https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D241581 Bug ID: 241581 Summary: PCIe passthrough is broken in QEMU 4 due to PCI Device ID conflict Product: Base System Version: 11.2-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: kevo@gatorgraphics.com I run a couple of FreeBSD based VMs in Proxmox. Upgrading to Proxmox 6 which includes QEMU 4 broke the PCIe passthrough I had setup in both VMs.=20 On further investigation someone on the proxmox forums suggested that the problem is a device ID conflict. https://forum.proxmox.com/threads/vm-w-pcie-passthrough-not-working-after-u= pgrading-to-6-0.56021/post-274339 Apparently the QEMU vendor and device ids are being used for the ptnetmap-memdev device. https://svnweb.freebsd.org/base/release/12.0.0/sys/net/netmap_virt.h?view= =3Dmarkup#l44 https://devicehunt.com/view/type/pci/vendor/1B36/device/000C Any chance this can be fixed. I am currently having to run my VMs with an o= lder version of the Q35 machine in QEMU to make them work and I don't see any wa= y I can upgrade to later revisions until this is fixed. I suspect there are qui= te a few people affected by this. --=20 You are receiving this mail because: You are the assignee for the bug.=
