Using WMWare Client to log into work remotely (WINDOWS). Trying to use zoom for meetings but not connecting to the microphone. Request not being made to or recognised by IOS - not sure which one of those. Just know that when checking the microphone permissions in Privacy there are no apps showing as requesting access.

Can anyone help please?

Hey all,

I was recently asked to report on active UAG sessions so we could see peak times for external users with the recent COVID-19 remote work extravaganza. I came up with a PowerShell function to do so. Just pop this into a .ps1 file, open up PowerShell and execute it, and then Get-UAGSessionCount will be available as a commandlet for you to run.

Example:

Get-UAGSessionCount -username [UAG username] -password [UAG password] -UAGHostName [hostname/IP for your UAG management interface]

You will simply get a number back that shows the number of authenticated sessions. I essentially took this output, combined it with date/hour, and continuously export it to a text file to report into PowerBI so we have a real-time dashboard of our UAG stats.

Hope you enjoy - note that the API is not available until v3.5 as far as I know. I attached the ps1 to this post.

Hello, I'd like to run the following PS script under a domain\service account which is a local admin on the machine.

The problem, I am having with the below script, that it needs to be logged in ie. load the user profile of the user in order to register all the services etc.

I found one example that Luc has provided, but I can seem to figure out how to make it work.

$script06 = 'Configure_XD_SiteA.ps1'

$ISOpath = 'D:\Deploy\Applications\Citrix\XenDesktop'

$fullpath06 = join-path -path $ISOpath -childpath $script06

$CTXServiceUser = "CTXLAB\Service.vad"

$CTXServicePWord = ConvertTo-SecureString -String "VMware1!" -AsPlainText -Force

$CTXServiceCredential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $CTXServiceUser, $CTXServicePWord

Write-Verbose -Message "Configure XenDesktop Site." -Verbose

Invoke-VMScript -VM $vm -ScriptText $fullpath06 -GuestCredential $CTXServiceCredential -ScriptType Powershell

Many thanks!

Hi

Anyone has experience with Cloud Flare load balancing the VMware Horizon Security server. We are trying to get it working but doesn't work as expected when it's in proxied mode but works well when it's not in proxied mode.

Currently, we are just testing with one URL and trying to route traffic to that from the LB URL. I have previously done with Netscaler and Kemp had no issues.

Example

LB Url: testaccess.domain.com

Sec Servers Url : access.domain.com

When we try to access test access we have noticed 2 behaviors

1) Login Screen in loop

2) Failed to resolve proxy route

But if I hit access.domain.com directly both HTML and client access works fine. in the Sec servers and Connection servers we have chedkOrigin=false.

The External URls in the Sec servers are access.domain.com I have also tried using testaccess.domain.com same results

Please Advice.

I have blueprint with custom forms activated with the 'disks' data grid shown in the form which allows end users to add disks and modify the properties. This is great for allowing the users to choose their Storage Reservation Policy on a disk but I would also like to allow the user to set custom properties on the disks. There is a field called custom_properties but I have no clue what format the properties should be in and when I do attempt to put different properties in the field they don't show up in the virtual machines properties. Does the custom_properties field have any effect?

Hi All,

Having an issue after deleting some snapshots on a VEEAM Replica VM

I have studied VMware Knowledge Base on the error but Im not sure how to proceed in my situation.

Below is an extract from my VMware.log for the machine in question,

Would someone be able to give me guidance on what files I need to modify the CID on ?

Thanks in advance

Hello,

I recently switched over to using Ubuntu 18.04 LTS on my desktop computer. I installed VMware Workstation Pro 15.5.2 and have run into multiple cases where any of the guest VMs I run (Windows 10 or Ubuntu 18.04) cause my entire computer to freeze. The system becomes completely unresponsive and I have to hard reset with the power switch to recover.

I'm only running supported versions of guest operating systems and of course, Ubuntu 18.0.4 is a supported host operating system for VMware Workstation Pro 15.5.2.

Obviously, if I happen to be working on anything that wasn't saved at the time the host freezes up, it's completely lost!

I've tried switching the VM Tools in my Ubuntu 18.04 guest from open-vm-tools to use the official VMware Tools for Linux and the Windows 10 guest is running the most up-to-date version of VMware Tools that comes with VMware Workstation Pro 15.5.2.

I removed VMware Workstation Pro 15.5.2 and installed Oracle VirtualBox 6.1 instead. I don't experience the system freezes so there's definitely something awry with VMware Workstation Pro.

I found a few articles online that recommended a variety of changes including:

1. Forcing VMware to rebuild the kernel modules:
   1. vmware-modconfig --console --install-all
2. Switching from open-vm-tools to VMware Tools (as mentioned earlier)
3. Limiting the amount of physical RAM available to virtual machines (host has 24 GB of RAM - I restricted the total amount available to VMs to 12 GB). I only had one VM running at a time and the maximum amount of memory allocated to any guest is no more than 6 GB for Windows and 3 GB for Linux
4. Disabling khugepaged defragmenting:
   1. echo never | sudo tee /sys/kernel/mm/transparent_hugepage/defrag

I'm at a loss for what else to try. I rely on VMware Workstation, vCenter, and ESXi for other aspects of my job. Using Linux on my desktop has been an amazing change but not having Workstation is severely hindering my productivity!

