    Proxmox 7.4.1 crashing 10-15 mins after launching VM

    Hi, I have a number of issues with my server that started recently - I believe it shutdown due to a power cut while I was away (it does sit behind a UPS but auto-shutdown isn't setup).

    USB emulation - no option to disable

    Hi! Is there any future plan to add USB emulation to disable/remove per VM? usecase: QEMU USB device causes high context-switching (interrupts) inside a VM ( ex. freebsd ) thus high cpu load on the HOST. VM doesn't need to have emulated USB controller inside the VM, thus saving resources on the...

    Query/feature request Qemu args

    Thank you for all your work on Proxmox. It is my view a design/architecture requirement that each line within the VMID.conf should be shown somewhere within the GUI even if it is read only (vmgenid for example). This would help to ensure that all the settings can be checked by admin staff...
