[Xen-users] Sharing success and fail VT-d based pass-through cases
Hello, all,>From the mailing list, I know many people are trying the VT-dcapability in Xen 3.2.x on various different HW (Intel Chipsets, motherboards, PCI cards, etc.). Why not let''s sharing our success story, as well as fail experience? Here are my success story: 1. On HP dc7800 (Intel Q35 Express chipset), successfully pass through a Linksys NC100 card to RHEL 3.7 i386 HVM with Xen 3.2.1 2. On HP xw8600 (Intel 5400 chipset), successfully pass through one of two onboard Broadcom NetXtreme BCM5755 Gigabit Ethernet (PCI Express) card to RHEL3.7 i386 HVM with Xen 3.2.1 And here are my fail cases, so far: 1. On HP dc7800 (Intel Q35 Express chipset), fail to pass through a PCI <-> IOBus Bridge card to RHEL 3.7 i386 HVM. The HVM with the card pass through crashes and continuously restart after created. Don''t know the reason and way to solve it. 2. On HP xw8600 (Intel 5400 chipset), fail to pass through a Linksys NC100 card to RHEL 3.7 i386 HVM with Xen 3.2.1 System hangs after create the HVM with the card pass through. The only PCI slot in xw8600 is within a nested PCI bridge, which also has the LSI SAS controller in. Maybe it''s the reason. 3. On HP xw4600 (Intel X38 Express chipset), fail to boot Xen if "vtd=1" option added to Xen. All the workstation above have the Intel VT-d option enable in BIOS.
