Bug in ESXi 6.? when handling VMDKs created by Workstation

This post was originally published on this site

Some versions of ESXi 6 do not treat VMDKs created by Workstation correctly.

To be precise this is about the format



That format when it is accepted by ESXi comes with a text descriptorfile plus one large file typically named name-s001.vmdk


Warning: this format will prevent automatic backuptools from doing their job and it also prevents you from merging snapshots back into the basedisk.

The behaviour is inconsistent !

ESXi should either (preferably) deny using this format in the first place – which is the intented behaviour – or it should be able to handle it correctly : including the function of merging snapshots.


Most probable reason why you may have this vmdk-type at all on ESXi is manual imported VMs from Workstation or Fusion when the admin is not aware of the inconsistent treatment of this vmdk-type.


According to the VMware documentation this should not happen !

suspend (freeze) a machine in RAM instead of creating memory dump into hard disk

This post was originally published on this site

I know there is no such an option, but it is possible to request such an option?


leaving the machine on is not a good idea cause the VM sometimes will start tasks on IDLE (esp windows) and that will slow down the host,


And I am using SSD, creating 16GB memory dump every time I want to suspend my machine will kill my SSD


Is it possible to add an option to mimic virtual box “pause” option will just pause the machine in RAM?



Why did JMP get discontinued?

This post was originally published on this site

I’m having difficulties as to why the JMP(Just in time platform) is no longer in use in Horizon 8. Anyone know why?


I found it quite nice to be able to manage and maintain departments one by one. But since Jump is just a bundle of.xml configuration files. Will i be able to utilize them somewhere else? For example DEM?


What products are similar to JMP?


Am i maybe misunderstanding the statement?



Error connecting remote USB device

This post was originally published on this site

I have a Windows host and a remote Kali Linux guest (via vSphere, the reason I put this question to the Workstation section is described below). The remote guest is accessed via VMWare Workstation Pro 15.5.6 build-16341506.



My problem is: I want to connect my Google Pixel to the remote Kali guest.



The remote USB connection always works on the first connection, but when I unplug the Pixel or restart my host or the guest and then try to connect the Pixel to the remote Kali guest again (VM -> Removable Devices -> Google Pixel -> Connect (Disconnect From Host) ), I always get the following error:



Error connecting remote USB device: The device “Google Pixel” disconnected: a connection error occured.





Why i suspect this to be a Workstation issue:

I already figured out that when I run the Workstation 15.6 installation EXE, choose “Repair”, let the repair finish and then restart my host, the problem disappears and I can connect the Pixel to the remote guest — however again, it only works until I either disconnect the Pixel or restart either my host or my guest system.





How do I get rid of this problem? Is there a better way to than to Repair the Workstation installation every morning?



Thank you for your advices.

can I user the linux agent on a physical server to create a multiuser desktop pool?


BTW, is the the correct syntax for installing in multiuser mode this one if you have a stand alone VM/server?


./install_viewagent.sh -A yes -M no -b connection-server.fqdn -u adajoinuser -d domain -n machinename  -k domain-controller.fqdn –multiple-session

I’ve installed Ubuntu 20.04 guest on Windows 10 host and OpenGL 3.3 version is reported. I’ve updated Mesa drivers to latest version (20.1.8) and the same OpenGL version is reported:

PS: I’ve also tried this guide https://docs.mesa3d.org/vmware-guest.html to build vmwgfx, but it seems outdated.
