Hi,

I'm running the official Nextcloud VM (latest Ubuntu LTS) on my Windows 10 LTSC host. Ever since first installation, the VM crashes the host seemingly randomly during times of high I/O (large file transfers between VM and host over network). The crash occurs in a really weird way - the whole host completely freezes up, showing a constant image of what was last on the display before the crash. No pings, no way to get it runnung again, the only way to get out of it is to force reboot the host via the power button.

Here are the logs from VirtualBox: Is there anything unusual there? I don't think it's VM-related as I used the official Nextcloud image which is well maintained for this, but any help or suggestions would be greatly appreciated.

Thanks!

Hyper-V is enabled and might be interfering. See HMR3Init: Attempting fall back to NEM (Hyper-V is active). Try the VM again after you get Hyper-V disabled.

Disabling Hyper-V (turning the Windows feature off and rebooting the host) seems to have done the trick, thanks a lot!

Great! Glad you're up and running.
