What’s the safest tool for running not safe soft – VirtualBox vs Windows Sandbox vs Hyper-V

I’d want to ask what’s the safest environment to run potentially not safe software?

I’m aware that this question may be very tricky, because every of those may have its flaws, but generally speaking which of those 3 sounds like safest option?

Hyper V – Windows 10 as host & guest

Virtualbox – Windows 10 as host & guest

Windows Sandbox?

Cannot set up network on Windows 10 Hyper-V Ubuntu VM

Trying to create an Ubuntu 18.04 VM (server) on Windows 10 Hyper-V. I’ve done it before, but it is not working now. I’ve tried “generation 1” and “generation 2”. I have a “default switch” set up and working for other Ubuntu machines. I have turned off my Windows Firewall to attempt to beat this problem.

What do I need to know?

Gerenciador do Hyper-V

Olá. Eu fiz a instalação do Docker na minha maquina e segui todas as especificações do software só que não tá funcionado.Eu verifiquei o Gerenciador do Hyper-V e a maquina virtual do docker tá desligada eu não consigo ligar e estou recebendo a seguinte mensagem : inserir a descrição da imagem aqui

Como já disse antes eu segui as especificações, e tambem a virtualização da Bios esta habilitada.Eu queria saber o que pode esta ocorrendo para haver este erro?

How to set 6 physical, 6 hyper threading total 12 cores to hyper-v virtual machine – A parameter cannot be found HwThreadCountPerCore

I have windows server 2012 R2 on physical dedicated server

I have created a virtual machine via Hyper-V and installed Windows server 2019 in it

My dedicated physical server has 12+12 total 24 cores

12 core is physical and 12 core is hyper threading

From dedicated server’s hyper-v interface, there is no option to set how many physical cores and how many logical cores for the created virtual machine

So I am trying to set number of threads per core via the command below from powershell (running as administrator) in the dedicated physical server

Set-VMProcessor -VMName aa -HwThreadCountPerCore 2 //aa is the name of hyper v machine

However this command is giving the below error but it should work

What is the error and why it is not working?

How can i set X amount of physical cores and Y amount of logical cores?

    Set-VMProcessor : A parameter cannot be found that matches parameter name 'HwThreadCountPerCore'. At line:1 char:28 + Set-VMProcessor -VMName aa -HwThreadCountPerCore 2 +                            ~~~~~~~~~~~~~~~~~~~~~     + CategoryInfo          : InvalidArgument: (:) [Set-VMProcessor], ParameterBindingException     + FullyQualifiedErrorId : NamedParameterNotFound,Microsoft.HyperV.PowerShell.Commands.SetVMProcessorCommand 

This command has worked on my personal computer which is Windows 10

Hyper-V Server 2016: Not able to automatically grab IP addresses for VMs on a VLAN that is set up with IP Helpers

I’m quite new to this whole thing, so my apologies if my understanding of virtual networking is a bit lacking.

I have a Hyper-V Cluster (Server 2016) and I’d like to be able to configure VMs that I set up on this cluster via DHCP. I’m using an external vswitch with these VMs that is set up with a specific VLAN ID. This particular VLAN is set up with a DHCP scope and IP helpers.

The problem is that these VMs are not automatically grabbing IP addresses even after enabling DHCP on them. I can manually assign IP addresses from this subnet and they work just fine, but the VMs won’t just ‘grab’ them. If I don’t manually assign an IP address from that range, it will just be assigned APIPA address. Again, the subnet is set up with IP helpers, so in theory I shouldn’t need to set up a DHCP server on this VLAN (or at least that’s my understanding).

What would you suggest I try next? Or what additional information can I provide?

Thanks!

Mouse and keyboard not working in Hyper-V connection after mirgating VM on other host

I’ve create an 1st generation VM with Ubuntu 18.04.2 on Hyper-V Windows 10, it work properly. Then, i clone VM by the export/import VM in Hyper-V menus. When i start VM on other host – it started and work, even I can connect to it over XRDP session, but if i try to connect it with usual connect from Hyper-V dispatcher I’ve see full process of loading console session, same on original host, but mouse and keyboard no work in it. If i clone so way Windows 10, for example, all clone connect using usual connect to VM from Hyper-V dispatcher without so problem. I suspect it happens because the Ubuntu can’t detect that HAL was changed and not expecting the mouse and keyboard on other places. I’ve tryed to reset VM but in vain. How to force Ubuntu rebuild HAL?
