[Xen-users] PCI-passthru Infiniband card panics the domU at startup

[Yan Zhai <zhaiyan920@xxxxxxxxx>]

Dear sir,

    we are setting up a Xen-based computing environment, but one problem frustrated us: we can not use our Qlogic Infiniband network adapter in HVM mode, the domU kernel panic at the point of starting udev. I don't know what is wrong but actually I even have not installed the infiniband drivers when it panic, should a passthru device cause this?

  ÂÂ

    Xen hypervisor we used is the package along with Debian 6.0, with kernel version 2.6.32 patched with Xen source, and I started with 'iommu=1' argument. DomU OS is RHEL6, which boots and works all right without Infiniband card assigned. The logs, pci information and dom0 dmesg are contained in attachment (So long to paste them here).Â

   ÂSo can you give us some suggestions on how to activate the Infiniband card? Or do you know whether this kind of devices can be supported in domU?

thanks for help!Â
