Oracle VM Server for x86 uses a modified Xen hypervisor. Some legacy bug reports from 2018–2020 mention i915 errors inside Oracle VM DomUs (guests). However, ovmfrom is not a standard Oracle VM string. i915ovmfrom upd

Two interpretations exist for "OVM" in this context. Intel GVT-g allows a physical Intel GPU to

Solution: Reduce i915 verbosity:

echo 'module i915 =p' > /sys/kernel/debug/dynamic_debug/control

Or, if using printk:

echo "3 4 1 7" > /proc/sys/kernel/printk
