[ovirt-users] Re: Viewing and hopefully, modifying the VM's qemu command line

Hello all, I'm setting up a fairly (?) complex oVirt over Gluster setup built around 3 Xeon servers-turned-into-workstations, each doubling as oVirt node + one primary Fedora VM w/ a dedicated passthrough GPU (+audio and a couple of USB root devices). One of the servers seems to have some weird issue w/ the passthrough nVidia GPU that seems to require me to edit the VM iommu (1) and passthrough device (2) command line. I tried using the qemu-cmdline addon to add the missing parameters, but it seems that qemu treats the added parameters as an additional device / iommu instead of editing the existing parameters. So: 1. How can I view the VM qemu command line? 2. Can I somehow manually edit the qemu command line, either directly or by somehow adding parameters in the HE XML file? - Gilboa. [1] iommu: VM XXX is down with error. Exit message: internal error: qemu unexpectedly closed the monitor: 2021-11-05T14:59:44.499366Z qemu-kvm: We need to set caching-mode=on for intel-iommu to enable device assignment with IOMMU protection. [2] GPU: May need to add x-vga=off,
