    batocera linux installation

    I imaged Batocera to a USB using Etcher, built a basic VM (config below) using VirtIO Block for storage, including the usb device on the host, ensured boot order was set to virtual storage first then USB, followed Batocera's instructions to install to 'Internal Disk' using these instructions...

    Nested Hyper-V Virtualization Inhibits VM Startup

    I believe this is now resolved. Hoping the same for others. My setup: CPU: AMD Ryzen 3950x L0 - Proxmox L1 - Windows 11 guest w/ Hyper-V enabled L2 - Windows 11 nested guest (i.e. a vm created from Hyper-V in L1) Previously my L1 guest would lock up with CPU spiking to 100%, it no longer seems...

    Great to hear! Any special configs on your L1 VM (to get Hyper-V working) ?

    Nested Hyper-V Virtualization Inhibits VM Startup

    Still tinkering - no luck yet. It freezes even after manually adding in Hyper-V enlightenments. Running Windows 11 on the guest right now. I'm open to any suggestions :) VM Config: agent: 1 args: -cpu...

    Nested Hyper-V Virtualization Inhibits VM Startup

    I found a post on Reddit where a user was able to get Nested Hyper-V working on a Ryzen. https://www.reddit.com/r/VFIO/comments/ru4shi/ryzen_5000_series_hyperv_genshin/ Here is the XML provided for qemu, if anyone is able to work with this and incorporate into their own XML it could be worth a...

    AMD Nested Virtualization not working after 7.1 upgrade

    I think the nested virtualization issue is not related to GPU passthrough. (I am also ultimately going to pass through a GPU to my VM and was hoping to use Hyper-V's implementation of GPU-P). But to simplify the problem I created another VM with no GPU passthrough and the same problem occurs...

    Nested Hyper-V Virtualization Inhibits VM Startup

    When I launch AIDA64 it reboots the host with a 'Hypervisor Failure'. Nothing stands out in Event Viewer > System Logs for me to look further into, as far as I can tell. Before attempting to open AIDA64 the machine was up all night and didn't freeze

    Nested Hyper-V Virtualization Inhibits VM Startup

    I have enrolled in Windows 11 insider (developer channel), and am so far not seeing any freezing with Hyper-V enabled - 2 hours of stability now whereas this very same VM on the standard Win 11 build was freezing within 20 minutes or so. While this is the longest I've seen without a freeze, It...

    Nested Hyper-V Virtualization Inhibits VM Startup

    I read this article: https://docs.microsoft.com/en-us/virtualization/community/team-blog/2015/20151013-windows-insider-preview-nested-virtualization And this part made me wonder if the issue is memory related: So maybe turning off memory ballooning, and setting a static amount of memory to...

    Nested Hyper-V Virtualization Inhibits VM Startup

    I'm seeing this as well. Ryzen 3950x, Windows 11 host will freeze randomly with Hyper-V enabled. Usually the freeze will occur after ~20 minutes of being idle on the VM only, PVE itself is responsive. I'm also using kernel 5.15 which helped with booting the VM, but it is this final piece of...

    AMD Nested Virtualization not working after 7.1 upgrade

    I have a Ryzen 3950x and am having the same error after trying to enable Hyper-V. I've tried a few different kernels with the same results. Any suggestions?
