Has anyone else noticed Virtualbox since 7.2.x becoming extremely unstable when it comes to running "modern Linux guests" (like Ubuntu 24.04.LTS)?

(The host is a 64GB Windows 11 machine with only one or two guests running at any given time. None of the guests are given more than 16GB, sometimes it's 6-8GB.)

Does anyone here run a fully encrypted #ProxmoxVE installation and can share their experiences? Going for a full #ZFS installation with encrypted pools looks like a likely variant...

#Opensource #virtualization suite #Proxmox delivers #DatacenterManager beta that makes it a more viable #VMware contender
Proxmox’s main offering is Virtual Environment (#PVE), hyperconverged infrastructure that allows users to run and manage #virtualmachines and #containers
Datacenter Manager has been developed with objective of providing centralized overview of all of your individual nodes and clusters. It also enables basic management like migrations of virtual guests.

When you are running a VM using QEMU/KVM, are the resources you allocate to the VM (ram, CPU cores etc) still available to the host machine? If so are the resources dynamically allocated as needed to the VM?

In the past, I recall successfully running DistroBox and Podman with VirtualBox.

However, this setup doesn’t seem to work well on NixOS. While it’s possible to get VirtualBox working with QEMU (albeit with some difficulty), the performance hit is substantial.

I've improved the virtualization options.

The user is guided through the choice of using DistroBox and Podman. If they select that option, they are advised to skip VirtualBox and instead use the optional "Virtualization stack: QEMU/KVM + libvirt + GUI tools," which I believe I've configured to work just as well as VirtualBox.

Although, as always, feedback is welcome.
