Hi All, I have a Windows 11 machine with an Intel i9-12900K running Windows 11 Enterprise 21H2 - I was trying to create a Windows 11 Enterprise VM and the performance was abysmal. After some web searching, I found a post that seemed to indicate that changing the client virtual disk from NVMe to SCSI dramatically improved the performance. Using this I can confirm that it really does make a difference so I'm wondering if there is something in the configuration of my host machine that would cause this to manifest. Does anyone have any thoughts or insights? Thanks.  

Hi All, I just set up a NAS and I'm wondering if anyone has a guide/best practices/etc for using the NAS to store the VMs (Workstation Pro 16.2 based). In an ideal world, there would be some way to open the VM and have it download from the NAS, run locally, and then when closed pushed back to the NAS. I'd assume this is the most performant way to use my PC (i9-12900K, PCI-E 4.0 NVMe SSD) but it seems that I need to do this manually. Alternatively, I've just moved over to a 10G Ethernet network so I could run the VM from the NAS but this does seem slower than running it locally so I'm wondering if maybe there is something I need to configure or there is a different way to set up the VM so this is faster (iSCSI/LUN/etc). If anyone has comments/suggestions/guides I'd really appreciate the education. Thanks, TonyG

Hi All, I've just download the trial for VMWare Workstation (it's the current version 12.1.1 build-3770994) as I'm thinking of buying a license to help automate some of the old HP test gear I have here at home (they have automation software that expects to have a MSDOS machine). So far I have MS-DOS 6.22 installed on the VM and everything seems to be working but I'm running into a problem getting the serial port configured to work with the National Instruments GPIB drivers. Because this is all old gear, I bought a GPIB-232CT-A RS232 to GPIB adapter. I've tested this setup using a really old laptop I have here and it works but when I try to get it working from my main PC under VMWare it seems like the software can't communicate via serial. At the point where the software on the laptop would start talking to the serial device the VM seems to hang/take much longer than expected before it fails out (unfortunately without an errors so no helpful debug info there). On my main machine here the serial port is actually an additional PCI-Express card and surfaces as COM5 & 6 - This card works as I'm using COM5 to talk via serial to my GPSDO. I've configured the VM to have a serial port and I've tried to follow the suggestions in various posts but it doesn't make any difference. SO I thought I'd ask the community for help. Here is the relevant part of the VMX file: serial0.present = "TRUE" serial0.fileType = "device" serial0.fileName = "COM6" serial0.tryNoRxLoss = "FALSE" serial0.autodetect = "FALSE" I've attached the VMX to this post - If anyone has any suggestions I'd really appreciate the help as I'd like to get everything running on my main desktop instead of almost 20 year old laptop machines. The GPIB drivers are the CTDOS27 ones from National Instruments. Thanks in advance and apologies if this is a trivial question that is well documented somewhere that I couldn't find. TonyG
