I have been using vm-bhyve and PCI passthru for several years now on AMD CP= U. I am forwarding multiple LAN, WLAN and USB PCI cards to the various VMs. FreeBSD 14.3-RELEASE, 1 day of uptime, several (less than 10 IIRC) restarts= of VM. After few restarts of VM these messages start to appear in the syslog on VM start: ivhd0: Error: completion failed tail:0x570, head:0x20. ivhd0: Dump last 1 command(s): [CMD0, off:0x10] opcode=3D 0x1 0x28c3eb1 0x0 0xa5a5 ivhd0: Error: completion failed tail:0x620, head:0x20. ivhd0: Dump last 1 command(s): [CMD0, off:0x10] opcode=3D 0x1 0x28c3eb1 0x0 0xa5a5 ivhd0: Error: completion failed tail:0x6d0, head:0x20. ivhd0: Dump last 1 command(s): [CMD0, off:0x10] opcode=3D 0x1 0x28c3eb1 0x0 0xa5a5 Inside Linux guest, when passed-through PCI USB card work: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc.
