Con1924 Posted May 25, 2020 Share Posted May 25, 2020 (edited) Hi, I am wanting use a vmware vm inside a windows vm. I have followed the spaceinvaders video however I keep getting an error when trying to start the VM. "VMware Workstation unrecoverable error: (vcpu-0) vcpu-0:VMM fault 13: src=MONITOR rip=0xfffffffffc01a792 regs=0xfffffffffc407e50" I want to nest VM's like this because I have licensed software I use for work on the VM's and i find the unity feature very useful. An alternative way of using the VM's with an alternative for vmware unity would also be okay. Thanks in advance. Edited May 25, 2020 by Con1924 Quote Link to comment
PureAmnesie Posted January 17, 2021 Share Posted January 17, 2021 (edited) Hello, I have the same issue and didn't find any help on the matter. Does someone have an idea? [Edit] It seems to be an issue for all types of nested virtualization on windows. I tried to install Hyper-V feature on these OS: Windows 10 Pro Windows Server 2016 Windows Server 2019 Datacenter Edition Fully updated, including drivers. But always same BSOD when restarting the VM to finish installing Hyper-V: "hypervisor error"... However, an ESXI will allow running multiple VMs simultaneously! But these VMs doesn't work properly though, I cannot run Windows update (always an error after a few minutes) neither installing applications (nothing append after allowing system modification). But at least VMs are running! If it can help, I run my Unraid (v6.8.3) on a 1950x AMD CPU / Gigabyte x399 Aorus pro Edited February 23, 2021 by PureAmnesie Quote Link to comment
Fragsrus Posted January 27, 2021 Share Posted January 27, 2021 I have also been searching for a solution to this error. I have two VMs that I am trying to run for school and would much rather work on my main system than splitting work between the main system and my laptop. Quote Link to comment
n3cron Posted May 3, 2021 Share Posted May 3, 2021 Im new into this, and cant wait to setup my own Unraid-System. However, as far as i do understand Unraid it trys to Bare-Metal as much is possible to its VM. I would try to bypass as much possible to VMware and enable Intel or AMD VT-x on the CPU if not already done. You shuld also try to bypass a hardware drive to VMware to have its own "bare" installation on a datadrive, while the virtual drives might be able to run on your Storage cluster/Caches. As for Windows there might be a difference if you install it on UEFI emulation or CSM/MBR/classic. Checkout different VBios versions.

If we pretend that KVM Emulation ist close to Baremetal but its still a Virtualization HOST. https://www.pcsteps.com/508-nested-virtualization/ A Third Layer is already very demanding. KVM->VMWARE = 1 Layer VMWare->Windows OS = 2 Layer Windows OS => Hyper-V 3 Layer. On 1/27/2021 at 7:37 PM, Fragsrus said: I have also been searching for a solution to this error.

You can have all others installed on unraid and switch to them by VNC /RDP through your machine. You dont need to hyper-V them. Run the Windows 10 Host Machine and connect to other machines by RDP/VMC/SSH depending on demand. You are allowed to have multiple RDP sessions with your Host Machine. You can give them one "shared" space which all are connected to if you need to transfer files between. ->other Windows OS Windows 10 RDP/VNC -> Server 2016 -> Linux VM But they all run on the Virtualization of unraid. I Hope this should fix your Issues. Quote Link to comment