Any ideas?

Thanks!

Hi,

I have Workstation 15 pro (15.5.2) installed on Windows 10 (1803). I have multiple guests of different OS' running, all having the same issue.

Capturing network traffic, I can see the DNS requests going out, but no responses coming back. Running nslookup on the guests results in a "DNS request timed out", regardless of which DNS server is specified. The host has no DNS issues and when I switch the guests to NAT everything works fine but I need to bridge. This started happening after I installed the most recent update. I tried re-installing, made no difference.

Any thoughts or insights appreciated.

Thanks,

Eamonn

Hello everyone!

After some searches online I was not able to find an answer to my issue. On every power loss on my vSphere machine all the guests get corrupted and it's necessary to perform a repair to the .vmdk file through ssh.

This is a small home server and it's very frequent that it experiences power loss. I was using Hyper-V before and never had this corruption problems.

What do you think could be the issue? The corrupt every single time there's a power loss.

Version: 6.7.0 Update 3 (Build 15160138)

Thank you

New to this....so please help!

I am trying to console to Linux server thru ESXi and all I get is a blank screen.  There is nowhere to login.  I can ssh to the server and the database is fine.  I'm not a linux expert, so any help is appreciated!!  ThankYou!

Hello everybody,

I have a VM with windows server 2016 running as a file server for my organization. At the beggining of the VM construction I configure much more space from the datastore than I will ever need. The extra space is in offline partition and I want to know if there is a way to reclaim this space back to the datastore. The datastore is stored in an external storage (dell ME4012) and the esxi is on version 6.7. There is also a vCenter appliance managing the esxi host.

Thank you.

Per my own testing and posts in this forum, the root account becomes locked after 4 failed attempts.

If I understand correctly, the way to recover the account is to first reset the password via the process in KB52652.  Then, the account must be unlocked manually with this command, per this post:

/sbin/pam_tally2 -r -u root

We have automatic security scanning systems in place which periodically test common passwords against all of our systems, to ensure that nothing is using a weak or default password.

This effectively means that we have to use this onerous password reset process every time that we want to login to the root account, since it'll have been automatically locked out.

This does not happen with ESXi, vCenter, vROPs, LogInsight, etc. appliances.  Either the account does not get locked out, or is automatically unlocked after some time interval.

Please update the Skyline appliance to match the behavior of VMware's other appliances, or let me know if I'm missing something.

Thanks!

Hello,

I am trying to setup a Distributed Switch with 4 VMs using the RDMA feature without a HCA adapter on the same Hypervisor with ESXi 6.5 Update 2 (earlier fix for this kind of problem should be included).

The VMs are running Redhat RHEL Linux 64-bit with kernel 3.10 and hardware level 13. The PVRDMA adapter is recognized by the OS in all 4 VMs.

When running ibstat -v the State is set to "Down":

CA 'vmw_pvrdma0'

    CA type: VMW_PVRDMA-1.0.1.0-k

    Number of ports: 1

    Firmware version: 1.0.0

    Hardware version: 1

    Node GUID: 0x00505600008b4b52

    System image GUID: 0x0000000000000000

    Port 1:

        State: Down

        Physical state: LinkUp

        Rate: 2.5

        Base lid: 0

        LMC: 0

        SM lid: 0

        Capability mask: 0x04010000

        Port GUID: 0x025056fffe8b4b52

        Link layer: Ethernet

Running sminfo fails with:

ibwarn: [33392] mad_rpc_open_port: client_register for mgmt 1 failed

sminfo: iberror: failed: Failed to open '(null)' port '0'

Any idea, why the State is "Down" or if any additional undocumented steps need to be performed for the PVRDMA adapter when no HCA adapter is used?

Thank you.

Hello all,

I have been going crazy over the long logon times in my environment. I've had support tickets opened and closed with numerous finger pointing occurring. My own profile can take upwards of 4 minutes to logon, and I've narrowed it down to the notorious google chrome UEM archive (a whopping 103 megs)

I have removed all AV agents, I've rebuilt the image, and I've even tried a new build but it all seems the same. I've re-reviewed the OSOT settings to ensure there is not something related to unzips/extracts. Has anyone has success here?

Hi Guys,

I've recently deployed a UAG (3.9.1) on my DMZ for my users and I have a couple of questions regarding its behavior. We're using PCoIP only, and not BLAST.

1. I noticed if I disable HTML access in the UAG under the Horizon settings, and I enable HTML access on a random desktop pool in Horizon, I can log in through the UAG using Horizon HTML Access and see the enabled pool. Is this the expected behavior or is something configured incorrectly? Again, HTML access is disabled on the UAG.

Is there a way to brand the landing page of the UAG? If possible, I would like to remove the links to the VMware downloads page and the HTML access links, and just have our company logo.

Thanks!
